SOLAR TOWER SITE DEVELOPMENT UNDERWAY
Meteorological testing to confirm Bureau of Met eorology weather data will commence at the site of EnviroMission’s proposed Solar Tower this month.
Leighton Contractors Pty Ltd will commence the installation of site facilities including project offices and operational equipment at the site over January in readiness for MEDCO Pty Ltd who will manage the meteorological testing from February 2005.
MEDCO’s meteorological testing will provide quantitative data for EnviroMission and Leighton Contractors Pty Ltd to use to support early project findings and confirm existing Bureau of Meteorology weather data in
the area and specifically at the site for the world’s first Solar Tower power station in the Wentworth Shire of south west NSW.
Testing will involve measurement of ambient temperatures, wind velocity, solar insolation and vertical
temperature profiles.
EnviroMission Executive Chairman, Roger Davey, advises “the commencement of testing by MEDCO with
project management by Leighton Contractors is a vital event in the journey to commercialise a Solar Tower in Australia.
“Several markets poised to develop Solar Towers, primarily China and the USA, closely follow the progress of the Australia project and whilst this meteorological testing is site specific, the information and methodology will be generic to the overall development template.
“Testing at the site is also intended to further prove and strengthen critical design assumptions within the engineering case where they relate to weather patterns and conditions.”
This investigation coincides with the assessment of two technologies , previously announced by EnviroMission, for inclusion with the Solar Tower design – it is expected confirmation of the meteorological data will also benefit the evaluation of the technologies’ commercial case.
If successfully adapted to the Solar Tower, the technically and commercially proven technologies will substantially increase the efficiency and energy output in the region of 40% compared with original concept design estimates and will vastly reduce the collector zone corresponding in an overall reduction in capital cost.
The success of the pre-feasibility stage of the project concluded in February 2004, advanced operations towards detailed financial modeling throughout 2004 that included investigation of enhancements to the Solar Tower design to further increase output and decrease capital cost in order to deliver the strongest commercial model for domestic and global commercialisation.

Manu84 January 8th, 2005, 07:21 PM the idea is from spain!!
AtlanticaC5 January 8th, 2005, 07:30 PM Is it the one that will be 1000 m? Yikes.
Accura4Matalan January 8th, 2005, 07:33 PM Cool :)
STR January 8th, 2005, 07:54 PM Wow, this thing is actually going to be built. I assume from the article that this will be a generic design that can basically be copied and built anywhere, with minor differences in foundation, correct?
empersouf January 8th, 2005, 08:23 PM Great news.
james2390 January 8th, 2005, 08:48 PM Thats scary, but cool.:)
Taufiq January 9th, 2005, 12:29 AM I have a question.. it's kind of n00bish. :p For example the CN Tower right now is 553m, but it's not in any of the official WTB listings. So I am just wondering if the Solar Tower is going to be considered in the official lists:
http://www.infoplease.com/ipa/A0001338.html
http://www.emporis.com/en/bu/sk/st/tp/wo/
Islander January 9th, 2005, 12:36 AM It, like the CN tower, is not an office or residential building, so it won't be considered the world's tallest building. Tallest structure, on the other hand, yes. What an amazingly gigantic structure it would be if built!
DamienK January 9th, 2005, 12:38 AM Even though the walls are "only" 1 m thick - I wonder if the solar tower will have a greater volume of material than the great pyramid in Giza - 5.2 million tonnes.

Thanks for clearing that up. :)
STR January 9th, 2005, 01:20 AM Even though the walls are "only" 1 m thick - I wonder if the solar tower will have a greater volume of material than the great pyramid in Giza - 5.2 million tonnes.
The Great Pyramid's mass is in the area of 1,300,000 tonnes. The figure of 5.2 million tonnes comes from the blatantly wrong idea that the Pyramid is made from 2 million plus stone blocks averaging 2.5 tonnes. This is flat out wrong, computer models have shown that the Pyramid has, at most, 550,000 stones. This figure excludes the fact that 30,000 blocks's worth of volume is taken up by the Pyramid's core. The core is made from an outcrop of limestone bedrock, and is believed to displace the equivelent of 30,000 blocks.
eXSBass January 9th, 2005, 01:25 AM I don't know if i'm being picky. I know the solar thing will be in the desert conditions, and not really for attractions but can't it be a little prettier?
BTW - if this goes gold will they be mass producing them all over Australia?
baxter-rules January 9th, 2005, 02:41 AM the idea is from spain!!
Actually Germany. The whole concept and design is from a German designer, but the original test tower they built was in Spain and built with help from the Spanish Goverment. :)

the stacks were going to be painted pretty colours/patterns ect but this would prove to coslty to maintain. so it was decided to leave the finish as exposed concrete or similiar to a chimney stack.There will be 5 built in middle of Australia. one in most states.The centre of Australia is a dry arid place and perfect for the constant extreme heat needed to run the turbines for energy generation.
Homeroids January 9th, 2005, 05:49 AM Can we base jump off it when it is complete?
CrazyCanuck January 9th, 2005, 07:09 AM If Toronto is going to lose it worlds tallest title, I wouldn't mind it going to a project like this, help save the Earth.
demanjo January 9th, 2005, 08:36 AM Yeah it is great to see such an aggressive project, and as an added bonus, it is an environmental project!
I love this idea & cant support it more...
Surely will add to the tourism of the area... lol, no but seriously an observation deck 1km high would be cool, but wait, whats there to look at?
Woah.. these are the REAL questions facing mankind...
Trances January 9th, 2005, 09:04 AM hope it happens this is one of the best move australia has made for as long as i can remeber
renell January 9th, 2005, 09:06 AM the idea is from spain!!
gotta give credit to the ones implementing it :)
whats this one's exact height? :?
Smart_j January 9th, 2005, 11:36 AM Besides of using / producing solar energy it must be a great opportunaty for the outback to bring more tourists over. Basejumping from 1000m was mentioned before. What about climbing the chimney, for all those ignorant, respectless people instead of climbing Uluru to simply have that great view... Don't put it too close to it though. Heaps of space in W.A., don't u think?
Imperfect Ending January 9th, 2005, 11:53 AM 1000m!??!?!!?!?! thats like... tall!
Trances January 9th, 2005, 01:08 PM base jump ?
will all the bad events around this last year sure its a good idea
Citystyle January 10th, 2005, 09:41 AM They should build a 1500 Meter in the middle how awsome that would be.
Avatar January 10th, 2005, 09:44 AM Landing on thin acrylic/glass panels might end poorly. After all they would be hard to avoid considering they cover a vast area at the base.

Is that not enough to worry peolple and make projects like this be pushed a long
Citystyle January 10th, 2005, 03:16 PM Have not seen thos pics before, were they from?
Citystyle January 10th, 2005, 03:18 PM On the movie witht the station and train going up the tower, thats awsome if that happens it will be a huge attraction.
CULWULLA January 16th, 2005, 11:57 PM just a 1;1000 scale model i did of tower compared to some talls.
really shows the size of tower.

fahed January 17th, 2005, 12:40 AM Great idea indeed.
http://www.t-mation.com/images/print/enviro/enviro005.jpg
Where are the solar cells??
Taufiq January 17th, 2005, 12:57 AM just a 1;1000 scale model i did of tower compared to some talls.
WOW! :eek:
BTW, where did you get the other models? I wouldn't mind having some models of my favorite skyscrapers. :)
CULWULLA January 17th, 2005, 02:48 AM ^ i made them. im a model maker by trade.
fahed- the chimney is just a large vent where hot rises up to run turbines for the power.,
the solar collectors is the plastic "tent" which spans 7km diametre around tower.
its basic design. hot air rises under tent and rushes towards tower . thats basically it.

fahed January 17th, 2005, 06:52 AM Thanks for the explanation
I've found a website and it nearly said the same
http://www.floornature.com/worldaround/articolo.php/art269/1/en
This is a different type of Solar Towers
http://rhlx01.rz.fht-esslingen.de/projects/alt_energy/sol_thermal/powertower.html
I still got questions
Doesn't the air cool down after it reaches higher levels?
The article in the first link says
"reating an updraught which will drive 32 turbines located at the base of the tower"
Is that true that the turbines are at the base? If yes, then why do we need a very long tower ?
Sorry for asking a lot, but am interested to know more :)

Yes, I would assume it would cool a bit before reaching the top, but it would be travelling pretty fast.
They need the tall tower, as they need the top of the tower to be cool. Cool air at the top and warm air at the bottom causes the hot air to rush up and out. They need to build it high enough to reach the colder parts of the atmosphere.
demanjo January 17th, 2005, 09:44 AM Yeah, the higher the temperature differences, the greater the upwards thrust. Therefore, the higher the tower, the more lapse rate the atmosphere has succumbed to, and hence the greater temp difference -> more power.
BESTCITY January 17th, 2005, 10:04 PM Thats friggen huge.....
fahed January 18th, 2005, 03:27 AM Ok. What about the turbines? Where are they located ?
Tall Rog January 18th, 2005, 10:37 AM http://www.t-mation.com/images/print/enviro/enviro007.jpg[/img]
Looks like the turbines are at the base of the tower. But what happens if one breaks down? Who the hell is going to get in there and fix it. If the wind speed is so fast you are just going to get sucked up the vent.
Dam... how the hell do you quote an image!
Qatar4Ever January 18th, 2005, 10:41 AM Ive red about this about two years ago. I really believe in this project and hope it proves to be a success.

It's simple, you close the chimney and/or role up the tent...and away is the airflow. :)

Repair it overnight; solar plants don't function when it's dark.
EAT my SHORTS!!!!!! February 8th, 2005, 11:56 PM when is it going to start
MILIUX February 8th, 2005, 11:56 PM New challenge to Dubai. To build a 1001m structure.

:hahaha: :lol:
clive330 February 9th, 2005, 03:52 AM Repair it overnight; solar plants don't function when it's dark.
actually this one is meant to. They store thermal energy under the tent during the day so it runs at night.
Jue February 9th, 2005, 04:33 AM actually this one is meant to. They store thermal energy under the tent during the day so it runs at night.
All night? The airflow should die down to a whimper halfway through the night, no?
nezzybaby February 9th, 2005, 12:25 PM ^no!
NorthStar77 February 9th, 2005, 12:39 PM Not sure if it has been answered before, but how much power will this construction generate?
Malt February 9th, 2005, 01:38 PM It generates power for 200,000 homes (at any 1 time)
200MW ?
"EnviroMission’s inspirational program to adapt innovative Solar Tower technology to Australian conditions and construct the world’s first large-scale solar thermal power station is set to deliver a renewable energy solution that will also be a destination and extreme engineering icon.
The scale of the first 200MW power station will capture worldwide attention and attract significant added value through tourism and agribusiness.
View Video Clip (7 MB)
A single 200MW Solar Tower power station will provide enough electricity to power around 200,000 households, similar to the number of homes in a city the size of Hobart (capital of Tasmania) or Geelong (major suburb of metropolitan Victoria, Australia).
The energy output will represent an annual saving of more than 900,000 tonnes of greenhouse CO2 gases from entering the environment, with an outstanding Life Cycle Analysis of 2.5 years."
"EnviroMission’s Solar Tower is proposed to generate electricity 24-hours a day. The power station will be at its most efficient on the hottest days when energy is most needed and peak prices are paid for electricity.
Re-radiation of heat present in the ground under the collector zone will provide the energy source during the night. This special feature enhances the commercial viability of the power station and gives EnviroMission a consistent competitive advantage over other forms of renewable energy generation."
hella good February 9th, 2005, 05:24 PM wow, mega project!
its a bit of a shame that the future worlds tallest structure is so bland, its just a big chimney...
its a pity that our first 1000m object is not a building.
it is a good idea though and i think that it is likely to get built.
DUBAI February 10th, 2005, 02:29 AM is it made from concrete? if so surely it defeats the purpose of being eco friendly. i cant imagine the amount of c02 that would be produced from making all the concrete for this tower!
invincible February 10th, 2005, 07:42 AM Or imagine the CO2 required to produce 200 MW of power using coal!
Apparantly they have found a way to produce even more electricity out of the tower.
demanjo February 10th, 2005, 07:44 AM Raptor: The company acknowledges that it is not environmentally friendly to build, but what is?
Over the life of it however, it will cut down greenhouse emissions on the whole. That is the goal. Everyone realises that you have to do "work" to achieve the goal in the end.
NJANJA February 10th, 2005, 08:23 AM is it made from concrete? if so surely it defeats the purpose of being eco friendly. i cant imagine the amount of c02 that would be produced from making all the concrete for this tower!
"...with an outstanding Life Cycle Analysis of 2.5 years"
I don't know anything about 'Life Cycle Analysis', but I suspect that the above quote means that after 2.5 years of operation, the project has prevented as much C02 entering the atmosphere as was produced in constructing it.
DUBAI February 10th, 2005, 09:32 PM Ahh, ok i just heard that 54% of the worlds co2 comes from concrete, so i was wondering..
beyond 1000 February 11th, 2005, 12:38 AM The exact height is 1010m with an observatory at exactly 1000m. This is an answer in response to an earlier question on page one.
CULWULLA February 11th, 2005, 11:06 AM Hey i know its "just a chimney" but atleast its not belching out harmful pollutants, its just gonna be hot air which replaces green gases annually!
i think many people think this wont happen, BUT its gonna happen. It just takes time to plan its infrastructure. Constuction firms-Leightons have employed hundreds of workers who are soon to relocate out near Buronga, 30km north of Mildura.
todays story in NEWS!
Outback's solar tower will reach for the sky
10.02.05
MELBOURNE - The firm behind a plan to build a power-generating solar tower - touted as the world's tallest structure - in Outback New South Wales is to sign an agreement to buy the site.
Melbourne-based Enviromission will buy a 10,000ha slice of Tapio station at Buronga, 25km northeast of Mildura, to build the 1km tower.
Enviromission chairman Roger Davey would not confirm the purchase price, but said it was "more than A$1 million" ($1.1 million).
The agreement will be signed in Mildura, 550km northwest of Melbourne, before an audience of community leaders.
"This formalises the commitment between Enviromission and the vendor subject to planning issues, so we can move ahead with confidence," Davey said.
"It confirms our commitment to the site and the Sunraysia region for the first solar tower."
The mammoth project, worth hundreds of millions of dollars, will be built by the end of 2009.
The reinforced concrete tower will cover an area the size of the Melbourne Cricket Ground's surface at its base and will be surrounded by a "greenhouse" of glass, polycarbonate and polymer.
Air at 30C at the edge of the glasshouse is heated up to 70C at the centre, where the tower draws it through 32 turbines to the cooler air above.
The power station will produce up to 200 megawatts of electricity - enough for a city the size of Hobart - and can generate 24 hours a day.
Enviromission floated on the Australian Stock Exchange in 2001.
Its major investor is the owner of the solar tower technology, US company SolarMission Technologies.
Enviromission has the exclusive Australian rights to the technology, first developed on a much smaller scale in Spain in the early 1980s, using a German design.
A group of Chinese investors has formed a joint venture to invest a further US$2 million ($2.88 million) in the project's development.
There are also plans to invest a further US$8 million for development of a solar tower in China.
Enviromission will be a part owner of a global intellectual property company that will benefit from solar towers built around the world, Davey said.
The pre-feasibility study was completed successfully in February last year.

The 200MW Mildura solar chimney
The 1000m Solar Chimney in Buronga, Australia, will be the highest man-made structure on Earth, and can produce 200MW of electricity, providing power to 200,000 homes. The cost to build the tower is estimated at AUS$700 million (US$395 million), about 14 percent more than an equivalent coal-fired power station, and about 70 percent more per installed megawatt than a comparable wind farm. However, the investment will pay off in long term because it is more reliable than wind farm in sun-rich Australia and requires no fuel. By building the solar chimney power plant, the Australian government target of producing 2% of energy from renewable sources by 2010 (9500 GigaWatt hours) could be met easily.
Details of the solar chimney are as follows:
Location: Buronga.NSW, Australia
Type: Solar Tower power plant with steel-reinforced concrete tower and steel/glass solar air collector (alternatively with polymer glazing)
Features: The base of the tower will be between 170 to 200 metres. The chimney is basically a very simple tube with wall thickness of 25cm, diameter of 150m and a height of 1000m. The collector roof will be 5000m in diameter.
Power: Up to 500 Gigawatt hours per year
Company: Enviromission Ltd
Construction time: About 18-36 months
Expected completion date: 2009
demanjo February 11th, 2005, 11:23 AM Ahh, ok i just heard that 54% of the worlds co2 comes from concrete, so i was wondering..
Wow, that is a hell of alot. I would doubt this figure though...
But i havent heard otherwise, so i cant prove you wrong.
invincible February 11th, 2005, 01:27 PM Remember that coal and trees are pure carbon so when you burn them, all the carbon is released into the atmosphere as carbon dioxide. It also removes one molecule of oxygen out of the air for each atom of carbon burnt.
I don't think the production process for concrete would involve releasing that much CO2.
Archiconnoisseur February 11th, 2005, 02:21 PM If this thing works, it could be great for parts of Africa and the Middle East; maybe even the desert Southwest of the U.S.
CULWULLA February 11th, 2005, 03:32 PM just a quick diagram showing how big S0lar tower really is compared to some world talls.

demanjo February 11th, 2005, 03:48 PM I love your little illustations like that Cul, really shows you how ridiculous the structure is, even when against Burj Dubai (i notice its not the 900m speculated height tho, either way it is still dwarfed).
Archiconnoisseur February 11th, 2005, 03:53 PM It seems like a waste to build such a massive structure to serve as just a convection tower. Why not add offices on its surface or use it to boost rockets off the ground (i.e. railgun)?

Heh, interesting idea. The offices perhaps wouldn't really work, as this tower is literally in the middle of nowhere - not many people around to occupy the offices :)
As for the rocket-launching idea, of course the costs involved would be an issue. Also, the logistics of transportation of stuff out to the tower - over the many kilometres of greenhouse - would be quite a challenge.

The other use is for agriculture, you've got a huge greenhouse at the base of the tower.
tritown February 12th, 2005, 09:35 PM Has anyone said how big the base is?
Jue February 12th, 2005, 10:45 PM The other use is for agriculture, you've got a huge greenhouse at the base of the tower.
Considering the greenhouse is stuffed full of plants in the renders, they must already be planning for agricultural uses.
neilio February 13th, 2005, 01:12 AM that is simply amazing, i cant believe the size of that thing! to bad its only a big chimmey thingy and not a building or skyscraper, then australia would REALLY have something to brag about!!
Archiconnoisseur February 13th, 2005, 08:41 AM Heh, interesting idea. The offices perhaps wouldn't really work, as this tower is literally in the middle of nowhere - not many people around to occupy the offices
Definitely, but I was sort of thinking that this would be a self-contained vertical city. Homes, schools, shopping, etc, all on the sides of this tower. Brasilia, I recall, was plopped down in the middle of nowhere.
As for the rocket-launching idea, of course the costs involved would be an issue. Also, the logistics of transportation of stuff out to the tower - over the many kilometres of greenhouse - would be quite a challenge.
A railgun is supposed to be far cheaper than rocket power. A tunnel could easily be built to pass under the greenhouse portion. Think how big Fermilab and CERN are.
Anyway, it's just an idle thought. The cost to reinforce the tower in order to handle these additional uses might be prohibitive.

The best rocket launch sites in Australia are closer to the equator in our tropical north zone - they wanted to build a large space port up near cape york and christmas island... I'm not sure they would get the same effect from a launch site so far south.
Grollo February 14th, 2005, 04:49 AM The 1000m Solar Chimney in Buronga, Australia, will be the highest man-made structure on Earth, and can produce 200MW of electricity, providing power to 200,000 homes.

I think this is a fantastic project, but some of the figures they are using are, unfortunately full of shit :-)
The new 1000 megawatt gas fired plant which is to be built in western Victoria (not that far from the Solar Tower) will only cost $1 billion dollars or $1 million dollars per megawatt. The solar tower will cost 3.5 million dollars per megawatt.
The new 900 megawatt Callide Clack Coal Power Plant in Queensland cost only $800 million.
That's why nobody has built a solar tower between the time the first successful tests were conducted in the 1980's and today because economically speaking, without massive government subsidies, it just doesn't stack up.
Grollo February 14th, 2005, 04:54 AM Austrlia's largest wind farm at Portland, also in Western Victoria will produce 195 megawatts and cost only $270 million.
Also the Victorian government has allowed hazelwood (the states largest coal fired plant) to continue operating until 2031) and is considereing three new proposals with a combined capacity of 2500 megawatts using brown coal turned into gas in addition to the natural gas fired plant.
With all this extra capacity coming on line in the next few years the Solar Tower will find it impossible to compete, even with huge subsidies.
By 2010 Victoria will produce more greenhouse gas emissions per person than any other region on earth.

There certainly could be subsidies; such would be quite normal.
Grollo February 14th, 2005, 06:32 AM Yes but you have to remember Australia is one of only two countries NOT to ratify the Kyoto Protocal because we have the worlds largest reserves of cheap brown coal, which is the most polluting form of power known to man :-(
demanjo February 14th, 2005, 09:04 AM Grollo, just in reference to your statement about the 195MW wind farm -
In some aspects, while cheaper, the wind is not the best choice. Even the most productive areas of wind only produce about 50% of the time, and it is not always at maximum capacity.
The solar tower is so attractive because a) it is an engirneering marvel, but also b) because it mimicks society's patterns of electrical use so well. It is at the highest production mid afternoon, when the most airconditioners are on & demand is the highest. It is also reliable, the sun will keep shining. The company is always guaranteed electron movement.

So was our capital, Canberra.
CULWULLA April 8th, 2005, 03:05 PM guys, latest word is that the Solar Tower has been reduced i size. due to costs/engineering logistics ect ect.
so now maybe 500m tall?
heres a quick diagram i did over in oz section compared to some talls. it might be taller then 500m but ill show it at half height for now. hopefully we will here something more "concrete" soon.

TallBox April 8th, 2005, 03:28 PM disappointing.. :(
it's little more than just another chimney now
Trances April 8th, 2005, 04:23 PM boooo !
but as long as it happens
Monkey April 8th, 2005, 07:25 PM Oh well, at least we still have Burj Dubai to look forward to, which will be almost as tall as the original planned solar tower.
Johan April 8th, 2005, 08:21 PM But i dont really understand why it has to be of concrete, cant they just use any air-tight material? like some kind of industrial grade plastic? and if the rush of air gets stronger the greater the diffrence in temperature is. Why not connect that long plastic tube to a satellite in geostationary orbit? please excuse my ignorance, im not an engineer... :cry::runaway:
Urban Dave April 8th, 2005, 08:32 PM Johan, you sould leave hard drugs !!!! XD XD
nezzybaby April 9th, 2005, 02:23 PM i feel dissapointed that this has happened, but as id been saying all along thisll never get built to 1km also slightly smug. its a shame, but do we really want the biggest building in the world to be a chimney???
Citystyle April 9th, 2005, 02:37 PM A 1000m solar tower will happen.
Expect one after the 500m if its sucsessfull.
Bahraini Spirit April 9th, 2005, 03:14 PM so what's the latest with this?
RUM April 10th, 2005, 05:32 AM The one thing I still can't undertand is how this thing will stand up.
Look at the foundations that are required for the Burj, now considering this thing is going to be 1000m high, yet there needs to be fans underneath the giant structure to let the air go through, how can this all work??
beyond 1000 April 10th, 2005, 08:04 AM Oh Well!
I was looking forward to 1000m.
Burj Dubai will break 800m and that's not all that bad.
Avatar April 10th, 2005, 10:12 AM Why bother with a 500m tower? It's pointless IMO - the power output will be less than ideal and it will achieve nothing as far as iconic status goes - who cares about a 500m chimney, it's hardly and earth shattering development now. Sure it may be a stepping stone but really I don't see the value in it now. If i was local council or state government, I'd revoke the the application to build. No news could be more deflating than this, to people of the area, with their hopes of something fantastic.
Well for Australians this is a slap in the face IMO. If they can't build it to the original specs - i'd rather not have it at all, broken dreams and promises. It really sucks. How short-sighted and what a cop-out. It's nice to see we will end up with an 800m tower in Dubai but this does nothing to aid Australia in it's quest for some engineering marvel.
CULWULLA April 11th, 2005, 02:30 AM The 500m stack will still have an external lift and 500m high observation around its rim. As citystyle says, a 1000m version will definatley happen but maybe in China or elsewhere. money seems to be a problem with Australian projects.?
Anyway ground clearance has started in Buronga and leightons contractors are setting up housing and new road net works ect. Also a major concrete plant will have to be built to service the stack.
I know it wont be as high as Burj Dubai but it still will be just as impressive. remember BD will end up a pinnacle at 500M+ make upwards. the Solar Tower is 80m Diametre whole way up!!!!
Bahraini Spirit April 11th, 2005, 02:43 AM Cool thanks for the clarification. So, maybe in another year to year n a half, this one should be u/c.
Trances April 11th, 2005, 04:13 PM well so China might have the title after all !
Though it would remaind with Dubai for some time
year and half to wait till is starts
Still plenty of time for it to be canned by Australia
Nightsky April 11th, 2005, 05:24 PM Have heard about this. It could be the first structure to pass the 1 kilometer border if they didn't scale it down!
dylane April 21st, 2005, 03:22 AM I'm doing a presentation on the solar tower for a class tomorrow and this is the first I've heard about the reduction in scale. Does anyone have a link to an article that mentions this? The EnviroMission (http://www.enviromission.com.au/) website still shows it being 1000M, and I wasn't able to find a mention with Google News either. Any help would be very much appreciated.
Thanks,
Dylan

I don't think you would even need to do that, the wind is only estimated to be 35mph, which really isn't that strong, at least not strong enough to suck up a human I think...but I'm no physicist, so what do I know. ;)

Oriolus April 21st, 2005, 07:07 AM Dylan - Culwulla broke the news about it being reduced to 500m and he heard it on "the grapevine" so its not official yet - most people wouldn't know. I'd just say its 1000m but maybe mention that you've got a couple of contacts and there is a possibility it will be reduced to 500m because of financial viability concerns. ;) You might get some extra marks for having the inside info :)

Thanks Oriolus. I wonder what reducing the size to 500m will do to the power production/cost ratio. I know solar towers are supposed to gain in efficiency as the heighth increases, so I'd guess the cost per kwh would increase greatly. My presentation is a "pre" cost-benefit analysis of the tower...cutting the thing in half might influence my results a bit. ;)
I do appreciate the info though, and I'll just have to keep an eye out for an official announcement when it comes. Thanks again. :)

Cheese Mmmmmmmmmmmm April 22nd, 2005, 08:34 AM I don't mean to sound cynical, but I'm happy the 1000m tall solar tower isn't being built [yet].
My reason? Because I'm looking forward to having the tallest freestanding man-made structure on Earth being a habitable building, not some inhabitable tower, antennae or concrete cigar.
GO BURJ DUBAI!!!

slickpenguin May 3rd, 2005, 05:10 AM Great idea! Every country with great land mass should consider the same. Canada? US? China?, etc. Hope it works and becomes a propagating reality. I love Auz.
rocky May 7th, 2005, 12:02 PM shame that it doesnt have 1000meterS.
and look at the possibilities.. imagine 1000 of these towers in the sahara,arizona, gobi, kazakstan; the effects on pollution reduction would be amazing
EleGance May 7th, 2005, 05:40 PM superb!!
fiedag May 11th, 2005, 07:15 PM Culwulla where did you hear this? Is it certain? Also have you heard that the inner 300m or so of collector are to be double-glazed?
Cheese Mmmmmmmmmmmm May 11th, 2005, 10:40 PM Solar power at best can only produce a small fraction (like 10%) of the world's present energy consumption. However it's a great "transition" renewable power source to get us between the end of oil and the rise of hydrogen. :) :)
CULWULLA May 12th, 2005, 05:36 AM Culwulla where did you hear this? Is it certain? Also have you heard that the inner 300m or so of collector are to be double-glazed?

demanjo June 17th, 2005, 12:41 PM Really, solar if unbelievably aggresively pursued, could easily supply enough energy for the world. We would just need kilometer big arrays, and they would be expensive as hell.
Cheese Mmmmmmmmmmmm June 17th, 2005, 05:16 PM ^ True, there's something like 175,000 TeraWatts of energy that makes it to ground level Earth. The problem is, utilities are in the business of making money, and costly investments into solar arrays this big that only produce 200MW aren't attractive (yet). This one in Australia's going in a desert right? Most places on Earth don't receive as much sun as a solar tower would require to operate semi-consistantly. And then there's the cost of transmission from the desert to customers. The economics don't seem to add up just yet. :)
As for the aesthetics, I think it would look a million times better if they placed mirrors along the outside of the entire tower. Perhaps it'd even disappear from sight on clear days! :cheers: :cheers: :cheers:
demanjo July 29th, 2005, 02:00 PM Not sure if this has been posted anywhere. It appeared on Enviromissions site about a month ago, but ive only noticed it now.
Anyway, the article seems old, but is OK.

thunder head July 29th, 2005, 02:34 PM are they seriously gonna build it to just 500m????? That's so shit here we have the oppurtunity to build a mega-structure now just think people are gonna want to see a 1km tall tower and it would launch the Mildura area to world fame for sure! Just imagine the income we'd get from tourism etc.
Now a crap 500m dildo isn't gonna impress anybody. 500m and it won't be recognised anywhere. 1km and everyone in the world will know about it. And we could be proud of our selves for achieving such a feat Australia would finally have a world mega-structure.

rock the foo July 30th, 2005, 12:00 AM so there only gonna build it to 500m? man, why so short?
nezzybaby July 30th, 2005, 01:51 PM ^Why does everybody think 500m all of a sudden.... an off hand comment by someone probably a wind up suggested it may be halfed in height, yet every press release, website and other official information says 1km. However im still very skeptical as to whether itll get built at all, seems ludicracly expensive for a 200mw power plant.
Citystyle July 30th, 2005, 09:02 PM it matters not if it's 500m or 1000m because if it works expect 1000m+ in the long run. Mabey 500m is better for ecenomic wile they are developing and testing.
nezzybaby July 31st, 2005, 02:34 PM 500m would produce a higher temperature at the top of the tower, and hence a lower temperature gradient. This would cause a lower power output, probably less than 100MW which would make this project even less economically viable.
CULWULLA September 28th, 2005, 02:41 AM well the latest from Enviromission is that a scaled down 50mw solar tower is now being designed and should be up and running within a few years. No word on new height but i reckon at 1/8th volume neede for 50mw would be 500m at 65m dia. (its only my guess)

Project optimization (completed)
Pre-Feasibility Commercialisation (completed)
Final Feasibility (underway)
Final Design and Construction
Construction
Commercial Operation
EnviroMission is currently in the final feasibility phase of development which involves collaboration and project partnering to validate the economics of the project. The collaborative approach has also been central to harnessing critical technical expertise and resources to further progress the development of the technology in Australia

mic of Orion September 30th, 2005, 09:09 PM latest news on Australia's 1000m Solar Tower
www.enviromission.com.au
SOLAR TOWER SITE DEVELOPMENT UNDERWAY
Meteorological testing to confirm Bureau of Met eorology weather data will commence at the site of EnviroMission’s proposed Solar Tower this month.
Leighton Contractors Pty Ltd will commence the installation of site facilities including project offices and operational equipment at the site over January in readiness for MEDCO Pty Ltd who will manage the meteorological testing from February 2005.
MEDCO’s meteorological testing will provide quantitative data for EnviroMission and Leighton Contractors Pty Ltd to use to support early project findings and confirm existing Bureau of Meteorology weather data in
the area and specifically at the site for the world’s first Solar Tower power station in the Wentworth Shire of south west NSW.
Testing will involve measurement of ambient temperatures, wind velocity, solar insolation and vertical
temperature profiles.
EnviroMission Executive Chairman, Roger Davey, advises “the commencement of testing by MEDCO with
project management by Leighton Contractors is a vital event in the journey to commercialise a Solar Tower in Australia.
“Several markets poised to develop Solar Towers, primarily China and the USA, closely follow the progress of the Australia project and whilst this meteorological testing is site specific, the information and methodology will be generic to the overall development template.
“Testing at the site is also intended to further prove and strengthen critical design assumptions within the engineering case where they relate to weather patterns and conditions.”
This investigation coincides with the assessment of two technologies , previously announced by EnviroMission, for inclusion with the Solar Tower design – it is expected confirmation of the meteorological data will also benefit the evaluation of the technologies’ commercial case.
If successfully adapted to the Solar Tower, the technically and commercially proven technologies will substantially increase the efficiency and energy output in the region of 40% compared with original concept design estimates and will vastly reduce the collector zone corresponding in an overall reduction in capital cost.
The success of the pre-feasibility stage of the project concluded in February 2004, advanced operations towards detailed financial modeling throughout 2004 that included investigation of enhancements to the Solar Tower design to further increase output and decrease capital cost in order to deliver the strongest commercial model for domestic and global commercialisation.

I figure the way this thing works it will have a great effect on the winds and temperature variations in the surrounding area, and I thought australia was a stickler for such environmental things
Bertez October 1st, 2005, 05:38 AM Doesn't matter if it is 500 or 1000 metres, this thing is going to be sweet
thunder head October 1st, 2005, 05:45 AM 500m, that's shit. Not an accomplishment, but more a standard project. why doesn't it surprise me that yet another proposed mega-project in this country is dumbed down? The original 1000m design would be a real accomplishment.
Perth4life3 October 1st, 2005, 05:49 AM id like to see you build a 500 m solar tower.
Canadian Admiral October 1st, 2005, 05:33 PM height is not the main achievement here, the fact is that this is a very efficient way of harnessing solar energy, and it is completely renewable too. An entire network of these things dotting the outback can power the commonwealth's energy needs for the next 500 years.... Especially if coupled with hydrogen production, australia will be on the upswing if this goes through.

As far as I know there are Chinese investors who have already sunk a few millions into this project. So I reckon the full scale version could be built in China soon??
Superfish February 1st, 2007, 05:06 AM I wonder if it will have an observation deck :) :) That video shows it could.

nezzybaby February 2nd, 2007, 02:23 PM this concept really pisses me off, do you understand how much CO2 will be generated during its construction? The power output is pathetic for such a massive structure, 50MW is a joke, a single 100m wind turbine can currently produce 6-7MW of power, and would take up considerably less space and resources. The term renewable is misused in this context, it will probably take about 30 years before the amount of co2 created by this product falls under that from a coal power station of similar power.
"imagine a big city poweed by a couple of these"
will never happen, you'd need litterally hundreds of them to power a small city let alone a large one. New York uses around 150 GW which would require 3000 of these solar towers.
Its a novel interesting concept, but not the solution to global warming or the world energy crisis.
RickyBobby February 2nd, 2007, 03:10 PM Your just jealous because you could never build one of these in london/manchester NO SUN.
When there is no wind, wind turbines dont generate engery but the solar tower even works at night.
And the CO2 generated during the construction of one of these towers would be far less that a conventional power station or a building of the same size for that matter.
I dont know what your talking about man.

I dont know what your talking about man.
He's right though, 50MW is hardly anything, especially when you consider the size needed. By comparison, a fusion power plant (currently under development in France) could potentially generate gigawatts of power.
If they're going to build one of these things, at least make it the 200MW+ version.
Incidently, why should he be "jealous"? London already has plenty of amazing projects thank you...
TroyBoy February 2nd, 2007, 11:09 PM DOesnt sound very economical, imagine how much it would cost to build, and how long it would take to break even.
ZZ-II February 3rd, 2007, 11:08 AM you need a very tall tower that this project will be economically.
Charles Dubai February 5th, 2007, 07:09 AM WOW ITS AMAZING!!!!!!!!!!!!!!!!!!!!!!!!
TopperCity February 5th, 2007, 07:46 AM Salar energy is way to go, free and clean. Who cares about some CO2 being generated during the construction? Given the energy produced is not covering the entire NY city but benefiting the area substantially, this should be a good start, even a major milestone. Nevertheless, this will give way to a better and more efficient technology for that matter in the next projects to come.
Thanks for such a valuable thread.

Not 50, but 150 MW (145 the tower plus 5,5 the biomass plant working with the biomass produced by the fields in the base of the tower, under the solar panels).
EDIT to clarify: I'm talking about the 750 m Solar Tower whose construction will start this year in Spain.
vid February 15th, 2007, 11:53 AM 150MW out of a 750m eyesore isn't worth the cost to the environment that a 750m tall tower will provide. The area you have to clear for solar power alone cancels out it's efficiency. It's good on top of buildings, but as a sole source of energy? No way.
ZZ-II February 16th, 2007, 11:20 PM hopefully we'll see some updates from the 750m tower :), that tower will be the 2nd tallest structure on earth when completed!!
Alweron February 17th, 2007, 12:24 PM Geez, my guess was that in the next 10 years they would build a one kilometer-high tower. I had no clue they are already planning it so soon. That's awesome. I bet the people in Dubai will be pretty pissed of since they are building the highest one now. Then only few years later there will be even higher tower.
Scruffy88 February 17th, 2007, 07:15 PM i hate to sound so pessimistic, but i'll believe the tower in Spain when there is an above ground structure slowly growing
Don Omar February 18th, 2007, 05:14 AM agreed^^

EnviroMission promises power from hot air

Going up: design sketch of the giant thermal solar tower EnviroMission plans to build.
ENVIROMISSION is the sort of company that can enrich or burn investors in alternative energy sources — often within one day.
The South Melbourne company plans to build giant solar thermal towers to generate electricity in Australia and the US. News it had collected favourable pre-feasibility information in Texas, sent its shares soaring 79 per cent last Monday to 25¢.
The shares sank back to close the day at 20¢, the highest price in almost a year save for a short-lived 80 per cent spike in October. That blip was based on misguided speculation the company would benefit from a $75 million federal grant.
EnviroMission shares closed at 18¢ on Friday, less than half the peak of 40¢ reached soon after the company listed in 2001.
Analyst Peter Strachan, who publishes the StockAnalysis newsletter, said investors should be wary of such volatile "clean and green companies", labelling them "the new dotcom".
EnviroMission adapted German technology for a base-load station that would generate electricity using solar-heated air.
A canopy with a diameter of five to seven kilometres uses the the sun to heat the air trapped below. The heated air rises, rushing up a kilometre-high tower equipped with turbines.
Chief executive and executive chairman Roger Davey said although final plans had not been drawn up, construction should begin this year on the first power station near Mildura, NSW,Australia.
Solar radiation data has been collected at the Mildura site and EnviroMission will continue collecting data at two sites in Texas and two in Arizona. EnviroMission would go to the market again to fund construction if required, Mr Davey said.

Alweron February 19th, 2007, 11:33 AM I should've read that text much more carefully. That's no skyscraper, it's only some weird "jimney". I guess that's something too, even tho it's nowhere near a skyscraper.
aussiescraperman February 19th, 2007, 11:45 AM ^^ u just realized that? but if it gets built at 1000m, it will get tallest man made structre at least.
so, Cul, i don't understand, is it still possible buruonga will get the 1km one? according to that diagram it will.
cheers
CULWULLA February 19th, 2007, 12:08 PM ^old diagram. its since been scaled to 500m high. 50mw.
still higher then any chimney or skyscraper (except BurjD).

James R. Hawkwood April 20th, 2007, 11:09 PM Nice huge tower and it is usefull too!!!
But i have some doubts about it... Isnt it what large?? What is the netto output off this thing?
If the output is huge then i understand it that it is so large. If not.... decide for your self...
googlepeakoil April 21st, 2007, 07:46 AM Solar power at best can only produce a small fraction (like 10%) of the world's present energy consumption. However it's a great "transition" renewable power source to get us between the end of oil and the rise of hydrogen. :) :)
The earth receives energy from the sun in 3 days equivalent to all the energy reserves of oil in the world. So many thousands of times what the earth uses each day. I dont' know where 10% comes from.... if they built enough solar towers Australia could export electricity around the World.
googlepeakoil April 21st, 2007, 08:03 AM this concept really pisses me off, do you understand how much CO2 will be generated during its construction? The power output is pathetic for such a massive structure, 50MW is a joke, a single 100m wind turbine can currently produce 6-7MW of power, and would take up considerably less space and resources. The term renewable is misused in this context, it will probably take about 30 years before the amount of co2 created by this product falls under that from a coal power station of similar power.
"imagine a big city poweed by a couple of these"
will never happen, you'd need litterally hundreds of them to power a small city let alone a large one. New York uses around 150 GW which would require 3000 of these solar towers.
Its a novel interesting concept, but not the solution to global warming or the world energy crisis.
the company quoute a 2.5yr payback not 30 years.
a 6MW wind turbine has a 135m diamater blade sweep - and would only be expected to generate at 40% capacity due to wind conditions.
I haven't seen 50MW quoted anywhere - it might surpass the proposed any proposed MW exceeding expectations - so they should build the concept anyway.
I think there's room for wind and solar - but 20 or whatever MW equivalent wind turbines take up a lot of space too
I think the American's are silly to only now be talking about renewable energy generation and looking at wind and solar seriously because now they can use the term "energy security". Before those 2 words were added nobody wanted to look at renewables...
dubaifan8 April 21st, 2007, 07:28 PM they should have kept the 1000m version:ohno:
CULWULLA July 16th, 2007, 01:15 AM july update!
looks like Australia is still forging ahead with its solar tower. latest figure is quoted at 600m high! or 1800ft which is actually 550m.

The 2.5 yr quoted by the company is for cost not CO2 emission. 135m means that you could fit 23 in a line accross the 2 mile diameter of the solar collector for a solar tower. If each was a 6MW wind turbine then the total would be over 120MW, at 40% generation this is equivalent to the 50MW solar tower, it would require much less raw materials, generate considerably less CO2 during production, and be much less of an eyesore than a 600m concrete tube.

http://www.solucar.es/
nezzybaby July 16th, 2007, 10:16 PM ^that project is completely different to this one. The solar tower works by drawing air through a tube, creating power by turning wind turbines. The project in Seville focusses many beams of light on a single point generating a massive ammount of heat which is used to boil water and turn a generator with the steam produced. Dont get them confused.
jaaar July 16th, 2007, 10:35 PM a similar tower has been already built in Seville
not trying to confuse anyone :ohno:
CULWULLA July 17th, 2007, 05:11 AM thanks for that jaaar. nice project.
yes we all wanted it to stay at 1000m but it was too large an undertaking being 130m diametre. so its scaled back to 600m @ 65m diam. it will have a observation circle at top. not bad being up 600m with sheep paddocks below.lol
it supposed to start this year. the site has been cleared,.
heres an old diagram i did to show how hUge the tower will be

Trances July 17th, 2007, 10:28 AM Thanks for pointing that out nezzybaby
CULWULLA July 17th, 2007, 12:27 PM has it been decided yet
its been given council and state gov approval. the site has been cleared. All it needs is funding $$$$$. The glass canopy covers a few hectares but only needs to be 3metres high. Then the concrete tower is 1m thick x 65m diametre. with enormous steel spokes inside at 100m intervals and large turbines creating the power. There will be an elevator attached to side rising up the the rim which will have an observation ring some 600m above grd. maybe even worlds highest public viewing? but not much to see out there.
The Australia version will be approx 600m while Spain has mooted a tower 750m high while China and USA may end up with 1000m version?
I think 1 of these towers will be built within 10 years.

aussiescraperman July 17th, 2007, 04:02 PM wat official classification will this tower be classified as. will it just be a tower?
what are the definitions of a skyscraper..does it have to have continuing floors from base to top? or wat.
cheers
CULWULLA July 17th, 2007, 05:25 PM I think it will be classified as a chimney actually. It doesnt let out pollutants like power station chimneys but its sole purpose is for hot air to pass up it to run turbines.Chimneys dont have observation due to obvious reasons but Solar Tower has clean air and observation ring will be encased in glass with air cond anyway.

That would be awesome. We could build thousands of those over all the useless states (you know, Idaho, Montana, etc), and be completely independent from oil. :)

Green Jello July 20th, 2007, 01:19 AM That would be awesome. We could build thousands of those over all the useless states (you know, Idaho, Montana, etc), and be completely independent from oil. :)
Those states don't get anywhere near enough sunlight to make them cost effective. These would only work in the US in Arizona, Southern Nevada, etc.
xXFallenXx July 20th, 2007, 01:49 AM idaho and montana routinely have temps. over 100 in the summer so i think it would be very plosible to build some of these in that area. there is so much open space there we could build dozens of these and that would be enough to power some nearby states. we could also build some in the desert areas in California, Arizona, and Texas to power (or at least help to power) those states as well. as to the FAA not letting us build these, i think that they dont really have a choice. we need clean almost unlimited energy and they are starting to realize this.
CULWULLA July 20th, 2007, 01:57 AM i posted the american info a while back. looks like a couple of sites in Ward County Texas are earmarked for towers.
If USA has 610m/2000ft height limit, then maybe the solar towers will be limited to that height.?\ This is the height the Australian towers will be. Maybe they have worked out it will be "good enough" at that height instead of 1km.? Obviously it will be a cheaper more do-able option and more realistic.
here is some recent letters about USA Towers>

xXFallenXx July 20th, 2007, 03:36 AM so i was wondering.................could you cover the surface of one of these things with solar panals? the surface area of one of these chimneys would be huge so instead of just concrete you could use solar panals to increase the energy output even more.
aliendroid July 20th, 2007, 04:07 AM That would be awesome. We could build thousands of those over all the useless states (you know, Idaho, Montana, etc), and be completely independent from oil. :)
1st, idaho and montana are not useless states but that's pretty typical of someone from the northeast and 2nd we wouldn't want our country full of these, I hope a few large ones are built (one in texas) for the sake of being able to compare them later to other sources of power and for the sake of progress but wind mills are much less of an eye soar. Texas is the leading state in the USA in wind power and they are installing a whole lot more this year. I drove to lubbock 3 months ago and just a few days ago and between that time and now they managed to build an entire large wind farm within a few miles of the road and I saw new wind mills being constructed on all of the already existing wind farm sites that I went by and texas also boasts the largest wind power plant on earth. In lubbock they actually have one large electric wind mill within the city!
My solution to the energy problem is to use wind power in large wind farms and use solar only on roof tops of homes and buildings. Also if you take the graph of the power production during the day for the wind mills that put power into the texas grid for example it won't be a perfectly straight line, which is a problem-- you need to maintain the capacity of peak power usage in reliable sources but there is a solution to that problem as well. You look at the graph of the power produced over a long period of time and find a horizontal line where you have at least that much power 90 percent of the time (That is 90 percent of the time the wind mills combined are producing at least this much power, let's say that reaches 50,000MW some day although total capacity could be 150,000MW), then anything below that goes into the grid and anything above that or anything that isn't otherwise used goes into hydrogen production through electrolysis. Then build enough hydrogen burning or hydrogen cell power generators that can produce 50,000 MW in case you have a windless day all across the state. Now to make up for the fact that there is more power demand during the middle of the day and wind power is slightly less in the middle of the day then at night, solar panals come in very handy and if they are distributed on roof tops (including industrial buildings) they can help reduce power demands during the day (esp middle of the day) significantly.
So I think that building huge numbers of large scale solar power plants isn't the best way to go but it would be nice if a few are built.
aliendroid July 20th, 2007, 04:11 AM so i was wondering.................could you cover the surface of one of these things with solar panals? the surface area of one of these chimneys would be huge so instead of just concrete you could use solar panals to increase the energy output even more.
wouldn't be worth it, the tower is vertical and the point of the day where sunlight is most intense is when the light would be moving almost parallel to the surface of the side of the chimney, thus producing no power.
xXFallenXx July 20th, 2007, 04:23 AM ^^ thanks. i kinda agree. i think that instead of just having large solar towers we should have a combination of large towers and houses with solar panals on top. if every house was built with solar panals the houses would be completely self-sufficant (energy wise) and we could build the large towers for factories and office buildings.
Muse July 20th, 2007, 04:30 AM It's also based on the fact that heat rises (captured under the huge solar-paneled disc, thus spinning the huge turbines @ the base passing thru the generators within the stack producing the power) so the further up you go, the lesser gained anyway - wouldn't be quite as practical or $$$s viable. Would make it look reeeeally classy though ;)

Plenty of industrial sites, schools and office buildings in California already have solar power systems in use on the roof. They normally can't produce all the power they need but at least they reduce the amount of power they take from the grid.

It has little to do with how hot the summer gets. It's more about the entire year. The location in Australia where this is planned has over 300 days of sunshine a year. Even though they would work very well in the Idaho and Montana summers, they would be almost useless for half of the year. Also, I would imagine the closer to the equator, the better.

Although Germany has a lot more wind power overall then texas does, the Horse hollow wind farm near abilene with 735 MW of capacity is the single largest wind farm on earth today, but there's an oil tycoon here that's planning a wind farm that will produce about 4000MW

Avatar July 21st, 2007, 02:40 AM Wind power is such a blight on the landscape. TIMO they shold be outlawed for their visual pollution. Not everyone may agree but I think wind turbines look worse than a nuclear plant.
xXFallenXx July 21st, 2007, 02:43 AM i think that they should put wind turbines out in the oceans. they could make thousands of them and most people would ever see them.
aliendroid July 21st, 2007, 02:44 AM wow 4000MW thats crazy. you wouldnt think an oil tycoon you want a wind farm.
Actually a lot of them are smart enough to be investing into it in texas. The land is leased by the rancher (who often is an oil tycoon as well) at about 3,000 to 5,000 bucks per wind mill per year. Imagine putting 2000 wind mills on your land.
$3,000 * 2,000 = 6 million bucks per year.
A lot of people don't realize that the oil here in texas isn't going to last very long but a lot of oil tycoons do realize this.

aliendroid July 21st, 2007, 02:52 AM that makes sense.
Actually he'd make more then 6 million dollars per year because he won't be the land owner, he'd own the company that delivers the power. The 3,000 to 5,000 dollars per wind mill per year goes to the land owner that doesn't invest a single penny into it, which is only a small percentage of the money generated by the electricity of each wind mill per year.
aliendroid July 21st, 2007, 02:57 AM Texas is trying to position itself as one of the leading Research and Development centers for wind power in the world as well as a goal of reaching 20,000MW in 5 years.

*UofT* July 23rd, 2007, 01:16 PM Texas is trying to position itself as one of the leading Research and Development centers for wind power in the world as well as a goal of reaching 20,000MW in 5 years.

20,000 MW of just WIND!!, thats equivalent to the power generation of the three gorges dam in China
Great stuff!
We need more projects from the sole superpower of the world! and less wars.
