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.

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...

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???

A 1000m solar tower will happen.

Expect one after the 500m if its sucsessfull.

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??

Oh Well!

I was looking forward to 1000m.

Burj Dubai will break 800m and that's not all that bad.

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.

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!!!!

Cool thanks for the clarification. So, maybe in another year to year n a half, this one should be u/c.

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

Have heard about this. It could be the first structure to pass the 1 kilometer border if they didn't scale it down!

Anyone have a link?

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 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.

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.

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!!!
