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...

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...

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.
new 3min movie>

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.

600m sounds great but the 1000m plan was besser

a similar tower has been already built in Seville, Spain (but it only has 165m)







the sun rays effect on the first pictures are true. when you drive through a motorway near by the plant you can see that amazing effect

^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.
