Comment by Hayder Jalil on January 26, 2012 at 9:43am Video: World’s tallest building could be a 24/7 Australian solar chimney.
Bad news for Dubai’s 829-meter high Burj Khalifa. It might lose its distinction as the world’s tallest building, if a bunch of hot air takes root as planned in Australia. Perth-based Hyperion Energy wants to build a kilometer-high “solar chimney” in the Western Australian outback, in partnership with German engineering firm Shlalch Bergermann. (Okay, so Saudi Prince Alwaleed bin Talal also has a 1,000 meter edifice in mind, as SmartPlanet’s Tuan C. Nguyen wrote in August. I guess what goes up keeps going up!). The monumental scheme rests on the principle that hot air rises. A ground level canopy less than a millimeter thin and covering 3600 hectares would heat air that would escape up the .62-mile high shoot. Along the way, it would drive 32 turbines, with a total capacity of 200 megawatts - roughly the same as is often proposed for small modular nuclear reactors. for more info you can visit below web site /

Comment by Rodney Smith on October 5, 2011 at 4:01am Evacuated tubes manufactured in china seem to be the best way of using solar energy. I have six square meters collection area which gives between 1,5 annd 5 KW depending on the weather conditions.
Most of the energy is for domestic hot water and the surplus is dumped to radiators.
If the start point for central heating is 30 degrees centigrade instead of say 12 degrees ,this represents quite a good saving in input power.
The system cost £2000 self build and it is definitely worth it.

Comment by Paul Passarelli on July 27, 2011 at 7:25am @ Mohammed,
A Solar & Coal hybrid... hmmm... Certainly. However, the problems would be entirely regulatory.
First you'd want to start with a CSP system that is suitable for the desired project. Then once that part is set, the addition of a small coal boiler would allow the solar plant to generate "prompt" energy when the sun shines with insignificant coal consumption, and "on demand" power for the other times (cloudy days) and especially at night.
As a solar guy I would size the plant based on sunshine 1st and fuel 2nd. Of course the other way is to construct a coal fired plant then add solar capacity sufficient to supply the parasitic loads of the plant. This is a valid option, but emotionally, I'd have a hard time calling it a solar hybrid.
Not that I would object selling my CSP gensets to any and all coal fired plants that'd like to "diversify" into alternative energy ;^) {If you know what I mean}
