BrightSource and PG&E strike largest ever solar deal »
Posted By IsraGeek 5 months, 3 weeks ago in Science & TechnologyBrightSource and PG&E have agreed to terms that will make it the largest ever solar energy deal. The deal will provide 1,310 megawatts of electricity, which equals the amount necessary to power 530,000 California homes during peak hours in the summer.

At last there seems to be some large projects,concerning renewable energy.California,Texas and Israel,have large solar projects underway.In my country,the UK there are plans for the World's largest wind farm.Maybe there's hope yet!!

The tower would be surrounded by a 25,000-acre, transparent circular skirt of greenhouse panels, which would warm the air trapped underneath to about 95 degrees Fahrenheit above the ambient temperature. The cool air at the top of the 400-feet-in-diameter tower would then draw the hot air up from ground level at a speed of roughly 35 miles per hour, which in turn would drive the 32 turbines around the bottom half of the tower. The turbines provide around 200 megawatts of electricity. -

I believe I saw a model of this technology in one of this years issues of Scientific American. In that issue other types of solar power facilities were noted.

I liked the Spanish model best. It is proven, in place for a few years, and has a very low cost per KwHr. I believe that in that model the estimation is that 90 of the Spanish facilities could power all the homes in the United States. I'm writing all this from memory, but I am under the impression that the "Wind" caused by differential in thermal gradients is really an experimental model. I know that Spain is gearing up to build some more facilities based on their working concept.
What technology does our scientific community have sequestered back for a profitable day to release them?
By the way who would own the towers? Is the contract to supply electricity or sell the technology in working facilities?-

and the big question, does the electricity all go into the grid where it ends up just lowering retail energy costs and perpetuating the status quo?
Show me someone who is using solar or wind power off-grid to power their home, and I will show you someone who is gaining an intimate understanding of what it means to live within their energy budget.
Pipe the juice into the grid and I will show you someone who keeps the air conditioner at full blast and the lights on all the time because energy is cheap. -
