Largest Solar power plant in Arizona..

http://www.inhabitat.com/2008/02/25/world%e2%80%99s-largest-solar-power-plant-coming-to-arizona-in-2011/
"the enormous solar plant called Solana will power up to 70,000 homes, and will be the first example in the country of a major utility getting the majority of its energy from solar. The 1900 acre plant will be completed by 2011 – IF AND ONLY IF Congress renews the clean energy tax credit that’s set to expire at the end of 2008."

Solar energy tapped without Solar panels

Solar energy tapped without Solar panel..
http://www.techcrunch.com/2008/02/11/clean-energy-startup-infinia-raises-50-million-to-crank-up-manufacturing/

"Using its Stirling engine technology, Inifnia thinks it can eventually produce electricity 20 to 30 percent cheaper than today’s existing solar panels. And in times of peak energy demand—on a hot summer day, for instance—it could even be competitive with electricity from gas-powered or coal-fired plants. Renewable energy isn’t going to replace fossil-fuel technologies off the bat, but if they make economic sense for utilities to deploy in a hybrid grid, they will become more cost-competitive over time. With this round, there is $50 million on the table that says Infinia will be one of the companies that makes renewable energy more affordable."

Can't disagree on the economy aspect!!

Energy is everywhere. In the sun, wind, and now rain.

"Energy is everywhere. In the sun, wind, and now rain.

Researchers have developed a technique that harvests energy from rain showers and converts it into electricity. The technology could work in industrial air conditioning systems, where water condenses and drops like rain."

http://dsc.discovery.com/news/2008/02/07/raindrops-energy.html

"The method relies on a plastic called PVDF (for polyvinylidene difluoride), which is used in a range of products from pipes, films, and wire insulators to high-end paints for metal. PVDF has the unusual property of piezoelectricity, which means it can produce a charge when it's mechanically deformed.

Guigon and his team embedded electrodes into a thin membrane of PVDF, just 25 micrometers thick (it takes 1,000 micrometers to make one millimeter). Then they bombarded the sheet with drops of water varying in diameter from 1 to 5 mm."

Human energy generation..

Not spiritual energy :), Energy from your legs while you walk!.

Solar power, full use

I am watching the shuttle docking to the ISS and the bright Orange glow of the solar panels on the ISS. Probably one day we should be able to make this work in ground too..
