The technology that will save humanity

clipped from
One of oldest forms of energy used by humans -- sunlight concentrated by mirrors -- is poised to make an astonishing comeback. I believe it will be the most important form of carbon-free power in the 21st century. That's because it's the only form of clean electricity that can meet all the demanding requirements of this century
after speaking with energy experts and seeing countless presentations on all forms of clean power, I believe the one technology closest to being a silver bullet for global warming is the other solar power: solar thermal electric, which concentrates the sun's rays to heat a fluid that drives an electric generator
over the next few decades, the world needs to switch to a ground transportation system whose primary fuel is clean electricity
Solar electric thermal, also known as concentrated solar power (CSP), meets all these criteria
the Web site of CSP company Ausra illustrates, solar thermal has a long and fascinating history
