I love seeing things like this:
A company in Washington State claims that by using automotive industry suppliers to mass produce parts a solar concentrator and Stirling engine can achieve high efficiency and low cost electric power generation."The difference between our economy and a green economy is not as substantial as people think."
I hope he's right. Our great-grandparents could not have envisioned personal computers or the Internet, and we probably can't envision the innovations smart people will come up with even in the next decade.
