I heard about
these this spring from a friend who works with windmills. Essentially, it's just a Stirling engine running on the sun's rays, but these happen to be quite small, and clearly less monstrous than windmills (even though I love windmills).
Infinia is targeting 3 kilowatts systems, an average residential home, and can be used anywhere the sun shines. I want to be off the grid... wait, I want to stop paying rent first.
