Solar power almost reaching 24% efficency
I heard about <a href="http://news.zdnet.com/2100-9596_22-6129168.html">these</a> 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.

Off the grid does sound like a good time.
