Nano scale solar cells 10 times more efficient

Freki: Great find! I used to have that site bookmarked several computer crashes ago.

My guess is that this technology and others will show that the potential for energy capture is far greater than we thought. Also we are not all in the southwest. The sun also lights and heats the earth in places like Seattle as well where I doubt the solar efficiency of current systems is anywhere near the 15-20% range.
Except to judge the credibility of the author, it doesn't matter to me whether the gain from one breakthrough is 10% or 10-fold. The point is that good things are coming and government should not be paying you or mandating you to make a fifty year investment in a technology that constantly improving and obsolescing the old. Only free choices can fairly settle the questions of if, when and how to commit to an investment of that scope.

I found this website and it gives a nice little primer on nanotechnology and its application if anyone needs quick basics: http://nanobots.com/
I'm not really a science genius but this is one field that I find absolutely fascinating!
