oooh, this should spark some innovation.
63%... I think we can do better, much better.

63% seems okay for harvesting free solar energy. I imagine this will go up when they start to be used.
A better metric would be: how long until they pay themselves off
good point.
once others steal the ideas, the price will come down.
