Venture Capital Still Likes Solar

From the WSJ Venture Capital Still Likes Solar.

There are a couple of different strategies to lower solar cost.

1. Increasing the efficiency of the solar cells.
2. Reducing the cost of solar cells. Using less silicon or a different material.
3. Concentrating the sun light on the solar cells as a way to increase the overall system efficiency.

Infinia Corp. is going the concentration route with what I would call a Heat Pump, but they are calling a Stirling generators. Basically using solar energy to heat up a liquid/gas, that then drives a piston that can drive a generator. I prefer Photoelectric due to less moving parts on a theoretical basis due to less moving parts, but if it works, why not!
