PV and thermal can now piggyback, making the PV run more efficiently because the thermal installation helps to cool the panel to more efficient temp at peak. It depends on where you live whether you would use water, propylene glycol, or evacuated-tube for the water-heating part. SolarWorld is reported to be taking panel construction into middle schools this year. Kids and their parents are pretty excited about it. Mono-crystalline cells are still the most efficient and best proved over time. Suntech and SunPower have pretty good websites showing a range of products and installations. Beyond these three I have mentioned, I have not been impressed with other manufacturers. I own STP and SunPower.
Biofuel Production Will Continue to Grow [View article]
We haven't begun to tap the possible waste sources for ethyl production. We probably won't until the cabals can no longer produce and sell in the manner to which they have become accustomed. By then, new ways will have been invented in basements and garages. New technologies will be ready for the big guys to make monopolies out of.
