Hi Clean and Cheap Energy,
I have been investing in PV for over five years, and now have an 800 watt system at the cost of $4000, or $5 per watt. All my house lighting is powered by this battery backed system, that uses a 12v charger back-up battery charger instead of a an invertor. Some cells are silicon slices, and some are monocrystiline panels, but they really work, and operate at no-cost.
We all know that PV is not very efficient, less than 10% efficienecy from the "given", one watt per square meter of solar energy, but they are dependable and long lived, especialy if they a grid-tied.
Deep cell-batteries are expensive and have a limitied life, but are affordable for "cash-limitied" investors. Bloom Boxes are coming, and they can run off of PV generated hydrogen. www.nrel.gov have some interested integrated PV/wind system making hydrogen gas for off-the- AE production operation.
When we talk about "cheap" energy, it is all relative to what the grid is charging. Because of a utility merger, in our area, Otero County, New Mexico.
I am a retiring "engineer" was is impatient about the lack of committment to Clean and Cheap Energy. Thank God, we have people like Steven Chu, who are smart enough to make things happen.
An all electric car went on the the market today, fro under $30K, so lets' get this show on the road. We are looking at 30% grid growth by 2030, so we better get hopping for "new long-term job growth".
Pickens makes it plain that we "just are not getting serious" about AE industries (like the rest of the world).
What will it take for us to gear up our industries like we did in WW2?
