This is a fascintating thread in the way it reveals the thinking of many of the people on this board. From those like Kookybill, rejecting the whole idea without the slightest knowledge of the technology or it's potential, to those that oppose it on the political grounds, in that it is normally associated with 'liberal environmentalists'.
Then we have the hard headed number crunchers, that right now reject this technology because it cannot show an immediate cost return. In spite of the fact that the cost curve on this power is downward, while that of fossil fuels are ever upward. Even without the externalized costs of fossil fuels.
Then those that are cautiously interested. Those are the people that count. They are not going to pay for something that does not have a return in a reasonable time, but they are not going to reject a new technology on the basis of someone's political perceptions or luddite leanings.
In the last five years, I have seen the costs of solar drop by a factor of five, efficiencies jump from a top of 14% to 24%. In the next five, we will see an even greater increase in efficiency, and a drop of a factor of 3.
All of us have solar in our future, whether as individual installations, or installations by our utilities. The major question is whether we will manufacturing it ourselves, or buying from others.
