Newer versions have better results with diffuse light. Panels have dropped to only about 20% of their former price. This is by far the cheapest energy for the average person. Battery back up could be a community or local area project, completely INDEPENDANT of the system. ALL getting cheaper when everything else will get more expensive.. We are NOT a Nuclear Nation and it's not a simple or Popular move to become one. Nuclear has to be Cooled and that ADDS heat.

IF the Market won't fund it there's SOMETHING SERIOUSLY WRONG. Look no further. than that. Nev
