re: Sounds promising... not to moi
The area density power for solar even at higher than available efficiencies is LOW. Lots of land area needed. Blow away much of a state in the Southwest to meet national needs. Instead, a rational society would set aside a Natl Guard & Robotics protected square mile in the desert and pile up the non-recycled nuclear waste for the next 2 centuries.
Solar is fine to reduce coal burning growth but then give up any idea of electric powered transportation unless we go nuclear. Bigtime.
