Conical Solar Panels . Even for photovoltaic (PV) panels, there’s such a thing as too much sun—when cells overheat, they become less efficient. V3Solar solved that problem with Spin Cell, a conical array that floats on magnets. An outer cone made of specialized lenses concentrates bands of sunlight on an inner cone covered with PV cells. The cells capture light energy but spin away before thermal energy can transfer.
"This option is small-scale and it is built around a reclaimed heat dispersal system from an old refrigerator (which you can get with the gas removed from your local dump). It has no pump as it is gravity fed and it requires no electricity to work. Just put it in the sun, turn on the water feed and you will get a slow but constant supply of very hot water..."
