Are there restrictions on how close the cold and hot sides have to be to each other? I'm sure there would be some heat lost, but if you put the hot side on your roof, the cold side in your water well or in the ground and connect them by an insulated pipe, you could get a wild temperature differential with which to run your motor.
No they need only ordinary sunlight, just like other panels. THe difference is in the choice of materials comprising the panels, and their Geometry. Solar is now competetive with all forms of energy, and with bakns of ultracaps or storage-cells, makes the GRID obsolete.
