How is a brushless motor going to rotate with just a DC power supply? +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ We are like tenant farmers chopping down the fence around our house for fuel when we should be using Nature's inexhaustible sources of energy -- sun, wind and tide. ... I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that. -Thomas Edison, inventor (1847-1931)
