Mount such a drive on a frictionless skate board in a vacuum. Turn it on and the device will accelerate while using a constant amount of power. When it reaches a high enough speed, lower a wheel connected to a generator. At some speed, the generator output will equal the constant power the drive is using. At any higher speeds, it is making "free" power. Keith ------------------------------------------------------------------------------------------------- Or maybe at higher speeds, your skateboard will decelerate until you reach the power in = power out speed. The "free" power is just the excess kinetic energy you developed before the generator was engaged. Robert
