Abstract: A mass accelerator and power converter unit is disclosed which utilizes centrifugal force generated by rotating masses which, when rotated within their respective cylindrical housings, exert pressure on the inner curved surfaces of the housings and roll thereon. The unit includes a wheel which interconnects each of the housings and which functions as a torque wheel to provide torque amplification. A drive mechanism, including a battery-operated electric motor causes the masses to rotate in synchronism within their associated housings. A driven mechanism including a ring gear mounted on the wheel is provided to facilitate the withdrawal of energy from the unit.
