Abstract
Abstract An electro-dynamic power converter for transforming the kinetic energy of a moving stream of water into rotary power is disclosed. A turbine rotor is received within a power flow housing and has turbine blades for imparting a mechanical turning force on the rotor in response to fluid flow through the power flow housing. An impulse chamber having sidewall portions defining a diverging passage is coupled to the power flow housing inlet port. Electrodes are received within the impulse chamber for conducting an electrical discharge within the impulse chamber. When an electrical arc is conducted between the electrodes, the water flowing through the impulse chamber into the power flow chamber is vaporized, and a shock wave is propagated through the impulse chamber. The shock wave is reacted in part by the mass of the water in the impulse chamber, and by baffle plates. The shock waves and the expanding water vapor provide increased torque output.
