ABSTRACT:
An apparatus which uses friction to generate heat for heating liquids. The apparatus includes a cylindrical rotor disk housed inside a close-fitting housing structure. The rotor disk is connected to the shaft of a motor which turns the rotor disk at high revolutions inside the rotor chamber of the housing structure. The rotor disk has a plurality of curved, outward radiating, closed-end passageways formed therein. During operation, liquid flows into the housing structure via an inlet port which fills the rotor chamber of the housing structure and the curved passageways in the rotor disk. When the rotor disk is rotated at high speeds, the liquid located inside the curved passageways is pulled outward by centrifugal forces which creates a vacuum therein. When the vacuum becomes sufficient, the liquid "cracks" or boils at a low temperature. The resulting vapor formed inside the curved passageway suddenly forces the liquid remaining inside the curved passageway outward and exit at relatively high speed. The exiting liquid pushes against the leading inside surface of the curved passageway to help turn the rotor disk thereby increasing the efficiency of the apparatus. As the vapor in the curved passageway cools, it condenses to create a vacuum therein which draws the liquid back therein. When the liquid in the housing structure has reach a desired temperature, the vapor and the liquid is then allowed to exit via outlet ports.
