Abstract

A solar powered engine and tracking system comprises a piston, a cylinder turning a shaft driving an electrical generator and a solar concentrator comprising mirrors each reflecting Sun light on a common focal point on the end of the cylinder for heating a flash boiler on it. Preheated water is injected into the boiler by a pump powered by the drive shaft. A starter motor rotates the drive shaft until piston movement is self sustaining. The device is enclosed in a solar energy collector panel to maintain water temperature wtih a minimum of external heating. Sensor-controlled motors track the relative movement of the Sun and Earth and continually position the collector for maximum solar energy concentration.
