Abstract:

A solar steam generator has a hollow steam rotor mounted for rotation in a closed compartment located within a larger housing. The rotor is made of heat conductive material and is supplied with water or other working fluid through an inlet at its central hub. A plurality of steam jet outlets are located around the periphery of the rotor; and they are oriented to cause the rotor to spin as the water or working fluid inside is heated to a boiling temperature. To cause the fluid in the rotor to boil, Fresnel lenses, located in an open end of the housing, focus heat from the sun onto the rotor and the chamber in which it is located. Steam and fluid which exit from the nozzles is recovered in the sealed chamber and is returned through a condenser-reservoir, from which it is supplied back to the water inlet of the rotor.
