Abstract
A pump uses solar energy to heat bimetals and other materials with high expansion coefficients to create movement that is coupled to pistons or impellers resulting in a fluid pumping action. The moving pistons or impellers are used to push salt water (or any fluid) through a membrane for filtration. Furthermore, the mechanical movement, powered by solar energy can be used for a variety of applications including pumps to move liquids or gases.
Claims32
A thermal pump comprising:
- a thermal expansion material structure that expands or contracts as a result of the application or removal of heat;
- a hollow chamber, an end of said structure slidably extending through a near wall of said chamber in a fluid tight manner;
- a piston within the chamber being connected to the end of said structure, said piston being slidable in said chamber in a first direction when the structure expands and substantially separating portions of said chamber before and after said piston;
- a fluid inlet for substantially filling said chamber with fluid;
- and
- a fluid outlet,
- whereby expansion of the structure causes the piston to move in the chamber in the first direction and to push fluid in the chamber toward the outlet.

A thermal pump comprising:
- a thermal expansion material structure that expands or contracts as a result of the application or removal of heat;
- a rack connected to the structure so as to move linearly as the structure expands and contracts;
- a pinion connected to the rack so as to rotate with the linear motion of the rack;
- an impeller connected to an a shaft of the pinon;
- whereby the impeller moves fluid based on the expansion and contraction.

An electrical generator comprising:
- a thermal expansion material structure that expands or contracts as a result of the application or removal of heat;
- a shaft connected to the structure so as to move linearly as the structure expands and contracts;
- and
- a gear train connected to the shaft to multiply the linear movement of the shaft;
- and
- a linear electrical generator connected to the output of the gear train and generating electricity as a result thereof.
