US Patent:

20080000469, Jan 3, 2008

Filed:

Jun 5, 2006

Appl. No.:

11/446712

Inventors:

Michael Weir - Santa Ana CA, US

International Classification:

F24J 2/30

US Classification:

126643000

Abstract:

A liquid is evaporated by the sun, raised to as vapor and condensed by passing through a reservoir that condenses the liquid by heat transfer. The liquid is stored in a tank just below this reservoir of water. These tanks are connected to a turbine. Turbine is fed by condensed liquid, and the liquid is evaporated again. The system is closed and the liquid has an intermediate boiling point between ambient temperature in the sun and ambient temperature in the condensing reservoir.

Appl. No.:

11/941797

Inventors:

Michael C. Weir - Tustin CA, US
J. Scott Smith - Orange CA, US

International Classification:

F24J 2/24
F24J 2/04

US Classification:

126651, 126634, 126646

Abstract:

A solar heat collector includes a trough extending along the ground. The solar heat collector further includes a first region within the trough. The first region extends along a length of the trough. The first region is configured to absorb solar radiation and to heat a fluid flowing within the first region with thermal energy resulting from the absorbed solar radiation. The solar heat collector further includes a second region between the first region and the ground. The second region is substantially thermally insulating the first region from the ground.
