Patent number: 7124507Abstract: Heat pipe wick structure wherein a stout sheet of perforated material overlays a high performance wick material such as stainless steel felt affixed to a substrate. The inventive structure provides a good flow path for working fluid while maintaining durability and structural stability independent of the structure (or lack of structure) associated with the wick material. In one described embodiment, a wick of randomly laid ˜8 micron thickness stainless steel fibers is sintered to a metal substrate and a perforated metal overlay.Type: GrantFiled: September 16, 2003Date of Patent: October 24, 2006Assignee: Sandia CorporationInventors: Charles E. Andraka, Douglas R. Adkins, James B. Moreno, K. Scott Rawlinson, Steven K. Showalter, Timothy A. Moss

Patent number: 6869330Abstract: A photonically engineered incandescence is disclosed. The emitter materials and photonic crystal structure can be chosen to modify or suppress thermal radiation above a cutoff wavelength, causing the emitter to selectively emit in the visible and near-infrared portions of the spectrum. An efficient incandescent lamp is enabled thereby. A method for fabricating a three-dimensional photonic crystal of a structural material, suitable for the incandescent emitter, is also disclosed.Type: GrantFiled: January 23, 2003Date of Patent: March 22, 2005Assignee: Sandia CorporationInventors: James M. Gee, Shawn-Yu Lin, James G. Fleming, James B. Moreno

Patent number: 6739136Abstract: A combustion system for a hybrid solar receiver comprises a pre-mixer which combines air and fuel to form an air-fuel mixture. The mixture is introduced tangentially into a cooling jacket. A burner plenum is fluidically connected to the cooling jacket such that the burner plenum and the cooling jacket are arranged in thermal contact with one another. The air-fuel mixture flows through the cooling jacket cooling the burner plenum to reduce pre-ignition of the air-fuel mixture in the burner plenum. A combustion chamber is operatively associated with and open to the burner plenum to receive the air-fuel mixture from the burner plenum. An igniter is operatively positioned in the combustion chamber to combust the air-fuel mixture, releasing heat. A recuperator is operatively associated with the burner plenum and the combustion chamber and pre-heats the air-fuel mixture in the burner plenum with heat from the combustion chamber.Type: GrantFiled: November 22, 2002Date of Patent: May 25, 2004Assignee: Midwest Research InstituteInventors: Mark S. Mehos, Kenneth M. Anselmo, James B. Moreno, Charles E. Andraka, K. Scott Rawlinson, John Corey, Mark S. Bohn

Patent number: 6583350Abstract: A method for thermophotovoltaic generation of electricity comprises heating a metallic photonic crystal to provide selective emission of radiation that is matched to the peak spectral response of a photovoltaic cell that converts the radiation to electricity. The use of a refractory metal, such as tungsten, for the photonic crystal enables high temperature operation for high radiant flux and high dielectric contrast for a full 3D photonic bandgap, preferable for efficient thermophotovoltaic energy conversion.Type: GrantFiled: April 3, 2002Date of Patent: June 24, 2003Assignee: Sandia CorporationInventors: James M.

Patent number: 5080559Abstract: An electrical pump for pumping liquid metals to high pressures in high temperature environments without the use of magnets or moving mechanical parts. The pump employs a non-porous solid electrolyte membrane, typically ceramic, specific to the liquid metal to be pumped. A DC voltage is applied across the thickness of the membrane causing ions to form and enter the membrane on the electrically positive surface, with the ions being neutralized on the opposite surface. This action provides pumping of the liquid metal from one side of the non-porous solid electrolyte membrane to the other.Type: GrantFiled: January 23, 1990Date of Patent: January 14, 1992Assignee: The United States of America as represented by the United States Department of EnergyInventors: Joseph P. Abbin, Charles E. Andraka, Laurance L. Lukens, James B. Moreno

Patent number: 4868072Abstract: A liquid metal thermal electric converter which converts heat energy to electrical energy. The design of the liquid metal thermal electric converter incorporates a unique configuration which directs the metal fluid pressure to the outside of the tube which results in the structural loads in the tube to be compressive. A liquid metal thermal electric converter refluxing boiler with series connection of tubes and a multiple cell liquid metal thermal electric converter are also provided.Type: GrantFiled: July 28, 1988Date of Patent: September 19, 1989Assignee: The United States of America as represented by the United States Department of EnergyInventors: Joseph P.
