US Patent:

6414331, Jul 2, 2002

Filed:

Mar 27, 2000

Appl. No.:

09/535223

Inventors:

Gerald A. Smith - Scottsdale AZ 85259
Raymond A. Lewis - Boalsburg PA 16827
Steven D Howe - Los Alamos NM 87544

International Classification:

H05H 1300

US Classification:

2504931, 376127, 376156, 313 62

Abstract:

The invention provides a container for transporting antiprotons including a dewar having an evacuated cavity and a cryogenically cold wall. A plurality of thermally conductive supports are disposed in thermal connection with the cold wall and extend into the cavity. An antiproton trap is mounted on-the extending supports within the cavity. A sealable cavity access port selectively provides access to the cavity for selective introduction into and removal from the cavity of the antiprotons. The container is capable of confining and storing antiprotons while they are transported via conventional terrestrial or airborne methods to a location distant from their creation.

Appl. No.:

17/806343

Inventors:

- Scottsdale AZ, US
Steven Daniel HOWE - Phoenix AZ, US
Jack R. MILLER - Tempe AZ, US

Assignee:

ThermaSat Inc. - Scottsdale AZ

International Classification:

B64G 1/40

Abstract:

ThermaSat™ propulsion system uses water as a safe and non-explosive propellant, and which is unpressurized at liftoff. Utilizing solar thermal propulsion, the compact and efficient capacitor heats water to steam to produce high thrust and total impulse. The advanced optical system allows for the thermal capacitor to charge through solar power alone with no protruding concentrators or power draw from the main bus. Additional solar panels, body mounted to the ThermaSat, provide auxiliary heating of the thermal capacitor when not directly incident to sunlight to promote non-sun pointing operations.
