A Compact Broadband Static Fourier Transform Spectrometer

Most Fourier Transform FT spectrometers use 2D optical plane interferometry and produce an interferogram by either a moving mirror (Michelson) or a static curved mirror (Sagnac). However, these spectrometers only use 50% of incoming light and rest is redirected towards the source. We present a new 3D optical layout for a modified Sagnac interferometer using all incoming light.

Displaced Inertia Distributed Acceleration

Breakthrough Propulsion Program -Asymmetrical thrust demonstrated

NASA seeks to find an inertia style thruster (Breakthrough Propulsion Program BPP, 1996 – 2002). The proof of concept in the attached drawings depicts a simple mechanism, self contained, that produces an asymmetrical thrust that results in a velocity of 30 ft/sec (about 24 mph) in this example.

Microwave Reactor

We have developed a microwave reactor.

Our proposal is a multi-emitter microwave device that captures gases, CO2 from engines, and reforms them into calcium carbonates, And The Calcium Carbonate is of high value for gas and oil drilling. Since it saves money by preventing drilling fluids from being lost in cracks, when trepanning.

CamSat

A satellite is a celestial body orbiting along a certain trajectory (orbit) around another object in outer space under the influence of gravity. Small satellites are a type of artificial Earth satellites with low weight and size. Satellites with a mass of less than 0.5– 1 ton are usually considered small.
