With a portfolio of six patents, DeMars is recognized for his cutting-edge developments that push the boundaries of conventional engineering and harness renewable energy sources.
Latest Patents
Among his most notable inventions is the solar thermal rocket, a modular system designed to receive and absorb solar energy and utilize it as a heat exchanger to create propulsive thrust. This ingenious design incorporates thermal energy storage modules that capture and hold solar energy through specially designed thermal energy storage elements in each module. The system features a solar energy secondary concentrator that focuses solar energy into a cavity defined by these modules.
In this system, a preheater is located adjacent to the secondary concentrator and is connected to a propellant supply and one end of the thermal energy storage modules. The propulsion process is initiated as stored propellant is directed through the preheater and the thermal energy storage modules, where it is heated to high temperatures. Finally, the heated propellant is funneled to the propulsion nozzle, where it is expelled into space, generating the necessary thrust for propulsion. This innovative approach not only emphasizes energy efficiency but also showcases the potential of solar energy in aerospace applications.
