Small nuclear fusion space and energy systems using high efficiency RF heating

•, brian wang

Princeton satellite systems and Princeton Plasma Physics Lab will work on the two projects. Phase I STTRs of $125,000 each will run for one year, at which point we have the opportunity to propose Phase II work up to $750,000.

2. Superconducting Coils for Small Nuclear Fusion Rocket Engines

The aim for the fusion drives is to get about 1 kilowatt of power per 2.2 lbs. (1 kilogram) of mass. A 10-megawatt fusion rocket would therefore weigh about 11 tons (10 metric tons). They hope to demonstrate a first nuclear fusion system in 2019 to 2020.
