Science and Roadmap Details for Commonwealth Fusion Systems

Here are a Lawrence Livermore and ARPA-E presentation on the science and roadmap details for Commonwealth Fusion Systems (CFS). CFS has completed and validated their 20 Tesla magnet system which is critical for massively reducing the size of a commercial Tokamak. CFS has raised $215 million and now have a staff of over 240. They …

Foundational Stronger Magnet Made by Commonwealth Fusion Systems

Commonwealth Fusion Systems and MIT’s Plasma Science and Fusion Center (PSFC) have demonstrated a magnet with a record-breaking 20 Tesla magnetic field. This is the core technology that they planned to create. They now have to mass produce it at ten times lower cost and assemble it into a net energy gain system by 2025. …

TAE Technologies Targets Commercial Nuclear Fusion by 2030

TAE has produced a stable plasma at 50,000,000°C within a compact reactor and repeated this over hundreds of testing cycles. They have had over 25,000 fully integrated fusion reactor core experiments. The experiments were optimized with machine learning from a collaboration with Google. The current goal is a commercial fusion power plant by 2030. They …

Scalable New Fusion Drive

The Helicity Drive concept is a novel magneto-inertial fusion concept designed for a fusion space propulsion system. It has promising Lawson criterion performance scaling with input geometry resulting in power output that is uniquely scalable across thrust power classes (10s kW to GW levels) at high specific power. It exploits magnetic reconnection as a fast, …

Pulsed Nuclear Fusion Pinch Propulsion

Fission/fusion hybrid and pulsed fusion propulsion have been shown to significantly reduce the trip times for space travel. The specific approach being pursued at UAH PRC is called z-pinch. Jason Cassibry has been funded by Limitless Space Institute to study and advance 100 kev nuclear pinch propulsion. They have a near-term goal of scaling to …
