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, …

Path to Megawatt Direct Drive Fusion Propulsion Has No Scientific Roadblocks

A Masters Thesis analyzed a mission to Saturn’s moon Titan using the Princeton Plasma Physics Laboratory Direct Drive Fusion system. The Direct Fusion Drive (DFD) is based on a D-3He fueled, aneutronic, thermonuclear fusion propulsion system. He considered a 2-MW-class single DFD module, which provides 8 N of constant thrust and a specific impulse of …

LPP Fusion Redesigns to Overcome Hurdles to High Yield Fusion

LPP fusion discovered the FF-2B’s prototype anode was cracked. They have used the shutdown time, necessitated by both the crack and the coronavirus, to complete the design of our new switches, and to redesign the anode. They are aiming to resume firing with these crucial new upgrades in the fall. This will allow us to …
