Renaissance Fusion
🇫🇷 Grenoble, FR · Founded 2020 · Active
Renaissance Fusion is a company in Grenoble, France, designing stellarators, fusion machines that confine plasma with twisted external magnetic coils. Instead of winding individual coils, it coats large cylinders directly with high-temperature superconducting films and then engraves the coil pattern by laser, and it assembles the stellarator field from a ring of these patterned cylinders. The cylinders are to be coated with flowing liquid metal, which it says will shield against neutrons and carry away heat. The company says it is industrialising each of these technologies separately on the way to a power plant.

Terms
- Stellarator
- Confinement produced by external coils twisted into complex three-dimensional shapes, so no net current has to be driven through the plasma. That removes the disruptions a tokamak's plasma current can cause and allows continuous operation, at the price of coils that are far harder to design and build.
- Deuterium–tritium
- Lowest ignition threshold; 80% of energy in 14.1 MeV neutrons. The reference fuel for every near-term net-gain claim.
