I don’t know if stellarators have a different plan, but in a production tokamak, it’s a combination of:
- deuterium-tritium fusion, which produces lots of high-energy neutrons
- the neutrons help to keep the plasma hot, but being neutral, they escape the magnetic bottle; there is a lithium blanket around the reactor to catch them
- the neutrons that hit the lithium produce tritium for the reactor, and steam for the turbines
- dnautics 5y agoWasn't there a fusion project where the end product was a charged particle so energy could be extracted from currents generated by changes in the magnetic field as they slowed down?
- heimdall 5y agoHere's one such promising project: https://lppfusion.com/technology/fusion-energy-generator/ https://lppfusion.com/technology/fusion-energy-generator/ "Dense Plasma Focus device with aneutronic hydrogen-boron (pB11) fuel"
