Science primer
Three paths to net energy
Every company tracked on this site falls into one of these confinement strategies. Start here if you're new — or jump straight to a company.
Magnetic confinement
Tokamaks and stellarators leverage helical magnetic fields to suspend D-T plasma at 100M+ Kelvin.
Read technical brief
Inertial confinement
NIF's 192-laser ignition shot delivered 3.15 MJ output from 2.05 MJ input — Q > 1 confirmed.
Read technical brief
Aneutronic pathways
p-B11 and D-He³ avoid neutron flux, enabling direct electrostatic conversion at high η.
