The title of this post describes a type of fusion energy that overcomes many of the challenges that come with conventional fusion energy systems that use neutrons to transfer thermal energy from the nuclear fusion reaction to the heat-transfer fluid.
A new breed of maverick fusioneers is aiming to solve the neutron problem. Their approach is to swap D-T fuels for readily available elements that, when fused, release energy that’s carried by charged particles, instead of neutrons.
