Abstract
Nuclear fusion powers the sun, and indirectly the earth via solar, hydro and fossil fuels. Clean power generation from fusion reactors has been 40 years in the future for my entire life. Two methods for the fusion process - inertial or magnetic confinement - have now achieved "breakeven" - more energy out than in. But that energy is in the form of fast neutrons, whereas a power station should produce electricity. In this talk, I will discuss how to build a "box" to contain the reactor, to convert neutron energy into electricity and to generate tritium fuel along the way. There will be nuclear physics, magnetohydrodynamics, quantum mechanics, condensed matter physics, self-healing crystals and cake.
Refreshments
Meet at 16.30 outside the lecture theatre for tea and cakes prior to the talk.
