From Charlie Wartnaby
Ben Crystall describes a scheme “to initiate nuclear fission in… say, deuterium and tritium” (8 September, p 62).
You won’t get those to undergo fission, at least not with any energy gain.
• The scheme we mentioned starts out with fission to generate energy to trigger fusion. One reaction involves antiprotons, uranium, deuterium and tritium, but there are a number of different ideas.
