NEREUS MK1 is a preheat-breeder cycle semi-destroyable fusion drive. It runs on only water, and can function in reactor-only mode. Water is used as fuel as well as reaction mass - exhaust is composed of superheated steam and fusion waste products.

    Very detailed, and as others said, amazing use of the control panel with multiple modes. Excellent way to explore and learn from. +1

    nvm, FRME, screws up the nozzle seal. some other indestructible insulating material could work

    replace ttan with rsss, crmc with dmnd, and insl with frme and it can run with ambient heat on
