As the title says, I’m interested in this community’s perceptions on nuclear energy.

    If fusion were ever to be feasible, would it also need to used mined uranium, or are there other fuel sources?

      Current fusion (thermonuclear bombs) require a fission bomb trigger to start fusion in a lithium deuteride body, but reactors - absolutely not.

      Fusion reactors do one of the following:

      • use magnetic fields and electrical current to contain + heat a ring tritium (hydrogen isotope) plasma to extreme temperatures
      • use a laser pulse to compress + heat a capsule of tritium to extreme temperatures
      • use a magnetic field and electrical current to collide two rings of helion (helium isotope) plasma at extreme velocities

      Short version: fusion needs fission only in warfare.
