    Sat next to a fusion researcher once on a commuter train.

    This particular line struck me: "When oil prices go up, so does money for fusion research"

    Feels the same for sail and cargo ships.

      Sails have an immediate operational cost reduction that should add up to a future net savings. Fusion research has no immediate benefit.
