I want one.
I started to say, "Can I put it in a Prius?" but I just thought of a much better use.
Depending upon weight and shape constraints:
Imagine trains that use 200kw reactor to power the electric motors, rather than the diesel engines that they currently run. How much fuel does that save, and how much cheaper does rail transit become?
Imagine ships that would use them. We imagined this once before with the
N.S. Savannah, but the world was not ready. (Also, the Savannah reactor put out 74MW, so I don't know how big of a ship the Toshiba unit would power.)
And finally, semi trucks. A truck is much smaller than a train or a ship, so shape and weight would be much more of an issue - but imagine how much fuel would be saved by moving trucks off diesel.
And obviously, I'm assuming the Toshiba design is a fail-safe design that could be put in place and would run autonomously. Can't have Jim-Bob tinkering with the atom smasher in his Peterbuilt.
