That sizing is so desirable, because local power generation is so much more secure from severe weather events, and because the best fusion power candidate to date is the ITER Tokamak, which is HUGE, and hugely expensive.

I am optimistic....and it is this kind of human ingenuity that may save us as a species, as well as our planet Earth, and the other plant and animal species who we depend on, and in turn depend on a livable planet.
