I couldn’t comment on DC being better for ships and locomotives. (but a wood burning, triple expansion steam engine powered, paddle wheel river boat works for me). I am just making the board aware that 60 hz AC will be the flavor of power used in US in the forseeable future for local transmission and distribution. DC has some advantages for very high voltage long distance transmission. But if FF becomes a reality, long range transmission would be un-necessary very quickly.
Even I concede that there would be no reason to site plants outside the region the power is needed in. They just need to be outside of town and out of sight of the NIMBY’s.
