Soooo...no need for electric car charging stations?
To operate an on-board generation system, an electric vehicle could adapt this technology. It is only necessary to have a point source of heat. A very small molten-salt nuclear reactor can supply that point source of heat, and the heat can be used to operate a Stirling cycle hot-air motor which drives a generator unit, feeding power to the drive wheels.
Only trouble is, there is no throttle on the nuclear reactor, it generates this heat continuously. While not in use, the heat would have to be vented in some way, perhaps for home heating, or a similar fixed-position Stirling cycle motor driving a generator through a connector coupling while the vehicle is not in transit. It is the problem of too much and in the wrong place.
Clever minds can go to work on this problem.
