Reality check: The existing electric plane designs barely keep themselves
aloft and have a niche as orbiting reflectors but not as cargo carriers.
With chemistry one can start with most anything and get anything else,
within reason, but not at reasonable cost. Fir high performance aircraft,

There something called magneto-hydrodynamic propulsion for submarines.
Is that similiar to this NERVA/jet engine

No, that's for highway speeds.
The next idea is the battery swap, but who will trust that the

That's about 14 kW. Do that for three hours and you have 42 kWH.
Right. 14 kWh per hour. 60 mph = 100 kph. (Okay, 97 kph to be exact.)
