There is absolutely no problem in building an electric 200kt 4-seat tourer - the 350HP brushless (3-phase) DC motor would weigh no more than 50kg.
It's the batteries..........
and (if they existed) where to charge them from. You would need more than a 13 amp socket
With a massive breakthrough in battery technology (of the order of 10 times better than present best) and nuclear fusion to generate the electricity, we have a good proposal
