The Future may be very interesting and at current rate of change in battery tech, may be closer perhaps than we envisage!

Though some of you might be interested if you haven’t seen this proposal yet.

I agree; the future is closer than we tend to think. :-) We use things every day that were science fantasy (not just fiction) when I was in high school. I'm pretty confident that by the time my RV-7 rotary flies, I'll be able to put an affordable electric motor & batteries on at least an ultralite style a/c as an 'after supper' toy.
