Actually, aircraft (specifically motor gliders) are far ahead!

It might take a little while before the power efficiency of batteries
equals the needs of a useful airplane...

Most GA airplanes aren't necessarily "useful." They're just flown around
for the hell of it. Imagine if you could log an hour of training or
practice or do a quick photo sortie without burning fuel.

I'm just disappointed that the Big Ass Rubber Band (tm) technology never got
past the balsa aicraft stage. Must be a big oil conspiracy.
