Default Can Aircraft Be Far Behind?

The batteries weigh 900 lb., and put out 75 HP for an hour. You wouldn't
get too far on that in a C150.


you would save a noticeable amount of weight from not needing to carry
fuel (avgas is something like 6lbs per galon, so that would be approx
300lbs "offset" (not saved, but shifted to battery cell weight)
also, no oil (so thats a few more pounds)
and electric motors are fairly light compared to internal combustion
blocks


it would seem that powered gliders would benefit the most from this
tech because of their larger wingspan, mostly daylight operations (so
solar power), and they could probably recharge a little by spinning a
turbine when using airbrakes or something
(not a glider student and not an electircal engineer, so not really
sure about how useful this would actually be)
