Reiner Stemme is already onto building one...
'swiped my great idea!

The sailplane (N151JW) burns fossil fuel today. But i'm serious about replacing it's internal combustion engine with an electric motor, batteries, and some PV on a hangar. Perhaps some PV on the ship itself is eventually in order. A typical launch now lasts a few to several minutes, but that's at ~full throttle, and then there's all the taxiing around before & after too.

If i can get a good, high launch, plus keep some battery in reserve for a "save" or two, that'd be sweet.

The Stemme S10 is quite a sailplane, and not a bad aeroplane --all considered--,
but motoring around really isn't my thing.

Electric aviation is really taking off, and i want to be a part of it.
