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.
