Eeeew eeew eew!
I love that creativity!

Here's another:

Apart from the fact that these are 'self powered' and don't need a
whinch or tow they are popular because of their silence.
Swiss and Germans get very cantankerous about noise (from piston
engines) in their neighbourhoods.
You can get about 3 climbs to 1200m or so out of a charge. I immagine
the batteries are better now.
AFAIKT batteries are now comfortably offering 200kW.Hours per ton,
while electric motors are lighter than piston engines and more like
turbo-props in power/weight ration. Hence A passenger aircraft
capable of flights of 200 miles (320km) with reserves is a possibility.

years and now models up to 1:2 scale are capable of being electrically
powered.
This does not apply to just low drag glider type models but to scale
jets capable of vertical up climbs
Nice to see the full size world catching up..

Batteries with energy densities of around 90Watt.Hours/kg certainly
make these electric sailplanes viable as do the 200Watt.Hr/Kg LiPo
batteries. A battery known as a LiFePO4 (Lithium Iron Phosphate) is
looking very good from a life and price point of view and if the
boffins can get it working of sodiun to make NaFePO4 batteries then
all the raw materials will be even cheaper.
Potentially on the horizon are batteries with densities as high as
800Watt.Hours/Kg (LiLi batteries) and these surely will make light
recreational electric planes very attractive. Even the 160Watt.Hour
from LiFePO4 probably would make an interesing little two seater
though it would still tend to be sailplane like with efficient high
aspect ratio and therefore expensive wings.
The military must be getting interested. An electric aircraft would
have a very small thermal signature, a usefull feature of a stealthy
spy aircraft or drone.

Once they go solar these planes could be travel over seas.
