Gliders flying at night? Given that some have difficulty in daylight I
can't see that idea catching on :-)

1) Interesting "winglets". I wonder if these are aeronautically
sound
or were they used simply because they look good.

I bet the interference drag from those tip loops would more than
outweigh
any possible benefit.

3) I can't see that tiny engine-generator unit coming remotely close to
running the electric motor at night or under cloud. I notice that
there's
no fuel tank or electric storage system.

4) One of the drawings shows "transparent photocells" on top of the
cabin.
Transparent photocells are impossible because by definition all photons
will pass straight through. Translucent or band-pass photocells may be
possible but that's not what was described.
