Is the ASW-27B still being made?

small fuel cell.

I've wondered if a gas-electric hybrid would be practical. A gas motor
powerful enough to supply half the energy of a 2000' climb at 500 fpm
would be about 20 hp, a fair sized motor. So again, maybe the solution
is a big enough Li battery to do the whole 2000', then use 4 hp motor to
recharge the battery over the next 30 minutes or so.

Apparently there was a gas-electric hybrid glider at the AERO
Friedrichshafen show, or at least a poster about one. SoaringCafe has
pictures from the show. One pic is of a diagram of an Albastar 18m
glider with internal gasoline engine driving a generator linked to a FES.

I like the idea of starting the motor before you have to commit to using
it. There is a glider with an enclosed, internal gasoline engine - the
Stemme - but it can't be started independently of propeller operation,
and the drive shaft is a difficult technical problem requiring the side
by side seating. The Albastar has a substantial engine of 65 hp, and the
use of using a generator/electric motor for power transmission to the
propeller gives it a lot of flexibility in design the Stemme did not have.

The original LS8-t did just that - engine could be started before the prop extended.

How did the exhaust get out of the glider? Was the engine fixed in
place, and only the propeller and mast went up?
