That last is the big problem. If we want REAL weight savings we have to
increase the volume. That's called a blimp, and to get useful weight
savings it must be BIG BIG BIG. Now we have a Bonanza that weighs 100
pounds ... but it's 400 feet long and 100 feet across. And NOW we have
to add back in the parasitic drag that all this increased wetted area
generates, and now we are down to 35 knots TAS at full power.

Since it is a glider, it does save the weight of fuel.
