It's surprising there aren't more solar powered blimps for tours of
canyons. The forest service could use them to count big horn sheep and
other lildlife. If the weather was fair, wouldn't you like to take a
quiet ride in an airship? Maybe sneak up on a mule deer . . .

There's no question conventional PV would get a blimp going over 25
mph. Boeing's new 40% efficient PV would move an airship at 30 - 35
mph.

The first PV airship should be named the "Pronghorn."

The solar cells to power it would consume a lot of its payload.
