Sergey Brin's zeppelin

Having talked hybrid blimps let's get back to airships, which are awesome. Over any planet.

So now, Pathfinder 1 seems to be about to fly. Indeed: to transport cargo or assist during humanitarian relief missions. Last Tuesday I saw a helicopter moving cargo up that narrow valley on the Boulder-Nederland road. It looked dangerous; for the 'copter, and for all us cars below it. A floating balloon could have done this, nu?

This one is 400 feet long and has a 65 ft diameter; the lifting-gas is helium in thirteen bladders. Advances in carbon and metallurgy make this feasible. It still seems expensive but I suppose Mr Brin can afford it.

I'd prefer hydrogen; recall that the Hindenberg killed by a diesel-explosion, not from the fire in the big balloon above the cabin which being a fire, duhh, burned upward.
