Read the report, rather good really.

Good to see that somebody has been thinking about PO.

Didn't see anything in there about closer coupling to food prices, scalability of alternatives, flow rates, net energy or the export land model. But hydrogen powered aircraft, (from the undiscovered hydrogen reserves?) well, that's a possibility for the longer term. 2/10.

Hydrogen powered aircraft? Seeing as hydrogen has about 3% of the energy of aviation fuel by weight, i doubt it

Ok, it wasn't actually hydrogen powered, but it could be now.

Comrades!

Reads like a badly written Pravda press release -

My spies tell me the main problem was that the fuel tanks took up most of the passenger compartment area. Strictly experimental. Not forgetting you need an energy source to produce the hydrogen, conversion losses, blah blah...

Za Rondina!

Theres still quite a lot of quiet research going on with airships.
Very much in the "ship" sense of the word though.

Still, 20-30 miles an hour is 480-720 miles a day.
