Hindenburg/Hydrogen: Thanks, Dan. Thanks for the detailed information about the Hindenburg, and for the informed discussion about the possibility of generating hydrogen from ambient water. Looks like my memory is not so good, but not entirely wrong. - guy6
I was not suggesting sucking water out of the atmosphere. My first paragraph elluded to water for ballast. 365 days later when you want to land and you want to compensate for the Helium you've lost during your stay in the stratosphere it would be a nice touch to have some H2 on hand.
