   Eripe, any idea how much lift would hot steam generate? Also, how hot would it   
   be?    
   About the foam idea, it is cool, but I prefer old fashioned cili   
   drical-cigarette shaped airships filled with some kind of gas. I also think   
   this exotic matter gas is more plausible :p   
   On double walled canvas, I already have those in my plans, with areas between   
   them filled with helium, but they're not to keep the vacuum, they serve more   
   like whipple shields. I believe vacuum is not worth all the problems with   
   keeping it, if I    
   understand correctly it gives just about 0,025 kg more lift than hydrogen.   
   Mr Fergerson - I would say this coronium we call today plasma, but Mendeleev   
   didn't know that. Is muonium heavier than normal hydrogen? If it would be   
   stable, and non reactive, we would have an inert gas perfect for airships!    
   PS The airship I am currently working on, is truly gigantic - 420m long and 60   
   meters wide, equipped with quite impressive weapons and with lifting   
   capability of around 1100 tons if filled with hydrogen (at least that's what I   
   calculated :p), after    
   looking at structural masses of pre war airships I think half of it would go   
   for structure mass, rest for engines, small nuclear reactor, crew areas,   
   aircrafts, cargo and at the end, weapons.
