Actually, I believe (don't quote me) that hydrogen doesn't leak as badly as helium, because unlike helium it naturally snaps into a larger H2 molecule.

That being said, 80,000 cubic feet of helium is the contents of one Praxair eight-cylinder module, about 20 feet long, 8 feet wide, and 4 feet high. I may be little problem to simply resupply the system on a regular basis.

        Would be worth building test units to try out the concept. (n/t) - TB - 9/12/2007 1:38:32 PM

        Correction--it's more like one and a half 8 cylinder modules (n/t) - TB - 9/10/2007 5:53:33 PM
        
        How much does one of those modules weigh? - Un_Epi_De_Mais - 9/10/2007 6:12:24 PM
        
        I'd run the helium up a small tube. - TB - 9/11/2007 1:44:25 AM
