Not knowing anything about engineering but having worked with liquid nitrogen a fair bit wouldn't the issue about leakage be cured by putting in high pressure venting valves that vented to space? Thus would keep the pressure between the two hulls constant and alway venting in one direction? (of course the inner hull would have to be made like a pressure vessel and damage to the inside could cause leaking into the inner hull). -Sue _______________________________________________ GurpsNet-L mailing list <[email protected]> http://mail.sjgames.com/mailman/listinfo/gurpsnet-l
