Helium

In 1923, Time magazine reported that bills introduced in Congress would conserve American helium resources as a monopoly for both war and peace purposes. Up to 500 million cubic feet of helium could be derived from natural gas wells, enough to maintain 200 airships. This amount was contrasted with probably not more than 15 cubic feet of isolated helium held before the World War. The production cost had been reduced to 7 cents per cubic foot, and helium would be preferred to airships inflated with hydrogen which could be exploded by anti-aircraft guns or engine accidents. The article also recognized that helium could be liquefied for easy storage, and that a laboratory in Toronto was producing liquid helium for military purposes.«[Ref: Time 24 Dec 1923]
