Deletion of Liquid Air

Comment: Delete'''&nbsp; I am citing  here.&nbsp; Yes, lots of Google books snippets, but what do they say?&nbsp; I couldn't find anything to support the claim that this was a "joint American/English concern".&nbsp; Yes, there are addresses in both London and Boston, but that is not the same thing.&nbsp; With such a shaky foundation, I think the only path forward is a 100% rewrite, so that we know that every concept is verifiable and not WP:SYNTH.&nbsp; The technology was to take a steam-powered automobile and replace the steam with liquid compressed air.&nbsp; A 1953 book questions that this was ever anything more than an idea that sold stock.&nbsp; Certainly notable given the coverage then and over time, but I didn't see any mention of there being a sample in a museum.&nbsp
