The prospectus makes for fun reading. They note they are ready to release automobiles with both Liquid Air propulsion as well as steam propulsion (for areas where Liquid Air isn't yet available) in Juky of 1900. Another part of the brochure notes "under our system of manufacturing Liquid Air, we manufacture Pure Liquid Oxygen". A number of the images are obviously doctored, the company compares the endless market to those of Westinhouse Air Brake, Merganthaler Linotype Company, and McKay's Shoe-Lasting Machinery.
Wikipedia notes the company went into receivership in 1901. The Virtual Steam Car Museum online is skeptical Liquid Air was ever feasible given an estimated efficiency of about 4%. One group's attempt to drum up some money in the new craze of automobiles in American.
