 In 2002, the firm Hydrogen Technology Applications patented an electrolyser design and trademarked the term "Aquygen" to refer to the hydrogen oxygen gas mixture produced by the device.Originally developed as an alternative to oxyacetylene welding, the company claimed to be able to run a vehicle exclusively on water, via the production of "Aquygen", and invoked an unproven state of matter called "magnegases" and a discredited theory about magnecules to explain their results.Company founder Dennis Klein claimed to be in negotiations with a major US auto manufacturer and that the US government wanted to produce Hummers that used his technology.
