Wasn't most of his idea a way of creating hydrogen and oxygen from water and solar panels?
McMaster calculates that 1,200 square feet of solar panels on the roof of a garage receiving 2,200 hours of sunshine a year could, with the help of an electrolysis device no bigger than a washing machine, produce enough hydrogen and oxygen to drive an MRE-powered car 200 miles a day. The oxygen would be bottled in scuba-like tanks that would snap into place under the hood. The hydrogen, more volatile and more dangerous, would be piped around the car's chassis through 180 feet of tubing, divided into 3-foot sections, each sealed off from the next by a set of valves.

is that a bit of a freudian slip?
