Sounds bogus to me; the infernal internal combustion engines in our cars need fuel (hydrocarbons) to produce power, and water, although composed of hydrogen & oxygen, isn't fuel! ..... there has been some success introducing small amounts of water into the combustion phase of very large, slow turning diesel engines (producing steam, not "burning" it) but our little automotive engines have never shown that capability.... I'll bet there's more going on in the Taurus than meets the eye...
