Gasoline can be safely converted into a Vapor that's 100 parts of Air to 1 part of Fuel.With this, even the largest SUV could easily get 50+ MPG, & emit a fraction of the Emissions of an EPA mandated 14.7/1 Air/Fuel Ratio.Do a search on Tom Ogle,& http://energy21.freeservers.com/bookrep.html & check out the bottom of the Page.But, when a Vehicle Emissions Test is done,Oxygen exhaust sensors must detect enough polluting exhaust emissions that would inicate that fuel is being consumed at 14.7/1.That's the Law.Thus, it is entirely possible to fail an Emissions Inspection for not generating enough pollution!My Photo is of a Vaporizer, ignited to prove that it works.It's not for sale, since it's illegal!Big Oil & Big Government have outlawed it,and Obama won't change it.If we are ever to markedly decrease the use of Oil, and reduce vehicle emissions that contribute to global warming, this has got to change!
