What is going on with these things? There are many people around the internet, and local now, that claim these hydrogen/electrolysis boosters do increase your fuel efficiency (mpg) by at least 30 percent. I've seen these devices working first hand, and for some reason they do seem to be increasing fuel economy and power. How could these boosters be working to increase fuel economy and power (assuming they do actually work)? Could they be increasing burn efficiency of gasoline by igniting before the hydrocarbons?
