I recently bit the hook for one of those “manuals” with instructions on how to build and install a hydrogen generator. I then saw an article that claimed that none of these systems really work. What’s the truth about HHO generators for your car, a.k.a. “Run Your Car On Water”…

Don’t work, and, more to the point, can’t work. There’s no ‘free energy’ floating around the engine. Just think of it this way, if it did work, 1) every car would have it; 2) you’d be able to buy them at Walmart, and 3) Every car/truck-using company (taxis, FedEx, school districts, police depts, you name it) would be buying them by the thousands. Absolut scam/ripoff.
