Many people are coming to realize that the homemade hydrogen fuel cell is a real technology, and not a scam or myth. The technology behind this gas saving device has been around for several decades, when welders first used oxyhydrogen gas for welding applications. The same technology was also employed to provide energy to operate blow torches, lamps and high-heat metallurgy ovens. It is only in recent months (thanks to high pump prices) and this technology has been adapted to provide alternative fuel to power our vehicles. Yes, hydrogen fuel cell technology exists, and the big oil companies have kept this largely under wraps to keep their huge revenues intact. And thanks to the Internet, this DIY technology have been gaining greater appeal amongst car owners.
