About Us

Early in 2004, Tom and Bill Lang (known throughout the industry as the Lang Brothers), grew increasingly tired of the promises to reduce gas prices and abate air pollution... 20 years from now. As a consequence, they set out on a mission to create a revolutionary, self-contained HHO system at an incredibly affordable price. After years of research & development (most challenging, the experimentation with design, output efficiency, and vehicle integration options), they developed the three Green Machines offered today.

During the winter of 2006, after equipping all their friends' vehicles with the machines (and instantly improving their gas mileage by over 40%!), the decision was made to offer ready-to-install kits to the public at-large...and was born!

Since launch, we've been met with incredible feedback from customers and enthusiasts from all over the world. We hope you enjoy your stay, your incredible savings at the pump, and look forward to hearing your feedback.

Bill Lang interviewed by the Kentucky Water Fuel Museum

Soon after the interview, we validated those high output results and launched our most powerful and popular systems to-date, the Brown's Gas Injector and our 2nd-generation HydroCharger product line.
