Building a fully functional hydrogen electrolyzer that can power your home is better left to the professionals for now. More then anything, the storage of hydrogen is very dangerous.

It is feasible, however, to build a so-called Hydrogen Booster that increases the fuel efficiency of your car. Such a basic low-voltage hydrogen generator, powered by the car battery, produces hydrogen "on demand". There is no storage.

When the engine runs, the Booster produces hydrogen that is immediately mixed with gasoline and burned. Depending on the quality of the built, your car’s fuel efficiency goes up between 20-60%.

The Hydrogen Booster device can easily be homemade from readily available components from the hardware store. Total cost for the components is less then $100. -.

But you must know what you are doing. That's why it is recommendable to purchase a manual that takes you through the building process step by step.
