My husband has been making Hydrogen with a simple homemade device that electrolyzes water, yielding Hydrogen and Oxygen using a mere 12 volts, on demand.
He is still working on adaptations, especially for our heating system, but when the small amount of hydrogen is added to the woodstove intake, it greatly accelerates the burning, and the heat output, as well as “eating up” all the carbon and creosote deposits.
When the hydrogen is fed into the carbuerator of the roto tiller, it immediately goes from an idle to a roar, which gives us a pretty good idea of what’s possible to do with engines, with a few adjustments to the timing, etc.
The fact that hydrogen can be made on demand, using simple systems that can be made over the weekend in a garage, should be exciting to everyone,…except maybe the oil companies, and also means that no big corporations are going to be able to corner the market on readily accessible hydrogen, since large amounts do not even have to be stored. The market will be for new systems that use hydrogen, as well as adaptive technologies that can retrofit existing systems to hydrogen, so people will be able to use the cars, heating systems, etc, that they already have.
