A Canadian firm is showing off a hydrogen generator that they are using to increase the efficiency of existing gas and diesel engines. Current internal combustion engines are not very efficient, and the pollution caused by them is due largely to poorly burned fuel--much of it goes right out the tailpipe.
It has long been known that adding small amounts of hydrogen to the gas-air mix increases performance and lowers emissions, but the problem has been how to store hydrogen safely in the car, as well as provide a supply.
This firm has built a hydrogen generator that runs on distilled water (easy to supply) and creates hydrogen on demand, bypassing the storage problem completely. The small box is easily fitted in the engine compartment of existing cars. Independent testing shows that the device does increase efficiency (about 10%) and dramatically reduces emissions.
So one effect is to basically increase our supply of fossil fuels by 10% without any more drilling! On top of that, tailpipe emissions are so low that auto and truck pollution is virtually eliminated. The Energy Economy rolls along merrily, with big changes coming over the next five to ten years as all this new stuff reaches the marketplace.
