Re: [RC] hydrogen boost for improving fuel economy 50%? - Truman Prevatt

NPR had a good presentation on the state of hydrogen technology a few days ago. It turns out if you track the energy it will take more energy from oil produced electricity to produce the hydrogen produced by electrolysis than the hydrogen will produce in a fuel cell at the normal efficiency rates. That would be a step backwards.

The bond between the hydrogen and oxygen in water is very stable and it takes a significant amount of energy to break it. One source they are now looking at is to use natural gas for the source. There are twice as many hydrogen atoms per methane molecule that per water molecule and per hydrogen atom it requires less energy to produce. The by product is carbon which has other uses.

That still requires a hydrocarbon by in the short term that may be the best route but it is quite a way down the road and there is a lot of technical innovations required. For example you sure would not want to be in a car that was anywhere near an accident that involved a hydrogen based vehicle that stored the hydrogen in a pressurized tank. Can you say big boom.

In general there is no such thing as a free lunch. In addition as much as we would like to find that the "big oil" or "big auto" companies have been suppressing something that will make cars/trucks more efficient, it just ain't so.
When I was a kid there were "urban legends" about the 200 mpg carburetor that had been suppressed by "big oil".
Note that the web site has "testamonials". Testimonials only prove that you can fool some of the people all of the time.
