wanfuse123 writes: The combination of recent super capacitor battery discoveries previously covered by Slashdot combined with Percival Zhang's cheap Hydrogen production method, I predict will render the gasoline engine obsolete within 10 years. Percival Zhang not only shows a cheap way of producing Hydrogen from biomass, but also demonstrates that using carbohydrates to store the Hydrogen until the car releases the Hydrogen safely and efficiently. "Hydrogen gas – a small, energetic molecule that reacts with many materials – is difficult to store and to transport. His solution is to produce reactive carbohydrates – that is, carbon-hydrogen-oxygen molecules – at a biorefinery using local biomass resources. That product, a carbohydrate, would be the hydrogen carrier. No complex infrastructure required. You could buy it from a grocery store or dry goods outlet." His discoveries conform with the Department of Energy 2017 Ultimate Solutions Criteria of 300-500 miles on a single tank. Percival Zhang has made a huge contribution to the production of hydrogen from biomass. The name Percival comes from the old French. Invented by a medieval poet in the 12th century for one of King Arthur’s nights whose virtue was so great that he alone could retrieve the elusive Holy Grail.
