The new Electric Cessna 172

One would think the research money for big electrical sources would be better spent on fuel cells (not that they don't have problems of their own like generating a lot of heat) than on batteries and capacitors. Oh no! We can't have any machinery in a vehicle that generates lots of heat! I'm as discouraged about fuel cells as you are about batteries. This fuel cell plane is distinctly unimpressive, I haven't heard any recent news on it. http://www.popularmechanics.com/tech...n/news/4257294 There's also not much recent news on the few fuel cell cars that Honda was or is leasing in California. Plain Hydrogen has some real problems as a mass fuel. I don't see fuel cells becoming popular until they perfect reformers, which are the "Holy Grail" technology that will allow them to use liquid fuels. So far, reformers work mostly only in the lab, and are very sensitive to fuel impurities. |

Problem is current fuel cells generate a LOT of heat and there are limits to how much you can easily dump, especially for a car at a stop light. I don't see fuel cells as becoming a mass anything until they run on something the average idiot can handle at least as safely as gasoline, and hydrogen has far too many issues to qualify. |
