Microreactors Change Propane into Hydrogen 122
Roland Piquepaille writes "Microreactors have already been used for on-site reforming of fuels, such as methanol or propane, to produce hydrogen to be used in fuel cells. Now, researchers at the University of Illinois at Urbana-Champaign (UIUC) have designed very efficient ceramic microreactors to do this task. The scientists say that their microreactors are much better than other fuel reformer systems. They are now trying to reform gasoline and diesel, which are more widely distributed than propane. Does this mean that one day we'll be able to go to a gas station to refill the fuel cells powering our laptops? Probably not before a while, but read more for additional details, references and a picture of a prototype."

As such, it's a big win. Batteries are an environmental disaster, since they often need nasty heavy metals (e.g. lead or mercury), and they don't last very long. Furthermore, you waste a lot of transportation energy transporting around the mass of batteries in something that's supposed to be portable. Finally, the process of generating and distributing the electricity you need to use to recharge the batteries is itself not very efficient at all. Generation losses, transmission losses, the fact that you can't store the stuff easily and have to have it running all the time for the intermittent occasions you need to recharge your batteries, et cetera.
This way, you generate your electricity on the spot, very efficiently (hence fewer emissions). And you don't need a heavy battery containing noxious metals.
