  6. Don't think that's accurate by SimianOverlord · · Score: 3, Interesting · on Fuel Cell Powered Scooter

    The sodium borate is being used somewhat like an enzyme, in that it facilitates a reaction but remains ultimately unchanged. It can be reconverted back into sodium borohydrate. So a fuel cell of this type doesn't need any extra sodium borate once created. And thankfully doesn't make any sodium hydroxide, which is a pretty nasty chemical.

    See here.

    Anyway, fuel cells will make cities better places by removing gasoline fumes, but when you consider they have to use conventional power sources ie nuclear/coal/natural gas/oil power to ultimately charge, their environmental credentials don't look so great. Still, it could make a great difference to the pleasantness of city life; I've noticed an afternoon in London gives me black bogies all day.

  7. Hydrogen from Sodium Borohydrate.... Patents ?. by Gopal.V · · Score: 4, Interesting · on Fuel Cell Powered Scooter
    Would this be affected by the patent on catalysed reaction to produce hydrogen (using a sodium borohydrate solution ?).

    The fuel source itself is not very newsworthy. It was around in early 2000 as well (named the Millenium Cell. Of course, it does not explode unlike the CNG powered ones. Recently (1-2 month) back we had a blaze up near our office when a Truck rear-ended a gas powered car (it's very common these days) and the gas tank ruptured, exploded and threw the car's rear door about 3 feet into truck's engine (breaking through 1/2 inch metal sheet). Thankfully only the driver was in the car and he was saved by the rear seat from the explosion.

    This is not a viable alternative. But, Hey .. it was done because some guy said "We CAN". And that's reason enough :)
