Aqwon, the First Hydrogen Scooter 269

Posted by CowboyNeal from the environmentally-safe-scooting dept.
An anonymous reader writes "After 10 years of research and development, Josef Zeitler has developed the first hydrogen-filled two stroke engine scooter with technical approval from the German TÜV. In case of an accident, the tank will freeze and no fire or explosion would occur. Anyone can fill-up the tank on the scooter within 3 to 4 minutes, without being in any danger. The pressure sensor will transmit the data to a computer chip, which will then accumulate and send the necessary information, regarding the proper hydrogen mixture, to the injection jet. This process of refilling is possible with a newly developed system consisting of pressure tanks and a hydrogen generator. AQWON's top speed is about 50 km/h (31 mph), the power is 2.6 kWh and the weight is minimal. This is the same as a petrol/oil two stroke scooter. There is no extra maintenance service required."

    I wonder what materials the engine is made of? Hydrogen embrittles metals so a current ICE would fail much more quickly if running on H2.

    The home fueling station is nice. Throw in a solar panel or two and now we're talking.

    But alas it's a scooter and scooters in America are like dating fat chicks: you'd like to ride it but you don't want your friends to know.

        I don't disagree with you at all. The #1 (IMHO) problem is how expensive is that fueling station? There won't be public H2 stations for some time. Honda has a home refueling pump for their natural gas powered Civic GX sedan. It costs at least three thousand dollars and takes approximately 8 hours to refuel the car. Ignoring the refueling time (which is pretty long), the cost may make it prohibitive to install a home refueling station which will in turn make it more difficult to sell H2 powered transpor

            Part of the problem is the size of hydrogen. Hydrogen doesn't just hang around as hydrogen, it forms H2 molecules for a little more chemical stability. Even though these are larger than H atoms, the molecules are still tiny enough that they seep through the walls of cast iron tanks (the way acetylene does, but worse). Anything

          The fueling station fits inside a cabinet. the multimedia presentation shows a person posing with it, where it is installed next to a washing machine. The fueling station appears to be some kind of electrolosys device connected to mains water and power (site says that solar power might have enough energy to do a good job too) and storing the hydrogen in ordinary looking gas cylinders. Refueling takes 3 to 4 minutes according to the website (click the link to "Description of innovation" on this page [aqwon.de] - they like to put their info in little popups) and provides enough fuel for a 100km range.

          The engine is oil free by virtue of design (uses some other lubrication method which they don't describe), and is very light.

      You need to have less than a 42% H2 mix with air (I can't remember if air is 21% O2 by volume or weight... you need twice as much H2 by volume, or 16 times more O2 by weight), which might be enough to fix the problem. Metal

      The Hindenburg was actually designed for helium, not hydrogen. Due to an embargo on the sale of helium to Germany at the time, they decided to try hydrogen as a substitute. Of course, it thus lacked some safety features that would otherwise have been given with that choice. Since the Hindenburg was a major PR thingy for Nazi Germany, it was decided that it would be safe anough anyway.

    We don't have large hydrogen producing plants, and we don't have a major distribution center to support it.

    i think hydrogen and electric is far better than petroleum, but hydrogen forces me to "fill up" electricity does not and it's everywhere and can be made with solar, wind, hydro, etc...

    it seems like hydrogen gets us to a more profitable proposition for companies, it's like printer cartridges and razors blades for shavers, we need to keep buying. with electricity, it's different-- we can plug in anywhere, but the gas companies do not make money off that. i think that's the other reason the auto-industry is moving away from electric cars and more towards hydrogen and hybrid, granted...batteries aren't perfect either, if the systems are not planned properly you won't be able to recycle the batteries.

    You can't drive them in enough places.

    I DON'T expect these things to drive on the interstate highways at 55+ MPH, but...

Good luck driving anything limited to 30MPH on a 40MPH road: it may be legal, but you'll probably be pulled over by an ignorant policeman (or one trying to protect you from the 30 cars tailgating and making illegal passes around you).

The police generally aren't interested unless you are seriously hurt or someone recently died. In my small city, they ticket bikes on the sidewalk but not hostile drivers.
