More Like The H-Drifter.

Remember ZipZaps? Well this is not that. It is a small car, but the zip is lacking. The explaination is what makes this interesting. The toy is meant as a demonstration of hydrogen fuel cell technology. That's right you generate your own hydrogen and pump it in at a tiny filling station. Watching solar electrolosis: neat at first, but then you get distracted by grass growing. Still I spose its on par with any of those at home science experiments I did when I was a kid. Growing crystals, baking soda and vinegar, sucking eggs. The article basically comes to the conclusion that I've been asking about for a while now. Why are we using electricity to make hydrogen to put into cars? Lets just make better batteries and skip the middleman.

Nevertheless, the H-racer does provide a powerful lesson about the feasibility of a hydrogen fuel economy. And that lesson is that, as demonstrated, it is a disappointing power delivery system. As you patiently wait ten minutes for the fueling station to extract enough energy from the solar panel to create enough hydrogen to eventually run the car, you can’t help wondering why you didn’t just strap the solar panel and a battery to the car and be done with it? Instead of a miracle fuel, the tank full of hydrogen is just acting as a complicated battery with plenty of built-in inefficiency and extraordinarily low capacity.
