Producing the hydrogen could itself be rather polluting, depending on the source of energy (electric etc) used. The big problem with renewables is storage for cloudy windless days. H2 is supposed to be cheap energy storage. A Li-ion battery has a better round trip efficiency but costs 2X more than the total grid electricity it will store over its lifetime. Electrolysis isn't very efficient either but there isn't any dependency on lithium. Last year was some research on how photosynthesis splits water, in 2 stages or something. It's supposed to be more efficient than electrolysis. Bret Cahill |

I got as far as "2.5kg cannister of hydrogen". (between the legs) No thanks. A bigger problem will be someone taking it apart. Bret Cahill |

You use the bicycle dynamo to electrolyse the water to produce the Hydrogen to power the fuel cell. In fact you can produce more hydrogen on the downhills than you need for the uphills, so when you get home you can use the rest to cook your dinner. It's true, I saw it on YouTube. ;-) |

There's been many a debate about whether you could do that; Yes it can: http://www.youtube.com/watch?v=F7PNSyAfCjk -- It's a money /life balance. |
