Hey all,

I dont really want to get to much into this discussion except to say that; Yes Hydrogen burns and can be used as fuel however it takes more electricity to convert water into hydrogen than it produces, therefor isn't a viable fuel.

I'm not sure if this is because our current technology isnt efficient enough or if its a scientific fact that you cant do it efficiently.

However, if you were to convert the water at home, then use it in the car it COULD work out cheaper than paying for petrol, but then you run into the problem of transporting it.

If you really have any queries you should call triple J on Thursdays and talk to Dr Karl as the Hydrogen Fuel Cell question is quite a regular one.
