And sadly that idea is still teh retardz, as several respondents on that site point out, even withough the part about using a plastic bag to store the hydrogen in. You have to factor in the energy used to make the lye and the energy used to refine the aluminium, and then figure out how you’re disposing of the waste in an eco-friendly manner - and even the part about “recycling energy” is wrong unless there really is no market for scrap aluminium.

As for factoring the energy used to make the lye, that’s included in the price of the lye (as well as the transportation costs of getting it to the store).

I’m Norwegian. I’m at $2 per litre. That’s to say, around $8/gal with the weak dollar.

We passed $2 per litre a few weeks ago. At today’s exchange rate, we’re talking $8.18 per US gallon.
I saw an interesting take on the “run your car on water” thing, where the spark plugs were replaced with magnetrons from domestic microwave ovens that vaporized the water and pushed the piston down. Allegedly they could get the engine running. The energy to power the magnetrons… er… that came from energy generated by the car’s alternator… :smack:
To be fair, we’ve had at least one apparently sane Doper ask if an electric car’s range could be extended if it had dynamos in the wheels. :dubious: (From context, he didn’t mean regenerative braking.)
