Sounds like crap to me

For a start, electrolysis is slow, as mentioned, it produces hydrogena nd oxygen from water rather than nitrogen (which is inert).

It doesnt mention whether he is piping the oxygen side or the hydrogen side to the intake. Either way I can't see it working without it being a complete conversion to the engine, engine management and fuel/induction system.

Now, the BEST thing I have seen in a LONG time is a bloke up in Scotland, (it was on a tv program a while back). He converted some little car to hydrogen power, which is all well and good, perfectly achievable.

But as he lived up on one of the Scotish Isles, he put a wind tubine up on his land, and used this turbine generator to perform electrolysis, generating the hydrogen required for his car! Which was properly free fuel, totally green etc......natural energy used to generate it, and when burned, it just generates water, nil carbon emissions.

Fairplay to the guy for that - and I'm not a fan of anything "green" at all!
