Hard to tell.
It is certainly possible to get a normal car engine to run on Hydrogen. It's quite difficult to get one to run well for long - lots of issues with pre-detonation once it gets hot. Quite a few of the major car manufacturers have made prototypes and even small runs of production hydrogen-fuelled cars.
So far, so factual.
I'm a bit surprised that the setup shown in that video of just sticking a hose into the carb inlet would work, but it's plausible. The fact there's also oxygen coming out of the hose would make the complete lack of mixture regulation less important.
On the whole, I'll give the video the benefit of the doubt.
When I made my previous post I hadn't watched the video, only looked at the link, and *that* is complete rubbish. They mention that...

The reason people say this is that it's true.
Your alternator produces precisely the amount of current which is being drawn by the cars electrical system. No more, no less. The more current is being drawn, the more torque it will take to turn it, so the more fuel will be required by the engine to drive it. You can test this in various ways:
- In some cars, with the engine ticking over, you can actually perceive the revs drop briefly if you turn on the fan/aircon/electric windows.
- If you happen to have a spare alternator (or an electric motor, or an old bicycle dynamo), and feel like a bit of experimentation, you should find it very easy to turn over if it's not connected to anything, but much harder to turn over if it's connected to, say, a lamp, or even just shorted across the terminals.
- If you happen to have a science museum nearby, they almost certainly have an interactive exhibit to demonstrate this, usually involving an exercise bike.
Or you could just trust me. I'm not trying to get you to give me hundreds of dollars.
It's true that car alternators are typically *rated* for the sorts of currents they mention. That's not the same as saying that they are always producing that, just that they can (for example if your battery is a bit flat).
Just for reference, 100 amps at 12-14 volts is getting on for 2bhp. Where is that power coming from? Or more pertinently, where do they think it's going, if the alternator is producing this power all the time? 1.4kW is a reasonable size electric room heater.
I can't be arsed to run through the rest of their claims. There's certainly a few true statements in there to give it some superficial credibility. There's also some stuff that's made up.
It's certainly plausible that running on a petrol/hydrogen mix might make an engine run a bit cleaner, and that it would reduce the amount of petrol you used to travel a certain distance - of course it will, you're adding another fuel! It's claiming that you can create this extra fuel for free that is the nonsense part.
