Browsing Tube, as you do, found this...

Good to see a professional at work

, in his kitchen?

So I got looking and found this..

I just thought it was interesting, anyone tried anything similar?

It would have been even better if Borat had taken his side panel and air filter out before starting his video.

It's unmitigated b0llocks. Science fail in virtually every sentence.

+1 Utter tosh.

So is the tube vid just joke/illusion? His mate somewhere, Stavros, with a kill switch on a wire and the fuel fed from elsewhere? It did seem to rev well for a few bubbles of gas.

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...

There are many different websites and Critics online that often argue that Hydrogen on Demand Technology does not work. They say in order for this technology to work, you would have to break the first law of thermodynamics, citing that you can't get something from nothing.

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.

It was all going so well for him until he turned the throttle, revealing snappy response and the increased revs - mystifies me how the throttle is connected to the HHO generator to tell it to produce more hydrogen?? It's all well and good sticking the hose in the inlet and getting it to tick over on the gases, but as soon as he opened the throttle it should have just run out of puff and stalled as the mixture would have been ridiculously weak! All opening the throttle is going to do is let more air in!! At best, an HHO generator the size of that he is using will only produce about 1litre of hydrogen gas a minute, which is effectively nothing in terms of fuel density, or energy! I'm afraid it's all bowlocks.
