That was rather my supposition. I would expect a usable working hydrogen generator to be unaffordable to ordinary mortals. Cost has always been the Achilles heel of Hg technology.teActually a box of s

Plenty of youtube vids that suggest otherwise. People making homemade wet cell versions out of jars & st.
You can make something that makes hydrogen no problem. It's just two electrodes in some water. t.The amount of hydrogen you make in a jam jar hooked up to your car will be tiny though. Even if it wasn't, your car's not set up to burn it. Even if it was the amount of energy you'd get would be much less than you used making the hydrogen in the first place.

"Even if it was the amount of energy you'd get would be much less than you used making the hydrogen in the first place."
In reality I doubt it can be done for reasonable cost. Hence the promises with no substance.

Basicly the trick to fooling people into buying this st is not to mention the drag the alt puts on the engine to make the electricity to make the hydrogen is more than the energy the hydrogen will provide or save you on petrol.
A few people have mentioned this now, it circumvents the laws of physics which, in a nutshell, mean that it's impossible to get out more energy from a system than you put in. t is not to mention the drag the alt puts on the engine to make the electricity to make the hydrogen is more than the energy the hydrogen will provide or save you on petrol.Edited by S0 What on Saturday 30th March 18:49
If you scaled up the hydrogen generator based on the claims made, you could do away with petrol and run on water entirely
. (obviously you can't, just in case anyone didn't pick up on the subtle sarcasm
)I ran across this while looking at cars on eBay. One particular car was advertised as fitted with this kit - usual stuff, lots of too-good-to-be-true claims and the listing was written by someone with no idea of spelling, grammar or punctuation.
Still, curiosity piqued, I clicked the link to some website flogging this HHO tackle. Sure enough, it was your standard sthouse website for snake-oil peddling: designed and written by somebody with the mental faculties of a toddler. Fatuous claims about performance, plenty of tiny pixellated excuses for photos, etc etc.
The theory is reasonably good: you certainly can use electricity and water to make oxygen and hydrogen. Basic electrolysis. But it's inefficient and utterly pointless to fit this kit to a car - as already said it'd take far more power to run the plant than you'd gain from burning the hydrogen it produces.
Scaled up, running from a solar panel/wind turbine and storing the hydrogen in a high-pressure cylinder (and why waste the oxygen? store that too, sell it to oxy-fuel welders!) would be a practical application. But it would require a lot of expensive, complicated kit to separate, handles, compress and store the gases, not something you could do in your back yard.

Indeed. For the amount of hassle it would entail you would be as well off just compressing air directly and then using that to run a motor, like Peugeot have done. At least it's not explodey.Still, curiosity piqued, I clicked the link to some website flogging this HHO tackle. Sure enough, it was your standard s

Isn't it possible that burning petrol/h2/O2/air instead of petrol/air might give you better fuel economy though? Obviously no gain at all from using the b2/O2 mix as fuel... But as an additive?
Yes, possibly, although I dare say the engine might need tweaking slightly to make the most of it.However, whether or not the improvement in economy from burning the mixture outweighs the reduction in economy that's going to result from the parasitic losses induced during the production of the H2/O2 is a different matter.
I suspect not somehow.
