Dunno, why don't you buy it and tell us all

The problem is the guys who buy it never share their results with the test of us.

I'd spent a fair bit of time reading and thinking about this and came to the conclusion that it's a complete load of rubbish and a waste of money.

1 - Making browns gas (hydrogen, oxygen and some other stuff) takes much more energy than you get back by burning it in an engine.

2 - The only way it "may" improve things is if it makes your fuel burn faster or more completely. The problem is the quantities produced are so small they make no difference and the combustion's pretty damn good anyway.

3 - Most of these devices are crude and inefficient.

There's been plenty of studies disproving these things. If it worked it would already be in your car. You'd get more benefit rebuilding your engine with a high CR and injecting the water directly.

Well Dunno, there is a kind of simple answer and if I remember correctly in thermodynamics, it takes just as much energy to separate the hydrogen. In theory it's do-able but we haven't worked out the major kinks yet (carbon - fuel storage etc). So in practicality, were not even half way there yet, but we will be soon, i'd say within 10yrs. Every major car manufacturer is going hard at it. By the way , the land speed record for a hydrogen car was 450 km/h at the Bonneville Salt Flats in 2008

Reduce your fuel bill. Increase your electric bill.

I,m with Lamb when he says a waste of money but not entirely rubbish. I think Bio-fuel will merge before Hydrogen. but that too will be short lived. But it makes you wonder what fuel we'll be using in 20 yrs !!

Electric cars were first, are best, and will be the future. Whether powered by batteries or by hydrogen fuel cells, its going to be electric.

Sssssnake oil..............

I think hybridising your fuels even by using browns gas is worthwhile from the peeps I know use them.
Theres one chap in his 70s who has been running a similar setup and definitely has better all round response, cleaner running and better sounding through the revvs.
For a novice its hard to pick up but those in the know can just pick it up by sound and feel.

I and others I know have run various additives in cars and have to say some do work. You definitely notice an improvement in some brands of fuel injection cleaners for example my old campertruck cannot hit 150kmr anymore with its 8:1 comp 2lt (probably less comp now) yet when I use the nulon red crap the engine feels noticeably better and reaches this speed on the same stretch of freeway and roads.

After someone putting up a list of paint chemicals Im willing also to try them to see if certain amounts can improve response at least apart from fuel economy.

Fuel efficiency is not govern by governments or car industry its up to the consumer and things are definitely changing for some of the sales but not all as theres still the SUV mums.

The best way is to go on the browns gas forums and spend time there reading posts and seeing the results of enthusiasts as that link shows more of a con artist effort to make money.
