I understand via Fox News that someone has invented a new fuel gas which consists simply of water, somehow electrolyzed to form "HHO gas". It is said to be useful in torches, and also as an automobile fuel. Details are somewhat obscure but it appears that this is handled and burned as a single gas, not as separate hydrogen and oxygen as in most such systems. Does anyone know anything more about this?
I saw a website a while back (can no longer find the link), that said producing very small quantities of Browns gas (HHO) and mixing it in the petrol air mixture, gave a massive increase in efficiency.
Thank you Aardvark,That's exactly the kind of info I was looking for. So there was a small increase (15%) in efficiency, not exactly the double yourmileage that some of the HHO sales websites promise.Still with current oil prices it might be worth someone's time to see if they couldget a slightly higher efficiency and clean-up any polluting problems but it's probablynot going to change the world after all. Although if all the millions of cars on theroad had a 15% efficiency (by this or any other method), that would be a large saving nationally.
This is my first post so please be gentle with me, my back ground is aviation 20+ years.With regards to HHO, I have recently fitted an HHO unit to a fleet operater's vehicle (six cylinder sedan).This vehicle was tested at an independent accredited emission testing station and driven by the operator for 1900km at which time it was retested at the same test station, the results are:NOx reduced 74.12%CO2 reduced 15.43%Now this is the one I want to know why PM-LLSP increased 120.6%Opacity Av(%)reduced 97.89%Opacity Max(%) reduced 93.26%Power dropped 1.41%Torque dropped 4.98%Fuel economy increased by 34.08%These are not my figures they are all independent. So something seems to be working.Can anyone help me as to why the PM has gone up? I think it could be water vapour being picked up.
PM-LLSP is the particle mater in the exhaust emissions.

They used 240 liters of H2 and O2 (at a stoichiometric ratio generated by electrolysis) to enhance the combustion. A 15% increase in thermal efficiency was observed.I've documented this on my website at http://aardvark.co.nz/hho_scam2.shtml and have also written other stuff at http://aardvark.co.nz/hho.shtml debunking this whole "run your car on water" scam that's appearing with increasing frequency on the web.I'd enjoy feedback.
