Many alleged water-fuelled cars obtain hydrogen or a mixture of hydrogen and oxygen (sometimes called "oxyhydrogen", "HHO", or "Brown's Gas") by the electrolysis of water, a process that must be powered with electricity. The hydrogen or oxyhydrogen is then burned, supposedly powering the car and also providing the energy to electrolyse more water. The overall process can be represented by the following chemical equations:
2H2O → 2H2 + O2 [Electrolysis step]2H2 + O2 → 2H2O [Combustion step] Since the combustion step is the exact reverse of the electrolysis step, the energy released in combustion exactly equals the energy consumed in the electrolysis step, andeven assuming 100% efficiencythere would be no energy left over to power the car. In other words, such systems start and end in the same thermodynamic state, and are therefore perpetual motion machines, violating the first law of thermodynamics. Furthermore, under actual conditions in which hydrogen is burned, efficiency is limited by the second law of thermodynamics and is likely to be around 20%.[10][11] More energy is therefore required to drive the electrolysis cell than can be extracted from burning the resulting hydrogen-oxygen mixture.
So this b*ll*cks then?

"on a 3 litre range rover 30 % has been achieved"
Really? can't remember them ever making one . . .
yes ACTUALLY
quote from a user who is using it , and no i didnt sell it toi him and he installed it himself
Deluded from UK called me yesterday, Rover almost at 40mpg and he is delighted, sent me some pics but I couldnt open
on mobile phone.
He says he has an appointment with a psychiatrist but said he will not discuss on phone ??
