Hydrogen on demand Kits : Improve Fuel efficiency by 50% ??

Came across this recently..

Some of the claims are pretty extroardinary

Sounds like someone selling the idea of a franchise rather than a product. Don't expect much in the way of hard facts and plenty of hyperbole.

Short version:

HHO or Browns gas and the method for making it
(you make it when derusting by electrolysis for example) has been known about for years.
Does it work? yes that's been proven
jewelers have been using it in torches when soldering precious metals

The biggest snag is efficiency, ie the amount of energy produced compared to the energy used in making it.
There are youtube videos galore on this subject so if its on the internet it has to be true right?

If say your bikes charging system burns off unneeded energy as heat, you could instead divert this energy to create HH0 and pipe
it into the manifold.
the process is pretty simple really

From here on we hit the snags
My bike (500 twin) for instance sucks in 250ccs of air for every revolution
At 1000 rpm that's 16 times a second so 4000ccs
If I want to add just 10% of HH0 to the mix I need to produce 400c per second and that's just at tickover !

Offhand I don't know how much energy is needed to produce any given volume of HH0 but I do know you don't get owt for nowt
and you will need to use more energy to produce more gas.

If someone finds a way to make shit loads of HH0 for next to bugger all yippee! free, or at least cheap, fuel.

Some simple thermodynamics.

The average dissociation energy of the H-O bond in water is 458.9 kJ/mol. This means that to strip the hydrogen atoms from the oxygen atom takes 458.9 kJ of energy for one mole of water. 1 mole of water is around 18 grams.

So, 1 g of water needs 27.4 kJ energy to strip apart.

To do 1 g per second needs 27.4 kJ/s = 27.4 kW of power.

So, to get the hydrogen out of 1 g of water per second needs 27.4 kW of power. That's about 37 hp.

The spec of the magic machine states it runs at a maximum of 7A from a 12v supply. That's 84W of power.

So at maximum chat, assuming 100% efficiency, this thing can deal with 84/27,400=3 mg of water per second.

3 mg of water will yield around 0.33 mg of hydrogen. 0.33 mg of hydrogen is around 0.00033 moles. The energy of combustion for hydrogen is 286 kJ/mol. So burning our 0.33 mg of hydrogen will yield us 9.44 kJ of energy. If we do this every second, that's 9.44 W

So for an 84W input, we get a 9.4W return. At 100% efficiency.

If anybody wants to check my working, feel free - I did this in a hurry and may have missed a factor somewhere.

Thanks Fellas,

I was hoping someone would come in with some 'SCIENCE bitch!'
and explain why its too good to be true.

For the record, I did do a search, so apparently im the first guy dumb enough to entertain the thought of it on this forum

But it does make a good-sounding franchise....

Think of how driven the auto-industry is these days in terms of hunting for efficiency and driving down emissions.

If these things were remotely useful they'd be fitted as OE and pushed hard with a load of eco-wank

The road ahead is clear!
