Hydrogen Hybrids

[bigjim]

Anybody got experience of these guys?

de Verde Technologies Limited - Home

Looks interesting:

Example from the site: Jaguar S Type 4 Litre V8 from 19mpg to 30mpg (local) 26-42 ( Motorway) - 4 Pegasus 700 Cells

Look at the testimonials, they are identical to the ones on

ROADRUNNERS HYBRID CARS

 

[moonloops]

I suspect the testimonials are fake - two different people call "round town" driving "local" driving?? Not heard that expression in the UK ??

I'm trying to understand what it actually is. It appears to be some kind of water injection system from what I can make out from skipping through the blurb.

Water is comprised of two atoms of Hydrogen and one atom of Oxygen or H2O which makes it perfect as a fuel source. Our unique HHO system will separate a water molecule into its component atoms (H H & O or HHO). We can do this using very little electricity, under 1 amp. This gas is then injected into the engine and oxidised as fuel. The resulting energy is 2.5 times more powerful than petrol/gasoline. This totally changes Combustion! The by-product of the combustion is water vapour. Therefore, as fuel, water is powerful, cheap and pollution free. The improvement in emissions and mpg far outweigh the energy required to produce the gas and this is a FACT! Please see our Testimonials page.

Sounds like they pass current through the water, and then inject that into the block...

I looked at Terms and Conditions - the page just says 'Coming soon'. I bet.

Haven't we discussed this type of thing before on the forum?

What happens here is a regular internal combustion engine, powered by regular fuel from a forecourt pump drives an alternator which produces electricity. This electricity is used to separate hydrogen and oxygen from a water supply and the hydrogen is burned in the engine instead of regular fuel.

Although scientifically sound it's efficiencies are questionable.

This looks a lot more promising:

The splitting process requires more energy than is released by the burning. and the Alternator/splitter isn't 100% effecient either.

Aparently most of these "HHO" gas systems get their fuel savings from leaning out the mixture to damaging levels.

While my high school chemistry would agree that the splitting would require equal energy to the "merging" (oxidising), can't you use a third substance?

E.g. if you put a strip of aluminium in water, the aluminium will promptly begin oxidising, which in turn releases hydrogen from the water, leaving you with a surplus of hydrogen gas.

Hence, if the system uses something other than electricity/electrolysis to split the hydrogen... why couldn't it work?

Admittedly, then the alu becomes a "fuel".... and the processing of oxydised alu back into "clean" alu would require energy... but this can be done off-site, running off of some pretty clean power sources, e.g. windmills...

The economy doesn't collapse as end-users still need to buy a consumable (alu), refilling doesn't take the hours it takes to recharge a battery, and you aren't driving a car filled with extremely volatile gases under high pressure...

They work by having layers of plates and just use electrolysis to split the water up. it's just a con sadly

 

[SimonD]

While my high school chemistry would agree that the splitting would require equal energy to the "merging" (oxidising)

The Splitting reaction (electrolysis) and the burning (combustion) steps are the exact same so as you correctly stated the energy required would equal the energy produced.

At 100% efficiency there would be no "left over energy" to power the car.

Your high school physics would help with this, the First and Second laws of thermodynamics

What they havent explained is what happens in a hydrogen fuel cell. I dont know whether this system works the way that they've described because they say 'it improves efficiency' ... but dont explain what it does or how it happens..... a bit suspect if you ask me

A fuel cell takes hydrogen and oxygen and makes water and electricity useful for running an electricaly powered car.

This device takes electricity + water and makes Hydrogen and Oxygen which is then burned in the engine with the fuel.

They usually are, but then they are not... what the marketing guys would normally do is contact satisfied customers and 'offer' them quotes to use in their names. So yes they would be written by the marketing people, but on the other hand they would have been approved by the customer.

Of course you can just go and fake whatever you like, but most 'decent' marketing agencies would simply do it as described above.

 

[crockers]

As far as I'm aware the only hydrogen fuel cell car on the Market is the Honda Clarity in California. Gather the process for making the hydrogen is very expensive.

So no snake oil solution.

A colleague at work passed their details on. He has another colleague at another office who has had this conversion done. I'll try and get more details from him when work starts back up after Easter.

I've just asked the colleague of the chap involved for an update:

the last time I was up in Rosyth he wasn't sure as he'd only been running around town. One fill up with fuel seemed like worse or no change, the next appears better. He's waiting for a long run. So I would say that currently the jury is still out on this one.
