OSU engineer: Hydrogen system in autos a scam (!)

All this additional load has the same inefficiencies of the engine, friction and the alternator so even more fuel energy is consumed than the electrical energy produced.

Your assuming that the injection of hydrogen into combustion chamber has no effect on the engines efficiency.

"Sorry... if you have a battery that is being charged or overcharged as what happened when I experienced the accident *I* was in, there was no “hydrogen-oxygen” mixture."

You may chose to not believe me but try this source?

You appear to assume that the increase in combustion efficiency would exceed the energy requirements of the entire system necessary to produce hydrogen, including passing through the engine.

[ColdWater]

I have another energy aid for you. Mount a wind-powered generator on top of your car.

[DoughtyOne]

Running on empty eh.

[Realism]

It simply can't, unless there is some part of the process which is greater than 100% efficient

What? How can you make something more than 100% efficient.

[ColdWater]

“Running on empty eh.”

When one side abandons the technical argument if favor of snide comments, it is apparent that he has conceded the issue.

[editor-surveyor]

“It runs off excess power from the (frictionless) alternator.”

Perpetual motion has always been our best hope ;o)

[thackney]

What? How can you make something more than 100% efficient.

Now you are begining to understand why it cannot work this way.

[DoughtyOne]

Yes, I understand that you have. I have no problem with that either BTW.

I asked you if you had seen this product in person.

I asked you if you had studied this product in person.

Your response was to suggest I place a device on the top of my car.

Our cars do in fact have a device on them that utilizes wind flow.

[Realism]

Well since none of these components are working at 100% efficiency apparently there is room for improvement.

[editor-surveyor]

D-1, a diesel engine already has hydrogen to burn from the diesel fuel. That hydrogen produces less than 2% of the energy that the engine produces. Adding more hydrogen will do nothing for the combustion; adding more carbon would do a lot, but the only way to do that is to put a bigger fuel pump, and bigger injectors on the engine. Unless you have a bigger load to move, the above would be useless.

There is no fairy godmother of fuel efficiency.

Used to generate power?

[editor-surveyor]

"...he doesn’t know he believes it won’t work!"

Engineering anyone? Hydrogen is the lowest energy fuel on the planet. Every other combustible produces more energy, even marshmelows.

[thackney]

And to use fuel to generate rotation to generate electricity to generate hydrogren applies all those inefficiencies to the process.

[ColdWater]

“Our cars do in fact have a device on them that utilizes wind flow.”

Interesting. Care to elaborate?

[editor-surveyor]

He didn’t bother to say “Gas is MORE explosive than hydrogen”

Because it isn't.

Gasoline produces far more energy than hydrogen, but it is not nearly as combustible as hydrogen. The hydrogen molecule is the very smallest, and thus it is the most explosive in a perfect mixture.

[ColdWater]

“Engineering anyone? Hydrogen is the lowest energy fuel on the planet. Every other combustible produces more energy, even marshmelows.”

Hydrogen has three times the btu/lbm of gasoline.

[editor-surveyor]

"Well since none of these components are working at 100% efficiency apparently there is room for improvement."

Few things on earth are as efficient as a high compression diesel engine. Nothing can work at 100% efficiency except a nuclear reaction.

[ColdWater]

“Nothing can work at 100% efficiency except a nuclear reaction.”

Then why do our nuclear reactors run at about 33% efficiency?
