Producing hydrogen from biomass involves either biological or chemical conversion of the biomass. The biological process generally involves a number of stages to produce a hydrocarbon from which hydrogen is extracted. The hydrocarbon is produced by anaerobic digestion while the hydrogen extraction typically involves steam reforming. This last part of the process is the main hurdle for biological processes because steam reforming requires large mounts of energy that make the process uneconomical. Generally, biomass is considered to be a distributed energy source, produced and processed close to where it is harvested. Small-scale steam reforming becomes very costly because of inability to recover the heat from the steam, and the dominance of capital outlay costs for the reformer. Chemical conversion of biomass, besides being expensive, produces emissions in the form of tars, phenols and acids. Candidate biomass materials include: a) crops grown specifically to generate hydrogen; b) animal wastes; c) human wastes of which sewage and industrial wastes from foods or chemical processes are a possibility. The key to improving efficiency was felt to lie in shortening the lifecycle of candidate biomass materials.

Hmm, biomass, not that exciting really.

On the subject of this water power thing: I had read it, I just didn't realise that was explaining the power source :rolleyes: I am well aware of the energy changes (including source and destination of energy) in nuclear fission and nuclear fusion, and I have a reasonably good knowledge of particle physics, though I'm not an expert. I don't want you to be simpler, I think I need a more technical explanation. You start with plain water, right? After you burn the fuel, your waste product is plain water, correct? Are there equal quantities of water input and output?

Can You Explain ....
At What Statement you really feel like ...
All this is a Hoax . ??? ?

I am Willing to Explain ! :)

The reason I am so sceptical is because I have heard of schemes like this before, and they have been proven to be useless. It seems very odd that you could split water up, burn the hydrogen, resulting in identical quatities of water as you started with but having gained energy from nowhere by burning the hydrogen.

If there is a reduction in mass or there is some external energy source I have not noticed I can accept that it might be possible since it would not go against the law of conservation of energy.

The Energy is not from SomeWhere.
It is the Chemical Energy Stored in a H2O covalent
Bonded Molecule.

By Inducing the Breakage of this bond by say..Electrolysis (You need a Power Source for this but it is lesser in Magnitute than the final Output as a Whole)
We could release a Quantity of Energy.

again repeating this :
The polar pulsating frequency applied is such that the pulsating
electric field induces a resonance in the molecule. A cascade effect
occurs and the overall energy level of specific water molecules is
increased in cascading, incremental steps

all this still at the same Power Input.

The Hydrogen recombines with oxygen during Combustion to Give out Energy + water Vapour. The Heat Generated in the Process drives an Engine.

No..Mass is not converted to Energy anywhere.

Very cool stuff Active. Thanks for the information!

So you are saying that the energy comes from nowhere? I'm sorry, but that goes against one of the fundamental principles of physics as we know it. I don't believe it. Frankly, it's silly.

Look, if I've misunderstood then it's because you're not explaining it properly. Which reaction are you talking about? Be specific when you explain!

You CANNOT start with just water, split it into hydrogen and oxygen, oxidise the hydrogen and be left with the same quantity of water, and surplus energy. It's against the rules of physics. It makes no sense.

I find 2 things very odd about this thread:

1: It started off as a political commentary, evolved into a chemistry / physics lesson, then evolved again into the Jerry Springer Show (minus the toothless sibling lovers cheating with their pets on the trailer floor, of course).

2: I actually spent 10 minutes reading the entire post.

Well, for #2...if you will insist on reading this drivel :p
