One point I've seen made several times is that hydrogen, because it is lighter than air, tends to rise as it burns. Pertroleum based fuels stay on the ground and tend to cling to things as it burns. Also, the smoke from petro combustion tends to be highly toxic. While explosive trauma can kill, a lot more people die from asphyxiation.

It's not so black and white.

One system is to combine a hydrogen fuel cell with an electric battery system. Electric over hydrogen fuel cell? The idea is that you can use a much smaller fuel cell because the battery handles the peaking demands. A few things to be worked out for sure.

Ok, I have a PDF several pages long a book with a bunch of stuff in it. How do I post it.

put it on a web site and make a link to it

it's probably a to big file to post it in a post

If you go to the advanced screen then you can attach a pdf to your post. PDFs can be up to 9.5Mb long.

The Hindenburg was basically painted in jet fuel which was said to be a much bigger factor than being filled with hydrogen.

Hi Clyd3
I don't know if SA rocks when talking about alternative energy, but maybe one day we can help out. Otherwise SA has its share going for it.
I'm up in Harties - NW
3v0, do you have some documentation, or link, on this combination technology?
killivolt, can you not do it in a sticky or something, maybe ask Bryan1 or Nigel Goodwin.
I want to get involved with alternative energy, bigtime. It's just difficult to start by yourself, everything is so bloody expensive.
go well all

I do not even recall where I read or heard about it. But it makes sense in that it is a combo of two things that work. The big hangup is the cell cost. A while back I seen people were working on DIY fuel cells. That is all I recall.

Bummer 3v0

I do not know too much about fuel cells myself.
Maybe I will research on it a bit and see what I can come up with.
But right now, I have way too many assignments to finish off.
I want to still experiment with stirling engines as well, see what sort of power one can get from a real world machine, not these stupid can designs.
thanks

People are still trying to blame the paint! I'm sorry but a sanity check should be instated at this point! Yes, the doped paint skin could possible have aided in the initial ignition, or shortened the total combustion time by a few seconds but it wasn't more dangerous that 7 million cubic feet of hydrogen gas that the blimp held.

Thanks so much for all your imput.
The generator I am building will produce hydrogen to supplement fuel consumption. NO STORAGE. The Danger of backflash combustion is nominal as there is very little hydrogen that is not being consumed. There are two seperate flash chambers to prevent flashback. I will keep posting as I progress.
If anyone accually gives this a try let me know how it goes.
Hydrogen is one of the answeres to the global warming problem. Do some research and you will see the great potential of this alternative.

Have you found information on what frequency and duty cycle generates the most hydrogen per watt of power. Efficiency?

Yes the main electrodes operate at between 240KHZ to 40KHZ then the coil operates at 1/1000 of that to produce Parahydrogen. The variance is due to the throttle action.

Duty cycle of about 2:1

My point is/was that it is over hyped. There is more crap surrounding it then the disappearance of Jimmy Hoffa or the death of JFK. To point to it as a reason not to use hydrogen is questionable at best.

The video shows the fire burned for aprox one minute if anyone is interested. It was a slow burn comparted to explosion one sees when propane is vented form a vehicle in a closed building. I expect hydrogen does make a good fuel air explosive given the right ratio.
