This is useless, you spend more energy to produce H2 and CO (by pyrolysis of wood) than you gain by burning them. If you use charcoal or heat from solar energy will be profitable.

If you are referring to this trivially simple demo, I agree.

[dragondoubt]

I don't get the point of the experiment. Maybe there is a practical application, but I lack the imagination to see it.

[dacroz2]

It is just a simple demonstration of how organic material (like wood) can be gasified by heating it. The gas can then be cooled, scrubbed and burned in an engine or water heater etc. instead of natural gas or propane, for example

[dragondoubt]

@dacroz2 Yeah, but that's only practical if the energy used to heat the organics is less than the yield of energy provided by the heated organics.

[dacroz2]

True. But that's not the point. This is just a simple demo showing how easily one *can* drive combustible gases from wood by heating it. In this case I used an external heat source only because it was convenient. I could have done something more complex.

i suppose if you had used wood to heat it then the  meat heads would get off your back about wasting fuel , but thats ok some of us acctually understand the point of your demonstration

@dramey03 I found a guy on here that is doing that, cant think of his handle but search "compressed wood gas" and you will find him. He just put out a new video yesterday of him running his old truck with a big bottle of wood gas that he filled with a compressor.

i wonder if one could find a way to connect these fittings to a propane tank and possibly "fill" up a propane tank with the gas produced

being able to store in a propane tank would create a great deal of uses for this and they would make great long term storage containers

[dramey03]

for those who dont understand it, its a way of being efficient

at the same time you produce charcoal, you create a sort of natural gas

i like the use of fittings on the can, this would allow you to use a regular camp fire to heat can, and then with a longer fitting, you could supply the gas from the can to literally anything else, to be used instantly or stored for later use

through the simple fittings you turned a regular old charcoal maker into a dual purpose system

well done sir

[MrInventWorld]

Great demonstration.

Bio gas is a good way to produce usable gas just a matter of getting some containers and almost any biomass grass poo table scraps human poo cow poo chicken poo any will do. Mix with some water and let it sit you will have some gas in a couple weeks. Make a few plants and you should have a constant supply of gas use one mix one. Look in my favorites there are people in India that no longer use LNG they use only biogas.

@dragondoubt - FEMA is distributing a PDF on how to build a gasifier during national emergencies when petrol is not available. There's a very detailed introduction here: v=577mirKXK8I

Cool...
