Woodgas meetup 2021

One suspects that if it pencilled out to be close in efficiency, oilpan4 would be all over it.

A few of the forum members have said it's not usually worth it unless you already heat your home with wood. Otherwise it becomes a big hassle. But that may not have been just because of financially/efficiency. Many want to have their own place off grid and this lets them decrease dependence on gas/oil.

It's pretty difficult to standardize wood.
Best bet is wood pellets as they are ran through a pelletizer, where brute force forms wood pellets during which the wood heats up to the point where the lignin melts, which is above the boiling point of water and then its sealed in a plastic bag.
I use wood chips and round wood from my land to heat my house so I am kind of all over it.
If you want 20,000 btu per pound any rubber or plastic will provide that.

The most standard unit of wood is the pallet.

Pellets was my suggestion as well.

I'm producing more PLA fragments than sawdust, lately.

That's why I would consider wood gas if I had a country estate where I could source firewood in a sustainable way, or to burn combustible organic residues harder to use as an ethanol or biomethane feedstock.

You should be able to get 40 miles to a pallet.

[Piotrsko]

Is the 40/pallet because of the energy content or should we be that efficient?

[oil pan 4]

That's the wood gas cars.
Seems like the most efficient use of wood gas would be to charge electric vehicle battery.

[freebeard]

This calls for a wood gas ICE, external combustion steam or Stirling, and serial gas-electric hybrid race-off. Let the best wackadoodle idea win.

I think if you just insist on burning something or when wind and solar aren't available the best idea is a steam driven generator charging an electric car.
