Is it possible to use wood gas?
In theory, yes you could burn wood gas as your heat source for a distiller. But don't make things more complicated than they need to be. The more complicated something is, the more chances you have to fuck it up.
Before you get too autistic about wood gasifiers, distillers, MREs, bunkers and all the other doomsday prepper stereotypes, start with basic disaster preparedness stuff.
You already have a gun, are getting ammo, and are practicing with it. Good. In addition to knowing how to use it, do you know
when to use it? Do you know how to avoid situations where you need to use it?
You're already gathering medical supplies, good. Do you know how to use them?
Do you have a long-term-stable reserve of safe-to-drink water? How long will it last?
How long can your home stay warm if the power and the gas go out? Do you have some alternate way of staying warm or keeping your home warm?
How much food do have on hand? Is it shelf-stable? For how long? Besides just bulk calories, will it provide the nutrients you need to not get nutritional deficiency diseases? Does the stored food require cooking? How will you cook it if the power and gas are out?
You're looking to grow your own food. Good. If the city water shuts off, can you get the water you need to grow your crops? Can you get enough nutrition into the soil to get enough crop yield to feed yourself? Do you know how to recognize pests and disease and take care of them before they completely wipe out your crop?
Are you on good terms with your neighbors? Will they warn you if someone tries to steal your car? Can you trade them your extra zucchini for their extra home-canned plum jam? If niggers try to steal your wheat, will they shoot, shovel, and shut up?
Are the civil authorities in your area on the side of the locals, or bought out by globohomo? Once hostilities turn kinetic, and belligerents destroy the Internet and cell networks to stymie enemy communications, how will you get instructions from your local authorities that you need to evacuate or hunker down?
The more you look at just how bad things can get in a hot civil war, the longer this list potentially gets.
From reading your posts here, I think you've worked yourself into a panic that the End of The World is 6 weeks away, and are trying to jump to all the advanced stuff you think will be needed to survive long enough to see the rebirth of civilization. Or perhaps you've autisticaly found a fun and exciting new LARP. Maybe a bit of both. You're trying to run before you learn to walk.
Stop.
Focus on the
basics first. A civil war would be like every possible disaster scenario at the same time, over and over again. If you can't survive a basic, more realistic, more common disaster, like an earthquake, freak storm, wildfire, chemical spill, or nigger riot, whether by evacuating or hunkering down, you're going to have an even harder time surviving a civil war.
Look up what your local civil authorities recommend for disaster preparedness for your area, and what disasters are most likely to hit your area. This information has become a bit harder to find since COVID, but it is still out there, and much of it is still valid. Start there, first.
