I made a simple lean-to shelter of trees and branches using small axes and hand-saws and it took a long time.

yeah you still need gasoline for that setup.

I want to try my hand at manual felling and saws.

I've gotten pretty good at delimbing trees and processing the wood with an axe. I just don't have any saws to use.

You can actually run gasoline engines on wood gas without major modifications. There are EPA plans out there for converting cars and trucks. I imagine that if you're doing forest management, you can figure out how to run your lumber mill off the fuel that you're harvesting.

Wood gas generators were used in WW2 when petroleum was in short supply, especially in Germany where the shortage of gasoline was severe.

I "designed" (read: sketched out) a midget submarine circa 1995 that was intended to be run using a compressed woodgas AIP powerplant. Being a child, and fascinated by the process of destructive distillation, I shoehorned it into my obsession with U-boats; I planned to use oxygen obtained by electrolysis for both combustion and breathing gas, not realizing that the electricity needed would of course be better used in a straight electric propulsion setup ^_^

I think I have a PDF lying around someplace with schematics for a vehicular gasifier; I'll try to dig it up for you guys later.

> 5500 kJ/m3 -> Btu/ft3 = ~147

Natural gas is like 1000-1200. Poop (digester) gas is 550 to 600. Landfill gas is like 350.

This sounds like the worst fuel possible. What the fuck. The only thing going for the woodmobile is that it runs (poorly) on firewood. Considering the amount of CO in the fuel, I wonder what kind of emissions the engine puts out. (Maybe it gets used up.)

My buddy is currently accumulating funds for a sawmill. Combined with the hydroponics setup that he has, our stills, that Chinese diesel pellet mill that we got a few years back and a few other things and we should be pretty well apocalypse-proof.

That's it entirely. If you've got nothing else you can still use wood. Until the wood is all gone.

Many diesel engines can be made to run on straight vegetable oil, no need to convert the oil to biodiesel.

Yeah, but my reading indicates that SVO comes with a few issues of its own, notably gelling and oxidative polymerization, the latter of which can apparently BTFO an ICE in fairly short order.

Besides, with biodiesel, I'll be able to just pump it straight into literally anything that takes diesel, from my second-echelon standby generators, to an old Muhsaydes TDI, to a fuckin' bush plane without having to fuck around with any of their gaskets and seals and whatever the hell else.
