Power an engine, like I said oil crops and diesels make more sense for
some and which feedstock depends on your location's climate. "FROM
FRYER TO FUEL TANK" by Joshua Tickell is the best
diesel/SVO/Bio-diesel book I've found.

Have you looked into Listeroid diesels?

When I ran those numbers I came up with firewood, partly because of
the lower cost and hazard of storage compared to liquid fuel. The DIY
mechanical investment was a Sears garden tractor to move it and a
logsplitter, both obtained second-hand and rebuilt. Distilling
methanol from it doesn't make sense to me, the gas to run tractor,
chainsaw and splitter is perhaps five gallons a year.

An extra benefit is using the wood stove to heat-treat steel, which
other heating systems don't allow.

I grew up with forced hot water heat. The coal and then oil furnaces
heated it to 150 - 180 F. There were several zones each with its own
circulating pump, so the system didn't operate when the power went
out. It did work pretty well in an old, poorly insulated house because
different areas had their own thermostats, so for instance we shut off
the upstairs bedrooms during the day.

Gotta go cut more wood now...

Out of curiosity where do you live. My grandfather heated his house,
in up-state New Hampshire,  with wood for most of his life. Granted
that he cut all his wood by hand, but it took him basically the entire
month of October to do it and the "wood shed" was a building about 30"
long and probably 15 or 50' wide and he sawed the cordwood up in stove
lengths before he stowed it in the woodshed. this was a two story New
England house built, probably sometime in the 1800's.

My other grandfather, 60 miles south of the first one, simply closed
off all the rooms and they lived in the kitchen for the winter. That
grandmother cooked on a wood stove so they didn't need any extra wood

I'm in southern NH. The house had electric heat when I bought it,
meaning it was relatively well insulated, and I've tracked down the
losses and improved it enough that around two cords a year is enough,
with warm clothing and some rooms closed off. At that level of use
I've never needed to buy wood, just collect the dead and fallen trees
from friends' properties, land clearing, storm damage, etc.

My wood sheds are framed with tree trunks and recycled lumber and
roofed with corrugated steel. The floor is old pallets blocked up on
scrap pressure-treated. The roofing and lag screws are the only
expenses and they can be reused.
