Hmmm. Yeah. Well. I've been standing aside on this one 'till now.
Now CharlieM you say you are actually DOW site cheerleading for project funding, eh?
Twice now recently you are pushing cooking down to; and then into the ground burying hard won carbons FUELS as a benefit, eh? Sound's like my fellow Washington State'er "Dr" Heard. That fellow grinds up and cultivates/bury's in wood charcoal onto some of the already richest river outflow river delta soils in my state.
All the while using Alaskan Dino in his personal vehicles; jetting around (Gore-like on lot's of Dino) eco-preaching; and home heating with long piped in Canadian "natural gas" That ain't. Natural that is; as supplied and used. Just ask those living where it is frack'ed/extracted and washed/cleaned to "natural".
I'm a life long use site grown woods for fuels power guy.
Simple logic test for you.
PNW tree woods only ~1/3 of the stored energy potential is in hydrogen/oxygen wood molecules. ~2/3rd the usable energy is in the plant air removed; solar energy linked carbons chains.
So how can ANY energy system economically work self-sustainable when you carbons sequesters insists on bury locking away 2/3rds your energy, eh? Your new plants growth air carbons, eh? Plants do not directly uptake carbons needed for cells walls from the ground soils. They get their new growth carbons from the air and the waters. Tie up the carbons - de-plant/de-green the planet to cold, dry and arid. Like many places already driven into.
DavidB is right.
Do something personal, useable, and prove your assertions.
Last month I/we replanted 2986 trees to replace 685 harvested.
Cool rain the last three days had me with visiting out of state company building and maintianing low fire woodstove heating to dry and dehumidify: pants, coats, shoes and dogs. Pretty to look at too.
~60 pounds of wood fuel used in every 24 hour period. With ALL of the in stove produced woodchar directly utilized for sensible heat power then within the woodstove. "Saving" back the wood char from experience would have then needed 3X the raw wood input, driving me up to 180 pounds a day wood useage. I ain't popular culture hydrogen energy sooopid-fied. Ha! Stooped a bit from 45 years wood for personal energy bending/stoop/sweating the fuel woods.
DavidB is right.
Make your self Real, familiarized by wood for power actually doing things. And do this like all DOers here, on your own dimes.
