Woodfuels are NOT STANDARDIZED fuels.
There are many books and on-line reference sources that list this out by tree-woods species.
Virtually nothing published up on the wide range of BTU’s, and the energy release rates of different "cuts"of a tree within a given species.
Let alone the wide differences of remaining ash even within different cuts from a single tree of the same species.
Why does this make a difference in using wood-for-powers??
THIS is the factor that will always make wood-for-power an Automation FAIL.
Not about the automation sensors, servo’s and control logic problems. Of which there will be many.
Go back to the transition from actual whale oil, and olive oils for lighting to the first roughly boiled out coal-oils and petroleum tars lighting kerosene’s. Historical reference stories were with these you never knew from supply can to can whether it would soot-smoky hardly illuminate burn; or flare-up nearly explode.
Go back and re-read the story of John D. Rockerfellers development of the Standard Oil Company. He used Lab chemists first to find the right illumination oils characteristics. Then had them set the “standards” for that. Then had the production plants engineers develop the techniques and in-plant product testing to insure that each and every can’o branded STANDARD Oil was consistent and safe. This was in the late 1860’s, early 1870’s.
Now 150 year later we expect every Honda engine of the same model to perform consistently the same.
Every branded shirt and pair of pants from the same manufacturer to fit consistently the same. Wear the same.
Well folks in the real natural world organic products are NOT the same! A fish is not an all-the-same fish.
Why the best of wines are labeled with their grape species AND year of production.
Our standardized foods products are generally blended for a somewhat bland middle-of-the-road consistency.
Watch the cooking shows chef cook offs. A REAL Chef/Master Baker is expected to to take what ingredients are made available, and produce good results irregardless.
Want woodgas to work??
Put a good working human in the gas making loop with decision making capability.
THAT is how we 19th and most of 20th century built our more and more energy using societies.
The coal fireman were very experienced at getting the best possible results with widely varying fuels-coals supplied to him.
The steam engine operating engineers had to years learning work up to getting the best possible results from their double and triple expansion systems.
And as good seamstresses, and good kitchen cooks show well; woman are just as good at experienced on-the-fly getting the best possible results as men are. Women really are not clamoring for all-one-button dumbed-down lives!
To “standardize” any tree for a fuel to be able to one-button-use means rejecting out a high percentage of that tree as having inconsistent characteristics. Taking the remainder and grinding it up and reforming it into consistent fuel chunks. Consistency for store-abilty, automation handle-abilty, energy release rate and left behind ash percentage and fuseing
Huge, huge waste of Ma’Natures resources there to make your Marie Antoinette “fuel-cakes”.
Think about it. Any Dependency developer/manufacture/supplier wants you to trust their product. Become stoopid dependent on it to the exclusion of all other possibilities. Oh, but my chickens love stale refined white bread chunks! Would work to eat nothing else if I would just supply them exclusively with this empty nutrition white-crack-addiction.
Consistency standardization from Levi jeans/pump gasoline/bottled propane to cocaine/PCP/LSD/crank to anything else you would buy into is the name-of-the-game.
Be independent. Make do with as wide of range of input stocks possibilities as you can train yourself to get usable results from.
Sun don’t shine every day. Rain is a good necessity. Winter is a good reset/rethink time. I think Mediterranean climates would be so very mind/efforts numbing.
I love on-the-fly adjusting my winter space heating wood stove to wood-fuels variability. Much more fun and rewarding than one-button sending off a monthly payment check to the electric company.
