Great picture and article reference you have put up DougB.
I had only seen/read of the sawmill sized “Missouri Gasifier”.
I really like the sensible cooler/condensate/gas wash unit shown in the illustration.
Also in this early 80’s period is a searchable Alaska fellows sawdust engine powering gasifer. He was compacting the sawdust into a center hollow fuel slug then controlled gasified from the inside out. Also the same time frame of the LaFontaine/Fema, India H.S. Mukunda developments, the Hill stove and the others like the Larry Dobson works.
Yep. Lived through this time period too. I was there, involved with DYI electric vehicle work.
ALL KILLED OFF AS YOU SHOW BY PLUMMETING CHEAP OIL. Thats how the smart money people did it back then.
Today the development killing factors will be from then oil and coal companies now morphed into Energy companies in bed with the now evoled organized Urban Eco-Greens to make all biomass (Trees!) harvesting and burning for any reason as “polluting”, “Resource Selfish, Greedy”, and therefore needing registering, regulating and then step by step illeagalized.
I have family in Missouri, Kansas and Texas. They do not see, or live with this . . . . YET.
Living in one of the three west coast “Green” states this has been a reality very apparent since the early 90’s. Many places in California now illegal to burn anything, anytime even in the most advanced fireplaces and woodstoves. They now have the homeowners insurance companies on board with restricting all residence biomass space heating now too. State regs here in “Green” Evergreen Washington are stricter than the Fed EPA or California CARB driving manufactures out of the market and 2-3X driving up the costs of all buyable systems today. State chartered Insurance companies here now buying into restricting any form of “woodheating” now too.
Very apparent this time the smart money does not want to lose the profit dollars suppressing the energy “competition” with price pulldown (our recent single last Spring refinery incedent driving up three state prices for 8 monthe to $4.50-5.00+ a gallon) but use Eco-Greens politics and voters to regulate suppress any supply competition to them in favor of their own controlled “clean”, “lowest carbon emitting” Natural Gas production and supplies monopolies.
The politically active urban Eco-Greens do not seem to realize they are being monopoly used. Not living Rural with thier own solar/bio-mass resources I now often get regionally even locally the attitude commonly that I AM THE greedy resource hoarder.
And I and the other Rural living here think they are just too lazy, self absorbed and indulgent to IPod/electronicaly/Matrix disconnect, put down the pizza pies, green energy drinks and get out and actually hoe the earth to eat and cut some wood to warm with.
Their way is now the anti-thesis of personal human Freedom and Independence. Insect societyists: too busy tweeting, facebook antenna brushing to actually go out and make dirt fly, or welding/fab smoke in the real world. Consumers - not Producers.
Solution? For personal human Freedom keep doing, pushing the regs, the edges, even into DYI energy bootlegging. And as I have to now in Washington state pay actually more per my harvested BTU to retain this personal Independence. Wait for their stupid living off use one time only Earth banked up cheap easy hydrocarbons savings banks to dry up. Keep evolving modern sensible ways to live today, and tomorrow, on the annual energy falling on the face of the planet. Think, live, evolve human sustainably in every day, every way. We are the only species capable of breaking out of the boom and bust population/consumption trap.
