Fellows let me clarify myself.
I have with much years personal working; and inputs from decades searched out, worked with respected achiever-of-results-peers, become truly excellent at just one thing:
Taking the Complex; stripping it down to one, two, at the most three, core values must-have-to-function factors.
Fail to satisfy any of these core principals and the system fails. Period. Throw all of the Inputs frue-fraw’s you like . . . the Output results will just not be there.
An IC piston engine system (Yes, with a plain’ol connecting rod and crankshaft) will always beat out any expernal combustion system because the IC engine is simple better Point-of-Energy-Release converting.
A barreled internal combustion GUN will beat out on the face of this earth ANY emitted ray-gun or rocket gun.
Most DIY energy Developers are NOT doing this for themselves, for use by themselves to meet a three core value of useabilty:
does this produce/supply potable water in usable quantities for a four person family?
Will this assist in food production multiplication for the annual needs of a four person family?
Will this produce sustainable the energy that four person family needs for annual heating, safe cold food extension storage, modest amounts of night lighting and media stored music and video entertainment?
I can and DO.
Two houses here 1300sf and 1500sf (three toilets, 8sinks) will be cold season heated here on just 6 cord of site grown and harvest wood. My fir soft wood is low dnesity bulky. True heavier hardwood and I crow about only 3-4 cord usage. Samr stoves. Different wood use “hand” needed then.
I/we have done this for over 100 years. Use half the wood now we used to due to in-stove/woodgas/charcoal glow maximizing use-improvements in these last 15 years.
I CAN do the lighting of all now on just 400 watts. LED’s 2700k value.
I can full three station satellite TV system, CD music players on just 400 watts now too. Couple of thousand over the last 15 years to achieve this.
I could IF the Powers That Be would let me deep personal well supply us with all of out potable water on just 1/2 horsepower. The infamous “THEY”, will not let me. I waiting for those know to age die-off to have our own water-well un-remembered. Best I can do at this time is to Not have our well Remember and concrete filled deactivated “for Public safety”
Each and every appliance change as they have times in services failed; been half-the-use of inputs energy and water replaced. Sigh. These better energy/water efficient have all proven to require MORE use maintenance’s to keep functioning…
My/our 16 mpg rated old pick up truck gets 20-22 mpg. The older now 18-19 mpg rated 2007 medium SUV gets 23-29 mpg.
I actually only use in all of my small outdoor use engines 30 gallons USD of gasoline a year. Big year, last year I used 5 gallons of diesel. 10 years now on the same back-up for cooking 20 bl bottle of LPG.
AS WayneK answered me in the past why he did not woodgas his Mercedes engined sawmill,; his separate wood splitter and separate wood chunker. “it is not worth the effort to just use it for part of and hour.”
I, and any other really good Praticalist who CAN answer these three core values question will say:
WE do not have the answer for ALL.
Only for those willing to sweats work the problems. Daily.
No one else, at any time, has had, or will have, the energy-for-ALL answer either.
“THEY” only even get 10% all-use-the-same in 3rd-world countries; 50% in the USofA/Canada and a few others, 75% Japan/Western Europe All/Same/Better energy usage when they insist on energy supplying/use-monopoly by only them.
Nope. I do not play the Monopoly game. Boring. Juvenile.
More fun to go out and make an IC engine run for a worked purpose. A producing TOOL. Can’t have the kids playing with tools too young.
