Hi All,
New Springtime day, new thoughts, new developments.
CodyT had found a December 15, 2015 video interview of an early Joni’s bumper mounted woodgas system. I will cross post here. We will get to hear Joni speak:
DO, CC enable and translate the text of his talking.
This is no doubt a very early Joni development. Compare this with the top of this topic with his much later, many steps evolved Kolyvan 9.0
More than just the outer simplification of a good evolved design will be apparent if you compare the line drawing internal illustrations on this topic, and on his earlier system 8.0 topic.
Plus in the text of these two topics his answered questions to his in-engine compartment, and internal engine improvements.
This was the new developments.
My new thoughts are actually similar early experiences.
I’ve been PMing a new DOW member asking me question on imo for best approaches. Which system to start with. Then we phone talked too.
Ha! Always later ideas/experiences come to mind that I need to convey to him. Better here to many; versus just to one.
Most vehicle guys DO on; or within the wheelbase of the vehicle; mount their woodgasifier system as Joni did.
Reasons why for this versus would seem to be easy just trailer mounting the gasifer system. Others have stated the obvious of two space parking spaces needed. Difficulties backing up. Vehicle loaned out, and it always comes back trailer and/or gas pipe damaged.
Here is my learned bad gasifiers on a trailer experiences. Trailers hop and bounce hard. Especially over traffic bumps and curbs entering or exiting. This jolting breaks down, and packs the need to be flowing char beds. M-a-y-b-e O.K. if the gasifier is in-operation with gasses flowing, internally “fluffing”. M-a-y-b-e O.K. IF you have excellent hard char internally from a superior hardwood like Nordic birch.
Crumbled pack tight death on a non-working system been fueled with soft charring woods.
There should be No Maybe’s in a critical need-to-use system. It must work, each and every time, needed.
Put the wood gasifier system on the vehicle for best smoothest ride and most consistent results. Put the don’t-care, bagged wood fuel, tools, and luggage on the tow trailer. Then you can really cramp tight backing up. Or detach and drop the trailer completely.
Read, observe, even ask what the system designers range-hours of operation expectations are with his system.
VesaM and his Finn fellows want 200-300 kM (120-180 miles). Say 4-6 hours loaded operating time.
WayneK and other building faithfully his system expect 50-100 miles (90-180 kM). Say 3/4 to 2 hours.
Joni says his is made for 35-50 kM. His work commute. And, “not to shine to the public”.
Well that is in-my-opinion near perfect for a woodgas electrical generator system. Smaller engine lower loaded being 2-3 hours batch cycled. ON RAW WOOD FUEL. Any raw wood fuel.
No charcoaling promoted as the easier way. Really? For some maybe. If you have hardwoods. If you have the wiliness to do all of the charcoaling steps past the wood splinters stage.
I’ll still stick to raw wood. With the electrical generator systems wastes heat pre-drying down the woods. You can use up to 40% wet wood then.
Anyhow Joni speaks again.
