Good morning Marcus and happy 4th 
After a couple of weeks driving I expect no more than a few spoon full of condensate and a little soot at the slingshots . However I can dump a lot of water from the hopper and hay filter daily .

How did you make your hopper Marcus? (unless itās a WK secret)

Itās a standard wk design double gutters cooling tubes. I collect about equal amounts from hopper and rear tanks no matter the moisture content of my wood

How many tubes are you running ?

6 tubes made of 1 5/8 cyclone fencing post, and another one same size that acts as the drain for both gutters

Do you have a moisture meter for wood? I think your wood always has a high moisture content because of were you live. On the west wet side of the mountains with high humitity. If you could stock pile the wood up under dry shielter, I know just dreaming. But it would make a differance. Being a every day driver you can hardly keep up on the wood preping.
I think your gasifier system is running at full 100% max moisture collecting.
One thing I noticed that Jakob North was doing is when he stopped to refuel, he would open his condensation tank drain and let the water drain out every time he stopped to refuel. I was amazed the amount of water he was get out of Mikeās Gibbs wood. Not as much with my wood. And Mikes wood was in dry storage in the hopper for a couple years.

Iām doing the best I can and my ideal wood about as dry as I can get it is 9-10% mc taken reading with my moisture meter I got off Amazon. Yes I do frequently run 10 all the way up to 20% mc wood, and itās a dump every single tank and low spot every day process. The V10 will accommodate this with much larger tanks for long east side drives for hunting fishing and camping

It was strange I think, I have a big difference in how much water I get from the hopper, depending on the amount of water in the wood.
Do you have double walls on the hopper?
What is slingshot?

That is good and dry wood Marcus. You are really getting the moisture out of the wood and your gasifier unit is working great.
I have noticed in my driving if I drive my truck hard even with the really dry wood I have. I can get moisture up to my engine compartment sling shot water trap, not much.
Remember you are running a 350 cu. In. Engine that is not stock in the Toyota. You have a lot more engine then my 5.2 L so you are able to work your gasifier system harder driving down the road climbing hills.
It is a fact that you are not over pulling it and putting it into heater mode, that is good.
I am sure if you could get some of my wood in your gasifier you would see a change in water collection.
Just go with what you have and DOW.

This is what the jumper looked like in the tests they did in Sweden.
These received the best condensing, in their tests.
But since you have pipes on the outside as well, it must be better anyway, I would think.

These days, when I used the gasifier on the tractor to power a small engine, I again noticed water leaking out of the cooler and filter, unlike when the tractor is running, most of the water comes out on the funnel, but very little in the front of the cooler. My opinion is that it is not good to dry the atmosphere in the gasifier too much, I think that it works best and the gas is strongest when a small proportion of the water in the refrigerator is excreted and the hay in the filter remains moist, this also has a good effect on the filtration of the gas, because this way the filter retains all ash and soot. When I think about why the water vapor appears in the gas, the possible answers are that the water vapor from the reservoir breaks past the glowing coal or the hydrogen formed reunites with the free oxygen, ā¦ but according to the state of the temperature of the exit gases (the gas is cold ), reveals only the first possibility.

That is more than I run. I was running really wet wood in the mid west and in Oregon. Just the four I was using was able to pull out 2 gallons of condensate in two miles of driving. With that wet of wood I was getting water in the engine but still not much. When the gas comes out of the hay filter is there any sort of trap to catch and drain water before the engine. I have one and usually I donāt get much if anything out of it but when the wood was that wet I was getting water out of it.
This also doesnāt make total since because the wood I was running was very wet. I could squeeze water out of it with my hands kind of wet. You are drying your wood much more than that.

I have 2 low spot drains right in the rear corner of the front fenders and just behind the head light 2 slingshot filters and all of them together each day make up about half a gallon of water when I drain them out. Much worse if wood is over 15%mc, then I will drain when I get to work and when I get home as well every day
Makes me wonder if it has to do with the raised compression and aggressive cam in this motor drawing hard enough to pull water that far up the system. The hay filter is always cold to the touch so I donāt think itās a possibility I am still condensing out more moisture while the gas is heading up to the motor? But I could be wrong

Marcus, Jakob, donāt be harsh because Iām intruding on your conversation, but let me mention the possibilities of water condensation from the gas. As you state, when you gasify moist wood, the entire gasifier system, cooling pipes and filter are under considerable negative pressure, which is very unfavorable for water condensation, physics says that water in a high vacuum boils already at 20Ā°C, ā¦ in our case but it is very difficult to condense plumes from gas. The possibilities for condensation are either to greatly lower the temperature, or to raise the pressure, or to pass the gas through a dry absorbent material. I think the first option, cooling with air conditioning, makes no sense, the second option, raising the pressure with a turbine powered by exhaust gases would be the best solution for me, condensation of water and gas in a small overpressure, the third option, absorption, i.e. two filters made of hay and sawdust, since one dries with hot air, while the other picks up moisture from the gas, ā¦

Tone, do you get a lot of condensation from the ārefrigeratorā on your tractor?

Hello Don, it happens very differently, when the tractor is stationary with a small load, there is more condensation, say 1:1 against the condensation from the gasifier, but when the tractor is running with more power, the refrigerator emits very little water, I get much more from the gasifier, say 1:10. The cooler works very well, it is forced cooled by a fan from the engine, it enters the filter at a temperature of 30-40 Ā°C.

The state diagram shows us under which conditions (pressure, temperature) a substance is in a solid, liquid or gaseous state and when a substance changes from one state to another.
As an example, letās look at the water state diagram:
The axes of the diagram are:
x axis: absolute temperature (Kelvins)
y axis: plaque (Pascali)
As an interesting point, letās first look at an example from practical life: at a pressure of 1 bar (as much as the pressure at the surface of the earth), two points are marked on the diagram:
point represents the melting temperature. This temperature is 273 K (or 0 degrees Celsius); as we know this is the freezing temperature.
daddy represents the boiling point. This temperature is 373 K (or 100 degrees Celsius); as we know this is the boiling point.
Letās describe the diagram itself. We notice that the diagram is divided into three parts, where each part represents one phase of matter:
gaseous state of water (steam);
liquid state of water (liquid water);
solid state of water (ice water).
Here we notice a special point marked tt on the graph, where all three branches (a), (b), (c) meet. This point is called the triple point, and at this point all three phases of matter are in equilibrium: solid (ice), liquid and gas (steam). Or to put it another way: at this point, water simultaneously freezes, evaporates and directly changes from a solid to a gaseous state (sublimes). The point is located at a temperature of 273.16 K or a pressure of 611.73 Pa, which is about 0.6% of normal air pressure (1 bar).
This is translated from school literature, I did not write it

Yes Tone, a pure physics statement.
Very, very important relationship if you ever to understand and work with mechanical made refrigeration.
Marcus in real world PNW wheeler terms this is the good mudders and sand runners. His illustrated (a), (b), (c) line is where you are on the edge to traction and control yet still going forwards able to make time using the throttle as much as the steering wheel. Feeling-it. Seat of the pants controlling.
Pavement drifting.
Surfers have their own terms for this.
Gliders edge treading stretching out their flights.
Boarders, snow, water, urban have their own terms to.
A state where you are in a mind-space between awake, not-awake. Here in this world . . . or somewhere else not-of-this-world.
Sorry Tone. I am not belittling. No-no. It is just that this phase change line is a place of any factor slight changing can slip, tip from sublime to wetting enveloping, to within, and apon solid ground standing firm.
Most folks crave the security of one state versus the seeming unpredictably of edge treading.
Others love to edge tread. Crave it. Cannot get enough of the seeming unpredictability they initiated and feel that they control.
Sigh. Sorry. Five days of nightly random 12 hours of boom-booming, flashing fireworks have our dogs over-medicated loopy; still corners cowering; terrorized. And me thoroughly pissed at the edge treaders who do not have the decency to stone-out, hear, and feel their āfreedomsā quietly decently, in privacy.
At least this year it has been wet, raining enough to be still green and I am not terrorized for our trees being lit-off, burning, early āHarvestedā. Boom, banging calling in that Fourth Horseman for his reaping.
Burning Man involvement should be a choice. Not an imposition.

Ho! I see I should have read the latest āLife Goes On - Summer 2022ā first.
I will ponder deleting my previous here.
Sleep on it, yes.

Mr. Steve, I always like to read your thoughts, it is not to be deleted in any way. A person who deals with technology often gets caught up in his absolute ārightā, but there is always another option, often better.
