@@gogutzy I mean, It would give reason for places that always have yearly forest fires to actually manage the forest properly. Since they could use the trees they take out as a source of revenue. Alot of places that have forest fires yearly loose thousands of acres of trees. It would also mean that there would be a need for tree farms as well, and its not just trees that can be sued in the gasifires, you can use dried grass as well. We already make grass pelts as animal feed, it could be used as fuel as well. Also I always see tones of adds for free wood that people just want to get rid of all the time.
@@ryunokurayami2845 ... I agree... What a beautiful car ...a classic... Also a beautiful gasification unit, but what a lot to pull behind you....STAND STRONG. FEBRUARY 2021....🛡🏹🇬🇧 💉💩😠👹
@@thefreeradical2320 Well over time we would naturally find a way to make the units smaller and just as if not more efficient. When there is a strong pull to something more and more inventors will see the need in the market and will inovate it. As a start I could see some units being placed on trucks since they have the cappacity in the bed to carry them. which will then lead to smaller units being created for commuter cars as vans. There is also other usability for the charcole byproduct that some of the units make. its pretty much unactivated charcole. so it can be used in farming as well as air purification once activated.
@@ryunokurayami2845 You´re right. If these forest would be cleaned up properly of any debris, self-ignition would be not possible. Make pellets for these gasifiers, and you´re way ahead of anyone else.
Fantastic bit of engineering which puts my gasifier to shame! Just when you think you are a reasonably skilled engineer someone comes along like yourself and puts you back in the kindergarten. Best of of luck and thank you for sharing this.
Vesa voce vende livros para aprender a construir o gaseificador moro no BRASIL e aqui temos muito residuos vegetais pois em pais tropical o cescimento e rapido de árvores e temos muita poda de galhos de arvores.
what an awesome build. quite some nifty automation. I am interested in running generators with woodgas. I was wondering: is it more efficient to use a gasifier, produce gas and run a generator with it or use the same wood fuel to burn in a furnace (rocket stove type) and produce high pressure steam that runs a steam entine to power a generator? thanks
Just another thought, what if this was used in combination with a electric car. For short trips of say 30 miles you use electric car by itself, for longer trips a electric generator in trailer will run the car till wood burns out and you still have 30 miles of electric to get more wood.
Yes, this would be very interesting opportunity. That way it might be relatively simple, because you would have the electric car untouched and would only generate power for it on trailer. Especially in city trafic this would also improve efficiency. Hybrid cars tend to be more complex. I'm expecting some special knowledge would be needed to change the fuel and to control charging of the batteries..
Vesa, your gasification units look very beautiful! Is this something you have purchased or do you manufacture them? Very few gasification units of this size would be capable of producing enough fuel for such a large engine. What is your fuel consumption to travel distance ratio? (km/kg).
Fuel demand is about 50 kg wood dry matter per 100 km (2 km/kg). In short distances the fuel consumption is still higher. Fuel demand is mainly dependant on the car and the drag drag of the trailer.
That starts with a glow plug, What kind of glow plug is used, I,m starting to build a Gasifier Now, Is there any chance of plans, for the one you have here, Thanks Beautiful Build.
Sure it was on wood gas. As you see on the video, there was quite thorough venting of the system before that. If there is gas in the pipes, starting of the engine is not difficult. Instead of a long start, more typical problem is that because of extra ignition advance starter cannot crank the engine at all if there is still good mixture in the intake manifold. This is likely to happen after a short stop, not later for example next day.
Unfortunately leaves and garden waste does not suit as fuel. It is possible to use real fuels like wood or peat (sod peat). If you could produce suitable dry briquettes of leaves and grass, may be it would be possible to utilize them as fuel for a wood gas-generator.
I think that 10 kW is too low power request for that big gasifier to run smootly. 7.3 l engine running at 1500 r/min or 1800 r/min sounds better. Lincoln as 400 cid engine.
Extremely interesting, i'm from Spain and knew from this way of powering cars, it was used here many many years ago. It would be interesting to make one but, at least here, laws for cars are VERY complicated and if police stoped you driving a car this way... I guess you'd have bad luck. You're very lucky being able to use it in your country, enjoy it a lot, it looks extremely fun and provides an extremely economic run!
Total independency is an admirable goal. I personally would use wood gas for electricity generator to charge large deep cycle batteries when solar panels won't cut it. For space heating and hot water I would just burn wood. For transportation electric bike, electric moped or electric motorcycle. Battery chainsaw. For car and tractor, straight vegetable oil or biodiesel, preferably done from my own rapeseed. No water closet and water from my own well.
I have built this for my own use and used it to power my car since 2006. Everything is, of course, possible and on my web site there is telephone number....
So... what happens when the battery dies? Seems to me the blower will stop working right? If you want something truly off the grid it needs to be completely manual. I would suggest a flywheel type of mechanical stored energy system as a backup to run the blower. You could run it with a setup like a 18 speed bike hooked up to the flywheel. Also have another small IC that keeps the battery charged that runs off of the gas from the gasifier.
Once the car/generator is running it can be recharged by the alternator. Just like the battery in every ICE car in existence. It seems the blower only needs to be running while the system is heating up (He said 5-10 mins), once the car is running the engine seems to provide enough suction that the blower is no longer needed. So depending on the power of the blower you could potentially run it off the car battery and then let the alternator recharge it once running.
Awesome! now to be able to get in U.S. Is there a size limit on Generator efficiency? Because a unit 1/2 size towed behind a small car like a honda station wagon or even a big motorcycle might make it more appealing. And then to able to power your home with it as a supplement to solar, that would even be better.
With extremely small gas-generators it may turn out difficult to make the fuel flow down smoothly. If car or motorcycle has already originally weak engine, the performance may not meet expectations for daily transportation. There is, however, not any strict limit on the smallest size. Cars with 2 liters engines and motor cycles have been converted successfully to run on wood gas. The smaller the gasifier, the more carefully the fuel has to be produced and it must not contain over size particles. Big gasifiers in turn like to eat coarse fuel to ensure proper penetration of combustion air. Wood gas has also been utilized successfully for power generation. Ekomobiili power process is completely continuous, works on chip type of fuel and yields pretty accurately 1 kWh of electrical power from one kilogram of wood (combustible matter). So you may expect to receive 1 kWh power from 1.2 kg air dry wood chips (humidity max 20 %). This works at its best from 15 to 40 kWe power range but with somewhat coarser chips 100 kW electrical power is available. By-product heat is available as hot water (90 °C) both from the gasification process and from the engine. Because of effective gas cleaning process, engines can be run with minimal maintenance years around the clock with out need for overhaul.
The last version I saw was just a 12" box bolted to the back bumper with a door on it for the wood. Why is this so much more complex, obviously more efficient but still, simplicity would be better I thought. A schematic drawing would be nice too to see your system.
In your design, how hot is the wood gas leaving the point of combustion? And how hot is it before actually entering the engine? If you routed the wood gas through a biomass chamber would it be hot enough to start gasification inside the biomass chamber?
The gas has to reach high enough temperature inside the gasifier to crack the tars. Before the engine wood gas is cooled. Temperature of the gas is about 15 degrees above the out side temperature when it reaches the engine. Cooling is principally done on the trailer but, of cause, it cools the whole way in pipes to the engine
My interpretation of your latter question... I'd say: 55 % of wood heat is utilized per traveled distance, compared to 100 % gasoline baseline - iff I happen to be correct. Let's see. I believe he said 50 kg of burning mass (wood or sod peat) is needed for 100 km of driving with this particular Lincoln car. HEAT OF COMBUSTION Birch (wood used): 4.15 kWh/kg. Gasoline: 43 MJ/kg =11.94 kWh/kg Lincoln Mark5 1979 (motor 400 cubic inch) consumes gasoline about between 13 l/100 km (some guy, best result) and 18.1 l/100 km (combined, specs). 1 liter of gasoline weights about 733 grams. Thus, 13 l weights 13*0.733 = 9.53 kg. Thus, 100 km with gasoline results in 11.94 * 9.53 = 113.78 kWh and 100 km with this wood gas system requires 4.15 * 50 = 207.5 kWh Therefore, 113.78 / 207.5 = 0.548 ~= 55 %. This is heavily dependent on assumed gasoline consumption of 13 l/100 km. For recalulations use: (13*0.733*11.94)/(4.15*50) Or, maybe am I wrong? ='D
