Woodgas Gasifier, Home grown energy. A quick look at how it works. video 4

Part 4 in the series. Ive got gas -Now what? What did I get wrong on my machine? How will I fix it? Wood gas has a proven track record and a150 year history. It is much safer than steam, hydrogen or Lithium batteries. It is possible to build a gasifier without welding or to build one from junk. There is endless help available at www.driveonwood.com forum from people who have been doing it for two decades. The fuel grows in your garden. If you enjoy this content or appreciate the tips and tricks, hacks and DIY you can 'buy me a coffee' on this website. www.buymeacoffee.com/tinyhous... It helps me keep bringing you these videos.

nothings free. wood collecting, wood cutting, feeding the unit, cleaning the unit etc etc. Like what you did here. Thanks for spreading the info. sadly we may need it soon

[@landraver90]

Ingenious! Great work, look forward to the next instalment 👍

[@t.h.o.r.]

Coming soon!

Generating gas to then burn in petrol engines, i feel, is really complex. I like your research, and if you develop a simplified module It will encourage me to build !!! What about using steam for a piston/ turbine engine ? This could just be a universal agricultural engine - it could be just connected to to what you need. No need for oil, plugs and other maintenance on all the other engines. There must be a simplified boiler design out there....

[@t.h.o.r.]

steam is too dangerous- Ill not play with steam.

[@cetate93]

Steam engines still requires lubricants, turbines as well. Steam engines use a very specific type of oil as well. Gasifiers aren't for everyone, just those willing to put in the effort to keep the lights on or the wheels turning.

[@t.h.o.r.]

@@cetate93 The reason Im taking this so seriously, is because here at least in NZ. We have a precarious dependence and supply on petroleum. We no longer have a refinery or extraction facilities. It has all been systematically removed by stealth over the last 15 years. When the inevitable happens overseas and the boats stop coming here. We are STUFFED. I want people to be ready. There's loads of people with the skills and resources to build these. I want people to just copy what works and build something for themselves. these are pretty safe if used responsibly and always outside. They are proven and kept wartime economies moving in europe during the war years. But running one will introduce a new level to motoring skills- ha ha.

Good information cheers Graham

[@joshuadelisle]

Nice. Well done 👍

[@t.h.o.r.]

Thanks Josh- Im itching to get back into some more testing on it but farm chores are taking priority. Its time you got back into this its been 3 months!

[@joshuadelisle]

@@t.h.o.r. yes I've been super busy with my newborn 4th child making sure my wife is fully supported, I've been suffering with hooping cough and catching up on commissioned work. I've been filming 3 videos at the same time unrelated to the gasifier but I've got lots of that to come. I'm going to build a charcoal one at some point to power a motorcycle but this current one I want to use to make the charcoal as well as produce some energy. I loved your build, it's smart and cost effective. I look forward to seeing how much power it will generate for you. Cheers J

[@rossinnz]

Good one mate. Cheers.

[@louisstone4778]

I've been trying to get a wood gas

[@ianmalcolm4731]

Thanks for your info and ongoing efforts!… I’m really enjoying your engineering channel full of great ideas. I’m on the road atm. But intend to learn some new welding techniques ( after 60 years) and have a go at this one….. the beauty is it is built on a shoestring! Thanks Graeme/Graham Cheers from over the ditch Ian

[@t.h.o.r.]

Haha. Aussie Nurse flipper is Graham- Im Stu. thanks for your praise

[@templar1694]

If you live in a rural area and you know how to produce woodgas. And know how to use that gas to fuel a generator. Then you can survive this world.

[@templar1694]

A stirling engine will also be good.

[@Blxz]

Looks like a bit of fun. With regards to your collander, isn't it going to be too perishable and require too much replacing over x number of burn hours? Wouldn't you be better set using something like a solid metal ash plate either home made from solid steel or easily sourced as parts from a Raeburn oven manufacturer? That would extend the lifespan to thousands of hours and mean that you don't need to pull anything apart to replace what appears to be the weakest link in the chain.

[@t.h.o.r.]

Thats what I thought too may people are using s/steel mixing bowls- only a handful seem to use actual grates- what burns out is the nozzle - some people are using tungsten!! mine is ceramic and they cost $4 each. other peoples ceramic nozzles are lasting 200 hours. thats why I went with it - heavy steel nozzles last 150 hours. the old school ones were cast iron. they are the main consumable. the burn chamber eventually burns out in steel ones but Im hoping that my fire brick mix 100mm thick lined with a sacrificial teracotta pot will work well.

[@Blxz]

@@t.h.o.r. You've certainly put a lot of thought into it all. Very impressive. Looking forward to more videos with it working while you run a generator. Power is the only thing I am dependent on at this stage on my property and is proving to be a large final hurdle. A woodgas generator would be an amazing final solution to fully wean off the grid.

[@ironhorse4206]

Have you achieved a clean blue flame?

[@t.h.o.r.]

Ive made changes- but not tested them yet. Keep an eye out for the video in a few days

[@gipsyiloveu]

Do you sell this device?

[@t.h.o.r.]

by watching the video, you will see that Im learning about it and sharing what I learn. I think this is very valuable 'preptech'

[@mattwernecke2342]

How much gas can rhat produce?

[@t.h.o.r.]

enough to run a engine to 30hp- the production is controlled by the size of the orifice. This is 100mm. 200mm will run a V8 but of course it will consume fuel faster

[@craigsaunders7037]

Your fuel is charcoal? Charcoal is just carbon. When you burn carbon you end up with carbon dioxide. Carbon dioxide is non combustible. The only way you can get combustible gasses is from wood which is made up of hydrocarbons and carbon. Adding water to forn hydrogen? Dissasociating the hydrogen from oxygen in your fire is not going to happen. All you will make is steam. What sort of quackery are you peddling?

[@dennisolsson3119]

Coal that burns incompletely produces carbon monoxide. It is the main reason you shouldn't run a coal grill inside afaik. And steam (so: water) is used while burning coal to create water gas. Or am I missing something in your complaints?

[@craigsaunders7037]

@@dennisolsson3119 So you're making producer gas or water gas or some combination of both. Where are we getting all of this charcoal from? Is it waist product from another process? If you have to make charcoal to run this you're missing out on all the potential better fuels obtainable from wood. The original tech used coke or coal, probably for good reason.

[@dennisolsson3119]

@@craigsaunders7037 now that is reasoning I can't argue with! :) I think he (or someone else) mentioned that it was much easier to maintain a stable production with coal. But this might be a false memory. But as you say there is energy potentially wasted unless the charcoal production uses those gasses. Like making the charcoal in the regular stove while heating the house.

[@craigsaunders7037]

@@dennisolsson3119 I just have the idea that you may have this backwards. Wouldn't it be better to use a small charcoal fire to heat hardwood that's in an airtight sealed container to make hydrocarbons to fuel a generator? The charcoal produced by this could be used to run the system and excess charcoal used for home heating. My reasoning is that if you're using a combustion stove for home heating, the best part is after the volatiles are gone and the charcoal is burning. If you're making lots of charcoal instead of ash, something is wrong. Adding charcoal to a combustion stove possess no problems. If you're looking at a wholistic energy approach for households between electricity production and heating requirements where hardwood is the energy source, is it easier and more efficient to make electricity using volatiles with charcoal for heating as a byproduct than the other way around?

[@t.h.o.r.]

seems that you have had way too much indoctrination. Listen to yourself. Then ask: Is this guy doing this or not? is there a propane bottle hidden inside? am I just a know it all blowarse who is completely wrong? Please, learn about the subject before preaching the subject. www.drivonwood.com

I am about to say something but I will keep my mouth shut. More powers to you!
