As somebody who lives totally off-grid, your videos are a treat!
Me and everyone else who lives on our site are busy building all sorts of stuff. The many stoves and heaters will come in handy over the winter, and we're busy building your fantastic 1kw wind turbine to supplement our solar panels now the nights are drawing in.
Bugger the folks who criticise you for laughing like a loon- your style is infectious, and *much* better than the usual dry, stuffy engineering content on here!
All the best to you, from all of us on Oakham camp...
❤️

Well said.
Robert’s videos are priceless!!!!
I'm happy to see that some Brits don't have a 'stiff upper lip' and aren't afraid to laugh without a pint in one hand.
Wait - you can build a wind turbine? Going on my 'to find out about' list!
@@gmr1241
We had to abandon this due to its complexity and our inability to aquire the parts needed. He does however have a few different designs for wind turbines that are more practical, with parts that are much easier to secure, and are less complicated to construct, depending on your level of expertise. You may want to use look into those too...

You are not a moron. You are a creative engineer who is comfortable
thinking outside the box and demonstrating your eyeball engineering.
Thank you for sharing.
Know that the Light of your being is a blessing to everyone on your journey. Shine on
That's not right for anyone to be insulting you. You are a very smart person with a passion that others can't understand. I'm so happy to learn a lot from you. You even teach me how to research. Thank you.
don't worry, he's at exactly the right place on the dunning-kruger graph.
If there is anything I have learned in almost 60 years, it's that ignorant people tend to ridicule all things not understood as their "feel good" defense mechanism. Genius is almost always misunderstood by the common mind, analogous to explaining the economy to an infant. I, as many older and/or properly raised individuals, approach our personal ignorance in a humble and inquisitive way in hopes of replacing our ignorance with something learned and hopefully understood. It's best to realize that they are truly just inquiring in the only crude way that they know how, as long as they are met with a cool head and a correct answer, there is a slight possibility that their ignorance may be extinguished. I am constantly being approached by young co-workers and criticized and rudely questioned "how & why", as if I owe them an explanation for their lack of basic knowledge. 😅 What can we do besides make an attempt to teach them something 🤔
made Rob laugh so let em insult away. if he's a moron, I don't want to be "normal", I'd rather be a moron too..
I think the manic laughter is from some awesome new drug he invented.
Looking forward to that video.... 👍
@@mcnihilation7286 lol
Neat a teeny tiny solo stove. Excellent.
I have to be honest with you Robert. The name for this channel is just GENIUS FOR SURE. Can I say "You are the MAN" !!!!!
With all these peas, potatoes, pies and Paul's biscuits you have the makings of a good start to a bio digester for some additional biogas!
He mentioned a Chili can in one video...
You can bet a lot of people who have an issue with you don’t have a single creative hobby. It’ll be a truly sad day when people stop trying. I love how you do your videos
As a fellow stove designer/maker/tinker... I salute you. Cheers from Sodom and Gomorrah, California. Love your videos so far. Keep them coming.
Your giggling is very much infectious (& dare I say “cute”? Maybe not). It is refreshing to see someone get excited/giddy about something they love to do!
Love your energy and enthusiasm. Thank you
I never thought about a mantles function much before but after learning that the fire will stay within the mantle and you showing us a stainless mesh one I must say that's awesome too! Thanks Robert! You've done it again 👍🏻💪
I have a 44gallon drum version of that down draft gasifier and it's fantastic. Load it up once for the night and enjoy the show with no smoke.
Can we have an upload ?
@@strawman9410 I second that, would love to see it!
I've been without power and other utilities for days, it's best to know as much as you can to survive. Appreciate and respect this gentleman for taking his time and efforts to share his knowledge and thoughts, nobody "owes" you anything in life so at least be thankful.
So easy and effective.
It's like the camping food, comes with its own heater!
A little problem with that idea - you have to eat the food first before you can heat it lol.
@@BenMitro You can't heat the food in the can. The inner wall epoxy liner is not meant to be heated.
@@piconano I didn't know - thanks PicoNano. I could swear I've seen people heating up canned food near the fire after punching a hole in the lid, but that may be just misunderstanding on my part. I've never done it, so I assumed...I guess when you first convert the cans to a gasifier, that lining gets burnt off, but if you set it on the coals with the food in it the offgassing of the liner amalgamates with your food, poisoning you in the process. Possibly just putting a can in a boiling pot would be OK...maybe...doubt it.
Still, I thought it was funny thing to say...and I learnt something, so thanks again.
@@BenMitro Yes. some people do it out of ignorance or not knowing, and get a chuck full of micro plastics in their food.
This is a great small project, I'll totally try this out!
The information and advice you are putting into public information could easily be saving lives this winter as the majority of the phase very little knowledge of how to use traditional heating systems. Thanks for your time to put these informative articles onto UA-cam hopefully we don't need them but better off to be informed.
Phase people sorry for predictive text.
I have met a lot of brilliant folks over the past 52 years . mostly millwrights and alike but you sir are the top 5, Considering your humor into the equation would place you TOP G . stay cool Mate
i had put a comment last week praising your true genuine child-like laugh, i can't but smile when you achieve something of greater value from simple stuff. keep going Robert, whatever some people say
Enjoy every single one of your projects! Keep them coming. Who knew Anthony Hopkins had a genius twin brother?
He also refers to "Rube Goldberg" in one video, but rather his UK cousin.
I enjoy all your videos, but these simple "stuff I got" builds are great. I don't have random motors and chemicals at home, but I do have tin cans :) - off to the garage with a tin of potatoes and some mushy peas. There will be a rush on large tins of potatoes at Asda tomorrow ;)
Robert, I just wanna have as much fun as you do. I happen to have the cans in front of me right now and as soon as I'm finished with this comment, I'm ordering the carbon felt from Amazon. What a blast. ...literally. Many thanks. You bagged another subscriber.
The more dangerous the creation, the more Robert giggles. Love it! My stainless mesh and carbon felt is on its way so I can build that IR heater. Amazing invention. LOL, door open and shop a bit hazy
Nice build, I built one of those several years ago, then crossed the design with a rocket stove. Managed to get the airflow high enough to get a blue flame fom twigs or wooden cat litter pellets (Fuel sources) using convection alone. Admittedly I had to use several tins to make up the chimney to get enough updraft. It gave off so much heat that the the tin cans I used as a fixed chimney (with a few holes drilled in to help with secondary burn) would glow red during daylight! And Almost yellow at night.
So these can generate a LOT of heat if done right..the hard part was trying to make it refillable whilst still lit without obstructing the airflow and gasification process.
It would be interesting to see what other ideas people come up with.
.. My burn time averaged about 20mins. Probably due to increased airflow and heat generated in the system.
Senior year at university we always said. "the smartertyuo get, the more you giggle!" Cheers.
I love your videos , they are so informative and are project's that everyone could achieve
I love the way you're always laughing, you make me so happy and you're smart too.
I just found you the other day and I've been watching all your videos. I find it all so interesting. I'm trying to find a way not to freeze to death this winter. It gets very cold here in Kentucky.
Oh bother 😬
God bless you
Jude, from Kentucky ✝️🐴🐦🌿❣️
I listen partially because of you laugh, it is genuine. I take it that today's gasifier will fit the heater shell you made.
Sweet.
Well Robert, I had to build one and give it a go. It took about 15 minutes to shape the cans by providing holes and then it was ready for its test.
I then shaved a handful of small pieces off a chunk of fire wood and dropped them in the can followed by half a teaspoon of ethanol and a dropped match. Wala, delightful & nothing left but grey ash a few minutes later.
Haha you are a tripper Rob, albeit a smart one and we love you for it. Makes me think you know what's what in this world!
Well, he was wrong about the vaccines, but other than that he's on point!
Robert Keep Laughing!! When we laugh, we learn - FAST Laughter Learning Lingers . Thanks for all you videos
I really like your videos.
They're educational and just fun to watch while still being practical too
Well done
Your laughter makes the videos for me because it shows your delight and enthusiasm in what you are doing.
I wish I could enjoy life as much as you seem to do.
Your videos are very instructive, interesting and enjoyable.
Keep it up, mate 👍👍
Terrific little rocket heater Robert
Thank you Robert for opening doors of knowledge to us all on UA-cam. This is amazing fella. I know you are going in the right direction.
This is a wonderfully simple heating device that can easily pack down inside the can for backpacking. Thank you sir! I will be making 2 of these today.
How did it go? I've been planning on making one for backpacking for months. I'm thinking of one more small can as a 'pot' on top and one more big can as a windshield, but if the pot can was even bigger it would all pack into the pot.
@@tonyrobinson1349 I made mine out of bigger cans. The bottom can is a #10 with a large beans can inside. It makes heat for about 30 mins per load of sticks. I'm tweaking the hole size and spacing to get different effects. Mine are vortex heaters with the fire spinning around like a tornado. I used an awl to bend the edges of the holes all to the side a bit to help direct air into a vortex. I don't think it works any better, but it looks cool. 😁👍
@@shtfengineering7472 I'd like to see how small I can get one. Penny stoves are the smallest I've tried, but they use methanol, which you need to carry when camping, not collect.
You just need to dowse the stove with cool water before you touch or pack it away.
Good sir. As a fellow putterer , tinkerer, fixer, creator and thinker, Your enthusiastic and thought presentation of science, simplicity and inginuity is inspiring. Please keep up the good work and thank you.
Hi Robert, your stove is called a TLUD ( top lit updraft gasifier) This stove will lay the foundation to effectively produce charcoal. Our kilns are based on this concept and bulk produce charcoal. Equally as simple is the charcoal gasifier for engine fuel. Very simple metal bucket with a single nozzle at its bottom. Incorporate a water drip method into the nozzle and you will also produce " water gas" via steam to carbon reformation. You will find this simple gasifier is much easier to operate than a woodgasifier, it will run an engine very stable and without tar.
You are great. I love your stile.
Amazing Videos. Easy to understand for dummies.
Robert, there is an overlooked fuel that people do not think laterally enough to realize is a fuel. I don't know if this is as easily available in the UK as in the US, but here, you can get rather large cans of vegetable shortening for cheap. Walmart has 6 pound tubs of Crisco shortening for $19. The generic brand is even cheaper. On UA-cam, there are videos by survivalist prepper dudes who have made heaters and candles using shortening.
If you use one of your forever wicks and some clever methods to warm up the shortening so it will liquefy, you could very likely use a shortening candle to act as a heater.
Could always use a small amount of alcohol as a starter.
If I remember correctly, you don't have to warm up the solid shortening, just sink a wetted (fuel: old, shortening, paraffin, whatnot) wick down to the bottom of the lard can, and light it.
Like wax, the fire will melt the shortening enough to keep the wick lit.
The mantle containing the flame is where humphrey davey scored with his explosion proof miners lamp...
Nice one...
Dude, you're next level. I just found your channel and i dig your attitude and approach. You seem like a smrt guy to me. Some things require a pragmatic approach and you seem to know when that is. Thanks for cutting to the chase and giving us the practical insights on how to be a survivor in an antagonistic system
Everytime you giggle, I giggle. Love the videos!
You certainly open many doors too different directions and all need exploring lol . That's brilliant and all for a few twigs . Amazing.
I used to burn cat litter pellets in my wood gasifying stove. Worked a treat, but only ever used it outdoors.
Endless supply of ideas, I believe your mantle description is in 1702 instead of 1701, unless it is talked about and I missed. Enjoyed.
That’s absolutely fantastic Mate, ……….”MUM” 😂
I love your videos - you are a genius with your inventions! BUT!!! - Do you think you should mention the risks of carbon monoxide poisoning if using those stoves in a confined space?
Rob you are the single most important teacher I have had. Thank you. I wonder if you could upscale this easily using (well cleaned) paint tins
Well that is a fun project to help offset Natural Gas usage once things hit -50 here in the lovely Great White North of Canada.
What a lovely man you are. I have fond memories of making my first cat can stove, and now think I need to make one of these too for funsies. Cheers.
Wood gasifier stoves are fun to build and easy to use. Just don't be tempted to touch it, unless it is absolutely cool.
That pyrolysis is a Fountain of Wisdom waiting to be discovered. If you know the Art, you'll catch my Drift.
Robert's "I don't know that much" is Humble-speak for "I am smart enough to know how little I know, as compared to what there is to know".
I recall there is a famous quote that says that more eloquently, but it escapes me just now, where is my better half...(wanders off...)
There she is>
"I'm just smart enough to know what it is I don't know and try to learn as I go along and accept that you're going to make mistakes, and there are going to be things that are not going to be perfect."
Ronald D. Moore
😊
Ah, here it is:
“I'm smart enough to know that I'm dumb.”
― Richard Feynman
Or further back in History(I suspect Feynman's inspiration) :
From Wikipedia:
"the Oracle of Delphi, in which the oracle stated something to the effect of "Socrates is the wisest person in Athens."[2] Socrates, believing the oracle but also completely convinced that he knew nothing, was said to have concluded that nobody knew anything, and that he was only wiser than others because he was the only person who recognized his own ignorance."
I totally agree, you are a very smart and interesting man ,you remind me of Joe the gadget man, I always thoroughly enjoy all your videos, many many thanks. Jim from AUSTRALIA.
Generally I find mushy peas provide gassification without any intervening process!
Keep on laughing, mate! I absolutely love your videos!
The concept in this design used to get more air flow to get a proper burn of the gasses could probably be used to improve the heavy oils stove, maybe reverse having the extra air passing from the center of the can. I'll have to try it.
I thoroughly enjoy your youtubes.
I doubt if you can run this inside though without a vent of some sort.
Mate you are no moron but a treasure. Pure brilliance of an inquisitive mind.
This is really great content for my lifestyle.
for the inner container i made the holes do a spiral from the top to the bottom instead of making sets of rings, that way the gasification flame can shift up and down as the fuel is consumed and doing it in a spiral shape makes the flame also become a spiral and maintain shape, i suspect rhe air travels more doing a spiral than simply going up straight, allowing it to mix, heat, capture heat or whatever more efficiently 😎
"Hole!! Ahahahaha!"
This is the kind of technical instructions I need.
Should d it like the Count from Sesame St - "One Hole! Ahahaha! Two Holes, Ahaha!...........SIXTEEN Holes!! AHAHAHA!"
One bloke in a related video recommended that you buy a special set of nippers designed to cut twigs to look like pellets; it was $35 US.
Thanks! Merry Christmas!
Spectacular and easy. I hope you caught my dry humor from yesterday. I did not wish to offend. Was able to find a lot of the parts for that unit at a thrifty shop. Take care, God bless. Apologies were after yesterday's contents. Thank again.
This is awesome! I have a cheap gasification stove I bought on eBay, but to make one so simply and cheaply is just brilliant! Maybe I should make a mantle for the one I have… 👍
Other stoves on YT are complicated to build and operate, and some contain many small bits that can easily be lost. Robert keeps things "stupidly simple," even if you add the mantle or the carbon wick.
I think you are a blast, to watch!!!
I wish I had you as a high school science teacher.
This was quite interesting thank you VERY much! ;)
Well clever, and let's not forget to do this in a room with good ventilation. Those burnt gasses will put you to sleep in an enclosed space.
Thank you, I was always wandering how this thing is working. Keep humor and happiness, you make me happy too.
Brilliant. Thank you....
I like the way you get on with it - It works superbly 👍
Just so people know you can buy very good collapsible camping/home use gasifyer stoves as low as £20.
How long will it burn for from full? This is a great idea for keeping the shed warm.. also if you add more wood will it go Smokey? Great vid 👍
My stove, without the mantle, burned for about 30 minutes, because it was working so well. I used a soup can for the inner chamber.
This is excellent for burning acorns which I have by the billion.
Sometimes you just know you're going to like a channel. It took me 36 seconds of this video, having never heard of you before, to click that subscribe button.
Robert, I have an idea for a variation on the mantle I'd like you to try, to see if it won't result in a significantly improved burn even compared to what you've shown in this video. Make a double mantle: make an inner mantle that's cone-shaped, then make a second mantle on the outside that's the cylinder. The cone shaped mantle forces the combustion gases to slow down at the interface where the flame hits the mantle, and it micro-turbulates the mixture forcing it to burn on the mantle, causing it to really heat up and radiate heat. The second mantle catches the build up of hot gases around the first mantle, and also picks up that heat from the hot gases, and radiates it. Otherwise those gases would simply rise and escape with the heat embodied in those hot gases.
The double mantle idea comes from the Searzall culinary torch, which converts the heat of a torch flame into radiant heat for more even searing and for eliminating "torch taste" from unburned hydrocarbons. I am fairly confident a double mantle, with an inner cone shaped primary mantle, should do the same. Slowing down the gases and micro-turbulating them should improve the efficiency of the burn.
This cone...is it low and dumpy or quite tall and tapered???
Almost the same size as the outside mantle? Or half the height?
I see half height in my minds eye...
something about that gives me a good feeling about natural behaviour of flame and mantle.
Great idea...good thinking.
@@howler6490 I don't know what the optimum shape is, but I would suspect the same height as the outer mantle would be best. Not exactly sure why, just my intuition. I would hope Robert could do a bunch of experiments to see what the effect of various different cone heights would be. Or maybe even put in several cones, and see if the benefits of using a cone mantle that forces the gases through a mesh can be multiplied.
I hope Robert sees this and tries this.
Wood pellets work well in those also
I think your enthusiasm is awesome, never change!
Peas and potatoes? I'm happy to see that you didn't decide on dog food cans!
Fortunately, my neighbor has a dog.
People looking for a fuel source should also research the distilling process. Sugar water yeast and time, then use your heater to produce your next fuel source.
Unless you live in a forest, one cannot assume to have access to wood for very long. Now you can scrap paper, shred it, emulsify it and dry it into logs and bricks but that takes advance preparations.
A piece of tile or ceramic stuff should go under the cans, because they do get quite HOT.
LOVELY DEMO,,.....so happy, like you
Nice. Spin it on a turntable for a lark and get a fire tornado.
made one of these a few years ago a little bigger using coffee cans. The only difference was I cut two L cuts on the opposite sides of the outer can at the bottom instead of holes. that way I had two metal flaps I could bend in so the in coming draft would spin around the combuster making better fuel to air mixing and a more centered flame. wish i knew about the carbon felt then. I would have lined the outer can with it as insulation. The hotter the incoming air the better the gasification. Made a much bigger one out of steel drums as an incinerator. That needed a lid for the combustor with at least a meter high chimney for the best draft. with it cleaned also made an awesome grill.
This insulation idea should be explored.
Best high temp insulation besides vacuum and aerogel, is fumed silica. As it is a loose insulation, you'll need something to contain it. You might be able to use carbon felt, but I think ceramic fiber would be better as it is more dense.
It would run quite well on pieces of that Amazon box, too!
Need a bit of a thought about exhausting the combustion gases without losing all your heat. Perhaps some kind of a window exhaust port. 2.5-5cm steel pipe through some rigid insulation set into a partially open window. Put a potato can through the rigid foam 1st then the exhaust pipe through the center of that. Stuff the can with Roxul or some equivalent insulation to keep the heat from the exhaust pipe from melting the rigid insulation sealing your window. If too much heat going out the window a bit of a serpentine on your exhaust pipe.
Now I aspire to be a moran like you Robert.
Mix peas with ”mashed” potatoes, and finely chopped meat. Really good.
Right I'm off to ASDA for my potato and mushy peas for lunch. Excellent video and very interesting design. So do you think it would scale up ok if I made one from stainless sheet steel?
Then I scraped the soot off the top and made a super capacitor! Lol
Brilliant thanks!
Awesome love it.
I've been wanting to build something like this for a while, but my cans are still sitting on my desk with potatoes in them. I'm working on a stacked design, the bottom is a gasification stove as your video, the top heats my food/water for long distance wild camping. The idea is the burning gasses heat the bottom and sides of a top small can that contains food/water and are also contained by a big can, where the mantle is in your video. I'm now worried by airflow, but there's only one way to find out, and that's to build it. The weight should be a lot less than my current wood stove, so it could really catch on.
Thanks
Love it as always.
2.07 Add sausages and glavey and yer sorted !
Awesome
with a basic concept that... just think, with a few tweaks, you could run a car or power a generator! 😉 I love the super simple design for explaining pyrolysis. 👍
He does have the magnet amplified sterling. And the one he may have invented.
