Primitive Technology: Simplified blower and furnace experiments

- Blower description
The purpose of this project was to test a simplified blower design connected to a furnace. I purposely did this to show that people in most natural environments should be able to replicate this design without difficulty. This blower differed from the previous one in several ways to simplify the construction method.
Firstly, the impellor was simply a stick as a rotor with a 40 cm wide rectangle of bark tied into a split in its end with a bark fibre cordage. A stone with a pit carved into it acted as a socket for the lower half of the rotor to spin in. If spun in the dirt the rotor can drill down and the position of the impellor can reach ground level causing the blades to bump into rocks and dirt. Later, I plastered the stone socket into the ground with mud to hold it securely in position (not shown in the video, just be aware of this solution if the socket shifts around too much).
Secondly, the housing for the blower was made in situ of ordinary mud (dirt and water on site). It was a bit more than 40 cm in internal diameter. The walls of the housing were solid mud and the roof was made of sticks covered with mud. An opening more than half the length of the impellor was left in the roof to remove the impellor for maintenance and to admit air into the blower during operation. In use, the portion of this opening near the front of the blower was covered with a tile. If left opened the blower still worked but covering it improved performance by preventing air escaping near the front. In places where water is not available, a housing shaped pit covered with sticks and dirt might work instead.
Finally, a simple length of cordage was used to drive the rotation of the impellor. This cord was placed in a notch carved into the top of the impellor rotor. The cord was wrapped around the rotor about 2.5 times. During operation the cords were pulled outwards causing the rotation. When fully unwound, the momentum of the impellor then wrapped the cord back around in the other direction. Then the cords were pulled outwards again causing the impellor to spin in the other direction. Note that this is a centrifugal blower with a symmetrical housing, therefore it doesn’t matter whether the fan spins one way or the other (clockwise or anti clockwise), the blower will always suck air in to its open top and force it into the furnace.
This design is easy to make and use. It can be made with minimal materials by unskilled people. The impellor design is simple yet effective. A stick, some bark and lashing of some sort should be available in most areas. The housing being made from mud, is easily sourced also. For the drive mechanism, I chose this method because the first blower I built had too many parts. There was a frame made of wood and vine to hold the rotor in place which kept causing issues with the rotor seizing or jumping out of the socket. Also, the bow that was used to drive the rotor added unnecessary complexity. In the new design, the simple cord in the notch of the rotor did away with the frame and the bow of the old design and the associated difficulties.
Furnace experiments
The blower was used to power a furnace attached to the front of it. Note that with minimal materials, the blower could simply force air into a hole in the base of the furnace and work satisfactorily. But I wanted to test a different configuration so I used clay grate from a previous kiln I made. Fuel in the form of wood and charcoal was used in this furnace by being placed on top of the grate instead of under it. During operation, the blower forced air up through the grate into the burning fuel bed increasing the rate of heat production relative to the use of natural draft (convection) alone.
I made 3 pots and fired them with charcoal. The first pot was painted with iron bacteria (iron oxide being the active ingredient). When fired, the oxide melted slightly showing minimal glazing. The clay became quite hard, possibly stoneware. The second pot was painted with wood ash and placed on a three sided clay plinth to hold the pot in the position of highest temperature in the fuel bed. The pot softened and sagged apart catastrophically. But the ash glaze gave a dark green smooth finish (difficult to see in the video). Finally, a pot was place upside down on the grate and a cylindrical brick made of iron bacteria, charcoal powder and wood ash was put on top of this. The brick melted over the pot, covering it in a viscous blob of slag rather than a thin glaze. On inspection, the slag had 1mm sized spheres of metallic iron in it. Some of these were picked out and stored in a pot. The reason for experiments like these to gain knowledge that might be of practical use in future projects that have not yet been determined.

good thing I found you comment, I was about to write the same thing.

Primitive humans: This is cool.
*Mass production of lead

*Entire civilisation dies of lead poisoning.
"Do not wait to strike til the iron is hot, but make it hot by striking."
That lil nugget was probably just tin.
Next he'll probably strike copper and mix shit together for bronze.
Then comes the iron age.
But if indeed that was iron, then what the fuck
Oh edit; Also slag. tons of slag.
Could you note the time of your important completions in captions or description, please? (I’d want to know how much time it took to have such results of your experiments)

"How old is it?"
"Erm... About three weeks... wtf?"
Eric Wright lmao
Eric Wright so archeologists will question "how is it possible that a human being could recreate an ancient technology after several millenials?!"
If my life turns wrong and I become homeless, I want to live out in the woods with this guy. He seems like he knows what he doing.
morgan girardin
He said he has military training and knows most of this from internet, he surely knows what he's doing
Eridan 24 according to his RUclips page so do sent he have any military training. That just makes this so much more impressive.
morgan girardin I hate seeing all the new fans comments.
Well he is not living continuously like this! So you are out of luck, he is doing these just as projects. If you are in danger of going homeless seek help from your friends, community, government. Don't do foolish things!
Maybe its a good time to put some money on BITCOINS!
Ash Westbrook Well you were once a new subscriber. So you cant say shit.
This is basically the closest thing we've got to a Dr.Stone live action
I bet almost anything this is what Dr. Stone is based off of
@@valthiriansunstrider2540 agreed
I know right
old comment but one of the problems he seemed to have when trying to make iron is the poor quality ore. to not use excessive ammounts he might try panning to concentrate the heavier ore from the lighter silicates. when he tried to make iron he only got some small iron prills out of it.
I'm pretty sure Dr Stone is based off of this. Both are amazing though.
Thank you for the long and wonderfully detailed descriptions, especially in this video. I had no idea wtf was going on lol. After reading though, this is super interesting! Thank you for all your hard work you put into every video, I really enjoy watching them!

do you mean iron age or electric guitars?
Fuck I can't wait for him to get to 2018 and hit minecraft age lolz
This guy is basically bypassing bronze age..

watch him advance in technlogies beyond our current
I could imagine someone coming across this and thinking "wow this must be 1000s of years old!"
Pro tip:
If you put pieces of straw to your clay it will leave air hole that will allow clay to expand uppon heat.
Like so he can see.
Altho... i dont know if you'll need it since you will progress to industrial age in next 5 episode's

Only just recently found ypur channel like maybe 4 days ago and i have binge watched all but maybe 2 videos. Its amazing to see how it started and watching it progress and i can't wait to see where and how you continue to develop the tools and contraptions you use!
I always forget about the subtitles and then watch the video again.
AgentMCCityDE What, subtitles? I didn't that! Lol
AgentMCCityDE i did not knew these videos have subtitles xd! thanls lol
Lol, I thought I was the only one who watched it twice. What got me was when he was picking the little beads, like wtf is he doing. Lol
Oh my fucking god I actually never knew the vids had subtitles!!!
AgentMCCityDE OMG i need to watch every video again
Scrapes off a bead of iron.
And so it begins.
In the next episode: a sligshot that projects little iron balls.
I wish you good fortune in the wars to come
So this guy is the living evolution
In the next episode: A 12-gauge shotgun feat. bird shot
Collab with the Slingshot Channel?
Upon seeing your stoves/ovens... The best one is the rocket stove type wherein you made the roof tiles.
It burns to high temperature; retains heat; can cook on it; can make potteries and metallic items (knife and chisel).
You didn't need to continually blow air to maintain high heat; it basically feed itself air... all you need to feed it is wood.
It’s my theory that this guy directly inspired Dr. Stone
This guy inspired a lot of copycats, and popularized the genre.
Im pretty sure Dr Stone was heavily inspired from Primitive Technology. Both are awesome though.
No you're wrong Dr. Stone was inspired by this guy.

This man make mud better than anyone I have ever seen in my life.
It just amazes me how hundreds of thousands of years ago some people had to literally discover and invent this stuff, and now thanks to this silent, shirtless and barefoot guy (sometimes with sandals) we can see everything from our home. Humans, hey!
he's finally moving on to iron guys
Simon Smith no he's not, read the description.
400 subs without videos white supremacist
It says he's just experimenting, but he has collected Iron pieces, so yes he can move to Iron if he wanted to.
I feel like I'm watching a very slow real life version of Minecraft. Just waiting for him to discover and smelt diamond so he can start blinging himself out
He will reach interstellar travel before us
This really reflects a rapidly advancing stone-age civilization. Whereas glaze experiments like this, in a more slowly advancing civilization, would involve more carefully crafted toolery, this uses much more quickly cobbled together tools to achieve a very similar effect. Truly impressive, this is developing very quickly.
Him as a kid:is playing minecraft
Mom:go play outside honey

This is the best video yet. Love to see you try and adapt
When primitive tech uploads it's a special day
Great work! I love how you have done started to develop glazes for your pots. Just a tip from a potter, if you want to make your clay high fire you could try to find some quarts rock and crush it and add it to the clay. This would increase the silica content (Silica has a very high melting point) so it could keep your pottery from melting at stoneware temperatures. :)
This helped my bushcraft setup
seems notable
notated !! I have plenty of clear and white quartz . Also have a high amount of grey clay. I plan on making my own concrete. Just am lazy and purchased bags of limestone tho. lol
When I grow up, I can do whatever I want; I want to play with mud. And so, he followed his dreams.
I don't know why but his videos calms me.
you know its a good day when primitive technology uploads a video.
Yes, he is about to enter the metal age in this video !
The only thing that he needs now is the iron ore stones. The mud that he got is not good enough.
Sometimes you see natural iron ore that is rusting away in the rivers, he needs to find that one.
The orange mud is, I believe, just like bog ore and essentially what most Greenland or Icelandic Viking iron was gleaned from. Thinking it does not rust like that made from hematite or magnetite either and comes out blacker depending on manganese and magnesium content...
He is skipping the bronze age and going right into iron age!
What metal did the vikings use lol they just had cloth and beat each other with sticks
Perhaps in Queensland they have no copper or tin deposits?
You are right, I gave him a suggestion to use the carbon from the charcoal to remove impurities from the iron. He will go into the steel age after the initial experiments.
He can always refine iron, when he collects enough.
Iron and steel are also simple to recycle. Unlike broken clay or damaged wood.
Anyone think this should be a lesson in school about actual survival skills? Not fricking algebra. This is important! I've learnt so much from his videos.

His goal was never to progress. He merely creates and showcases primitive technologies. He has no need to "reach" technologies of further ages, and those are not his specialty.

Achievement unlocked: Accidentally refine iron.
He may just have accidentally recreated the birth of the Iron age!
Well it is very likely that metals were discovered making pottery, imagine using tin or lesser metal holding stones to build the kiln as a short cut (or simply to build a larger one) to not having to use that much mud/clay. Then it's entirely likely the metals that melt at lower temperature would just 'poor' out of the wall...

Doctor Wrecks that was definitively not accidental. He has been working on this for a while.

Might be interesting to see variation of the blower that could be powered by a water wheel at the creek, allowing it to have a more consistent flow of air and allowing you to fire pieces without having to be spinning the blower yourself the entire time.
Great video as always :)
Thanks.
I had the same thought initially, but that would be quite the mammoth undertaking. Just getting the framework up and stable would be work enough, he'd presumably have to use wood to fashion the cogs/gears, which I suspect with his primitive tools would take many days for a single cog.
Give him time :)
Or just make a handcrank so he can fan continuously instead of in puffs
Cogs and gears would be no more effective than a pulley system, which I think would be a lot easier to build and repair.
I was thinking more along the lines of a direct drive from a paddle wheel to the blower fan, which would require no gears or pulleys or anything fancy. I'm sure it would be tricky to do, but I highly doubt it's beyond his abilities with what he has to work with.
I can imagine myself using this after an apocalypse.
