About This Video:
I made a volute shaped blower where the housing for the fan is volute shaped, that is to say a widening spiral to test the effectiveness of a one way spinning impeller. The previous blower design is tear drop shaped so that the direction that the fan spins is un important. Also with the previous design the impeller spins one way and then the other as it is powered by a simple string mechanism.
In the new design, a weight was employed in the form of a heavy log attached to the rotor. The top of the rotor is held and the weight spun to create rotation. This method produces less rpm than the original but allows the fan to be spun continuously in one direction only. To compensate for the lower rpm, the fan was doubled in size (from 25 cm to 50 cm) to increase blade tip speed and so air speed.
Now with a fan that spins in one direction only, a housing could be used to take advantage of this fact. A volute is an expanding spiral and housing for fans that are volute shaped help guide the air from the center to the outlet more efficiently than a tear drop shaped one. This was made using mud on the ground as opposed to a clay portable one as it was starting to get too big to transport.
The fan was tested in an iron smelt. Disappointingly, it only produced a bit of iron in the form of much smaller prills than usual due to the low rpm and hence air pressure than the original blower. After some rough calculations from research, this design might become competitive with the original blower if the fan diameter was scaled up to 1m diameter from the original 25 cm diameter fan.
The advantage of this design is that it is simpler and has fewer components than the original as there is no string that needs replacing. The dis advantage is that for it to produce good pressure it's diameter needs to be scaled up to the point where it is no longer compact and portable.
About Primitive Technology:
Primitive technology is a hobby where you build things in the wild completely from scratch using no modern tools or materials. These are the strict rules: If you want a fire, use a fire stick - An axe, pick up a stone and shape it - A hut, build one from trees, mud, rocks etc. The challenge is seeing how far you can go without utilizing modern technology. I do not live in the wild, but enjoy building shelter, tools, and more, only utilizing natural materials. To find specific videos, visit my playlist tab for building videos focused on pyrotechnology, shelter, weapons, food & agriculture, tools & machines, and weaving & fiber.

I tested the idea that some viewers suggested to make the blower hand cranked so that it spun in one direction only and to shape the housing to take advantage of this. It was suggested that even with the hand crank ratio of 1:1, the advantage would be apparent over the original intermittent high rpm blower powered with a string. This blower prototype produced a high volume but low pressure air flow due to the sacrifice of rpm due to the 1:1 ratio. I did some rough calculations after making it and think that if the fan were scaled up to 1m as opposed to the 50 cm fan in the video, it might start to compete with the original blower design for the current rpm. I made a 1 m diameter fan but was unwieldy though it might have worked with more testing, time constraints prevented using it in this project. For now I'll stick to the previous blower design till I can increase the continuous rotation rpm with a durable mechanism. Or test positive displacement bellows and natural draft modes of air supply in up coming projects.

Thank you for showing failures and not just scrapping ideas that didn't work out. To quote one of the masters: "Failure is ALWAYS an option." The only important part of a failure is what you do after, learning from them and trying again is critical. Good ideas don't always pan out and just because something doesn't work doesn't mean it was a bad idea. We should always keep trying new things and learning all we can along the way, be it a failure or a resounding success. Showing projects like these that didn't work out like you hoped is one of the things that makes this channel so great. So, again, thank you.

@@sithlordzach8418 What I was suggesting did have the problem that it was cycling some gas. The bernoulli effect to pull new air in would still mix in some exhaust, so that's not ideal. With a true turbocharger, the exhaust is routed through a turbine, which compresses fresh air intake and pumps the fresh air into the engine. The exhaust is only used for its kinetic energy to drive the turbine. In a simple application, he could route all of the exhaust past a fan (a simple turbine) that drives a secondary intake blower.

I think you should preheat the air that goes into the kiln. E.g. make a ceramic heat cross flow exchanger by layering straws with clay at 90deg and making a cube. One direction = exhaust of fire 1. The 90deg direction - input of the fire 2. That way you can shift your starting point up and essentially recreate a marten's furnace.

A Recuperator should be Way simpler than an Exchanger. Industrial Iron Smelting uses three Stacks that get switched around, but two could be good enough. Ceramic Tiles as the thermal Mass and two Valves to change them between the Intake after the Blower and the Exhaust in Front of the Chimney. Otherwise a big Stack of Tiles that are being fired anyway might work too. If the Chamber for the Firing of the Pottery comes after a Blower and ends in a Chimney you could fill the Chimney with the smelting Mix after the Ceramic is done. (I don’t know how problematic it is to cool it quickly, but simple Balls of low Quality Clay could yield Grog for other Products at least.) Blower -> Burn Chamber -> Pottery Chamber -> Chimney Connect the Blower after the Pottery is done with natural Draft or stock the Burn Chamber trough the Blower. Throw the Charcoal and Iron Oxide in the Chimney. - Mixing the "Ore" Powder with Charcoal Dust for the initial roasting shouldn’t hurt afterwards.

@@primitivetechnology9550 Absolutely love the content --- the time and effort 🥇 I was thinking instead of building a skyscraper for the fire kilns always, the tediousness of getting clay and casting thick deep moulds for kilns, Why not build a groundscraper, build it upside-down. I mean if it's possible to dig an equivalent hole, maybe 50/60cm deep × 20/30cm wide and spare just little effort to add thin lining of clay to it and create 2 side holes, 1 for air intake from the tuyere blower, and the other for exhaust gas. You could mould a lid to yet retain more heat. I believe this system would greatly increase thermal efficiency and heat up better and hotter, as the ground acts as a good insulator to retain heat.

I saw an interesting design for double action bellows from a vid about Indonesian blacksmithing, it consisted of two vertical wooden tubes (bamboo I think) with basically a large feather duster in each one. The bunches of feathers acted like a valve, allowing air to pass as they were lifted and forcing it ahead of them as they were pushed down. With two in operation, being worked alternately, the smith managed to get a pretty steady stream of air .

@Fe7Ace 7 ай бұрын

I also seen a double action bellows design from historical African smelting that worked well, which was two pillows that were kneaded like dough with each hand alternating. Ultimately we know bellows were a winning technology, the catch is bellows would kinda need some sort of animal hide to be practical at this stage right? I'm not sure John could easily introduce those materials to the channel in the same way he has been with other materials.

I think there's major room for improvement in the leaf impeller material. Not only was it flimsy to begin with, but it will crease and weaken further.

@sam23696 7 ай бұрын

I think the primary drawback for this impeller and why leaves are required is the rotation with a counterweight will be unstable. The blade will be making contact with the top and bottom, so a blade material as you describe wont work. It also means the wear on the impeller is much higher then his previous design. So either way he'll need new blades frequently. Easy enough to add new leaves, but still less durable then his last design.
