@joshuadelisle. Joshua, this is just one of those areas that I am totally useless within and so I really don't even try as I'd just make a complete mess, but that said I do enjoy watching other people give it a go especially when they endup being surprised by the results 😊. On a different note I have a drum sander with a little problem and was hoping to get your help with the fixing of it, obviously I would pay you for the work done. Just to give you context I'm a disabled person who is just starting on a woodworking journey as I don't have any experience in the woodworking area and with the help of KZbin I'm looking forward to learning something new. The problem is simply that I have broken a number of teeth off a plastic cog that operates the drum sander conveyer bed. I had contacted the company who made it but they don't ship anything to other countries, so basically, no go for getting a replacement part but that said I hoped that it was possible to recreate the part from someone stronger. Hopefully I will hear back from you. 👍

[@joshuadelisle]

@@simonr6793 hi. Thank you. The truth is I have no idea what I'm doing either but I always give it a go as learn so much that way. Regarding you cog, if you can email me (in bio) I'll see what I can do for you. I've got a CNC router to test out soon so that maybe a good project to test out. Cheers J

[@seanthemighty]

Couldn’t you just use gears to increase the torque, that way you can use your existing torque gauge. Will need to do some math based on the speed/ratio, but the gearing is something you can print out

[@OriginalPuppetMuncher]

one small thing I think that will increase the effectiveness of all your turbines is that you need to account for exit flow from the buckets, from a fluid dynamics prespective youre effectively filling the buckets and then trapping compressed air/water in them, so by the time they are back in line of the high pressure supply, theyre more or less treated as a smaller vessel for the energy input, best shown by the pelton turbine buckets, you can see the the curvature of the interior of the bucket to allow inflow and then outflow in the opposite and slightly perpandicular direction to evacute the bucket for the next pass. as always though, love the videos!

[@joshuadelisle]

Thank you. I'll definitely consider that for the next design. Cheers J

[@charetjc]

I'm curious why centrifugal forces don't carry the water/air out of the buckets as it revolves away from the nozzle and empty the buckets. Perhaps this is a problem when multiple nozzles are used with a single turbine. I do think the pelton buckets do a good job diverting the water/air out of the bucket so that it doesn't push against the next bucket as it rebounds, and slow the turbine.

[@joshuadelisle]

@@charetjc There is deffinately something in that. the other thing is the buckets that hold water for longer carry the momentum of inertia for longer so its a ballance I think. cheers J

[@OriginalPuppetMuncher]

@@charetjc Joshua is correct, due to the curvature of the buckets it increases the amount of energy transfer by redirecting the water away, the issue with standard buckets is more a matter of the proceeding bucket being slowed down due to the previous' contents, as the centrifugal forces, does force the water out of the bucket, which is a loss of energy by itself, but also likely collides with the next bucket, removing even more energy from the turbine. So by the time the water/steam has passed through the entire turbine, though a large amount of its energy has been delivered to the turbine, a significant portion of it has either been lost due to centrifugal forces throwing it away so to speak, or the competing force of colliding with the back side of the bucket when trying to leave the turbine.

[@Dmitri_Schrama]

Yes and this.

[@Edgunsuk]

I have an electrician friend that put a turbine on the stream runs through his farm runs the entire thing , hes only like 30 miles from you :)

[@Alexander_Sannikov]

that multi-staged radial turbine is amazing, i have never seen this design before.

[@joshuadelisle]

Thank you. It's used in the power grid but I think there are issues with my design so there is too much back pressure. Cheers J

[@martinhertsius9282]

I think you have misunderstood how the multistage turbine works. The flow should be in the opposite direction; from the inside and out. This makes the area larger for every stage, which is required when the steam expands. Edit: However, since there is really no expansion with compressed air after it has left the nozzle, I don't think you will gain anything for now anyway. You need steam and a sealed inlet at the center.

[@joshuadelisle]

Thank you I'll give it some thought. Cheers J

[@nigelfenlon9035]

This is a great project. I can't wait to see this progress. I do a lot of 3d printing myself (fdm) I love the idea of resin printing due to its high detail and strength. There's an American guy who I saw firstly building his own power generator windmill but more on point he's used similar turbine ideas to use the stream on his property to generate electricity I'll look up his channel and come back to you with his name just to give you some ideas. Good luck

[@broder1929]

Fantastic as always - some ideas- 1- look at Koenigsegg turbo- built in ONE RUN- they did compressor and housing at same time- built around the bearings-might be able to do same? 2- watch a turbo being balanced -extremely small tolerance -your black tape needs a twin 3-without a housing, your tests aren't realistic - saw video with and without,major difference 4-how about doing a scale model of turbine on TURBINIA -i imagine that as it's in public domain, there will be drawing or even a model somewhere,that can be copied ? With 31 discs, would throw out great efficiency 5- put a clear plastic sheet of decent thickness between you and testbed- protection against exploding disc,and stops water landing on live handtool KEEP UP THE GOOO WORK !!👍👍👍😁

[@david-jr5fn]

You can make a turbine probably just as efficient by drilling holes at a tangent around a disc of your preferred material, would be stronger then a 3d printed turbine also and better able to withstand high temperature

[@joshuadelisle]

I'll give that a go for sure. Good idea for simplicity sake even if it's 30% less efficient. Depending on what the eventual most efficient turbine turns out to be you could definitely calculate savings over time to justify a more complex turbine. Cheers J

[@david-jr5fn]

@@joshuadelisle The other suggestion I would make is don't limit yourself to one driving jet, for now yes it makes it easy for testing but when you actually implement it no reason why you can't have three jets, and you can always shut off a jet to play around with optimization

@@david-jr5fn definitely. Cheers J

Just a tip concerning your plan to backyard cast those pieces in aluminum. It's pretty hard to do this right and a long process. You can use a metal 3d printing service like craftcloud so they can print it for you, it will cost a couple hundred bucks and your tolerances will be great. That's a really great series, I await the fully enclosed designs :)

[@joshuadelisle]

Thank you. That would definitely work getting them 3D metal printed however I'll be using the foundry anyway for fun so it will be a good test. I'll also be attempting to design for casting so the process is as smooth as possible. Cheers J

[@nickalfonso8616]

@@joshuadelisle If you plan on doing the castings based on some kind of lost 3d print casting I'll suggest the channel Vegoilguy. He has a lot of interesting videos on the subject that might help you learn more about the process as he did for me. Edit: It also might help to give the turbine more mass as far from the center as possible

[@monkeygjluffy4487]

I've Always wanted to try one thing about steam, if you put a pneumatic drill but you use it as a steam turbine i think colud work probably not very effective and surely Dangerous but i saw online and they cost like 20euro so i think is worth a try, only concern is the grease that maybe isn't the best for steam and make the steam dry to avoid problems.

[@joshuadelisle]

I've actually got 3 to test out. One it 20000rpm, another is 1400rpm and the last is 750rpm. I'll be sure to try it with some steam oil to prevent rusting. Cheers J

[@smoothjamie4046]

There is an easy way to measure power output. Measure open circuit voltage with no load (this is the maximum voltage). Next, short circuit the output using a multimeter in Amps mode. This will give you the maximuk current. The maximum power will then theoretically be P=(VxI)/4.

[@joshuadelisle]

Thank you. Good tip. Cheers J

[@Tattooedfreak]

Make a water wheel if stream on property couple car gear boxes and a massive electric motor. Low gear and the secret is a fluid flywheel in a low gear the power of water when the well balanced mother catches up speed then change gear each time the fluid flywheel will give motor chance to slowly build up speed. Slowly but surly that motor will get to amazing speed. To disconnect drain oil from flywheel

[@monkeygjluffy4487]

Joshua, Kris Harbour Natural Building has gone through a lot of the designs and various evolutions to building this type of turbine for his hydropowered system.

[@joshuadelisle]

Thank you. Possibly however my boiler design is pretty cheap to build and theoretically should still work safely and effectively. Stirling is good but doesn't have the torque compared to steam/hydro. As soon as you add a load you need lots of force to overcome the resistance. Cheers J

DC charging is done by Voltage difference. You're panels are probably pushing 18v in full sun and a fully charged 12v battery reads around 14.4v. If your serious about burning wood for energy. Look up Wood gas or Syn gas. Tons of 'tubes on it and it's much safer than Steam - Boilers do go boom.

Nice. 1968 at school built double cup version and 12v Mabuchi motor genr. Still low power though. How about a Stirling engine?

[@trevorhorton8472]

@@joshuadelisle My turbine had gull wing vanes with support in the centre not outside edges. Torque increases when the turbine goes into the casing as water mass on the downward turn increases the force on the gull wings, however speed reduces due to increased drag. Therefore I had a chain and sprocket to increase speed of the genr. However output wasn't that great.

You cannot get any more power out of your system than you put in. Comparing the pressure washer output (either pump rating or calculated via flow rate and pressure) to the grinder draw would help you determine if its a design problem that could be solved or a inherent limitation of your input

[@ET_AYY_LMAO]

You are only using two of three phases of the generator... You should try to connect a rectifier and a buck converter and then connect it to the battery

[@shadythereok]

I would've done that differently

[@anned8634]

I like the 3D printing idea but what i would do is print it like you but in a material that would cleanly burn away after the part was put in a sand cast mold. I could then cast in aluminum or bronze. I worked with Pelton wheels and i lived about 10 miles from where they were invented in Camptonville, calif. The problem with any type of plastic pelton wheel buckets is any fine sand or clay in the water will cause wear on the material. There is many wheel designs that the buckets can be mounted to that increase the way the pelton. I have seen large wheels with many buckets i have seen wheels with a thick centerwheel that acted as a fly wheel and had a very smooth speed under varying loads. The one i had was about 14 inches dia and ran a 40 volt alternator for charging a battery mine locomotive. I had a 400 foot water head with about 200 psi flow out of two 1/4 inch nozzles to increase the hp of a pelton wheel you just increase the number of nozzles around the wheel.. The water from a cup design can not hit the backside if a cup before it this act as a brake on the system. on a pelton wheel the water hits the double cups and is sprayed to the side.

[@joshuadelisle]

That's very interesting thank you. Cheers J

[@YodaWhat]

*The problem I see with all the buckets is: No proper exhaust path. Flow ends up by hitting the wrong side of the buckets.* The flow redirected by one bucket hits the back of the next bucket, where the desired force generated within the bucket is mostly counteracted by the _still fast-moving_ flow hitting the bucket backside. That means the force you want is mostly cancelled out by the unwanted force. You could solve that by having a *side inlet+side outlet* design with buckets like deep-bowl spoons. Less good: Put the buckets farther apart and give the bucket backs a flow deflector shape to reduce the unwanted force from flow hitting the wrong side of the buckets. In general, you want to design the overall system so that flow exits the turbine at the lowest possible speed, after giving up almost all of the initial kinetic energy. Obviously it cannot be zero speed or the flowing fluid would not get out at all. I cannot be ore specific without knowing the specifications of the generator to be attached. In particular, the torque input needed by the generator at the speed it will produce the desired voltage under expected load. Manufacturer specs should include torque/voltage curves for various output power levels.

[@joshuadelisle]

Thank you. That gives me something to think about for the next design. Cheers J

[@Feral_Sage]

Charge a battery, then use the battery to run devices. This way you arent putting a load on the generator itself.

[@billdoodson4232]

That radial design isn't going to work that way round. There is nowhere for the water to go, you are trying to compress it into a smaller and smaller space. It might work on steam if it comes in from the centre, but you'd need to work out pressure and enthalpy drops as it goes through each set of blades.

[@joshuadelisle]

It may not be clear in the video but it has a fair large exit in the centre. Back pressure could definitely be the problem though. Cheers J

[@johnsnow6012]

have you tested if the motor is giving you ac or dc. all the motors i have used give ac so it then needs a bridge rectifier

[@joshuadelisle]

This one apparently has a built in rectifier but I'm not convinced it's any good. It measures in DC and won't operate the grinder which is AC. Cheers J

[@kameljoe21]

Another channel umm Creative Channel I think made a boiler type thing. What they did was just make a pressure tank and then a small pipe coming out to shoot pressure to a fan thing that moved it an creates energy. While something like this would never be approved for sale or get any type of certification it could be a viable product. We could use wood here to heat and provide energy. I do think a wheel is the right way to go as a steam engine is going to add more friction where the wheel will not. In the Creative Channel design they just had an open fire pit. This works for that. Yet one does need to enclose and contain the fire box and direct the heat exactly where they need it. You will need 2 high pressure release valve one set low and the other set higher. Then you need several valves to release pressure and several water line in puts. Then you need several nozzels. You are going to want several so that way you can build pressure from 100 to 300 psi and have the volume to create energy. Making sure that you have back ups and fail points sorted. Electrionic would be key in allowing a jet nozzle to open when a pressure is reached. For example if you have a full going fire and have six 50 psi nozzles going full blast and the fire burns down and is now only creating 250 psi you will need to cut 2 nozzles till it reaches back to 275psi then you turn one more on making 5 running then when the pressure gets to 325 you turn on the 6th one. At the same time you need to slow the water flow and or increase it. Having too much water in the tank requires more energy to turn it in to steam. This is a flash steam which is kinda what you want. So of those 6 nozzles you have you would have 6 water droppers. When you feed the fire it should increase the pressure and turn the reserve of water in to steam. There is a lot to think about and how to make it efficient. So that it can run more or less untouched for 8 to 12 hours. One should be able to fill the stove box twice a day and the fan should feed the fire to get it going full blast creating heat and energy. Mini power plants that can burn wood, trash, coal, pellets, grains, trash, wood chip, and so on is ideal including adding wind and solar in to the mix as well.

[@DatBoiOrly]

to get more efficiency you need a housing some of the designs shown need those to run correctly

[@joshuadelisle]

Thank you. I'll consider that for the next design. Cheers J

[@rocklover7437]

Two points ... Bristol are fining people for having wood burners and it's only a matter of time before Net Zero outlaws wood burners all over UK . Kris Harbor channel who makes hydro systems has a modified pelton wheel design that is performing better than the original pelton design ,so go check him out .

[@joshuadelisle]

Awesome thank you. How ridiculous is that when lots of our power grid runs off biomass wood chips. Insanity... cheers J

[@oliverer3]

Does the eco flow have maximum power point tracking (MPPT) on it's input? If not I think it will seriously struggle with this input. It also likely has a minimum input voltage you need to hit. A lot of solar panels of that size tend to operate around 30-40V very roughly.

[@joshuadelisle]

I'm pretty sure it has MPPT. There is definitely a minimum I need to hit. Cheers J

[@ndudman8]

Perhaps someone else has already commeted about the solar panels, I couldn't find it in any many/specs, and I don't know the Voc of your panels, which your connecting in series I assume. The unit takes PV upto 1600 W's ? so I'd also guess that it needs more V i.e more than 2 panels in series so that you don't need only full light to start charging.

[@BalticHomesteaders]

I'm so pleased that someone is taking up the baton of trying to make steam derived power from burning wood, something I also have lots of. I've been thinking about steam power generation for quite a while now but all I've seen is people trying to do it with tesla type turbines and none are really conclusive as in they never seem to finish it and actually make electricity that is used to power their home or workshop. As I now live in the middle of a forest wood is everywhere and to my mind steam generation just seems to be an obvious way to go. Really looking forward to this series, and hopefully someday soon having a go myself! Thanks.

[@joshuadelisle]

Thank you. It's proving to be a challenge but I'll get there. The best way is using wood gasification to run a generator but I want to complete the steam challenge first. Cheers J

[@mhdm]

Knowing small wind turbines, I'm pretty sure yours is NOT 240V/mains! The motor is a brushless 3 phase, 3 wire motor. As it spins it will produce an AC sinusoidal voltage on each wire, all 120deg out of phase from one another. Connecting 2 of those phases to a mains powered tool (like you've tried) will not work because the load is unbalanced. What you're missing is a motor controller that converts the 3 phase power into easily usable 12 or 24 DC voltage. Search "wind turbine controller 12/24v" and you'll find some for about 20 quid with 3 connections for your turbine motor and 2 wires for a (car) battery. Put a watt meter in between the turbine motor controller and a (~half charged) battery to measure produced power. The turbine controller automatically sets the load on the turbine to not stall it. Some controllers are MPPT (maximum power point tracking) while the cheapest controllers probably just have a set load curve and lower max power. As you'll be under 300W generated, either should work ok for testing turbine designs.

[@joshuadelisle]

So the turbine has a built in rectifier which means it is DC with only two wires. The charge controller is MPPT on the Ecoflow. I'm going to be switching it anyway to something else. Cheers J

[@mhdm]

@@joshuadelisle If it has its own DC rectifier that must mean it is indeed (supposed to work at) 12V and all you need is to wire it to a (car) battery. With a watt meter in between(/at minimum an amp meter) you can see(/calculate) how much power the turbine can deliver into the battery. The battery absorbs all the power above battery voltage (~12V), which is why it shouldn't be fully charged and the amperage should be kept within battery limits. An alternative load would be the cheapest 220v 600W "travel water heater", the kind that's just a coil you put in water, as internally it should be just a ~80 Ω resistor (600W ~= 2.73A * 220V ~= 2.73^2 A * 80Ω). Resistors work the same for both AC and DC and ~80 ohm should be high enough impedance to not stall the turbine.

[@Ohhelmno]

Idk I feel like there’s a lot of issues with air rebounding in some of these designs, especially with the flat walls of the turbine giving the air nowhere to escape from obviously collects more of the air but it also pushes a lot of the air straight back at the next scoop in the line slowing it down. I think some proper thought into efficiently capturing the air but also letting it escape without pushing back on the next scoop would help tremendously. Although I’m sure for a small scale project like this it’s not the end of the world and is probably only a few percentage points of efficiency but just something I noticed. It might help to flair the sides out ever so slightly.

[@SnowingNapalm]

I believe you need a flywheel or battery of some sort to balance the load to store the power in before being stepped up to charge your ecoflow battery... a capacitor maybe? Also water has more mass than air so can carry more energy through equal velocity unless you're doing a sealed system in which case the air pressure or water pressure wouldn't be escaping the system but simply pushed to the other side... look up hydrostatic transmissions and hydraulics it's a fascinating science

Multistage turbine will only work with lots of kinetic energy on input. Air just does not have it, steam does.

[@EndroEndro]

you need diode for sure to prevent electricity from going back on that electric dc motor

Hello there sir...ive tried about 150 diff prototypes of different turbines and best one worked way simple....try this...2 discs about 30 cm in diameter and 2 cm apart...then inside 8 vanes curved as disc angle go...overlapping othen 3 cm...and inline 2.5 cm inside from outside...you will be amazed how well it performes. Cheers from Ukraine

[@joshuadelisle]

Thank you so much that's great information. Can I ask what is your power source, is it steam or hydro and what pressure? what size generator is it powering and what kind of output does it have? All the very best. Cheers J

[@MattsHomeMade]

When testing you need to test under load to find the best turbine. For each turbine i would suggest varying the load for a given input and finding the load that gives peak power. The multi stage turbine maybe slower but generating much more torque than the others.

[@joshuadelisle]

Very good point. Cheers J

This. This is what another youtuber called Tom Stanton did for his pelton wheel air turbine and it is immensely important. Balancing the load so you get the highest efficiency does wonders

Solar is the way to go even in your darker climate. You can get used commercial panels that are very affordable. Fabricate a large steel ground mount with proper tilt angle. EG4 hybrid inviter and batteries. Solar is static system set it and forget it.

[@joshuadelisle]

I'm not convinced. I've had solar panels for a few years now, some have gotten broken and no idea why and very disappointed they don't recycle them. The commercial ones your getting is so they don't have to deal with the disposal so they can claim zero waste otherwise they would be hit with a large carbon tax for the disposal. It's all very dodgy if you ask me. Cheers J

[@AllAroundTube50]

"Batteries are no good for the planet" - sure, but oil and coal are far worse, so unless you plan to go back to the dark ages, batteries for the win (and the technology will only continue to improve)!

[@joshuadelisle]

I'm not convinced. A diesel engine is easily recycled and can run on bio diesel. Batteries use rare earth minerals some of which are extracted in very damaging ways, they're not easily recycled and the carbon footprint of the manufacture and end of life recycling doesn't match what they 'prevent' using. The grid to charge them is still heavily carbon based and nuclear has a much worse waste coming out of it. Carbon dioxide is excellent for plants but we don't seem to want to grow more instead we're littering the countryside with solar panels that can't be recycled and use fossil fuels to manufacture. I think it's wise to do a bit of research rather than trust papers that were funded by dodgy corporations. The data they're showing doesn't account for the earlier figures in fossil records, for example there are temperate climates tree and shrub fossils in Iceland which had to have been much hotter than it is today for a long period of time indicating climate change is a natural cycle. Overall I just want to be off grid and away from the global madness. Cheers J

[@ghrrum]

Thought of an additional confounding factor. Your turbine is (and should) be enclosed in a housing, that is going to greatly change how the stuff making it moves interacts with it.

Are the resin containers for that HeyGears printer user refillable or do they have to be purchased from them every time they run out?

​@@BRUXXUSapparently I'm mistaken. Unfortunately you cannot put in custom settings for other resins and so you can only use Heygears own resin. I'm a bit disappointed as I guess you are too. I think they should reconsider it otherwise it'll put off a lot of people. Cheers J

[@BRUXXUS]

@@joshuadelisle Aww, what a shame. I'm guessing each container is chipped, or has a QR code that won't let the machine use it longer than as much resin it can hold. There's better options at a fraction of the price that don't require paying for overpriced resin so a company can lock you into their ecosystem. What's worse is, as soon as they stop supporting/selling those DRM resin containers, that whole printer becomes landfill.

[@joshuadelisle]

@@BRUXXUS you might be right. I've re used the resin bottles whilst getting the residue out of the main tray and switching resin types. I don't think they're bar coded but apparently the settings that I thought you could change in their software can't be changed and only matches the resin that they stock. It does make the whole system easy to use with built-in pre sets and the resin is very good quality and specific for engineering applications but monopolization is always disappointing...

[@Enjoymentboy]

My first thought was that the turbine is far too small in diameter. I was thinking of maybe 24-28" (like a bicycle rim). that would essentially change the gear ratio increasing the torque output. But then again what do I know? lol And it made me laugh when you mentioned doing a video on using pop bottles for your FMD printing as I al literally, right now at this moment, running my first print after converting/modding/upgrading an MP mini select to dedicated PET bottle filament printing. Can't say if I'm doing it right but slow and hot appears to be the way to go. 20mm/s at 248° and it is coming out crystal clear and smooth as glass.
