Which model X2 laser engraver slash cutter do you have I can't make up my mind I want one really bad and I want one that can cut plywood so I can make some machine prototypes it doesn't have to be very thick just like what you use there
@@ClownWhisper the xTool D1 40w is my favourite so far but I also reviewed the comgrow Z1 pro 20w which works great too and is far cheaper. I've got more to review shortly. Cheers J
@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 KZhead 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. 👍
@@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
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
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 :)
Wow. You'll have to get me his details so I can see. Cheers J
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!
Thank you. I'll definitely consider that for the next design. Cheers J
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.
@@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
@@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.
Yes and this.
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.
Thank you I'll give it some thought. Cheers J
turbines? unusual ones? yes, please. you've got a subscriber right here.
Thank you. Lots to come. Cheers J
to get more efficiency you need a housing some of the designs shown need those to run correctly
Thank you. I'll consider that for the next design. Cheers J
Joshua De Lisle. Master of some, jack of all. Great video looking forward to the metal foundry and aluminium casting.
Thank you. Me too. Cheers J
You may need a 12v to 12v converter / conditioner to then charge up the Ecoflow unit. They are used in offgrid van / marine applications when chargingbattery banks from 12v / 24v systems. like a Victron Orion unit.
Really looking forward to the rest of this series - awesome content as always 👍
Thank you so much. I'm looking forward to it too. Cheers J
In your future tests, i think you need to have adjustable nozzle holding mechanism, angle is going to matter and each design is going to want different angles. Also, for testing output, i think you want the turbine at normal speed before you turn the load on. This is also more representative of real power usage as loads are cycled.
Very good tips. Cheers J
Yes this
I'd also guess a variable load that charges the batteries, and can be changed.
Nice looking pelton wheel.
Thank you. Cheers J
nice! we need more!
Thank you. Lots to come. Cheers J
I like watching your videos, you have the patience of a Buddhist monk, well done. Thank you for sharing your knowledge and expertise
Thank you. I'm glad you understand how long these things take. weeks of work for 20min video and if it doesnt do well can be a real downer. cheers J
Perfect timing for me. We're looking at a micro-hydro low flow, high pressure setup.
Lots more coming soon. cheers J
Thankyou Joshua for another excellent upload you gave me some very good ideas to work on.👍👍👍
Thank you. Cheers J
@@joshuadelisle Hi Joshua thankyou for your kind reply, I been checking out your channel for over 3 years, you are amazing, Joshua, you asked from your subscribers which I am one of, for some ideas about the tubine, so I have a way of improving it making it work better, and if we can then maybe do some testing, then maybe, we can provide free energy to produce free electricerty to all of the UK ((((( its not totally free but you could say its free for what they have already paid for)))), you will understand when I explain to you, but for now I will say that it is free, and put out of business all these f,,,ed up big companies, so I hope that you don't mind that if I send you a privet email, and hope to link up with you privetly, all the best robert London UK.👍👍👍
@@goldbornmusic2025 I replied to your email. Thank you. Cheers J
@@joshuadelisle Thats amazing hope to speak to you soon thank you.
that multi-staged radial turbine is amazing, i have never seen this design before.
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
I grind my resin 3d print misshapes/support leftovers. Into a powder and use it as a filler for resin casting. For lathe blanks. I do it for people's cursed dice as well and make pencils out of them.
If it's something people are interested in I might dust off the old camera stuff and do a video. Or explain my progress if it's something you want to try?
good idea. If I did a lot of resin pouring I would definitely consider that. Cheers J
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.
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
Good video. Kris Harbour Natural Building has some good DIY turbine building videos btw. I hardly ever use my resin printers because of the smell, mess etc.. but the prints come out so nice don't they.
Yes I've just discovered him. His type may not be suitable for my boiler but we'll see once I've built it. Cheers J
Kris does some amazing projects :)
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.
Yes I'll be testing that in the following videos. Cheers J
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.
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
Love this. hope you get it working. been thiking og this. Im doing the diesel heater stuff this year.. Fun.
Great videos as always Josh👏🏻& loving this new kit you have, the resin printers. 👏🏻👍🏻🇮🇪
Thank you so much. Lots more to come. Cheers J
Awesome testing. 3d printing is amazing... I recently got a FDM printer myself. Fascinating project.
Thank you. Yep I've got lots more on printing coming up. Cheers J
Hi Josh, maybe try securing the blades with printing them using a dovetail securing method (no screws) as used in gas turbines👍🏻
Good idea. cheers J
This could help with the balancing also!
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. I see a lot of things in your design efforts that he went through and threw out but some parts are very similar. Kris is in Wales I believe and has a channel that contains much of what he did in designing and running his Hydro. You might want to contact him and review his videos on his hydropower plants.
Thank you. Yes I'm catching up on his channel now. Cheers J
GREAT VIDEO!! This is the first one I saw from you... and I THINK I'm gonna like this channel :) Can't wait to see the rest of your projects! :D
Thank you so much. I review tools and build stuff with it. I've got more on home energy such as a gasifier and bio digester coming after this project too. Cheers J
Another cracking video, keep it up mate, you're fast becoming on of my favourite YT channels
Thank you so much. Lots and lots to come. Cheers J
23:02 There is no shortage of rain in England, you should make use of it somehow 😂
If I had a land with a stream I would. cheers J
you are so cool and smart
You're very kind. Skills don't require intelligence though just lots of practice. Cheers J
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.
Make a balancer! That would be fun.
It would. Cheers J
It might produce landfill. But at the same time it's creating ideas from yourself that could be seriously viable for the future. Win win in my opinion. Looks a good printer 👍
Depending on the intention it can definitely have long term benefits especially if the resins are strong enough to be the final product, that cuts out other industrial waste that would otherwise happen. I think I'm going to concentrate more on supportless designs to reduce waste. Cheers J
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 !!👍👍👍😁
Thank you, definately points to considder for the next build. cheers J
This is awesome. I've been thinking of sun powered steam generator (rocket stove for night/winter) for this very application. Problem for me so far has been the engineering / safety design requirements. So very much looking forward to your upcoming videos on this! Thank you!!
Thank you. I've got a good idea for the safety aspects, it's not going to be high high pressure compared to a conventional steam engine and will have plenty of pressure release features. Cheers J
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
excellent report and explanation, looking forward to watching more of your videos,, we are off grid in cape Breton Canada, we have a Turgo hydro turbine system, so we are looking at any potential upgrades to get more Kw etc cheers Paul
Fantastic thank you Paul. I'll check out the Turgo design and see what that's like. Cheers J
Multistage turbine will only work with lots of kinetic energy on input. Air just does not have it, steam does.
Oh! Fun fact! You can use air pressure to boil water! So maybe just use a long tube to generate some power!
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
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
@@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
Absolutely love the energy being put into scavenging lost energy (pun intended). If more people were trying to come up with cool and innovative solutions then we'd be in a better place. Top stuff!
Thank you so much. I've lots of ideas that I haven't seen before so hopefully one of them will work well. Cheers J
Great Video... FYI for future data collection, the angle of the air/water needs to be more rigid and repeatable from test to test in order for a relative comparison between the different turbine types to be valid... Keep up the great work... PS: the breaking action of the alternator can be indicative of a shorted output in one or more of the phases...
Thank you so much. I've got lots of alterations and scientific methods for the next tests as well as lots more turbine designs to try out. I'll be changing the alternator too. Cheers J
I would consider mounting the wheel horizontal, then any load on the centre bearings should be reduced. The enclosure would also be horizontal, but until we know your intended final power source any input/output geometry is an assumption. Great subject Joshua, I'm looking forward to the next installment. Thank you so much for posting 👍
Thank you. You're right I need to establish the boiler unit first to figure out flow and pressure and build the turbine to match. Cheers J
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.
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
For electricity from wood, I'd go with a gasifier and ice. Or better yet , thermophotovoltaic cells. No moving parts except coolant pump/fan
You're correct and I'm planning on that also. steam is cool though. cheers J
You will need to think carefully about type of boiler. In the model engineering community there are codes we build to to make sure they don't go bang as that tends to kill people and that may spoil your day. If you wish to avoid complications you can go for a flash boiler. Has the advantage of being made of tube, including copper and because it has a small internal diameter you can get away with thinner walled pipe. Also there is less contained energy so any leak will be a lot less deadly. On the issue of turbines, you are only driving at one point, you could try driving at multiple points. Consumes more steam though, obviously.
Definitely. I think my boiler is classed as a flash boiler and is basically a copper pipe coil with a one way valve. Cheers J
@@joshuadelisle That sounds like a flash boiler. You will need a water feed pump.
@@BensWorkshop you maybe right. I'm hoping a gravity fed tank will produce enough. We'll see in the next tests, it could going back to the drawing board many times. Cheers J
@@joshuadelisle You need to control feed rate of water and overcome the pressure in the flash boiler which I assume you would like over the pressure of gravity. You can get a thousand PSI from a flash boiler too.
For a non expanding fluid stream, the maximum amount of work than can be extracted will be near that of a single turbine. This is as the fluid transfers the majority of it's momentum to the blades so further sections can only recover low amounts of residual power. The multistage design you have might be able to show it's performance better with something like a leaf blower forcing air into the center. If that isn't enough, the change in fluid speed you're expecting for each stage seems rather high, perhaps reduce the aggressiveness of your blades.
Good tip. Thank you
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
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
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
Move the UK to the tropics. Then the solar panels will be in the place they were made for. But for you Brits you'll need cooling. And the Sea'd do that? 🙂 Enjoyed your efforts. Interesting. Thank you. Have a good one Lad.
I may consider it as they're banning wood stoves and apparently you're not allowed to generate your own power then less it's government approved. I'm wondering where we could live that isn't so highly taxed and regulated. Cheers J
As others have said, I think a capacitor (or bank of them) on the output would be a good idea to smooth things over & potentially absorb a bit of the draw spike when you add a load to it. Also, a flywheel couldn't hurt, even though you'd need to wait until you have your steam source in order to find the best mass for it. I'd also be interested in ideas on how to make wood smoke less of a problem. Condenser stack? Giant bong? There must be something that wouldn't upset the council.
Thank you that's great advice. I've thought of modifying mine to have a secondary burn but I'm now thinking of building a designated burner that will be more efficient for power generation. It'll have a secondary burn also, turbulent air mix and will be fully portable as a permanent system isn't allowed without permission. Cheers J
@@joshuadelisle It's really infuriating (no pun intended) that there are rules in place to prevent this kind of thing. Seems as though putting wheels on it should do the job though. I look forward to seeing the effect of the secondary burn & how much soot it can remove.
@@nightcatarts I know it's criminal because it essentially means only corporate companies who have gone through paper work hurdles are then monopolizing it when it could be very low cost or even free. A secondary burn is simple in principle, you just use some of the heat to warm air that is directed just above the flames which reignites any uncombusted gases and hydrocarbons. Most of the time a top down fire method eliminates most smoke anyway as the wood underneath feeds the fire on top the gases it contains instead of going straight out the chimney. All the very best. Cheers J
@@joshuadelisle Yep, same pattern as with everything else that could actually help people; big business gets the breaks & individuals are shut out. Oh, interesting. I'd not heard of top down fires at all but that makes sense.
@@nightcatarts thank you. The top down method is what I use 90% of the time, it's the most efficient way to burn wood, produces little to no smoke, easy to set up and lasts a long time without needing to feed the fire. Simply large logs at the bottom and then stacking in layers that are 90° to each other. Thin sticks on top and a normal kindle bundle that you light and that's it. Any moisture gets cooked out the wood underneath before burning and all gases get lit and used to create more heat instead of escaping out the chimney. It'll change your life lol. Cheers J
When using solar panels (or anything else which is variable output) you need a voltage booster/regulator on the output to lift voltage high enough for chargers to work (and stop them going overvoltage) A lot of "battery charging" panels have this built in but the larger ones usually have it as a separate item (a solar charge controller) WRT resins there are a bunch which are plant derived and recycleable but bear in mind that "recycling" is the nest step after "reusing" - if you can find something these scraps can be used in then it's worth incorporating them as filler
Thank you. The ecoflow has a built in charge controller which supports solar panels but for some reason isn't accepting the motors yet. I'll be trying a car alternator next. Cheers J
It might need more amps. So connect two turbines in parallel.
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 .
Awesome thank you. How ridiculous is that when lots of our power grid runs off biomass wood chips. Insanity... cheers J
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.
Thank you. Good tip. Cheers J
I think you sholud try the tesla turbine a shot is simple to build and i think is intresting
I'll definitely try it. I've got a CNC router to test out soon and I think the Tesla turbine is a good one for it. Cheers J
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.
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 :)
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
@@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
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.
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.
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
@@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.
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.
Thank you. That's awesome well done. Cheers J
Try, to power the ecoflow wall charger, instead of trying to charge it directly.
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.
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
I love to watch your videos. We are looking at them with my mate who lives on the boat and we will be developing some of your ideas. Keep making them. The size of the turbine really matters. I just had a conversation about it with my housemate. You are making a gear ratio however and that should solve this problem. (I am not a scientist. Even bigger amateur than you). Enclosure for the turbine. Now the air goes everywhere. 500V, 0.5A is 250W. However. You have mentioned that the motor in a turbine is 100W. I can assume that is was it the max output hence grinder didn't want to work. I recently had a similar issue with the laptop on the voltage converter. Only 80W, but the laptop wants 140W. The screen is blinking and the converter keeps going into an error.
Thank you. The grinder is AC and the output is DC so I think that's why it acts like a brake. I'll probably look at getting a different motor maybe an alternator that is energised by the battery. I'll get a better load test too maybe with LED strip lights. Cheers J
Check out MartyT ‘s channel, he’s of angry ram fame, has build hydro for off grid properties using a much raved about reworked washing machine direct drive motor. Only other thing that comes to mind is a doco I saw on tv which showed German hydro plant using split peltin cups to reduce water splash and drive up system efficiency. Great video, hadn’t even heard of resin printing, not sure I’d be a fan , but good to see. Looking forward to that filament vid!
Thank you so much. I'll check those out. Cheers J
Love the T-shirt! Where can we buy Joshua De Lisle merch?
Thank you. It was made by a fan. Cheers J
This is bloody brilliant this! When is the next film? Can not wait. This is the same project I am doing in Scandinavia, but in bigger scale. I have lots of wood. Heat up the house and get el. power at the same time. Perfect!
Thank you so much. I've got more lasers and other gadgets I've been roped into reviewing first but I'll be working on it on the side. I've got a CNC router to test also and I'll use it to mill some aluminium parts. Cheers J
@@joshuadelisle Really intresting. Thank you for anwser. Have a good night Sir.
Nice. 1968 at school built double cup version and 12v Mabuchi motor genr. Still low power though. How about a Stirling engine?
Thank you. Possibly but a sterling doesn't have as much power as steam. Definitely something to consider though. Cheers J
@@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. Robert Murray Smith KZhead channel has been playing with homemade generators and might be worth a look. Kind regards
@@trevorhorton8472 that's very interesting. An enclosure is definitely something to test next. Cheers J
I have often wondered why we don't use our wood stoves to produce the hot water and steam for electricity. Seams to me if you designed a stove that did you would have the most efficient stove getting the most out of the fuel you burn.
Definitely. Cheers J
Definitely. Cheers J
Would a stirling engine be a less expensive option rather than a steam engine lower heat needed for a start. Look forward to next video
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
@@joshuadelisle go spell checked that was supposed to be explosive not expensive 🙄 sill works though looking forward to you build 😁
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.
That's very interesting thank you. Cheers J
i'm not an engineer but i reckon that you'll capture most energy with an old fashioned piston
I believe I'll get more torque with a piston but also more friction. The generators need very high RPM to be successful which can be done with a high gear ratio but also ads friction. The official steam power used for the grid uses turbines so there must be something in it. Cheers J
@@joshuadelisle i'm really looking forward to this series, thanks for the vids
@@garygranato9164 thank you I'm going to continue until I get a working system that generates a reasonable amount of electricity. It'll probably be on going project to optimise efficiency. Cheers J
What about using Stirling engine(s) to generate power directly from waste heat in the chimney??
You can but they don't have much torque to generate anything significant. Peltier devices like a stove fan aren't very efficient either as most of the energy is needed for cooling the other side of the plate via a pump or fan. Cheers J
uhm didn´t saw your setup for charging the ecoflow, but the generator produces alternating voltage so you´ll need a rectifier to between the generator and the powerstation
The one I have is DC and has an inbuilt rectifier apparently but I think it's no good. I'll be getting a different motor for the next tests. Cheers J
Purely for the sake of measurement - maybe fit a large capacitor to overcome 'initial' load (much the same as washing machines use) - whether it is fitted in series or parallel may depend on whether you are using AC or DC (someone else can advise, or you can look that up though). Also for an ultra cheap way to compare lower levels of torque a cheap digital spoon scale could be modified to a simple torque gauge (they only cost a few quid) - for accurate absolute measurement calibrate against known torque, but it can reliably compare relative force to establish which produces more out the box. Without much modification I would just take the different cup designs and mount them to the spoon scale end and blast them with same air. search 'digital spoon scale' - from around £5
Excellent tips. Cheers J
Joshua - remember not so long ago when I recommend you check Steve Mould out? @16:00 you ask "...the physicists among you might give me some good advice..." - you two need to join forces ;)
I'll check him out now. Thank you for reminding me. Cheers J
@@joshuadelisle I took the liberty of emailing him and linked your video. Whether he checks his emails is another story. I don't do social media so ...best I could do haha. Take it easy bro
@@louithrottler that's very kind. Thank you. Who knows what may come of it. Cheers J
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.
I'm pretty sure it has MPPT. There is definitely a minimum I need to hit. Cheers J
The brothers Sentinel had a boiler system that would allow driving a steam car in 30 seconds, maybe you can find and use that boiler design. And how about a smaller nozzle but more nozzles so you use the same amount of air/steam.
Thank you. I'll check em out. Cheers J
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
add a 12v voltage regulator to output
I could but I think it would waste energy as heat. I think a different alternator is needed. Cheers J
I would've done that differently
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
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
I think you could put the whole buildplate into the washer bucket, no?
Yes you can. Cheers J
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
This one has a built in rectifier so its only a positive and negative coming out. I'm probably going to change it to a car alternator. Cheers J
@@joshuadelisle that's really atypical of these things and I could have sworn I saw three wires, but okay.
Tesla's bladeless turbine? The thin plates giving more surface area, would that work alright?
I'll give it a test. Cheers J
@@joshuadelisle woooooooo :D❣
*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.
Thank you. That gives me something to think about for the next design. Cheers J
😮
Light plastic turbines probably don't have enough mass to act as a flywheel to start the angle grinder. An aluminium turbine should be better. For corrosion, Aluminium Bronze?
I'll consider that. I can plasma cut stainless otherwise. Cheers J
Could you not use a high output car alternator?
I may do exactly that and energize it with the battery to create the magnetic field. It would seem they have a better output and cheaper too. Cheers J
Charge a battery, then use the battery to run devices. This way you arent putting a load on the generator itself.
do you have to but their resin? are they like other printer companies that make you buy only their ink?
Unfortunately yes but I'm trying to persuade them otherwise. I hate my Epsom printer for the same reason... cheers J
15:53 LET THE AIR OUT
Great point.
What do you mean?
@@joshuadelisle THE AIR MUAT BE ABLE FLOW OUT OR ELSE IT WILL STOP THE WHEEL.
@@ezruarn so a bigger outlet then. The turbine has an outlet that is fairly wide but could be bigger. Cheers J
Hey Joshua, are you using the Heygears Slicer: Blueprint Studio? I have a problem with that program, because all time i slice an projekt with it, it failed and i don't know why? Do you have an idea? Or do you have used an other slicer for it?
Hi. Are you using a Heygears machine? Are you adding auto supports before slicing?
@@joshuadelisle Hey, yea i use also the Quickstart guide for some tests, but all time the slice Failed. 3D Printer: UltraCraft Reflex from HeyGears
@@racnoc171 the technical support team is very helpful. If you can't get in touch with them I can ask my contact if needed.
@@joshuadelisle Hey Thanks for the help. I wrote them a mail, so lets see if they kann help me. Thanks for your Help man^^

Why was there a spark from nailing wood with nail gun at 16:35?🤷🏻♂️🤔
I'm not sure but it happens often. Could be steel dust from grinding getting hit by the nail. Cheers J
Are the resin containers for that HeyGears printer user refillable or do they have to be purchased from them every time they run out? If they are proprietary, and force you to only buy their resin, then it's an instant deal breaker. On another note, I really love anything turbine or fan design related. No idea why, but I always find it so interesting and fun!
@@joshuadelisle Oh nice! That's pretty great! Thanks for clarifying.
My first thought was also resin drm, glad this isn't it.
@@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
@@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.
@@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...
I wonder what shape the blades are inside a turbo? Also take a look at a Tesla turbine powered by air I’ve seen one of these spinning at about 140.000 rpm note every run killed the ceramic bearings. This vid can be found at johnnyQ90 it may take a bit of finding but it’s there
They look good and I'll definitely give a Tesla turbine a test but seeing there is a lack of working models used industrially Im suspicious of the ability to overcome resistance. Cheers J
@@joshuadelisle the one on q90 channel is one he made himself a miniature version the plates and spacers was made from aluminium cans cut into squares then put on a lave to make them round he did have to try a few times to get them balanced. The housing looked to be made from billet aluminium. I should imagine that if it weighed enough the torque at that rpm around a 140.000 should be plenty or certainly more than enough
@@trapdoorspider9211 nice. Cheers J
You should try a tesla turbine
you need diode for sure to prevent electricity from going back on that electric dc motor
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.
Excellent information. Thank you. Cheers J
Isnt the turbine blades too tight?
They're free moving on bearing. Cheers J
