I really appreciate the comment but I want to point out I'm not working off the motor regen (don't believe it has it). I'm actually working against its normal rotation allowing for maximum output with no controller currently. I will double check to ensure this is the case. Thank you!

@@Beyond_The_Print Anyway - the point stays the same and I will reformulate it : This hub motor, when working in mode of synchronous three phase generator is designed to reach its pick electrical power output at arround 500 rpm or 8.5 rotations per second. Adjust the turbine design and height of water fall, or use gear ratio that will bring the generator at 500 rpm and you will gain maximum power. No matter that you do not use controller. The same 500 rpm states for raw power from your generator. The point of my comment is to help you : which rpm value to aim in the design.

Thank you for the support and subscribing!

This could be a bit misleading, if the speed of the motor increases due to the change in ratio the power would be expected to increase. I believe your example refers to when the maximum amount of energy is captured by the turbine then changing the ratio would have limited effect.

@Beyond_The_Tint No I still stand by my original statement. If you think about an electric bike, the power output of the motor is the same regardless of what gear you've selected. If you take your wheel and replace it with a turbine then no matter which gear you select, the power generated by the motor is the same, only the speed changes if you change the gear. Source: I'm a mechanical engineer.

If power Is the ratio of torque to speed then this must not be true. If torque is the same and RPM increase then the power must also increase. Also a mechanical engineer

@@Beyond_The_Print but the torque is not the same. When you change gears to increase the speed on the motor, the applied torque to the motor decreases. The power put into the system by the waterfall is just transferred to the motor through the gears and is conserved. If you could get increased power using a chain and sprocket, then you could just keep increasing the ratio for an unlimited amount of power out of one waterfall.

@@RyanHenrie999 check out my Pelton turbine videos. The pulley and belt increased the power of the motor because it allows for the fine tuning of the optimal power output. Obviously this cannot be done unlimitedly but there is potentially a "sweet spot" for more power.

You should check out my Pelton turbines! I've been working on a few different ideas to try and make this work. Stay tuned, thanks for the suggestions and I'll have to try flipping it over

It was an extra from an ebike I go. They can be found all over ebay and Amazon!

@@Beyond_The_Print Thank you. Excellent video.

@johnemmanuelle6821 no problem! Glad you liked it

I actually tried letting the emergency hooks hold the weight it seemed to do alright!

Hopes and dreams currently

I think so too!

Are you referring to the blog post? If so that's not owned or operated by me In any manner. I really appreciate their post and time it took to write it! Thank you for the kind words on my channel and I've been trying to think of an design to generate power from this as well. I was also considering a wave generator but this is vastly more complex

This is a good idea too! If you haven't seen the open style one check that out. We were able to get a little more power out of that one

@Beyond_The_Tint I watched that first. Still your closed buckets allows you to slowly cut away now and figure out the optimal water flow.

Haha the cold wasn't helping my case

@@GrumpyDohBoy thank you!

I should have tested this with how easy it would have been

I just looked into the crossflow wheel turbines and I love it! Thank you and I see what you're saying in this test. Thank you for this input

This is great advice thank you!

idk but I received a free hoverboard and I'll be gutting it and shrinking whatever stl you make work the best lol

@PhonePhone-sf8te haha good one

@@Beyond_The_Print you probably need to go towards a high head low flow pelton design, that is if you have actual elevation where you live to work with. Or start working with those gears but they won't really do anything unless you put the water wheel on something else and then run the chain to it. 30 watts isn't that bad though when it's running 24/7

@@PhonePhone-sf8te thank you for this! I have played around with a Pelton turbine before if you havent seen those vids. I am limited to my elevation for the time being but hope I can improve this in the future. I'm currently working on some ideas for just this (separating them via chain drive) stay tuned!

@@Beyond_The_Print Oh cool, no I didn't see them, but I see you've been at it for a while. Keep up the good work, I'm definitely going to be watching them all.

That's a great idea! I hadn't considered this at all and I agree seems like the original may have been the optimal design in this location.

Thanks for the correction and write up! That is correct they often directly function of the weight of the water in the bucket rather than the impulse of water hitting the blades. I've tested a Pelton style before and would like to try it here but the issue would be water hitting the returned water ruining efficiency. I'm looking into better designs currently, thank you again.

@@Beyond_The_Print As you got what essentially boils down to a sheet of water instead of just a thin stream: use half a pelton. Normally it is redirecting the water 180° to get as much momentum out of it. In your case you have way way more water and energy available so just a 90° diversion should be plenty of power and make the water clear the path faster.

@@ABaumstumpf I like it, time to get designing

That's an awesome idea! Im going to look into this further!

Agreed

That was my idea low speed high power! Thank you

That one looks a little bit different from what I can find

🤣🤣 I'm gonna have to

This one is yes

Thanks for the comment, I'm glad you like it!

Starting the next print right now!

Thank you, can't wait to see where we take it!

This is correct! Next we work on increasing RPM

Thank you!

It's the ends that the pipe bolts into that is metal (whole short is posted with it and my full video shows this more). It really is EMT tubing with braces I printed haha

Thank you! From all of my other projects I would have to agree simple = better especially for design changes

I just want to thank you for the time and effort for writing this comment out! I wanna correct your gravity value for accuracy (9.8m/s^2) but that's a great point I should have included. I don't think the scatter effect is within reach currently but is also I future concern. I agree there is definitely an ideal paddle size and it can be improved. I probably should have lead with this but your comment on making it a scoop is genius! I thought of doing that but wanted to keep the cost low on the first test as this would require support to the top of the print. But for power I will do it! Thank you

@@Beyond_The_Print I knew that gravity effect was wrong, but I was honestly too high to double check. If it's not possible to make a scoop, the other idea I had was raised circular patterns on the paddle. Or boxed. The point being to capture the energy so it has resistance, so it doesn't disperse so easily. I'm happy I could help with some ideas. I wish you the best of luck.

@geminiveteranllc haha, I can most likely do the scoop design just hopefully can use tree infill or there will be alot of waste. I'm going to work on it tonight I also got a new printer I want to try so I may lose a little but I think it will be minimal as I'll shrink inner circle as well. Stay tuned!

Oh good idea 💡

@@Beyond_The_Print worse case stretched over lapping black electrical tape will do the same thing

I'll get right on it. Thanks again

Thank you

Looks like I habe something else to test, that or a sail boat was mentioned too!

Thank you! You gotta start somewhere

@Beyond_The_Tint don't stop. I subscribed to your channel.

It's the sprocket that's supposed to drive the ebike the motor came out of, but he's repurposed it in this video, hope this helps 👍

I couldn't have said it much better than this! Currently it's driving nothing (that will hopefully change in the future). I just figured id leave it on for now as hopefully I'll design something to utilize them in the coming future.

Now I understand. I didn't watch previous videos so wasn't sure. Can't wait to see what you do next.

Thank you I appreciate it! We've come a long way and have so many amazing people here

👊

I agree and wish I could, unfortunately I don't own this land but I might have something in the works! I will look into these turbines further as well.

Thank you for this advice, I agree it will start to rust. It's one saving grace right now is the sheer amount of grease on it from being in use. Good idea I'll work on this

@@sneakybutpirate that's sounds perfect. A plexiglass window would be nice.

I needed this!

@Beyond_The_Tint great! I hope to see a follow up whete you make the frame work to hold the wheel in the water. Although that may be better off as a wood working project... not sure how well a plastic support structure made by a printer would do under the water pressure Btw if you are interested in generating power from water, i strongly recommend looking into VORTEX water generators. The wheel is horizontal, inside a circular frame. And you create inlets for water to push through. People have installed ones with 2 and even 3 inlets. They rework the stream/river so the water splits into narrower channels, one per inlet. And then using pipes/hoses they attach the inlets to the circular wall at the holes created for the water to exit and spray out. You can add valves before the outputs, incase TOO MUCH water is going / going too quickly, which may damage the gennie. Its very very effecient and should net much more electricity! Goodluck in your exploring of thjs

Thank you! We've come a long way!

Thank you so much! Looking forward to what's next

Thank you, I've been working on some designs for just this!
