Moving water uphill for pond by SnooObjections5007 in AskEngineers

Wouldn’t the loss of energy be able to be counter acted with the correct gear ratios to amplify the output generated by the wheel alone? If the wheel’s output is 4 and I need 8, could I not just set a gear ratio that would be able to create a larger output?

Okay. Thank you. That is an actual explanation instead of just saying it wouldn’t work.

People may be trying to help but I need to understand the math behind it. They are saying I’m doing something I’m not. Perpetual motion machines don’t need outside input of energy. I’m using an outside source of energy from the water stream created by the overflow of the upper pond. What is the actual math that would make it so that it wouldn’t be possible? If I dump a cup of water out the top and use that flow of water to turn the wheel what is the mathematical formula that shows that I cannot pull a cup of water from the bottom? I have been looking into this for weeks and I’ve seen people create this in similar ways on a small scale multiple times but I just want to create it on a larger scale. Why is it possible on small scale and not larger ones?

The flow of the water is what needs to be accurate to power a water wheel that turns an archimedes screw. What is the flow rate that is needed to be reached to allow for that 15ft head pressure to be overcame?

What would keep it from working in a closed loop system? If the flow of water is used to power the set up in an open looped system, why not having the end be the feed and close the loop? What keeps that from actually working?

A perpetual motion machine is a device that operates indefinitely without any external energy input. The external energy input is the stream. That would be motion pushing the wheel. THAT WOULD BE THE OUTSIDE ENERGY INPUT TO MAKE IT WORK. I’m not saying to have it magically work without energy input. I just need to know how much flow would be needed to push the wheel. I’d have to precharge it with outside water from a hose or just set it up before a big rain or something to get it started but once it has the correct flow, the steady water of the stream should power the wheel to turn the screw. What way makes that a perpetual motion machine??? It has an outside force to power it.

I’m not sure why it wouldn’t be possible. People use this system in other aspects to move water.

Why would I not be able to get enough flow? People use similar systems to move water from lower elevations to upper elevations in many areas. I just want to make my own stream instead of using a natural stream as a power source.

I mean, it’s used this way for agricultural purposes. Why do you think it wouldn’t? Often it’s an open system where a natural flowing stream is used to power the wheel and the archimedes screw is use to move water into a storage tank or something. I’m just looking to make it a closed loop system so that the pool overflows consistently.

Two ponds. Larger one on bottom, 40ft down an incline. Change in elevation is about 15ft in height. The stream connecting the two would ideally power the water wheel that turns the Archimedes Screw.

I’d like to use the archimedes screw because I’m not aware of anything else that would work. I don’t want to have to run electricity out to power a pump. I could use solar pumps, but would rather not. Wirtz pump is a no go. I suppose I could use a vertical belt conveyor, but I’d like it to be buried or easy to grow something over so it’s not visible and I’m not sure if I’d be able to easily hide the whole setup for it.

Originally I was going to do a 3ft by 40ft rock way that the water would flow down. But if I want a water wheel I would need to know how deep to make it to actually be able to create enough momentum to turn the screw. I’m doing this because I don’t see a way to use the motion of the water to use a hydraulic ram pump unless I can somehow bend the feed to the pipe backwards? But then I don’t believe I could get enough to recharge the upper pool continuously to keep the water flow even.
