Viewer engagement! Utilizing the waste water from the seesaw into a collection tub could subsequently be dispersed passively into a garden or flower bed!
You can certainly do that but oftentimes you want the pump at the very bottom of your site to gain maximum pressure, or so far away that the wastewater is useless anyways.
Very interesting concept, maybe you could use more see-saw's to make the flow a bit more continuos and maybe you could more airbags for more power I also though about " stacked see-saw's " where water after exiting one see-saw would come to a system that would stabilize the flow to another see-saw and so on, making the machine more continuos and water-efficient.
Hi Joe. The air bag use made me think of semi’s air brakes. Same principle: ~ low pressure air on a big diaphragm creates great force on the brake drum pistons. Unlike the air bag, the air brake diaphragm is designed to maximize the incoming pressure. You could try with a salvage yard air brake. Make sure you get a “service” air brake n not one with the parking brake attached. Also they can be opened and repair parts are readily available.They have a return spring that could be sized to just return the diaphragm or turn it vertical like the Aussie pump and let gravity return the diaphragm. Just a thought. Good job. Keep at it.
If anybody tries this, be aware that there is a very large extremely strong compressed spring inside of these brake Chambers. If you don't take them apart properly they will explode in your face.
All together this is a very ingenious system, I love the whole mechanical system. Watching the dead time at the end of a pumping stroke when the seesaw is filling up, I'm trying to think of ways you could "tune" the cycle time to make it cycle faster. The water at the ends of those 3" pipes is what makes it tip over, the water in the elbows where it fills up near the pivot doesn't contribute much, so maybe your kid was onto something: pack out the pipe elbows with something lightweight (a tennis ball?) so the water goes straight to the further end of the seesaw reservoir and makes it flips faster. Just spitballing.
Good ideas! the only problem is to make it go faster I would need more water. Padding out the seesaw might be something to try, but I rely on the water near the elbows to give it a boost in torque as it tips over.
A google search for gravity pump came up with a pump called the Highlifter from some company that's very similar to this. Instead of a ram pump it uses the varying surfaces areas to balance out it's forces. I'm not saying you should buy one (where's the fun in that), but it might be interesting to look at to see if you can use some ideas from it to modify your design.
I like that it will run on any head pressure, any flow rate, that is a BIG versatility advantage over a ram pump. You should pat yourself on the back for that. Next you should check if it is more water efficient to have the valve and bellows middle step, or better to drive the high pressure cylinder directly from the teeter-totter. Which would obviously be a cheaper and simpler design. And I would assume most people would use a creek to power one of these, so water efficiency wouldn’t be an issue, they would just be looking for max pressure and output flow regardless of waste. It might require a bigger teeter totter though. I really enjoy your videos. Thanks Joe!
Very interesting, I have been considering a ramp pump for one on my creeks to fill water tanks to water gardens, this system looks very promising and thought out. Love following your turbine build- both of these will be included in a new homestead build
Loving your progress on this whole series. Tapping into nature for clean power and even recycling the water for more and more uses of a renewable resource.
U did a great job !! Thanks for all the videos and sharing the information!! I have nothing negative to say my opinion is them kind of people need to keep it to there self !!!
very interesting concept, I would like to see some actual data regarding the water efficiency compared to a ram pump or other similar fully-contained systems
Use the toilet flush system, as the piston comes up it pumps the water, under neath an attachment pushes up the toilet valve when its fully up and releases the water, the piston falls down and restarts again.
Hi Joe; The SeeSaw system doesnt perform very efficiently. It’s function is essentially that of force multiplying lever. The further the weight of the water is from the fulcrum in the center the greater the force on the valve. The problem you have is the use of large diameter pipe in the central section of the SeeSaw. Water in the central portion has less ability to produce force than the portion near the ends. My suggestion is to only have the water cups at the ends where more force is developed using less water. redrok
it does seem there is a lot of water used in the valve switching function. Perhaps if Joe put 500ml in a sealed 2 ltr soda bottle and taped that to the lever he originaly the load would shift giving more switching force without significant water loss
A very interesting idea and proof of concept! I am looking forward to more of this video series as well as all the others you have going at the moment!
you could stair case these, have the supply break off into multiple distribution, then put some more "devices" below so you could have 3 pressure systems
If you put lips on the exit ports if your seesaw pipe, just after your drain holes, the moving water would hit it and impart some of its energy to the movement of the seesaw (more torque). The water blocked would then drain though your drilled drain holes. It might mean you need a little less water in the seesaw per cycle.
An idea for your see saw. Instead of water chambers on both ends you could just have a weight on one side. It might make it cycle faster. Back in earler times people would use a bucket ander a flow of water to raise a weight. Once the bucket got full, it would tip over and the weight would fall. They used them to mill corn. Also it would interesting to see a direct compairson with a ram pump.
Very interesting application of physics. Apparently the natural curiosity to experiment runs in the family! Never too young to start, the young just need more supervision and direction!
I would say that this works like a gear reduction. For example you could make a whaterwheel and gear it upp to drive a waterpump. Meaning the water wheel don't need a high pressure but needs spin more turns than the pump which would make the pump slow but very strong.
this is great, low flow and self starting and will pump if air gets in the lines . maybe having a 2 way hose splitter with a kind of "debris" catch can, and the debris could go into the trickle part as that will not block the valves
love the video, the pump looks great, hope that stache grows itself in nicely, right now its more of soup strainer than soup catcher.. (yes, we are all obsessed with your stache)
@@JoeMalovich The (discontinued) Remington Titanium MB 70 Beard Trimmer is a nice one. It has a fan in the bottom to draw trimmings into a catch 'bucket'. I did a bit of work on mine to make it better. First thing soon after I bought it new years ago was to take it apart and use a small drill bit to open up all the holes in the exhaust grilles, many of which were nearly blocked by flash. I also removed flash from the fan blade and positioned it on the motor shaft so it'd be as close as possible to the inlet opening in the shaver housing. Suction improvement! Some time later the small pair of NiCd cells died. I found a video on RUclips showing how to swap them for a pair of NiMH cells. For small things like this a NiMH will directly replace a NiCd. Takes longer to charge but holds more charge, and won't self discharge anywhere near as quickly. Can charge it up to go on a trip and leave the charger behind. My previous trimmer had the same dead NiCd problem. It used a single AA cell, which I replaced with a NiMH AA cell from a defekt cellphone battery. It was an early "small" phone which was between the Brick and the MicroTAC. The other three cells in the battery were bad. I got the Remington when the other one died completely. I've been using the MB 70 for much longer with the NiMH than the original NiCd lasted.
Very interesting, I've seen one of these used in agricultural applications.. but never a home made one.. I like the concept! Whats the efficiency vs a Ram Pump?
this is a great new idea nice experiment. have you ever heard of a siphon pump? they have alot more pressure and flow than a ram pump and waste very tiny amounts of water. they are a little bit harder to understand though so ya don't see them often
Very interesting design and good job explaining it. I wonder though why you wouldn't want to look into a Venturi /airlift pump since you have running water and a pen stock. As you might know venturis can be used for a lot of applications. one of which is to draw in air and mix it with the water. If the water air mixture is then is put out inside an airlift pen stock you are effectively using Air to lift the water inside the outlet pipe of the airlift pump. A venturi can draw its air/liquid(it is a vacuum pump) from where ever.
GENIUS! Instructive and helpful. Thank you very much Joe! I thought last time that it was about a kind of irrigation system we find in Asia... THIS IS REALLY INSPIRING! GREAT JOB! Can't wait the larger project.
Awesome! I figure the rocker should have some kind of latch that disengages when the piston reaches the extremes? It feels like you loose some efficiency by allowing the piston to sit there fully extended or retracted. But uh... This is awesome! I love seeing genuine inventions! So incredibly excited to see more of what you do with this. Well done!
Great idea, I was thinking why not use the stroke of the airbag to actuate the valve, just use a lever to Invert direction of travel, one at max stroke to flip the valve, one at min stroke that pushes the valve open again.. if that makes sense
hmm very interesting! what are the potential uses once fully developed? perhaps you need a cascade seesaw? drain the first two into the next two etc so the first drives the second which automates the pump maybe?
heres a thought, if you have falling water from your hydro water power system which i would assume you would, why not set this up near it, get a long 6' to 10' pipe to catch that water falling from that system to feed this system. only need to have a couple degree angle down and gravity will do the work, rather than burn out your spring/well. and that i am assuming is using a pump to feed the hose so you also are using electricity for this. when you can use FREE gravity feed from a system you already have. Unless it is a hydro unit submerged in water. But even so you can damn up a part of your waterway and raise its elevation and create a small waterfall to feed this. I do like this pump design if it can be scaled up and get better waterflow. IF so I will be building one for sure, please let us know of your progress by updating videos. Good work.
ok i have a question im sure it would work . how about hooking the water wheel up to the air bag so that when the wheel turns it pumps the air bag back and forth ? instead the water driving the pump the wheel would basically lol suck and blow . another thing is you loose alot of water out of your feed pipe with the way its set up now why not fit a 50 gallon plastic barrel right to the feed pipe . you would only have water loss then if the barrel over flowed .
Take this concept and combine it using the waste water from a ram pump as your source to pump the waste water back to the source for the ram pump could this then truly be ”free energy" ? Awesome build man
Could you hook up a second set of air bags and valves on the opposite side of the seesaw pivot/fulcrum switch...thing, to pump twice as much water? And with the second set attached to the same fulcrum switch, there should be twice as much "exhaust" water to fill the 3" PVC pipe collection fulcrum activators, which should fill those 3" PVC collectors twice as fast...I think, not too sure. I just did a little "shoot from the hip" math and my results could be WAY off.
This is great! I was thinking about practical use in an off grid situation. What might you encase the system in to ensure unobstructed use over a long duration? How far up hill will the unit pump?
Sorry if I come over all helpful, but 1. Eliminate the two round holes and fill directly a single piece of teeter totter pipe that doesn't spill and is much longer than the present setup 2. Arrange for the stroke to be directly, vertically, applied to the pumping cylinder I liked your review of preexisting components that are available
6psi out of downhill, in a 10 mm pipe? How? What's the full apparatus? How, are you generating pressure & thrust? I mean, even in your turbine, how do you generate that much pressure? Did you dig a pit and are storing water like a reservoir or a dam? And also what's the length of your pipe and what height is your water falling?
I think you can make it more water efficient if you put only one pipe that fills attach to a spring. The weight of the water wins against the spring force but when its empties the spring retract the seesaw, ,with the pipe to its initial position or something like a sōzu mechanics.
First I want to thank you for sharing your work with everyone. Second, I have a question related to your attempt at actuating the system around the 9 minute mark in the video: I'm curious what the result would be if at the top of the aluminum bar was a horizontally mounted cylinder (of which the diameter and length I have zero advice on...lol, again, this is a curiosity!!!) that is capped at each end and filled part way with some media or possibly water? The thought came while watching the device actuate one direction, but not the other. I wonder if the proposed cylinder was partially filled with sand, how the shifting weight would possibly help with the force needed to overcome the pressure as well as aiding in the timing of it's swing? Thanks again for sharing your ideas and invention!!! Good luck to you and I hope this helps in some way!
Wonderful!!! ❤ THIS is how all of us could think. I did not see PEX bands on every connection -- did I miss them, or is it not necessary (the low pressure maybe)?
I have been researching the Ram Pump to operate a Micro hydroelectric system and ran across your see / saw, bladder & value set up. Have you given it a name? This was a mouthful. I'm intrigued and wondered if you did any more testing on it during winter spring water flow? What was your optimal lift pressure attainable?
Great description of your pump. I'm going to intall a pump in the stream on our border, and so, is this system more efficient than a ram pump or not? A ram pump seems a lot easier to make, and maybe cheaper, but efficiency is the most important, as far as I'm concerned. Have you done any comparisons? Second, for a ram pump the arrival "must be strait" is always emphasized. My stream is not a line direct from the highest point to the ideal pump site, it's a wavy stream. Does your pump need a strait line for its arrival pipe? I really appreciated this video, and I'd really appreciate it if you could answer my questions... please?
This looks like a more complicated version of a bunyip pump which uses a tire for the main diaphragm and a piston to create the pressure. I don't think that there's an actual valve, just creating and breaking the seal from the side of the tire.
The set up is good BUT if you had more water coming in, you would have a GREAT SYSTEM. In my opinion is too many parts and maintenance will be an issue
Here's an idea you may be able to incorporate into your design, add some sort of Kids Pool to trap the water being used in the pump, then recycle it to be used to fill the motion section. That way in seasonal dry times you can just fill the pool with rain water and still pump it somewhere or whatever the need may be. You can copy your pump design, and pump the Pool water from the pool to the pump, thereby making the entire thing work off grid and possible with more pumps increase water pressure... Just a thought that you design inspired; I hope you are able to use it... Cheers...
i would add a pivot lever to equalize the strokes so that each move makes a full stroke looked like your setup was short stroking the large bag most of the time. also i believe if you had 3 timed in 60 degree phases from each other you could get almost continuous flow though at a proportionally lower rate than your input.
Interesting concept . My thoughts are : Math >> I dunno about using a square dimension for a cubic volume @ 7:38 > I thinking that you are essentially blowing up a balloon from an air compressor,, disconnecting the air compressor ,, taking the balloon anywhere in the world you want .. and using what is stored to do work. Last bit of advice regarding science... Don't spend much money on scale until you can absolutely and 100% predict ANY scale. Just do a minimal re-hash, kinda like a baby step. Maybe 2x up OR 2x down AND most importantly PREDICT the outcomes you desire/wish .... When you got the formula correct by proven experiment .. then .. well .. anything in the future is just planning for scale
Hey I like your thinking on the mechanics. Question. What about using bicycle inter tubes as a cheaper and easier alternative? Also, I think your answer to some of the mechanics lay in the Watch and Clock mechanisms. Have you looked into this? You can buy the book of 501 mechanical movement. This might help you. Also, you can buy a single stage air left shock. Check out the one's used on the old GMC RV Coaches of the 70's. They used this type to left the RV up and down and for Leveling the Coach. Maybe you should use two weighted Floats instead of the PVC pipe to move the Water. Check out the (Pythagorean Siphon). It may work for you. You can find this system inside the newer Washing Machines. Thanks for the upload.
Won't be faster if have another set on the counter part of the see-saw? Also collecting the wasted water and make a watermill to pump back to the see-saw ? it may save water and increase pressure by reducing the first drop, of course I have no idea how much efficient will be
Maybe go back to original design but add in a guide rail that would allow a ball bearing to roll back and forth. What I'm seeing in my mind would cause less waste water thus be able to pump more?
Put rocks in the tube just under the weight it takes to actuate. Less water to fill tube, and faster the action, I think. Your little one might have been on to something. Inspiration could come from anywhere.good work.
I've always thought about the loss of water in these types of pumps and it bothers me. I wonder if there is a way to reclaim the system losses. I'm sure something like this would be useful if you can't get electricity to the pump location, but seems like solar energy and battery storage would be more efficient.
I always think about this same thing with gravity based pumps. But thermodynamics always gets in the way. You can keep going down the rabbit hole but is it worth it? Great design Joe. Wonder if there is any gain on going with a longer stroke out put "pump" and adding a check valve?
This would be a way (possibly) to pump water up from my creek that is 140' below my house, and in deep woods. The "waste" is just water that will continue on it's way to the river. The pumped water would be able to feed my garden without having to use the tap. Fantastic.
So just a question why wouldnt you produce electricity with this pressure and use a small electric pump to produce the pressure you need. You can the bank the water upstream generate electricity, use the run off water down stream using a pump to wheverever. Since you have electricity you can use it downstream. Also when you are not pumping water you can use the electricity to do somethign else. Electric Pumps are very reliable easy to replace , electricity is easily transportable. Also It is easy to produce electricity with water or Solar. These pumps just do pumping but nothing else. And they arent cheap either or fast. Also may be use the water pressure to directly run a centrifugal pump instead of this setup.
Interesting. A ram pump gives you more Consistant flow and may be a little more, I won't say efficient as and waist can be returned to the stream or river you are using as a source, but maybe less wasteful of the supply. Not to mention the ram pumps are going to be a lot more cost effective. Still a very interesting concept.
I wonder if you could have 2 pistons on the same seesaw, have one open while the other is closed? I guess you'd need 2 of those valves, I'm also not sure if that would actually help at all.
Very interesting concept, and it’s great that you got it working. Really cool! Unfortunately, I think it is extremely complex when compared to a ram pump. Meanwhile, ram pumps are elegant in their simplicity, with only two moving parts. I think that ram pumps can yet be improved upon, and offer many opportunities for further innovation.
@@JoeMalovich and it’s brilliant that you did! It’s fantastic. I think you should go improve upon a time tested design now though. Bring ram pumps into the future for us. If anyone can do it, you can, and I know there is much room for improvement in the ram pump designs of today, which have seen only marginal improvements since their invention.
I think your design could benefit from a pilot operated valve which would alllow for a much smaller cycler and because of that much less water wasted. Or it might even be easy enough to actuate with your first attempt with the over center lever
Pilot valves like a bunch of pressure to actuate, I fear that my 0.5 PSI or even 6 PSI water source isn't enough, and I don't want to use my high pressure water for pilot actuation because how would I start the pump?
I saw something like this in the mother earth news. They put a styrofoam float in a 55 gallon drum, when it floated to the top, it opened a valve that drained the drum and the cycle repeated. It was very slow, but constant.
Hi Joe, thanks for the good work. I was imagining here having seen the clip, how about if instead of the seesaw mechanism, one used a cam mechanism where say a roller displaced by the sac movement moves round a cam to aid in pressurising the pump. You could try it if it's ok.
Hey Joe, love the videos. Keep them coming. Have a look at the “bunyip” pump. The valve issue is solved and can pump to a huge 200m head (600+ft) on a tiny fall of only 600mm (2ft)
Yes I've heard of them, but they cost like $2000 and ship from NZ. I guess this is like a Bunyip pump in a different configuration. I'll address this in the next video.
So a question, if you use the water drainage off this pump to go into a container and feed that water into another pump that pumps to the feed bucket of the first pump. Would you then have 100% use of the water?
Such an idea requires more pressure then this system is expecting. However if those such pressures where to exist at the head, i dont see why you couldn't run another pump style to move the wastewater back to source. Perhaps even tied into the seesaw as a driving mechanism.
Sorry, but this video told me nothing. A ram pump can lift water say 40 m. How high can this pump lift any water, and from where does the pumping energy come from?
putting "free energy" in the thumbnail might attract the wrong crowd, good video tho
I can silence the stinkers.

A venturi can draw its air/liquid(it is a vacuum pump) from where ever.
Those require a bunch of water, this will run on a trickle
GENIUS! Instructive and helpful. Thank you very much Joe! I thought last time that it was about a kind of irrigation system we find in Asia... THIS IS REALLY INSPIRING! GREAT JOB! Can't wait the larger project.
Thanks!
Reminds me of the Bunyip Pump
Awesome! I figure the rocker should have some kind of latch that disengages when the piston reaches the extremes? It feels like you loose some efficiency by allowing the piston to sit there fully extended or retracted.
But uh... This is awesome! I love seeing genuine inventions! So incredibly excited to see more of what you do with this. Well done!
That's a good idea about the catch, it would certainly prevent short-cycling. My problem now is I'm having long-cycling because of low water flow.
This is a very interesting concept.Why not incorporate two bags so as they will alternate between intake and exhaust? That would double the output.
Great idea, I was thinking why not use the stroke of the airbag to actuate the valve, just use a lever to Invert direction of travel, one at max stroke to flip the valve, one at min stroke that pushes the valve open again.. if that makes sense
That is amazing. Thank you for your video. I am buying a house with a spring on it and want to pump the water up 38 ft to house.
Nice thought process here. A heads to competition with land to house would be fun.
Good job Joe Malovich
hmm very interesting! what are the potential uses once fully developed?
perhaps you need a cascade seesaw? drain the first two into the next two etc so the first drives the second which automates the pump maybe?
Potential uses are limitless right now.
interesting idea.! but the higher the outlet pressure, the more water is needed at the inlet ...
You should used electronic timer relay, battery and small solar panel.
If you were to put a V between the 2 pipes like a slide back to back it would help it from getting stuck in the middle
heres a thought, if you have falling water from your hydro water power system which i would assume you would, why not set this up near it, get a long 6' to 10' pipe to catch that water falling from that system to feed this system. only need to have a couple degree angle down and gravity will do the work, rather than burn out your spring/well. and that i am assuming is using a pump to feed the hose so you also are using electricity for this. when you can use FREE gravity feed from a system you already have. Unless it is a hydro unit submerged in water. But even so you can damn up a part of your waterway and raise its elevation and create a small waterfall to feed this. I do like this pump design if it can be scaled up and get better waterflow. IF so I will be building one for sure, please let us know of your progress by updating videos. Good work.
ok i have a question im sure it would work . how about hooking the water wheel up to the air bag so that when the wheel turns it pumps the air bag back and forth ? instead the water driving the pump the wheel would basically lol suck and blow . another thing is you loose alot of water out of your feed pipe with the way its set up now why not fit a 50 gallon plastic barrel right to the feed pipe . you would only have water loss then if the barrel over flowed .
Great work joe. I dig the videos. Always fun to build things that work.
Take this concept and combine it using the waste water from a ram pump as your source to pump the waste water back to the source for the ram pump could this then truly be ”free energy" ? Awesome build man
I would love to have one of these to try out at my house.
Could you hook up a second set of air bags and valves on the opposite side of the seesaw pivot/fulcrum switch...thing, to pump twice as much water? And with the second set attached to the same fulcrum switch, there should be twice as much "exhaust" water to fill the 3" PVC pipe collection fulcrum activators, which should fill those 3" PVC collectors twice as fast...I think, not too sure. I just did a little "shoot from the hip" math and my results could be WAY off.
the see saw. beautiful.
This is great! I was thinking about practical use in an off grid situation. What might you encase the system in to ensure unobstructed use over a long duration? How far up hill will the unit pump?
Sorry if I come over all helpful, but
1. Eliminate the two round holes and fill directly a single piece of teeter totter pipe that doesn't spill and is much longer than the present setup
2. Arrange for the stroke to be directly, vertically, applied to the pumping cylinder
I liked your review of preexisting components that are available
6psi out of downhill, in a 10 mm pipe? How?
What's the full apparatus? How, are you generating pressure & thrust? I mean, even in your turbine, how do you generate that much pressure? Did you dig a pit and are storing water like a reservoir or a dam? And also what's the length of your pipe and what height is your water falling?
pressure comes from gravity pushing the water downhill, like a watertower.
@@JoeMalovich Exactly my point, how high is the water level in your hydropower setup?
Can't wait to see where this goes. Cool idea
Me too! I'm still building things in my mind though so I don't tknow where I'm going.
I think you can make it more water efficient if you put only one pipe that fills attach to a spring. The weight of the water wins against the spring force but when its empties the spring retract the seesaw, ,with the pipe to its initial position or something like a sōzu mechanics.
First I want to thank you for sharing your work with everyone. Second, I have a question related to your attempt at actuating the system around the 9 minute mark in the video: I'm curious what the result would be if at the top of the aluminum bar was a horizontally mounted cylinder (of which the diameter and length I have zero advice on...lol, again, this is a curiosity!!!) that is capped at each end and filled part way with some media or possibly water? The thought came while watching the device actuate one direction, but not the other. I wonder if the proposed cylinder was partially filled with sand, how the shifting weight would possibly help with the force needed to overcome the pressure as well as aiding in the timing of it's swing? Thanks again for sharing your ideas and invention!!! Good luck to you and I hope this helps in some way!
I always had this idea, but never made it. Great job!
Awesome content. Wish I had water on my property. Would love to be experimenting like this.
Wonderful!!! ❤ THIS is how all of us could think. I did not see PEX bands on every connection -- did I miss them, or is it not necessary (the low pressure maybe)?
It was the low pressure and I was constantly adjusting things.
I have been researching the Ram Pump to operate a Micro hydroelectric system and ran across your see / saw, bladder & value set up. Have you given it a name? This was a mouthful. I'm intrigued and wondered if you did any more testing on it during winter spring water flow? What was your optimal lift pressure attainable?
Nice job Joe.
Great description of your pump. I'm going to intall a pump in the stream on our border, and so, is this system more efficient than a ram pump or not? A ram pump seems a lot easier to make, and maybe cheaper, but efficiency is the most important, as far as I'm concerned. Have you done any comparisons? Second, for a ram pump the arrival "must be strait" is always emphasized. My stream is not a line direct from the highest point to the ideal pump site, it's a wavy stream. Does your pump need a strait line for its arrival pipe? I really appreciated this video, and I'd really appreciate it if you could answer my questions... please?
You should jump a flywheel on the generator for more inertia.
Also by the tree put a drop tank so we can pressurize more water
This looks like a more complicated version of a bunyip pump which uses a tire for the main diaphragm and a piston to create the pressure. I don't think that there's an actual valve, just creating and breaking the seal from the side of the tire.
Same principles, different implementation.
The set up is good BUT if you had more water coming in, you would have a GREAT SYSTEM. In my opinion is too many parts and maintenance will be an issue
Hey man, trim that flavor-saver on your lip!!! LOL
Why? Because I told you to !
Here's an idea you may be able to incorporate into your design, add some sort of Kids Pool to trap the water being used in the pump, then recycle it to be used to fill the motion section. That way in seasonal dry times you can just fill the pool with rain water and still pump it somewhere or whatever the need may be. You can copy your pump design, and pump the Pool water from the pool to the pump, thereby making the entire thing work off grid and possible with more pumps increase water pressure... Just a thought that you design inspired; I hope you are able to use it... Cheers...
i would add a pivot lever to equalize the strokes so that each move makes a full stroke looked like your setup was short stroking the large bag most of the time. also i believe if you had 3 timed in 60 degree phases from each other you could get almost continuous flow though at a proportionally lower rate than your input.
Interesting concept . My thoughts are : Math >> I dunno about using a square dimension for a cubic volume @ 7:38 > I thinking that you are essentially blowing up a balloon from an air compressor,, disconnecting the air compressor ,, taking the balloon anywhere in the world you want .. and using what is stored to do work. Last bit of advice regarding science... Don't spend much money on scale until you can absolutely and 100% predict ANY scale. Just do a minimal re-hash, kinda like a baby step. Maybe 2x up OR 2x down AND most importantly PREDICT the outcomes you desire/wish .... When you got the formula correct by proven experiment .. then .. well .. anything in the future is just planning for scale
Hey I like your thinking on the mechanics. Question. What about using bicycle inter tubes as a cheaper and easier alternative? Also, I think your answer to some of the mechanics lay in the Watch and Clock mechanisms. Have you looked into this? You can buy the book of 501 mechanical movement. This might help you. Also, you can buy a single stage air left shock. Check out the one's used on the old GMC RV Coaches of the 70's. They used this type to left the RV up and down and for Leveling the Coach. Maybe you should use two weighted Floats instead of the PVC pipe to move the Water. Check out the (Pythagorean Siphon). It may work for you. You can find this system inside the newer Washing Machines. Thanks for the upload.
Won't be faster if have another set on the counter part of the see-saw?
Also collecting the wasted water and make a watermill to pump back to the see-saw ? it may save water and increase pressure by reducing the first drop, of course I have no idea how much efficient will be
Have you seen the bunyip pump? It uses a tire I think instead of an airbag.
Yes, but I didn't want to copy it.
Very good.
I hope to see a new and improved commercial grade one asap
Don't hold your breath on a commercial version.
I dunno if it is better than a ram pump.. ram pump has it beat on parts count :)
Maybe go back to original design but add in a guide rail that would allow a ball bearing to roll back and forth. What I'm seeing in my mind would cause less waste water thus be able to pump more?
Put rocks in the tube just under the weight it takes to actuate. Less water to fill tube, and faster the action, I think. Your little one might have been on to something. Inspiration could come from anywhere.good work.
Innovative concept. Good job.
I've always thought about the loss of water in these types of pumps and it bothers me. I wonder if there is a way to reclaim the system losses. I'm sure something like this would be useful if you can't get electricity to the pump location, but seems like solar energy and battery storage would be more efficient.
This could run all year, especially when the sun isn't shining in the middle of winter, or in the middle of a forest, or in a cave.
I always think about this same thing with gravity based pumps. But thermodynamics always gets in the way. You can keep going down the rabbit hole but is it worth it? Great design Joe. Wonder if there is any gain on going with a longer stroke out put "pump" and adding a check valve?
This would be a way (possibly) to pump water up from my creek that is 140' below my house, and in deep woods. The "waste" is just water that will continue on it's way to the river. The pumped water would be able to feed my garden without having to use the tap. Fantastic.
Awesome video! Love this stuff! Keep it up & can't wait to see the next video!
So just a question why wouldnt you produce electricity with this pressure and use a small electric pump to produce the pressure you need. You can the bank the water upstream generate electricity, use the run off water down stream using a pump to wheverever. Since you have electricity you can use it downstream. Also when you are not pumping water you can use the electricity to do somethign else. Electric Pumps are very reliable easy to replace , electricity is easily transportable. Also It is easy to produce electricity with water or Solar. These pumps just do pumping but nothing else. And they arent cheap either or fast. Also may be use the water pressure to directly run a centrifugal pump instead of this setup.
Interesting. A ram pump gives you more Consistant flow and may be a little more, I won't say efficient as and waist can be returned to the stream or river you are using as a source, but maybe less wasteful of the supply.
Not to mention the ram pumps are going to be a lot more cost effective.
Still a very interesting concept.
I wonder if you could have 2 pistons on the same seesaw, have one open while the other is closed?
I guess you'd need 2 of those valves, I'm also not sure if that would actually help at all.
or bigger pistons? That's for another video.
Why couldn't a spring be used to pull the piston back instead of the water seesaw?
You lost me but am impressed . Can i use this in the stream to take water up hill?
Good job, it's fascinating though it doesn't look very efficient :)
Here in Denmark we unfortunately don't have many hills.
But you have wind, and they've been pumping water with wind for centuries
Very interesting concept, and it’s great that you got it working. Really cool! Unfortunately, I think it is extremely complex when compared to a ram pump. Meanwhile, ram pumps are elegant in their simplicity, with only two moving parts.
I think that ram pumps can yet be improved upon, and offer many opportunities for further innovation.
I just wanted to see if I could do it.
@@JoeMalovich and it’s brilliant that you did! It’s fantastic. I think you should go improve upon a time tested design now though. Bring ram pumps into the future for us. If anyone can do it, you can, and I know there is much room for improvement in the ram pump designs of today, which have seen only marginal improvements since their invention.
This is how you take your COVID19 lockdown and invent cool things!
I love that mechanism. Did you try pressurized air to store energy?
I did not, The compression ratio would not be good, it wouldn't be able to develop much pressure.
@@JoeMalovich thank you for answering.
I think your design could benefit from a pilot operated valve which would alllow for a much smaller cycler and because of that much less water wasted. Or it might even be easy enough to actuate with your first attempt with the over center lever
Pilot valves like a bunch of pressure to actuate, I fear that my 0.5 PSI or even 6 PSI water source isn't enough, and I don't want to use my high pressure water for pilot actuation because how would I start the pump?
I really like it! I am going to watch again to better understand what is going on. Just wanted to "engage" after the first view.
I saw something like this in the mother earth news. They put a styrofoam float in a 55 gallon drum, when it floated to the top, it opened a valve that drained the drum and the cycle repeated. It was very slow, but constant.
Great project Joe!
Thanks!
Hi Joe, thanks for the good work. I was imagining here having seen the clip, how about if instead of the seesaw mechanism, one used a cam mechanism where say a roller displaced by the sac movement moves round a cam to aid in pressurising the pump. You could try it if it's ok.
It looks slower than a ramp pump but the sound is way better. If i had any flowing water I would place this device near the house.
It is quite slow, the next version should be considerably faster.
Hey Joe, love the videos. Keep them coming. Have a look at the “bunyip” pump. The valve issue is solved and can pump to a huge 200m head (600+ft) on a tiny fall of only 600mm (2ft)
Yes I've heard of them, but they cost like $2000 and ship from NZ. I guess this is like a Bunyip pump in a different configuration. I'll address this in the next video.
Good stuff
So a question, if you use the water drainage off this pump to go into a container and feed that water into another pump that pumps to the feed bucket of the first pump. Would you then have 100% use of the water?
Such an idea requires more pressure then this system is expecting. However if those such pressures where to exist at the head, i dont see why you couldn't run another pump style to move the wastewater back to source. Perhaps even tied into the seesaw as a driving mechanism.
Sorry, but this video told me nothing. A ram pump can lift water say 40 m. How high can this pump lift any water, and from where does the pumping energy come from?
