Excellent, I’m wondering if something like that could be adapted to make in impeller-less pond or lake pump for water aeration. If the entry of the tube were turned into the direction of the shafts spin, maybe it would be self priming.

Great videos Dan! Keep up the great work!! By the way, back in 2015 your video on changing a linear lens to a spot lens, you commented to keep watch for other videos explaining which lens's are the best to use and or brands of TV's. I have been over your videos and I don't see this covered. If you have covered it, can you provide a link to the videos explaining which brands to look for? Much appreciated. Thank you.

Shoot I’m a little late on commenting, I hope you see this.... I have been trying to work on a way to move large amounts of water by pulling the water (similar to how a tree works) instead of pushing water (which all current methods of moving water require). Any thoughts or suggestions on how to create a negative (or low) pressure to which water can flow upwards without the use of engines?

With a siphon you can go up but the exit always need to be lower than the entry point. If the water source is unlimited like an elevated pond, siphons can continue to work with a minor leak or imperfection at the high point in the channel. I have siphoned water over the roof of a building to a bucket on the other side. The start vessel was higher than the exit but on the roof I had a tiny hole in the PVC pipe water dripped out of as some air was sucked in. The result was water on the roof (not much) and a slightly compromised siphon (some air exiting in the lower vessel). Water moved to a higher elevation with a siphon. Wasteful considering the amount of water required but it did work and may be useful for research on what you are attempting to do. There is a limit to the height a siphon can curve over. Adding a water lock that opens and closes would be much more efficient than a tiny hole. Hope this helps. Other than that, without the input of energy up flowing water only works with evaporation = natural heat or input energy.

Thanks for the response. I am curious as to how trees can so effectively bring water up their system, but we can't find a way to mimic this. I have done some research and it seems like its a combination of a couple of things. Chlorophyll acting as the energy transference by taking in and reflecting sunlight. From the energy exchange in the leaf, water from the roots of trees then suck up, or pull up the water through small chambers which are designed to optimize capillary action and bring the water through the whole tree and to be eventually released where the energy is being transferred by the leaf. Seems like a shame we can't figure out how to mimic this system and create something which uses capillary action and exploit energy exchanges which passively (without external energy input other than the sun) to move vast amounts of water up an inclined distance.

maybe by having a solar panel type material act as the initial kick starter to the system, we can then use a heat exchanger water at lower levels to move upwards in a semi liquid and gaseous state to reach the top where the gas and liquid can then condense back down to pure liquid form and then have gravity as the agent for moving the water to the designated location? Idk just thoughts, maybe some day down the road ill have the money and time to research how this can be done...

omg, Dan... you need to scale this up with pvc pipe on an axle with a spigot on one side so you can attach it to a bigger motor and really play with it. how high can you prime the pump and still have it work? priming the pump is adding a little potential energy, and the torque is adding the force to fling the water out BUT the moving water is also creating low pressure so the atmosphere is also pushing the water out. You're sort of cheating physics, no? 2 for the price of one? Can you get the potential energy gained by the elevation of the mass of water to excede the energy of the torque?

Wouldn't just a syphon hose be just as good, for getting water out, all you need is for your water source be slightly elevated from the ending point of your hose, you can go up and down hills as long as there are no air bubbles in your hose and your end point is lower than your beginning point, this method is used a lot in maple sugar bushes, where hoses are used to collect sap from trees and from cisterns used to water gardens away from wells or plumbing! You can add split offs as well, and have on off nozzles, you just have to make sure to keep the air out of the hose's! Some times simple is better! And cheaper, nature works in mysterious ways!

But in all seriousness many scholars said the earth was round even the bible says the earth is round but flat earthers want to say it's a "NASA conspiracy". I even saw one take a lemon pour water on it and said "if gravity exists then water should stick to this lemon, instead it fell on the ground.

Semantics. The current theory of gravity predicts everything we can observe perfectly well. We don't need to know its underlying constituents to see it in action. Just as electromagnetism. We don't know what electromagnetic fields are, but we can use them to build devices like the one you're using to write your doubts about them.

+pgabli10 _I understand the forces he's using the suck out the water ... Gravity has nothing to do with it_ You don't understand the forces. This doesn't work without gravity. A siphon is powered by gravity. The weight of the air on top of the water pushes the water up the hoses. You don't really suck water up a tube or a straw, you lower the air pressure inside the tube/straw and gravity-powered air pressure pushes the water into the void. Without gravity the tubes would just stir the water. How is this known? Equations with a g in them.

Hi Dan. According to this device, this is the most recent video you posted. I'm just trying to track an order I made on August 26th. I can't find an email. I called the number on my email confirmation with PayPal. Do I have to activate PayPal first before it gets shipped? There are only ROBOTS to talk too. Couldn't find a way to email you either. Sent you a snail mail and my letter with my postal money order came back unopened. So I ordered online on the 26th of August. The reason I didn't order online is that I might have to change my account number. This is why I didn't activate PayPal yet. Want this order to be completed and delivered FIRST before I set up PayPal and fix things with the bank. Otherwise I will just have to do EVERYTHING again with the new account number. A lot of unnecessary information - I know - but I just want to TRACK my order so I am sure to BE THERE when I expect its delivery. This is the only means I have to communicate.
