If someone wants to know why: The energy that comes from this generator comes from the kinetik energy of the water when it is slowed down by the eletromagnetic fields of the coils. The upper coil attracts the Ions and the lower coil repels them, they slow down and their kinetic energy is converted into electricity. I don't claim to have figured it out. I just looked it up since I wanted to know why this happens.

The energy comes from the conversion of gravitational potential energy into kinetic energy in the water. This kinetic energy is transferred to the electrons in the tubing, as dictated by the motor effect, similar to how a magnet does. The way that the tubes are aligned creates a similar effect to a magnet being moved in and out of the tubes, and so current is generated.

This is why it's important to regularly replace the water or coolant in your cars radiator. After being cycled through the engine and cooling system hundreds of thousands of times the static charge becomes stronger and stronger increasing the electrolysis process essentially turning the antifreeze into battery acid which eats away at the inside of hoses, water pump impellers, gaskets, and temp. sensors.
@keithwood6459
@keithwood6459 3 года назад
The energy comes from the kinetic energy of the water falling. As water falls through the charged rings it is not only deflected by the charge. The droplets are also slowed as the droplets themselves take on or give up electrons in their respective opposite fields. So kinetic energy from the droplets is lost to the processes of slowing and charge separation that becomes a self-reinforcing cycle. My own thoughts, I haven't explained it very well. I would be curious if the polarity of their system always evolves the same way. Ideally it should be random with each fresh start of the system, but in reality it would likely be skewed toward one polarity or the other, because of subtle electric field influences in the environment. It would be cool to keep stats on that and see what modifications to the environment are needed to bring it closer to statistically even.

One point not emphasized in the video is that electrons have to flow through the common water pathway, partially backward against the physical flow of molecules. It's that electron flow that ultimately creates the difference in charge between left and right. Gravitational energy is inefficiently converted to electrochemical energy by induction, until electrons in the 'capacitor' jump the gap.

@@shadiester I think it is kind of like a feedback loop. He started off with the assumption that one stream had slightly negative and other has slightly positive charged water particles. These induce their charges to the mesh. Since one mesh is connected to the other stream's coil, it forces the the water in the other stream to take opposite charge. Because of this feedback system, the coils accumulate more and more charge. These coils are in turn connected to the metallic balls. When their is enough potential difference, there is a charge discharge and the coils become neutral. This repeats. This is my understanding.

@@shadiester Let us say mesh 1 is negatively charged which makes coil2 also negatively charged. Because the coil 2 is negatively charged it attracts positively charged water particles and also repels the negatively charged water particles. So the negaticely charged water particles are forced to move upstream into the water tank. This happens against the gravity and that is what is mentioned in the original comment. Also what is not shown in ths video is that the two water tanks are connected through a metallic wire. So the negatively charged particles which were repelled by coil 2 flow back up and come through water stream 1 thus making the mesh 1 more negatively charged

I guess, if the water were purified H2O (or "distilled water"), it would not produce any charge, but in normal water, there are always other types of atoms present, which exist in a state of ionization, being partly bonded to the water molecules, like if you put salt into water. If I remember my school chemistry correctly, that becomes Na+ and Cl- molecules which bond to the according side of the water molecules. That can only happen because water is a dipole molecule, it has one end that is positively charged and an other end that is negatively charged. So these ions will cross the charged wire mesh and then lose their charge. Because the water has before flown through the metal rings with the opposite charge of the wire mesh, the effect increases itself.

Seegal Galguntijak When people say pure water is not conductive, it is because there are no ionic pollutants. Stuff like table salt (NaCl) would dissolve and conduct electricity. As such, pure water wouldn't function as a wire in that sense. In this case, it is less electricity than it is electrostatics, as far as I can observe, so it functions based on the fact that water is bipolar so it can separate charges.

The gravity is driving the separation of the charges. If it weren't for the gravity pulling the water down into two separate streams, any charge variations would just attract each other and almost instantly cancel out again. You'd constantly have tiny electrical fluctuations popping up and then going away. However, the gravity pulls the water down and overcomes the attraction of those charges and rips them apart from each other to drive the whole system. Look at how the upper coils attract the water streams due to the opposite charges. Those coils don't contribute much to the overall energy since they are pulling perpendicular to the water flow. However, the bottom screens have the same charge as the water and are directly in line with the direction of flow and will be repelling the falling water. If you were to carefully measure the speed of the falling water, you would find that the bottom screens reduce the falling speed of the water by approximately the same amount as the energy being built up before each spark.

EE Ehrenberg I have actually run across Kelvin's waterfall before. However, understanding it has less to do with raw knowledge and more to do with how you approach the problem. Derek loooves complicated looking problems. There's usually a lot of extra stuff that looks like it might possibly drive things but is actually just part of the process. A lot of real engineering problems tend to act like this as well. The key is to step back and not get bogged down with the details of all those coils of wire, etc. Instead, look at the overall process and try to figure out where the energy comes from. It can't be the metal coils or screens - there's no wires or radio waves putting energy into them. Therefore they *can't* be the source of the energy driving the system. instead, we do have a clear driving force, the gravity pulling the water downward. Now that we know that it's gravity driving the system, we can work through it step by step to figure out how that gravitational energy can possibly be converted into the electrical energy that's generating the sparks. The secret is that most physical systems are actually fairly simple if you step back and analyze them piecemeal like that. And since there always has to be some sort of energy input, that is a logical place to start.

The system's electrical circuit is driven by the EMF created when electrically charged water falls from the top basket's voltage, to the bottom basket's voltage. This EMF induces current oppositely directed: up on one side and down on the other side of the apparatus, thereby charging the discharge balls capacitance untill they discharge ionically thru the air, completing the circuit.

The energy comes from whatever makes the water move. The electrical field of the two upper coils polarizes the water between them, but the positive and the negative part still attract each other and would stay together if it was not pushed apart by force. Under normal circumstances it would be gravity, or potential energy of the water in gravitational field which gets depleted as the water falls down. But the machine could be reproduced also upside down or in microgravity conditions such as on ISS - in that case other source of energy pushing the water through the machine would be the source.

@SSGranor
@SSGranor 10 лет назад
The water starts out electrically neutral. There is no significant electrostatic potential in the water until there's charge separation, which is caused by the charge building up on the coils. That, in turn, can't happen without a source of energy, as like charges will tend to repel. The only available sources of energy here are gravitational potential energy and thermal energy. Given that the droplets are moving relatively fast when they hit the mesh, their overall kinetic energy, rather than internal kinetic energy (a.k.a. heat) should matter more. But, the motion comes from the conversion of gravitational potential energy as the drops fall. Thus, the only thing that could reasonably be the energy source here is gravity.

Instead of just making a spark, attach it to the Tate Ambient Power Module circuit (bridge-rectifier made from germanium diodes rated for high voltage). The module converts to DC and charges capacitors, thus smoothing the power. If the capacitors are say 1000MFD or higher, this can drive something conventional such as a battery charging circuit for a cell phone (voltage regulated to 5V). But, you have to have constant water flowing, and if you want the water to go in a circle, you need to pump it UP again. I suggest you use the Tesla Water Fountain patent number 1,113,716. The idea is to spin the water at low power, rather than pump it. Create a water vortex, the water level rises and spills over the edge. Now you have falling water that you can separate into two columns.
@daniellapain1576
@daniellapain1576 Год назад
Big brain time! I think that the better option is to run a spark plug that can handle the voltage. Create a siphon that leads to the spark gap and tune the system to keep up with dripping water. If you hit a water droplet with the 10000v then the water droplet can ignite and explode. That energy splits the molecules so fast that it ignites the hydrogen and burns the oxygen. You could then run a piston chamber with that energy. The only issue is tuning the system to run an engine like this and power a generator. It's an idea that has been stewing in my head for a while. I don't have any resources to pull it off or the money to try it. One day maybe.

@Escekar
@Escekar 3 года назад
A charge is created by the dipoles within the water droplets. Each droplet has a fluctuating liquid diode preventing the water droplets from flowing upstream. This creates a positive flow in one direction. The mesh interaction creates a wave like function which is emulated in the adjoining coil. Having two separate coils receiving droplet harmonics from opposite streams increases the wave harmonics. The two metal balls resonate this harmonic and enable the wave function to collapse. When the wave function collapse or cancels out they annihilate the harmonics resulting in a micro-discharge. We see this as the little blue/white spark of electricity.

Instead of 2 streams, suppose you have either 3, 6, or 9 streams. Tesla seemed to like these numbers. With 3, arrange them in a circle. The bottom coil attaches to the top of the next going around. Three balls will be under each lower section coming to an upsidedown apex. The sparks should go in a circle. Instead of a spark, pulse thru a coil to make a temporary magnetic field in rotation. A motor. Attach a giant beater, and spin this in chocolate, like in Charlie and the Chocolate factory.

An engineer might explain this phenomenon via a concept called positive feedback. The apparatus is designed in such a way that the longer it runs, the better it works. In this scenario, a minuscule difference in the electrochemical potential in the water sets off a runaway effect that allows the apparatus to collect nearly all of the inherent electrochemical energy in the water. An interesting consequence of this design is that the "positive" or "negative" assignment on either water stream is essentially random. It could change every time the apparatus is turned on, and it will work in exactly the same way.

Great explanation describing its instability. but where does the energy come from. Short answer is gravity. Consider like and opposite charges. They respectively repel and attract. A closer look at the whole process reveals that for a short distance water is pulled towards or accelerated by the charge separator loop. After it passes the charge separator loop, water is slowed down because of its attraction to the separator loop, and slowed down again with the collector plate because like charges repel. It takes energy to slow falling water, and it has to go somewhere. It ended up stored as an electrostatic charge potential.

@danheidel
@danheidel 10 лет назад
Calin Agotici No, it is the gravitational energy that is driving the whole thing. Here's the steps of what happens: 1) Random charge variations cause one loop set to gain a net charge. 2) The induced dipole causes a greater charge separation to start forming. However, without any external driving force, those charges would simple recombine due to electrostatic attraction. That's why putting the structure into stationary water wouldn't work. you'd constantly get tiny charge separations but they would almost instantly self correct and vanish. 3) Gravity pulls the water into two separate streams, preventing the separated charges from simply recombining. This takes energy out of the gravitational fall of the water. This is caused by the repulsion between each charged water stream and the bottom screen of the same charge. You see the same effect on the top coils. They visibly deflect the water in an attractive way but since the attraction is at a right angle to the direction of water flow, it has a minimal energy contribution to the whole system. You can't see the screen/water repulsion as easily but if you were to measure the speed of the falling water, you would find that it is decreased as it passes through the screens. You can never get energy for nothing. The electrostatic interactions cannot drive the system since there is no way for net energy input to occur. The only energy input is from gravity pulling the water down. (or more indirectly, the pump that is circulating the water back up to the top) When analyzing energy systems, you always have to step back away from the details and ask yourself, "Where is the energy driving the system coming from?" Once you figure that out, then you can work your way through the problem.

I was thinking that the relative deceleration and acceleration of the water on the top and bottom of the mesh would impart differing amounts of work on the falling water but that is not the case.

The separated charges have electrostatic attraction to each other and overcoming that attraction must be where the actual work is being done.

Some of the water droplets kinetic energy is lost in the process.

The way I understand water, it has a slight tendency to seperate in H+ and OH- ions which are constantly reassociating back into H2O and then disassociating back into H+ and OH- ions. The small percentage of water that is temporarily in these ionic forms are the charge carriers that are attracted to the corresponding oppositely charge coils through which the water is flowing. When enough of the positive and negative ions are attracted near the coils there is a small flow of current in the coils which results in the coils themselves taking on positive or negative charges. When the charges are sufficient to ionize the air between the balls, a spark jumps the gap and the charge is neutralized at which point the process starts over again.
@Lemonickous
@Lemonickous 10 лет назад
In the end it has to be gravity right? The whole system is just a positive feedback loop, that relies on the charges on drops along with the need of drops to be small enough for this positive feedback to work (as in bending the stream of drops you want), and so we get to the mechanism that creates these drops, which uses just small holes, where water goes through and there is some force that is overcoming it's surface tension, thus supplying required energy to break it into the drops we need. This force is gravity, so the energy is coming from grav. pot. energy. Yes?
@Lemonickous
@Lemonickous 10 лет назад
Calin Agotici I checked out your answer, but you're wrong because you're not explaining where this net electrostatic energy is coming from. We all understood that these ions are causing the metallic bobs to get charged and everything, but without gravity doing the work of dividing the water into these droplets, the net charge built up on the sieve would not be substantial to produce this phenomenon (because of zero net charge). The energy used to produce these droplets is the crucial factor.
@12tman12
@12tman12 10 лет назад
Le monickous It's also kind of a mix. The energy comes from the ions in the end (the spark), but you need potential energy of gravity to run what's basically a sorting machine into two containers with different charges (then the spark) but it's using very very little (why the machine is so inefficient). But if you had zero ions, even with gravity the system doesn't work But once you start getting very specific, it comes down to definitions. As in the energy created in hydro dams and turbines doesn't come from the potential energy of water, but the heat of the sun. As it's the heat of the sun that evaporated the water which then turned into rain at higher altitude that filled the dam that has the potential energy to run the turbines.
@Lemonickous
@Lemonickous 10 лет назад
Yes, viewed from the point of view of the metallic contacts, the source of energy might be the charged droplets transferring this charge to the metal. But the charged droplets existed -because- work was done in pushing them through a mechanism that converted them into drops. Otherwise, if it was kept as a bulk of water, it would not have had an appreciable charge to it. Now, this work, was done by gravity. If you're gonna attribute sun for energy, you might as well do that for 90% of things happening on earth. As to why the mechanism is so inefficient, it's because due to firstly, not all charged droplets have same charge, so literally most of them are wasted by cancelling each other out, that creates the inefficiency.

H2O by nature is a non-ionic compound meaning that it shares no overall charge despite its polarity. Hence, if this experiment were conducted using pure (distilled) water, I do not think a charge could be produced. The concept of 'hard water' (contains impurities) would suggest that the water falling past these coils contain ionic elements such as metal particles for example. Whilst most of the water travelling through these coils would be in fact, water, a small percentage could contain these ionic compounds or elements, hence the small charge produced. These ionic compounds being of different charges would then be attracted according to the overall charge of each coil producing static electricity until discharged.

Thanks for the recommendation youtube. This video from when "The Hunger Games" was relevant was actually really cool! I would love to see more videos about making similar setups more efficient.

You would generate more power from the kinetic energy stored in the water if you ran it through a small turbine attached to a alternator. Very cool

Running the water through a turbine is always going to be orders of magnitude more efficient for power generation.

The electronic, mechanical, or manual lifting of the water puts energy into the system that can then be taken partly for electrical energy

The answer to your question is gravitational energy.
@MrSmitheroons
@MrSmitheroons 3 года назад
The energy is harvested by creating order and separation out of what would be randomly (somewhat evenly) distributed ions or charges in the environment, mostly in the water I'd think. The energy isn't created, but moved around in the system. Using a passive system with just conductors and nothing else, to magnify biases in charge, is what makes this setup so cool.

It's only renewable if you're using natural waterfalls, and not pumping water like in the experiment.

Nope. It's highly inefficient, and there already exist better ways of taking advantage of falling water.

The energy comes from the gravitational potential energy as the waterfalls. Gravitational potential energy --> Electrical potential energy.

Where is the energy coming from? The grid. The grid supplies the power to the water pump, that lifts the water against the force of gravity. ;)

Roughly 271,240 years, a 2000 mAH phone battery holds around 29 kilojoules of energy, divide that by 6.5 to get 4.461 KJ per year divide 1210000 by 4.461 to get answer. Your better off time traveling the normal way.

Forever. Watts is a unit of power. Power is energy discharged per unit of time. In this case, 1.21 GigaJoules/second. Your question is the equivalent of asking someone to calculate how long the turtle will take to go 200 mph. The turtle doesn't produce that kind of displacement/second, regardless of how much time you give it. and likewise, the device, at the scale shown, will not produce that much energy/second REGARDLESS of how much time you give it. The turtle maxes out at about 1/4 mile/hour and this devices maxes out at about 1 femtojoule/second = 1 femtowatt. This thing produces about 1 femto-watt (about 10^-12 watt) You literally get more kinetic energy from the falling water than you do from the electricity produced.

@@RockGeek00 Wrong. You're calculating the accumulation of energy, not the RATE of energy production, which is what *any* WATTAGE rating requires.

@k.chriscaldwell4141
@k.chriscaldwell4141 5 лет назад
Gravity is the source of energy. Gravity by way of its pull on the water causes the electrical imbalances to form. No gravity, no fall, no electrical imbalances, no flow of electrical energy, and no sparks when the charges rebalance. Gravity, my dear Watson. Gravity.
@kaelruland2190
@kaelruland2190 5 лет назад
Not even close. This same configuration would work in zero gravity as long as there is enough water pressure to move the droplets through the air. The energy comes from the breaking of hydrogen bonds as the water is forced through the shower head into droplets.

I’m not sure if you mean where the energy comes from or what it turns into, but basically the gravitational potential energy gets converted into kinetic energy as the rain falls. I’m guessing the rainfall would actually slow down a tiny bit as it passed through, converting some kinetic energy into electrical potential energy
