Kelvin Water Dropper Capacitor or Electrostatic Generator

- Shown is the construction and operation of a Kelvin Water Dropper capacitor followed by an explanation of how it works. This is essentially an electrostatic generator. Falling water drops are used to charge a capacitor. So gravitational potential energy is changed into stored electrical energy on a capacitor. When the stored electric energy is large enough, an electric field between two electrodes reaches the dielectric breakdown strength of air and a spark results.
Thankyou. So many other utube explainers skip the critical detail of ions in the water. The penny now dropped. Cheers
Wonderful!
what about using acid? acid has a low pH thus providing more molecules for ionization?
I notice that in vulcanic storm there are more thunder than a rainy storm, due to the amount of ash and powder, so i wonder if this experiment could work using sand or ash instead of water. ? ?
I do not know. Maybe if there are positively and negatively charged particles they could be preferentially accumulated in the different cans.
The energy is not comming from gravity sir. Gravity makes the process happen, but the energy is dependant on how many ions are avaible to be separated and different liquids with different ion concentations are going to be able to provide differing levels of power even at the same gravitational potential energy for the fluid.
If you added salt to the water, that would change your power output. If you used an acid or base, that would change your output, etc....
If you use your example 1 in 10^7 ions in water, there's 3*10^25 molecules in a itre of water. that means 3 * 10^18 potential ions for ionisation.
If this piece of equipement can separate even 1,000,000,000,000,000,000 th of those ions, thats 3 coulombs of charge that could be separated in 1 liter of water.
If you did that and maintained the upper can voltages with diodes you could easily make 100 KV with this....
The energy does not come from gravity.
You need to think more fundamentally. As the ion concentration goes up, there is more electrical force repelling each drop. So it takes more force to pull the water droplets down into the same charged bucket, which is more work, force through distance. If the ion concentration were to get large enough, gravity would not be able to pull the droplets down and it would stop working.
Tanks professor
I have a question.
If you dropped the water in vapor form, instead of a solid stream. Would it be more or less effective?
That is, would more or less discharge take place?
probably less effective, because in the form of vapor, the water droplets will probably go to the opposite charge field and cancel each other out, and even if that doesn't happen, the volume of water that would pass would be the same, so the potential charges would also probably be stays the same. what might increase efficiency is putting more stuff in the water solution, for example using sea water.
@@pedrojorge4684 Well, I know that a superheated channel of air acts as a conduit for plasma. Now electrical conductivity, I can't speak to.
It would be interesting to shoot a super heated stream and see if it can do anything, I suspect that cool 4c water works the best
this is amazing , i will try that
Sooo amazing!!!!
Please Connect a RAM pump in Order to Pump the water Back Up again 😉👍
effect of adding salt? Anyone?
I think they add salt - salt was added to the original leyden jars which is what the tin cans at the bottom are based upon! would love to copy this to see if my understanding is correct!
The presentation is good!
The derivation is incorrect!
What do you think is incorrect?
@@electricandmagneticfields2314 Electricity is caused by the formation of water droplets.
@@emanacio What does that mean?
@@electricandmagneticfields2314 Electric charges separate due to the increase in surface area.
@@emanacioAn increasing surface area would spread the charge out and in that sense you could say the charges are separating but it would not separate positive from negative charges. The positive and negative electric charges separate because of the electric field.
