This time, I will review the popular YouTube videos.

These days, even if it's good to watch on YouTube, sometimes people skip it or don't watch it if it's too long.

When you watch Youtube, do you scroll and read the comments first?

To save your busy time, why don't you check out the fun contents, summary, and empathy comments of popular YouTube videos first and watch YouTube?

Ri*************:

I was going to suggest smaller spheres or needles for the spark gap to increase spark length, however after watching a second time I noticed @ time 1:40 and 2:16 a smaller spark gap electrodes configuration. having seen other videos on Kelvin's t. with 1/2" balls and or just bent wire . It doesn't seem that large spheres rings up a higher voltage, as does the top load of a Tesla coil. Have seen a lab spec. for measuring voltage where the dielectric is air is: 1/4" needle to sphere @ lab temp/humidity = 10 kv

Sy*****:

What does this have to do with the hunger games exactly?

Sq**************:

Can someone calculate how long this contraption would have to run to generate 1.21 Gigawatts.

fa*******:

Ok turn it into a pyramid and bam...history myth busted

Re************:

I bet that even the sound energy it's producing is greater than the electrical energy ;)

Answer/spoiler to the question:

The energy is obviously from the potential energy of the water. So what ever lifted the water above, is the source of energy.

Ja***************:

I tried to replicate this experiment in my barn for a middle school science fair project. Only produced a barely detectable charge and lost to a girl who showed that different colored dye absorbs into paper towels at a different rate. #christianschool

Pa*************:

From the potential energy of water stored in that tank.

Mi*******:

This may be how we will eventually travel through space with disk-shaped craft built like a parallel plate capacitor and using the research done by Brown. If instead of the two balls shorting out adjustable insulating distance between the plates it would continue to charge to a high voltage and work like the lifters. You would just have to stop on a planet with water and refill your tanks.

Th***************:

Stranded on a deserted island with a dead cell phone, some metal coils, a stream, and 6-7 years, I got this!

Ju*********:

Charge on the metal
Hydronium ion of water
And induction responsible for this effect.. I hv seen this experiment at MIT

Gh**************:

Hook this up to a hydroelectric dam and increase it’s efficiently slightly!

Pa*****:

I read the title as Kevin's Thunderstorm and I just said "Dammit, Kevin"

di*********:

I made one of those for my 8th grade science project..got 3rd place ...in1969

Th*****:

i've got a stupid question: the setup looks symmetrical; but one side becomes negative while the other becomes positive. How does nature decide?

Is it one of those deals where a tiny fluctuation in the charge of the droplets at the beggining baloons into a macrospic effect? in this case, would one side be negative once, only to become positive in the next cycle?

Or is there a diode somewhere that forces the charge to flow in a certain direction and determines which side is positive?

De*****************:

Veritasium, I wish we could test this in NASA's vacuum chamber with less than 50 torr (<1psi) vacuum. If we can keep the liquid chilled we could go as low as 20 torr.
There is a mixed crowd over what is the cause of this effect. Many claim it is the kinetic force of a conductor moving across the coils, other believe it is a static friction force with the air building up a static potential. I would like to see the effects with saline water and pure water in a vacuum chamber to test the two theories.

le*******:

It comes from potentiel energy. Gravity does all the work. The speed of the water is slightly reduced as if it was falling freely.

Ph******:

It's not the current that kills you, it's the ENERGY. :)

wa******:

I think the energy comes from lifting the water up above the coils

St*****:

You even look like a mad scientist. WTG!

pa******:

Positive feedback system, with the energy input from the falling mass of the water. And the water acts as a charge carrier, moving charge, thus current.

Now picture this occurring on a vast scale miles wide, and the thing filled with convection columns many feet across replacing the coils... And then you're basically outside during a thunderstorm.

Il******:

I liked this real Derek version 10 times better than the fake Hollywood version :)
The other video was well made, but it was just not you.

se******:

I want to know the answer, not learn from the comments. I hate when you do this.

An*************:

I am here because of ElectroBOOM, where he dissed (a little bit) Derek about the "current" that kills you.

Ca************:

This video has so much 'wow' to it. Especially in the internet address...

sp********:

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.

FP**********:

Heh video response, anyone remember when those were actually a thing?

Al*********:

So if I drink the positive water... Will I be positive???
Just asking for someone

Fr*******:

MAGNETS!! \o/

Or the "water" is really "unicorn piss"?

;-)

Wo********************:

While there's not a lot of charge, this is a brilliant setup. I see potential (no pun intended) in this. Perhaps a large enough setup - or an array of rigs - could be used to drive LEDs as some sort of emergency storm lighting. Or... I don't know. But I'm sure there's greatness that could come from this.

Ca******************:

The electrical energy comes from the fact that water must flow from a high point to lower point. There must be movement in order for the apparatus to function. This gravitational potential energy is ultimately converted into electrical potential, which is the voltage.

Da*******:

It is really annoying that he did not put the two balls more apart in order to create a higher charge and make the visuals a lot more interesting.

Wi***********:

Don't cross the streams.

Ad****:

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?

ka****:

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.

Be******:

I wonder
what happens if you surround the waterfall with an insulating tube (like an open ended cylinder of thin glass as big in circumference as the shower head). Attach the top of the tube to the shower head itself so that water can't go around the cylinder. You could also then wrap wire around the cylinder itself (to get closer and more coils). And, modify the inlets to the shower heads so that there is a pool of water above that feeds both shower heads. That way the water in the inlets will be self segregating as well.
