"Sweet Home Alabama" - Musical Tesla Coils

These are two gigantic solid state musical Tesla Coils. A Tesla Coil is a special type of transformer invented by Nikola Tesla that is able to generating extremely large voltages using a phenomenon known as electrical resonance. Each coil in this video is capable of generating a 13 foot spark. This equates to about 500,000 volts of electricity.


The primary drive system for the coils consists of high power semiconductors arranged into an H-Bridge switching configuration. During a spark event, the coil is pulsed on for a few hundred millionths of a second. During this short time, thousands of amps circulate within the primary tank circuit and the energy is coupled into the secondary resonator through magnetism.


So what appears to be a continuous burst of sparks is actually a specific number of sparks generated per second. By modulating the number of sparks that emit from the coil each second, different tones can be produced by the coils.


These coils were constructed by Eric Goodchild and Steven Caton.

how could someone dislike this. its like disliking awsome

[Eric Goodchild]

You basically have to be so boring that nothing gets you excited in life or you think it's fake,

That generally sums up the people that disliked this video.

[Johanas McFaggot]

the electric company will shit a brick

[johnny71c]

fantastic I wouldn't mind one of those

[Pete Raw]

brilliant!

[KRC1023]

Lick! It! Lick! It!

Just kidding...

[KRC1023]

No kidding...

No, this is not free energy. There is no such thing as free energy. As of today, science has so far discovered that the universe consists of mostly dark energy, dark matter, and then actual matter. Actual matter being only about 5 percent. Energy is never free, it just changes form. Also, most physicists believe that energy can be classified into positive energy and negative energy, and the sum of those parts is zero. This is called the zero energy hypothesis.

Ehhhm, such a Tesla Coil stand alone cost a fortune if you can't build one yourself, not speaking the time it would take to build this ... like weeks if not months I guess ..

worlds best gug zapper

[jonny woods]

how fucking scientst get their shicks

[daniel Quillope]

Wow Pretty cool but can you make a video of showing how did you do it?

[TheSurgeon98]

Hopefully "Damn, I have an awesome neighbor!" Because that is damn fine work sir!
