This is a Tesla circuit that I saw first in Karl Palsness's videos on the "Hairpin" circuit.

Instead of using 3/8 inch copper rods, I used 1/2 inch diameter aluminum rods from Home Depot, which are much cheaper than copper rods.

The spark gap rods are 1/4 inch carbon gouging rods that are copper coated I got from Airgas (50 for around $14.)

Using 16KV, 750 pF capacitors on both sides of the rods, I'm able to light a 75W halogen bulb under water without getting shocked, if I touched the terminals of the bulb.

The transformer is 10KV, at 23mA, don't try this experiment unless you know how to handle it.

  • Awesome replication, really an interesting device.

    Any idea at what frequency it is discharging?

    If you have time, try to find out how many lamps you can connect on the same position on the bar and if they'll dim when lamps are added.

  • My oscilloscope probes probably can't handle the high voltage so I don't know what the actual frequency is. I had some high voltage probes but they got burnt up from my Gray circuit I did years ago.

  • I'm pretty sure they will dim, the more lamps I add to it. Maybe slightly, but the reason I know is because when I short the two bars, I notice the bulb dimming. I got my 2000pF caps...should make another video soon.

  • Ever tried charging a battery with Cold Electricity using Negative Dipole Antenna (Tesla Capacitor). To make a dipole antenna just get 2 rolls of aluminium foil & 2 rolls of contact clear plastic film then unroll each foil roll onto the sticky side of the contact film Then you take these 2 aluminium/plastic films stack them & roll up like a coil and connect each film to each battery contact. Cold vacuum state Electricity draws charge from space & adds charge to battery. See ilav1m8y channel expl

  • the gap in tesla's design, is that just 2 capacitors or 4, because i can't tell. also what are you using as a power source?

  • Man you got some balls.

  • Greetings!

    I tried 470pF caps, too small. Please tell where you find HV caps in Ukraine? Maby give a link. I would be very greatful!

    Thanks for video!

  • @coldarc Perhaps it's the language barrier but I don't think you understand the circuit correctly. The bulb is actually connected in parallel across the filtering capacitors, which are also parallel with the spark gap. Those caps, in that specific geometry, filter out ALL electrons, and only a potential field (displacement current) forms across that portion of the circuit, including the bulb.

  • paralell coupling is still 50% ineffiecient

    since the acceleration of electrons spark gap is moving in serial with the bulb

    where the other halved is moving directly trough the bulb, and you loose some

    of the energy.

  • the guy in the video has just proven what i thought all the time, the light bulb

    is connected in serial with the spark gap that light it up with pure electron charge.

    the bulb act like an independent circuit as the spark gap form an open circuit.

    the same thing benjamin franklin did with his kite trough a lightning strike

    magnetising an iron key

  • Question: If the di-electric in the capacitors was stronger than the di-electric of the spark gap, then we would still expect to see the hot current pumping through the spark gap, even with the bar shorted across the poles, correct?
