Tesla's own schematics for the Hairpin Circuit
Nikola Tesla, the first person to seriously study Radiant energy more
than a century ago, built a simple circuit to generate radiant energy
so that it's effects can be readily demonstrated. You MUST have
a look at this as it goes against everything that we have been taught
about electrical energy.
The Tesla Hairpin Circuit in action
Hairpin Circuit Demonstration Video
Karl Palsness has posted on his YouTube page two videos demonstrating
the Tesla Hairpin Circuit in action. This clearly shows effects
that cannot be explained using conventional physics/electricity:
Lecture given at the 2009 Alternate Energy Partnership Conference (AEPC
On May 30, 2009, Karl Palsness gave a lecture at the 2009 Alternate
Energy Partnership Conference held in Waldorf, Maryland. This lecture
away and brought the house down!!!
It has been graciously posted on YouTube in 10 parts thanks to Spodie
Some articles by Nikola Tesla related to the Hairpin Circuit
With Alternate Currents of Very High Frequency and Their Application
to Methods of Artificial Illumination - PDF version, Word version
Lecture delivered before
the American Institute of Electrical Engineers, Columbia College, N.Y.,
May 20, 1891.
Note: This first lecture does not talk per say about the hairpin circuit
but gives important background information that should be read before
moving on to the next article.
As most versions of this lecture out on the internet contain many typos
and even errors, I have proofread it
corrections based on the printed version of the lecture found in Lectures,
Patents, Articles published by the Nikola Tesla Museum in 1956.
- Experiments with Alternate Currents of High Potential and High Frequency
Lecture delivered before the Institution of Electrical Engineers,
London, February 1892.
Note: This second lecture also does not talk about the hairpin circuit
but gives important background information.
- On Light and Other High Frequency Phenomena
at the Franklin Institute,
Philadelphia, February 1893, and National Electric Light Association,
St. Louis, March 1893.
There are some discussion threads where the Hairpin Circuit is being
discussed. It is a great place to get your questions
answered or gain additional insights:
Closeup pictures of the Hairpin Circuit replication
For those who are curious to see close up pictures of Karl Palsness'
Hairpin Circuit replication used in the videos, here are closeup pictures.
For most of the images, if you want a higher resolution version, just
on the picture.
10,000V AC Transformer
In the demo, a 10,000V AC, 23 M.A. furnace ignition transformer is used.
Each pole of the 10,000V AC transformer is hooked up to the bottom of
one of the capacitors (green wires) which then also hooks up to each
side of the spark gap (orange wires)
Connection of the wires to the TDK High Voltage
Ceramic Strontium Titanate Doorknob Capacitors (High Current / Quick
2000 pF - (2 1/4" x 1 1/4" high)
The spark gap electrodes are comprised of carbon welding rods mounted
on two screws so that the distance between the electrodes can be easily
The two 3/8"x48' copper rods are held in place by supports on the wooden
stand. If you notice, they can easily be removed so that the copper rod
be easily changed and/or permit the removal of the sliders.
A few more pictures will be coming soon.
If you decide to replicate this circuit, use extreme care. Improper
experimentation with high voltages can kill you! When you see Karl and
others touch the Hairpin Circuit or bulbs, it is a part of the circuit
where radiant energy is present but where there is NO conventional electricity
the top part above the capacitors contains radiant energy only. Below
the capacitors, it is regular 10,000 volts AC which can cause serious
injury and even death.
to replicate this at home unless you have a good understanding of
high voltage currents and how Tesla designed the circuit. Also, do not
run the circuit using low voltages as the behavior is different.
