Abstract
Nikola Tesla was an inventor who is best known for his contributions for the design for generating alternating current,
Electricity supply system etc. He obtained around three hundred patents worldwide for his inventions and some are hidden
in patent archives. One of the patents that discussed providing free electricity is “Method of utilizing radiant energy” was
successfully demonstrated but was never completed.
Aer careful reading Tesla’s articles and patent application; design of electronic circuitry for the free electricity can be
constructed. Although, there is no obvious reason to generate kilowatts of power through simple circuitry. is paper gives
insight and review of Nikola Tesla’s free electricity invention.

Introduction
One of the Nikola Tesla’s attempt to provide every-
one in the world with free energy was his World Power
System, a method of broadcasting electrical energy with-
out wires, through the ground that was never nished,
but his dream of providing energy to all points on the
globe is still alive today [1].
Tesla’s intent was to condense the energy trapped be-
tween the earth and its upper atmosphere and to trans-
form it into an electric current. He pictured the sun as
an immense ball of electricity, positively charged with a
potential of some two hundred billion volts. On the other
hand, earth is charged with negative electricity. e tre-
mendous electrical force between these two bodies con-
stituted, at least in part, what he called cosmic energy. It
varied from day to night and from season to season but it
is always present [2].
In 1931 Tesla announced in e Brooklyn Eagle that
"I have harnessed the cosmic rays and caused them to
operate a motive device. More than 25-years-ago I began
my eorts to harness the cosmic rays and I have succeed-
ed. Electric power is everywhere present, in unlimited
qualities. is new power for the driving of the world's
machinery will be derived from the energy which oper-
ates in the universe, without the need for coal, gas, oil, or
any other fuel".
e real reason Nikola Tesla for interest in free energy
was he learned that there was warming of the planet caused
by natural and manmade sources of atmospheric pollut-
ants. Tesla may have been rst human to learn that now it’s
called “Global Warming” and “Greenhouse Eect”.
Aer many years, in 2003 a company named Tesla
Motors was incorporated by Martin Eberhard and Marc
Tarpenning named aer Nikola Tesla, the company
was to commercialize electric vehicles using an AC mo-
tor which was built on the foundations of a design that
Nikola designed in 1882. In February 2004 Elon Musk,
co-founder of PayPal, invested in Tesla and became the
Chairman of the company. Tesla Motors have created
several electric cars all of which save on energy costs and
help the environment by producing zero emissions. In-
stead of gas stations, Tesla cars can be recharged by using
any of a number of free charging stations, Tesla owners
can simply plug their cars in and in around 20 minutes
completely recharge their car, shaking up the motor in-

dustry and upsetting fuel providers. e journey to Ni-
kola Tesla’s dream of free energy for everyone has come
to another major checkpoint. Elon Musk announced
Tesla Energy, a battery system that stores electricity from
solar panels and can power homes and businesses. ere
are two products, the Power wall and the Power pack.
e Power wall comes as a 10 kWh or 7 kWh unit and
can create networks that can be used to store redundant
power or ultimately enable homes to eliminate the need
to be connected to the power grid [3,4].
Radiant energy
e electrical, radiant, energy throughout the uni-
verse, which Tesla referred to and would use to provide
power wirelessly of all the inventions and discoveries of
Nikola Tesla, stood out with greater potential benet
to the whole of humanity and his discovery of Radiant
Energy. Only aer conducting exhaustive experimental
trials for three years, did Tesla announce this discovery
in a paper published in December, 1892, entitled "e
Dissipation of Electricity" [5].
Radiant Energy is always there in our atmosphere.
Radiant energy includes solar radiation from the sun, as
well as cosmic rays from the stars. New and varied free
energy devices harness this power to produce electricity
[6].
Static electricity
We all have been subject to static electrical charges
aer we do our laundry or if we scu our shoes on a rug
too much. ere are ways to harness it [6].
Working Principle
From the electric Potential that exists between the
elevated plate (positive) and the ground (negative), en-
ergy builds in the capacitor, and, aer "a suitable time
interval", the accumulated energy will "manifest itself in
a powerful discharge" which can do work. e capacitor,
says Tesla, should be "of considerable electrostatic capac-
ity", and its dielectric made of "the best quality mica'', for
it has to withstand potentials that could rupture a weaker
dielectric.
Tesla gives various options for the switching device.
One is a rotary switch that resembles a Tesla circuit con-
troller. Another is an electrostatic device consisting of
two very light, membranous conductors suspended in a
vacuum. ese sense the energy build-up in the capaci-
tor, one going positive, the other negative, and, at a cer-
tain charge level, are attracted, touch, and thus re the
capacitor. Tesla also mentions another switching device
consisting of a minute air gap or weak dielectric lm
which breaks down suddenly when a certain potential is
reached.
A certain device consists of a long electric wire (about
100 m) that is suspended a few meters above the ground
(possibly by a tree or wooden fence), and not in contact
with any other conductors.
Static power device
Below are some points to be consider for Tesla’s cable
for a long wire
• e wire must be kept from touching any conduct-
ing material. e length and height of the wire deter-
mines the accumulation/rate of the charge, and the
wire must remain sti at all times.
• Once laid out, the wire must be attached to a few dif-
ferent components such as a spark plug, a condenser,

energy. at could produce articially such a "sink" for the
energy of the ambient medium to ow in be enabled to get
at any point of the globe a continuous supply of energy,

A circuit diagram was created based on the Nikola
Tesla’s “Method of utilizing radiant energy” Figure 4

diodes and a capacitor which is a bridge rectier.

positions and earthed at certain points as well.
• e wire will absorb electrostatic charges from the at-
mosphere which is then guided by the other compo-
nents to the battery which stores these charges.
• is stored charge can be used anytime to produce
electric current. is process is a continuous one, as
the wire keeps accumulating charges all the time.
• e extent of the amount of electricity produced de-
pends on the weather as well. A windy day, week or
month will increases the eciency, whereas a humid
atmosphere reduces the eciency of the system.
• is method is similar to the method for collecting
T.V. and Radio waves for electricity [7,8].
Nikola Tesla’s patent “Apparatus for the utilization of
Radiant Energy” (US000685957) shows that how radiant
energy can be captured and can be converted to electric-
ity (Figure 1).
According to Nikola Tesla, energy cannot transfer
across it except through a channel O, in this enclosure a
medium were maintained which would have little ener-
gy, and that on the outer side of the same there would be
the ordinary ambient medium with much energy.
Under these assumptions the energy would ow

In Figure 6 the long coaxial cable acts as an antennae
and a capacitor and as it builds up charge, it discharges
spark that jumps the gap, is then stepped down by the
coil, and then pulsed to the battery through the use of
the capacitor.

For the demonstration purpose four diodes (RL 207)
and one capacitor (200v-220 micro) and one insulated
plate antenna have been used. Figure 5 shows the con-
struction of a circuit diagram using four Zener diodes
and a capacitor which is a bridge rectier.
For the demonstration purpose four Zener diodes

for electricity. Only one time payment for Tesla’s Anten-
na, Tesla’s cable and one can generate signicant amount
of power for charging the invertor.
Few of the advantages of using Nikola Tesla’s method
are:
• Clean, economical, safe and convenient source of energy.
• No tailpipe emissions.
• Pollution free power generation.
• Simple construction, mature technology and easy
maintenance once it gets into production.
• No manual work necessary during generation.
• Energy available all year around.
• No fuel transportation problem.
• No consumption of any fossil fuel which is non-re-
newable source of energy.
• Produces no waste or greenhouse gases.
• Lower maintenance.
• Maximum utilization of energy.
• Works better when recharging battery.
• Most importantly it’s Free, sustainable and can also
provide electricity to remote places.
Disadvantages
One of the disadvantages is if one has to generate
more power; broadness of antenna, and height of receiv-
er should also be increased.
At this time thousand watts of power cannot be gen-
erated from the given above simple circuit. But given the
fact that if there is a tower that can be as high as Warden-
was invented by Tesla and is a small Tesla coil,) it is then
charging the battery where it is transformed via a square
or PWM wave at low frequency and is the reactive power
that charges the battery.
Coax cable
e end of the coax is taped o and the end that is
attached to the spark plug the wires are twisted together.
e rate of charge in the wire that is oscillating in
nature at one frequency and the discharge frequency in
sharp DC transient pulse to the battery that is at its own
rate. Pulse rate would almost look like a triangle wave
attened o and would follow the gravitational wave fre-
quency of about 8 KHZ.
Applications, Advantages and Disadvantages
Applications
At this time, it may not generate Kilowatts of power
for household or industrial purpose but if the circuit is
improved by using Zener diodes with respective resis-
tors, capacitors (as shown an example in the Figure 5)
and if broadness of Antenna and height is increased then
there is enough power can be generated to charge an or-
dinary invertor battery continuously.
If properly designed and connected to the invertor it can
light one ordinary tube light, one ceiling fan, one laptop and
one wireless modem which can run on invertor and inver-
tor charges continuously with the radiant energy.
Advantages
e major advantage is that there is no recurring fee

tries.
• For high power electricity large and broad insulat-

can be installed on the towers for commercial purpose.
Hence signicant amount of continuous electricity can
be generated to charge battery continuously.

clye Tower then some signicant amount of continu-
ous power can generated as multiple cables can deployed
and Antenna size can also be increased thus increasing
onetime expense.
Few of the disadvantages stated:
• Onetime expense.
• For higher power generation, towers need to be in-
stalled.
• It’s not always predictable- windy days may be higher
eciency and sometimes it may have lower eciency.
Conclusion
In this review paper of Nikola tesla’s free electricity are
• Free Electricity circuitry can be designed based on the
Nikola Tesla’s patent For high voltages Zener Diodes
can be used provided circuit uses proper resistors and
capacitors.
• Using Nikolas Free Electricity one can generate elec-
tricity to charge an ordinary invertor battery contin-
uously.
• Signicant amount of power can be generated if it is
used at higher height like towers and multiple anten-
nae and cables can deployed, thus increasing ecien-
cy and continuous power generation.
• Higher level of continuous Electricity can be achieved
if height is higher (like Wardenclye Tower) assum-
ing broadness of antenna is also increased.
• If some of the Towers like Wardenclye are installed
then signicant amount of electricity can be generat-
