How Powering with Atmospheric Electricity Works

Hi Gang!
I'd previously demonstrated generating power using atmospheric electricity.
A hexacopter was used to lift one end of a wire
high up into the air. Meanwhile the other end of the wire
was connected to a corona motor near the ground. Electricity then flowed through that wire
and corona motor, making it turn.
In this video I'm going to explain how it works. Much of the following explanation is adapted
from Nobel prize winning phsycist Richard Feynman's Lecture on Physics, his section called "Electricity in the Atmosphere". For every meter you go up in the air,
the voltage increases by around 100 volts, or we could say around 100 volts per yard.
We can draw these voltage increases using what are called equipotential lines.
Notice that the ground is negative and the sky is positive with respect to each
other. According to Feynman this extends upward to
50 kilometers, or 31 miles,
where the air is very conductive. This is the case in fair weather.
In stormy weather like a thunder storm things are quite different
and I won't talk about that here.

But if this voltage exists between your head
to the ground, why don't you get a shock?
The reason is that your body is a good enough electrical conductor
that standing on the ground you're basically a part of the ground.
The equipotential lines would look like this. There's still effectively 0 volts
between the top of your head and ground. Similar effects happen with trees, buildings
and so on.

What about the electric current?
A downward electrical current exists and consists of positive ions,
molecules or clumps of matter that have a positive charge.
These ions are moving slowly toward the ground. The current density from these ions is very
small, around 10 micromicroamps
or 10 picoamps crossing each square meter,
or yard, every second.
So in any small area, there's not a lot of power. And that's the explanation about atmospheric
electricity adapted from Feynman's Lectures. To take advantage of this atmospheric electricity,
we electrically connect one end of a wire to the ground,
and lift the other end up into the air. In our case we got good results at around
120 meters, or 390 feet up.
At 100 volts per meter, or 100 volts per yard,
that's 12,000 volts between that height and the ground.
But, just as with you standing on the ground, the wire is an electrical conductor
and so is also at ground potential.

Looking at the the equipotential lines around
the wire, that voltage of 12,000 volts exists
between some distance away from the wire, and the wire. You can see that the equipotential lines are
closest together at the top of the wire.
This means the attraction is strongest there, and electrons make their way upward in the
wire. Let's look more closely at the top of the
wire. We'd put six sharp points using sewing pins
at the top of that wire. But for ease of illustration I'll draw just
one. Notice that because of the sharp shape of
the point, the charges are crowded together at the point.
Remember also that there are positively charged ions in the air.
An electric field exists between the negative charges on the wire
and the positive charges in the air and we can represent that electric field by
drawing lines between pairs of opposite charges. Notice that the electric field lines
are closer together near the point, meaning the electric field is stronger there.
It's strong enough to remove the negative electrons
from the sharp point where they neutralize positive ions.
But, due to the voltage there are fresh positive ions
moving downward and fresh negative charges coming up from
the wire.

We now have electricity flowing through the
wire. The electric current in that electricity is
very weak though. We didn't measure it but from my experience
with electrostatics I'd estimate it in the low microamps
or more likely even lower. That's not enough to turn an electromagnetic
motor, one like you use in everyday life.
But it is enough to turn an electrostatic motor, like this corona motor. The corona motor consists of a plastic cylinder
surrounded by sharp edged metal blades. Every second one of those blades
is connected to the wire going up into the sky. That means what when the wire starts conducting, those blades are now at whatever voltage
the top of the wire is at up in the sky, though opposite in polarity, positive.
That's why you get a shock when you touch one of those wires. Negative charge is then pulled from the plastic
cylinder through a gap between the edge of the blade
and the cyinder. That leaves the cylinder with the same charge,
and since like charges repel, a repulsion occurs that rotates the cylinder.
The next blade is connected to Earth ground and becomes negatively charged.
And since opposite charges attract, it attracts the charged area of the cylinder.
It then neutralizes that charged area by taking electrons from the ground.

And that's how atmospheric electricity
can power an electrostatic motor like a corona motor. Well, thanks for watching! See my youtube channel for more interesting
videos like this. That includes one with a more detailed demonstration
of this atmospheric electricity in action powering
the corona motor. Another showing how this corona motor was
made. And one showing how to generate electricity
using a Peltier module. And don't forget to subscribe if you like
