Regarding power distribution frequencies, in addition to 50 and 60 Hz, 400
Hz is used by the military in some shipboard systems and in aircraft. RF
power distribution systems in the 20-40 kHz region have also been suggested.
I believe that NASA has explored this.
On a related topic, is anyone aware of any statistical studies having been
done on the physiological and neurological effects of long-term exposure to
the electric and magnetic field energy associated with Tesla coils?.
Also, not all Tesla coils have a primary capacitor and some sort of a switch
to discharge it at lengthy intervals relative to the fundamental resonant
frequency. Tesla used "another kind of circuit" that was used to produce
"perfectly undamped waves."
I used the apparatus, yes, in connection with the antenna too, but . .
. I used it in every connection. . . . the apparatus was used in all my
work, in all my investigations. . . . I had different kinds of apparatus.
[In Manhattan] I had a sensibly damped wave because at that time I still was
laboring under the same difficulties as some do this day -- I had not
learned how to produce a circuit which would give me, with very few
fundamental impulses, a perfectly continuous wave. That came with the
perfection of the devices. When I came to my experiments in Colorado, I
could take my apparatus like that and get a continuous or undamped wave,
almost without exception, between individual discharges.
Speaking of your not having perfectly undamped waves at that time, you
were referring to that character of circuit?
Yes, but with another kind of circuit I could, of course.
The advantage of this apparatus was the delivering of energy at short
intervals whereby one could increase activity, and with this scheme I was
able to perform all of those wonderful experiments which have been reprinted
from time to time in the technical papers. I would take energy out of a
circuit at rates of hundreds or thousands of horsepower. In Colorado, I
reached 18 million horsepower activities, but that was always by this
device: Energy stored in the condenser and discharged in an inconceivably
small interval of time. You could not produce that activity with an
The damped wave is of advantage because it gives you, with a generator
of 1 kilowatt, an activity of 2,000, 3,000, 4,000, or 5,000 kilowatts;
whereas, if you have a continuous or undamped wave, 1 kilowatt gives you
only wave energy at the rate of 1 kilowatt and nothing more. That is the
reason why the system with a quenched gap has become popular.
I have refined this so that I have been able to take energy out of
engines by drawing on their momentum. For instance, if the engine is of 200
horsepower, I take the energy out for a minute interval of time, at a rate
of 5,000 or 6,000 horsepower, then I store [it] in a condenser and discharge
the same at the rate of several millions of horsepower. That is how these
wonderful effects are produced. The condenser is the most wonderful
instrument, as I have stated in my writings, because it enables us to attain
greater activities than are practical with explosives. There is no limit to
the energy which you can develop with a condenser. There is a limit to the
energy which you can develop with an explosive.
