Follow the thread back, he suggested power stations in space.
If power can be sent without wires, it would be used on Earth first, has
it?
This will probably be the first Earth-bound application:

10 KW over 700 meters? The paper is ten years old,
if it hasn't happened, maybe it won't.
A few years short, maybe 100

THE WIRELESS TRANSMISSION OF ELECTRICAL ENERGY
by Gary L. Peterson
It is possible that Nikola Tesla is best known for his remarkable
statements regarding the wireless transmission of electrical power.
His first efforts towards this end started in 1891 and were intended
to simply "disturb the electrical equilibrium in the nearby portions
of the earth... to bring into operation in any way some instrument."
In other words the object of his experiments was simply to produce
effects locally and detect them at a distance. By 1899 the electrical
potential of his transmitter had increased to the point that more room
was needed for the sake of safety. This and other considerations led
him to temporarily shift his wireless experiments to a location just
outside of Colorado Springs.
At this Colorado "Experimental Station" Tesla had some early success
in wireless power transmission. One photograph shows that "a small
incandescent lamp was lighted by means of a resonant circuit grounded
on one end, all the energy being drawn through the earth [from a
nearby transmitter]." In 1907 he even went as far as to make this
statement:
"... to make the little filament glow, the entire surface of the
planet, two hundred million square miles, must be strongly
electrified. This calls for peculiar electrical activities, hundreds
of times greater than those involved in the lighting of an arc lamp
through the human body [a far more spectacular demonstration]. What
impresses him most, however, is the knowledge that the little lamp
will spring into the same brilliancy anywhere on the globe, there
being no appreciable diminution of the effect with the increase of
distance from the transmitter."
It is not at all clear that Tesla was referring to effects produced by
his large Colorado transmitter. It is quite possible that he was
writing about what he felt could be done with an even bigger
transmitter such as the one that he was developing in New York. If the
Wardenclyffe communications facility had been finished, the 187 foot
tall mushroom-shaped tower would have permanently housed a set of
large coils including an immense helical resonator that would have
served as the main transmitting element. Directly below the wooden
tower there was a 120 foot shaft where deep underground Tesla had
installed a radial array of iron pipes that served as a connection
between the oscillator and the earth.
The Wardenclyffe plant was a major milestone in Tesla's researches
into the application of alternating electrical currents to wireless
communications and power transmission, an effort which drew a
considerable amount of Tesla's attention during the period between
1891 and 1912. In the article "The Future of the Wireless Art" which
appeared in Wireless Telegraphy & Telephony, 1908, Tesla made the
following statement regarding the Wardenclyffe project on which he was
then working:
"As soon as completed, it will be possible for a business man in
New York to dictate instructions, and have them instantly appear in
type at his office in London or elsewhere. He will be able to call up,
from his desk, and talk to any telephone subscriber on the globe,
without any change whatever in the existing equipment. An inexpensive
instrument, not bigger than a watch, will enable its bearer to hear
anywhere, on sea or land, music or song, the speech of a political
leader, the address of an eminent man of science, or the sermon of an
eloquent clergyman, delivered in some other place, however distant. In
the same manner any picture, character, drawing, or print can be
transferred from one to another place. Millions of such instruments
can be operated from but one plant of this kind. More important than
this, however, will be the transmission of power, without wires, which
will be shown on a scale large enough to carry conviction. These few
indications will be sufficient to show that the wireless art offers
greater possibilities than any invention or discovery heretofore made,
and if the conditions are favorable, we can expect with certitude that
in the next few years wonders will be wrought by its application."
In the end, Tesla was never able to complete the Wardenclyffe plant,
although he was able to conduct some performance tests. Nevertheless,
if the above stated predictions were to be true, an interesting
feature of Tesla's World System for global communications, had it gone
into full operation, would have been its capacity to provide small but
usable quantities of electrical power at the location of the receiving
circuits. He predicted that further advances would have permitted the
wireless transmission of industrial amounts of electrical energy with
minimal losses to any point on the earth's surface. Had he been able
to complete the prototype station on Long Island and use it to
demonstrate the feasibility of wireless power transmission then a plan
would have been implemented for the construction of a pilot plant for
this larger system at Niagara Falls, site of the world's first
commercial three phase AC power plant.
