wheels Of thousand industries spinning anywhere on
earth with its magnificent energy.
XIHILE the general public has not been taken into
w Tcsla's confidence concerning the progress OF his
work in he perfection Of his system for the wireless trans
mission Of power, scientific and electrical engineers in
all countries have followed closely and with intense IN
tcrc~ such developments AS he has revealed TO e teen
nioal world For obvious reasons however, 1t would
not bc prudent 20 disclose the actual working details OF
the system or the specific nature Of apparatus 10 be en-
rloycd until such time ne may elect TO place his
tr.insritcr on the market for commercial purposes.
There is says Tesla, much misunderstanding in
regard to my wireless system. Some believe that the
transmission effected through the air and others that
the currents 30 only through the earth. The fact IS

passes through the earth; but equivalent electrical
displacement also occurs in the air exactly when the
transmission is effected through single wire without
return: principle the practcabllty Of which demon
stratcd in my earlier investigations.
BY this system, he continues, "wlrccSS power can
be Transmitted with absolutely the same facility to the
antipodcs 1t can TO distance OF few blocks he
quantity Of energy the rdnsmtcr delivers lSlmmatcnal;
but in view OF the fact that the earth is immense, and
that there are practical limits in the amount of energy
collected in any individual receiver, It is necessary to
have a very powerful transmitting plant
"IIowcver,' he explains, "thc volume OF cncrgy-the
indicated horsepower Of the generating pant-wl not
in the least affect the limit Of transmission That is,
plant generating hundred horsepower will transmit
its energy to the same unlimited terrestrial distance as
that Of plant generating hundred thousand horse
power Neither will the energy or power decrease in
efficiency as the distance Of transmission increases, as
is the case with electrical energy transmitted by wire.
The efficiency OF Transmission viii be the same lrrcSpcc-
tive Of the distance or the amount.
"Whcn conveying power through wire Professor
Tesla points out a. certain loss is incurred due to the
resistance Of the conductor; but the earth is conduct
ing body OF such dimensions that there IS viz
tualv no loss 50 that distance nothing. TO the
average intelligence this will appear incomprchcnSblc
We are continuously confronted with limitations, and
those truths which con,radiccd by our senses
the hardest to grasp. For example, of the most
difficult tasks was TO satisfy the human mind that the
earth rotated round the sum- for to the eye it seemed
just the opposite

is made that places it at about onc-sxtcenth that of
the present means and sources Of supply. At any rate
Tesla SAYS that it will be far cheaper than any other
source known to man. With wireless energy, he con-
