BIG POSSIBILITIES
IN new RADIO TUBE
Gives Rise to Fantastic
Sounding Claims of Wireless
Power Transmission.

Visions of the day when homes viii
b. heated and lighted without wires tc
carry the electrical current and when
automobiles and airplaneS will be driven
By energy drawn from the ether are
suggested by the demonstrations OF
General Electric Co. engineers with
wave radio tube.
MANY predictions have been made re-
gardillg the possibility of transmitting
uscacle energy by radio, many Of them
rash. most of them arouSing SkepticiSmi
in the minds Of competent scientists.
Visionary in, the extreme. some of the
predictions represent dreams which
some persons believe will become reality
in time.
Who wiz gainsay anything in this
age OF wonders
New Wonder Tube.
The General Electric tube. standing
two feet in height and five inches in
diameter, lishted incandescent lamps to
fun krilnancy without wires OK socket,
cooked a sausage, fried an esq and
baked an apple attached to an aerial
picking up its high frequency emana-
tons. and radiated heat enough to have
O death-dealing effect upon rats and q
blood-warming effect upon humans.
The ''hroadcaSting" Is on wave
length of six meters. far down in the
part of the radio wave spectrum that is
generally regarded as radios purgatory.
The self-excited oscillator is capable of
radiating up 10 $4,000 watts Of power
into space, which is about so times as
much as any short-wave tube has ever
been able 10 produce.
The experiment recalls the oft-re-
pca.ed assertions OF Nikola Tesla, the
aged New York inventor. to the effect
that wireless power transmission will
one day rcvolutioniEe the whole electro
cal industry. All the power now dissi-
pated III being radiated into space
not even the strength Of fly is repre-
scntcd in the energy by which an ordi-
nary receiving set picks up program
will be saved and used. Mr.. Tesla main
tainS. He ventures the assurance that
automobiles will draw their motive en-
ergy from central power ''broadcasting"
stations: that incandcscent lamps will
be supplanted by electrodeless vacuum
or gss-fiilled tubes which it will not be
necessary TO connect by wires
Static Energy Motor.
c. Francis Jenkins. Washington in
ventor. has perfected a tiny motor
which he claims is run entirely by static
energy. II is held between thumb ond
fingers ana is connected with an an
teI1na and ground wire. The static en-
energy is received By the antenna and
passes into the miniature motor. actu-
attng it.
Several demonstrations were offered
IN Washington recently OF the control
OF automobiles and a street car by radio.
These, of course. did not represent
transmissiors of energy. but merely
wireless control of actuating devices,
The Army and Navy have controlled
tank and ship movements by radio.
John Hays Hammond. jr.. the radio in
veator, several weeks ago obtained
patent on a system of radio control OF
engine speeds adaptable TO motor cars
OF locomotives. He WAS the inventor OF
the torpedo direction control by radio.
