Lamp Once Charged viii
Keep Going; No Current
Needed, Says Inventor

"lre4ess Nght-thc long -aought-for
cold light, so-caled-will be the next
great development Of the wireless era,
If the plans of the TomadelH Corpo-
ration, 10 Journae Square. Jersey City,
are brought to maturity.
Bottled sunlight" is the way the
company characterizea it's product, de-
claring that the lights it manufactures
Will burn continuously for three wears
without any further application of
electric current beyond that which ell
ergizcs them and sets them glowing
in the Tomadelli laboratory before
they are shipped out to their pur-
chascrs.
Close secrecy has marked operations
Of the corporation so far, and it was
cnly yesterday that The officials Of the
concern, partial account Of their ac-
tlvltlo8 having come out Sunday, were
willing to disclose to a Tribune re-
porter the first complete story of their
plans. Not only has the Office force in
Jersey City hitherto made strenuous
attempts TO hush the matter up, but
the corporations red brick laboratory
IN Bergen, n. j., has been made place
OF mystery to its neigh bors by its utter
inaccesslblllty during the daytime and
by the presence of tho two armed
gl ards who patrol it at night. The
profoundest silence has been enjoincd
on the small group Of stockholders who
ere supplying the capital for the pre-
Amlnary work that Will result, it is
said, IN public demonstration of one
OF the automatic electric shcdders Of

SelfSustaining Incandcsccnt
a concise and non-tecIlnical descrip.
ton of the lamp for which such revo-
lutlonary possibilities are asserted
would be, according to one Of the cor
poTation's founders, that "it is a self
sustaining incandescent electric LIGHT
that Will burn for long period of time
Wlthout connection to any source OF
electric power other than itself, The
ityontion Of which it is s. part includes
: dynamic apparatus for charging the
lamps by atmospheric induction at the
factory so that they can be shipped
out and guaranteed to remain lighted
continuously for any desired period un
to several years"
Attached TO each lamp, it is said, will
be metallic device similar to the
petals OF flower, which may be opened
92uC or contracted at will as light Or
darkness is desired, since, once started,
the lamp cannot be eXtinguishel.
Another remarkable feature Of the
Tomadelli light, it is declared, is that
Is produces light without any waste Of
energy III generating heat, or, in other
words. that it clnbodios the "cold
light for whose discovery electrical
engineers and scientists have spent
great sums in experimentation. The
temperature of the "wireless Light is
said TO remain at about 10 degrees
above freezing point on the Fahrenheit
scale. as compared with p heat OF 100
degrees or more generated by Q high
voltage incandescent bulb Of the or
dlnary type.
Disc0Yerer an Italian
Juan J. Tomadelli, Italian civil and
clectro-m echanical engineer, is credited
with the discovery that makes the
self sustaining lamp possible. He is
forty-four years old and was educated
ct the University of Zurich, the Uni
versity Of Turin and the Polytechnic
Of Vienna. In the latter he was for
two years assistant to DR.. II. Albert
Scherman, professor Of electrical
science in that institution, with whom
he Is declared to have done extensive
electrical research work. Tomadelli
then spent number OF years assist
ing in the compilation Of technical
encyclopedia, and later he was called
to the Argentine Republic 10 take
charge of large electrical construc-
ton program. He became chief enei-
neer OF public works there. and for
about three years was occupied in the
installation Of power plants and cleo
tric railways.
While in the Argentine it is said f!
Mr.. Tomadelli developed his long
cherished plans for practical work !
ing apparatus for producing wireless
light. He resigned from his position |
and spent four and half years per-
fecting his invention. He succeeded |
in charging number Of lamps, and
it is said that one of them, of which |
are shown by the cor
Oortation, had burned continuously for !
more than seven months when the !
Tomadelli house and laboratory were
struck by lightning and destroyed and
the inventor badly shocked on July
Is, 1919. A short time before this
occurred Mr.. Tomadelli had given g.
private demonstration Of his lamps to
q small group OF friends and electri- |
cal experts, and after he recovered /
