=_Reliability._=—The Light is
solely derived from Storage, and
is absolutely steady. There is no
connection whatever between the Lamp
and Moving Machinery.
The Supply is continuous day and night.
=_Economy in Prime Outlay._=—The
proportion of Engine Power in use to
the power required for maximum supply
is only about _one- third_, while any
system, if running direct, requires
a large portion of the plant to be
duplicated.
=_Economy in Working._=—The
generating station is only at work a
definite number of hours during the
daytime, after which period the plant
may be let out or utilized for other
purposes, such as motive power, &c.
=_Electro Motors_= for all
purposes can be driven from the
ordinary discharge mains. This is
impossible where alternating currents
are employed.
=GUARANTEE.=—The E.P.S. Co. undertake to supply
all the necessary renewals for the Storage
Batteries in use in the above system at the rate of
=12=% per annum on the actual first cost of
the Batteries.
E.P.S. Accumulators are already in use at the
following Central-Stations:—Vienna; Berlin;
Cadogan (London); Norwich; Taunton; Leamington;
St. Austell; Detroit, U.S.A.; Allentown, U.S.A.;
Blenheim, U.S.A.; Haverford, U.S.A.; Delaud, U.S.A.
