IN THE BASEMENT oi the Roxy, the above compact. illuminating gas powared motor generator started

to carry the full current load within five seconds.

Gwilym A. Price, President of Westinghouse Electric Corporation, described the growth of the electric power load in the years ahead: ttThe annual load on power systems in this country will grow at the rate of 30,000 k.w. hrs. per minute for each of the five and a quarter million minutes that comprise the next ten years. This is the gist of the predictions that have resulted from a power-load survey for the coming decade made by Westinghouse. Furthermore, to meet this rising load will require an increase of 80 per cent in the nations installed generating capacity. With concomitant increases in other facilities, electric utilities will be required to match in ten years all their investment to date. The estimates are based, insofar as possible, on fact; they are not mere extensions of curves of past

performance. However, large as these

charted increases are, there are good reasons for thinking that these prognostications are on the conservative side. This is because of numerous intangible but inexorable trends that are diiiicult to reduce to concrete figures."

Power Shortages

The Federal Power Commission reported in November, 1947, that the nation is burning electricity at the greatest rate in historye17 per cent above the war-time peak! And in the winter months of 1948, California stayed on daylight saving time to conserve power. Even this does not tell the entire story; this power shortage which is being, felt in many areas and has already given theatre owners trouble, is only part of the problem. Several disastrous fires in public places in recent years have focussed attention on the necessity for re THE RELATIVELY SIMPLE CONTROL BOARD in the Roxy shows the line transfer equipment for the emergency power adjacent to the normal power controls.

liable emergency service, in case of power failure.

Violent weather threatens to increase the difficulty, if the record of past months is any indication. From the Canadian border to the Gulf of Mexico, storms, hoods, sleet and unforeseen disasters of every kind may boost the "normal" rate of power breakdowns to record proportions. Unfortunately, too, this precarious condition is susceptible to aggravation at any time by coal and other fuel strikes which inevitably produce ordinances severely restricting the use of dwindling current supply by theatres and other places of public assembly. Despite the efforts of commercial power companies to keep the lines open, thousands of power failures are likely to occur in a years time.

Blackouts are Preventable

In a business which depends so much on electricity, power failures usually have a paralyzing effect. But today it is no longer necessary for an operator of a movie house to "sweat it out" when the projector sputters to a stop, the screen goes black and the lights go out because the power is dead.

The theatre operator in the average size town may try to convince himself that hes not going to be seriously affected by such power failures. But, in reality his troubles are very likely to parallel those of the Roxyis, where standby power saved the show many times, Therefore, in a business whose very lifeblood is electricity, it is essential that the smart operator be conversant with equipment which will guarantee uninterrupted supply of electrical power whenever lino breakdowns jeopardize the usual source of electricity.

Available Equipment

There are two principle types of emergency generating equipment for practical theatre usage: a storage battery system, when adequate lighting for auditorium and exits is the primary consideration; or, either gasoline illuminatng gas or diesel-driven equipment, when a power plant with sufficient capacity to provide lighting and also keep the show going, is desired. Storage batteries with a capacity for l'/z hours'
