THE CONSERVATION OF OUR ENERGY RESOURCES 303

derive by elemental fission cheap, universally obtainable power in unlimited

quantities. Our oil and coal resources must otherwise be exhausted within a

few centuries. These must be conserved for more essential services than mere

power supply.

In 1940 the Rockefeller Foundation demonstrated its faith in the

possibilities of atomic power by giving $1,150,000 toward a new

4900-ton cyclotron to be erected at

Berkeley, California.

Wind power has been used in

windmills and is now being used

on farms to run generators which

charge batteries and thus provide

a fairly constant source of power.

Large-scale harnessing of the wind,

however, depends upon storing the

wind's energy. So far, all storage

devices have been too expensive to

be economically feasible.

National Planning Has Been Made

Necessary by Science and Is

Dependent upon Science.

Where the ancients knew only soil,

forest, wild animals, and a few simple

metals, we know thousands of natural

and artificial substances that we turn

to our purposes. Where they worked

slowly with arrow, axe, and plow, we

operate with tractor and steam shovel,

with poison and fire, with gold-dredge

and dynamite. The low-powered civilizations

of the past, rattling around

in an almost uninhabited wilderness,

could get along with low-powered

plans. If their resources failed, they

wind areas it will generate sufficient

electricity to light the home, run the

machines, irons, and refrigerators.

could move to new land. It is not so

easy now. We depend for our lives on a vast, intricate network of technological

processes, carried out in mine, farm, and factory. We cannot easily

pack everything on a mule and trek. Therefore we have to manage what we

have, finding ways to control the process of social change, or at least to see

it coming and get out from under the wheels.

The simple political and industrial planning of the first years of the Republic,

when Alexander Hamilton introduced the protective tariff, will not suffice to

meet modern problems. At the present time the country is obliged to make

decisions as to great systems of public works, as to elaborate public health

services, as to the powers and relationships of corporations, and as to the
