ns that are able to concentrate
the largest amounts of money, representing the work of the dead, can have
the fullest use of the stored-up energies of time and the ancient sun.
Thus the monopoly of the stored-up energies of the sun arises from
monopolizing the accumulated fruits of dead men's toil. These problems
will, in the future, be the concern of the science and art of Human
Engineering.

Let us glance briefly at the problems from another angle. The power
developed in the combustion of one pound of coal is theoretically equal to
11,580,000 foot pounds. But by our imperfect methods of utilization, not
more than 1,500,000 foot pounds are made available. This is about the
amount of physical power exerted by a man of ordinary strength during a
day's work. Hence 300 pounds of coal will represent the labor of a man for
a year. The current production of coal in the world is about 500,000,000
tons (1906). If we suppose that only half of this coal goes for mechanical
use, this will give us approximately the number as 1,600,000,000
man-powers that are producers but not consumers.

Let us take a still broader view of resources; we have approximately
1,600,000,000 living human beings (all censuses available between 1902 and
1906); a wealth of approximately $357,000,000,000 (_Social Progress_,
1906, page 221) which in our analysis is dead men's work; and sun-power
equal, in work, to the work of our whole living population, or equal to
1,600,000,000 sun man-powers. Taking, for simplicity's sake, $35.70 as the
average living expenses per annum for each one of the _world's_
population, we will have:

(1) 1,600,000,000 living men.

(2) 10,000,000,000 living man-powers of the dead.

(3) 1,600,000,000 sun man-powers.

Such classification needs a reflection: man is intrinsically an increasing
exponential power and always produces two use-values--the potential and the
kinetic. All living men have in some degree this type of power; _they are
able to direct and use basic powers_.

So we see that this world is really populated to-day by three different
populations, all of them dynamic and active: to wit, 1,600,000,000 living
men; 10,000,000,000 living man-powers of the dead; 1,600,000,000 sun
man-powers.

Thus it is obvious beyond any argument, _that this additional producing
but not consuming_ population, has been produced mainly by the work of all
our past generations. It is said "mainly" because, if we were the first
generati
