- If it lost power in distribution, it was because the machines were not designed
- to use minimal power when idle. Mechanical power distribution (chains,
- belts, and gears) is very efficient, 95% or greater. So it was machine
- design, not distribution that was a problem. The real problem with
- mechanical distribution is that a single fault brings all work in the factory
- to a halt. Individual motors increases productivity by reducing downtime.

- Statistics from the industrial revolution on show this relationship is
- true throughout great advances in technology and large changes in economics
- and politics. Undoubtedly, factors such as technological and efficiency
- improvements are included in the relation but turn out to be offset by
- other factors such as population growth, standard of living increases, etc.
- To fully analyze the relation would require analyzing all these components,
- but the relation itself stands and is as true today as it was a century ago.
