Save Time, Money, and Energy

What process would benefit from saving time, money, or energy?

In the 1800s, steam trains had to shut down their massive engines for the moving parts to be oiled. African Canadian engineer Elijah McCoy realized that shutting down the engines was a waste of time, money, and energy.

In 1872, he invented a device called the oil lubricator, which automatically delivered oil to the moving parts of an engine. Other railroad workers liked the idea and began using it. The device also caught the attention of machinists, who requested that McCoy build oil lubricators for their needs as well.
