Did You Know?
The dynamo was introduced in 1832 to produce electricity for commercial use. Like all later generators, the original dynamos changed mechanical energy (produced by steam, which was itself produced by burning coal) into electricity. The word is less used today than it once was, since it's often applied only to generators that produced direct electric current (DC) rather than alternating current (AC), which is now the standard. A human dynamo is a person who seems to have unlimited energy, such as New York's legendary mayor Fiorello La Guardia, whose forcefulness and vigor matched that of his intensely dynamic city.
