Dynamo

Dynamo[1]

A dynamo is an electrical generator that produces direct current with the use of a commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current alternator, and the rotary converter. Today, the simpler alternator dominates large scale power generation, for efficiency, reliability and cost reasons. A dynamo has the disadvantages of a mechanical commutator. Also, converting alternating to direct current using power rectification devices (vacuum tube or more recently solid state) is effective and usually economic.

On Earth-2A, a dynamo was used to power the magnetic telescope. The Metropolis Police Department sabotaged the machine.[2]

The Mole family stole a dynamo from the Power & Electric Company to power their stolen air conditioners in Molesville.[3]
