How does Hand Crank Power Work?

At times, the appearance of a device powered by a hand crank can seem archaic and may
conjure up images of an old butter churner or Model-T crank start car, but the technology behind hand crank powered objects is anything but old fashioned.  While the design, concept, and science behind how a hand crank powered object works is relatively simple, and yes even relatively old in advent, the modern applications of hand crank power can be as advanced as they are helpful.

The basics of a hand crank include generating electric power through the kinetic motion of a crank and the use of wires and magnets.  In 1831 a scientist name Michael Faraday discovered that he could generate a consistent supply of electricity by spinning a coil of conductive wire around a magnet, or by passing a magnet through a cylinder of conductive wires.

Through this initial discovery of the early eighteen hundreds has led to the modern applications of hand crank power—which effectively turns the power of a person’s arm into the initial power needed to create electricity thorough the application of wires and magnets as discovered by Faraday.

Today, hand crank powered objects provide people with indispensable emergency supplies of electricity to power important survival gear.  The ability to power by one’s own hand such emergency needs as a flashlight or radio have allowed individuals to prepare for a power loss or emergency situation with the security that they will be able to power their supplies and equipment even if batteries fail or electricity is lost.  Some of the most popular hand crank products provided by 21 Century Goods include:
