An array of Batteries connected in series, parallel, or both.

A material that shows magnetic properties only while exposed to an external magnetic field.

See Alternating Current

The cross section profile of the leeward side of a wind generator blade. Designed to give low drag and good lift. Also found on an airplane wing.

In a permanent magnet alternator, the distance between the magnets and the laminates.

Electricity that changes direction periodically. The period is measured in Cycles per Second (Hertz, Hz).

A device that produces Alternating Current from the rotation of a shaft.

A unit of electrical current, equal to Coulombs per second. This is the flow rate of electrons moving through a circuit, very roughly analogous to gallons per minute flowing from a faucet.

A measure of energy quantity, equal to amperes times hours. Also used to measure battery capacity.

A device that measures wind speed.
