This video explains why a regular AC motor cannot be used AS IS to act as an electrical power generator.
The ceiling fan motors have the stator in the center and the outer portion that usually attaches to the fan blades rotates around the stationary stator. This allows for Neodymium Magnets
A to be placed around the perimeter. When the outer portion spins, it produces an alternating current not usable by your house appliances.
A diode bridge is an arrangement of four (or more) diodes in a bridge configuration that provides the same polarity of output for either polarity of input. When used in its most common application, for conversion of an alternating current (AC) input into direct current a (DC) output, it is known as a bridge rectifier.
The combination of this arrangement makes a rather efficient generator at a very low cost per watt.
