These machines are made from recycled Fisher and Pykle washing machine motors and other bits of recycled equipment and materials. There are two types of wind turbines here - propeller and verticle axis using a plastic 200 litre drum cut in half. They are usable by children from about 15 years old up to adults.
Adult supervision is required.
They are capable of powering light globes - incandesent, compact fluoroescent intermittantly by spinning them by hand or continuously in a strong wind.
