Short Description and Uses

This small wind turbine is a machine in which the working parts are a set of powerful Neodymium alloy magnets and a series of copper coils. Powered by a wind-driven propeller it generates an electrical current suitable for charging 12-volt batteries such as a car batteries. From these you can run a number of useful electrical appliances such as lights, radio, black and white TV, small computer, phone charger, and water pump. All these are commonly and cheaply available as 12-volt items. You can also convert the low voltage direct current (DC) from the battery into mains alternating current (AC) from which you can operate power tools such as electric drill, angle grinder or fret saw.

We will show you how the machine can be made from readily-available materials and components with little previous knowledge or skill.

Newcastle upon Tyne University “Engineers without Borders” group assembling the wind turbine.

Weight of the machine:

Generator alone, 4 kg. With yaw mechanism & propeller, 6.75 kilograms. Propeller diameter , 1.2 metres.

Low weight and small size means that one person alone can assemble and erect the machine

Why would you be interested?

Where there is no connection to cheap mains electricity, a renewable energy device,such as this small wind turbine will give you sufficient electricity to power a number of devices essential to modern living.
