Building the Elementa Aerogenerator
The generator itself weighs 4 kilograms
With yaw mechanism and propeller it weighs under 7 kilograms.
An estimated one and a half billion people worldwide, like our friends in the Andes of Chile, lack any source of electrical supply. A further one billion have only unreliable or intermittent power.
Electricity brings social progress by providing safe lighting, communication, entertainment and use of power tools. Such power can be delivered using small wind generators.
Our purpose was to design, prototype and test a small machine which was simple enough to be assembled locally on a “cottage industry” basis without need for advanced skills or equipment. This could give the following advantages:
Checking alignment of hand-

coils and stator
2. Labelling and weighing the coils of copper wire
3. Compressing the stator,showing the stator mould
4. Drilling the stator to take the drive shaft
5. Fitting and gluing the magnets to the magnet disc (rotor).
6. Assembling the magnets discs and bearing housing.
7. Measuring and cutting the propeller blades
8. Propeller and assembled generator
9. Generator and cable outlet
10. Attaching the generator to the cantilever mast
11. Store the electricity in a battery bank
12. Benefit from a safe lighting system
Electricity provides safe lighting and power for productive work
