Abstract
In the effort to develop a cheap power source for developing areas we have designed and constructed a 32-ft (9·75 m) diameter airscrew windmill. The airscrew designed by ourselves, incorporates the most recent aerodynamic theory. It comprises three blades manufactured under contract by a Canadian firm in fibre-glass reinforced epoxy resin. The manufacturing method is reasonably inexpensive and gives scope for local production in the developing countries at a later date. The shaft drive down the tower incorporates standard automobile and truck transmission components, which are available cheaply in many countries.Keywords
