The Darrieuswind turbine is a type of vertical axis wind turbine (VAWT) used to generate electricity from the energy carried in the wind. The turbine consists of a number of aerofoils vertically mounted on a rotating shaft or framework. This design of wind turbine was patented by Georges Jean Marie Darrieus, a French aeronautical engineer in 1931.
Much of the swept area of a Savonius rotor is near the ground, making the overall energy extraction less effective due to lower wind speed at lower heights. Savonius turbines are used whenever cost or reliability is much more important than efficiency. For example, most anemometers are Savonius turbines, because efficiency is completely irrelevant for that application. Much larger Savonius turbines have been used to generate electric power on deep-water buoys, which need small amounts of power and...
Designed for people who operate and maintain their own system. Dragonfly philosophy recognizes that nothing manmad lasts forever, but planned obsolescence is unethical. So the Dragonfly is designed to last as long as the user has interest. It has locally available spare parts, few critical tolerances, and the maintenance technology is uncomplicated. Components are adaptable to the supply: off the shelf hardware, lumber, and almost any make of alternator or generator. Included with plans are directions...
This small, easy to build, engine/alternator is the answer to a burning renewable energy question. What do we do when the sun doesn’t shine, the wind doesn’t blow, and the water dries up? This generator is a backup power source for times when our renewable energy sources don’t meet our demands. It is optimised to do only one thing — properly recharge batteries on demand.
