Water Wheel Design

Overshot and backshot wheels are the most efficient water wheel design; a backshot steel wheel can be more efficient (about 60%) than all but the most advanced and well-constructed turbines. The development of the hydraulic water wheel design with their improved efficiency (>67%) opens up an alternative path for the installation of waterwheels in existing mills, or redevelopment of abandoned ...

Windmill Efficiency.

A good guess at design efficiency can be made by direct observation. Only measurements under operating conditions can improve upon direct observation. For this reason, the US government spent a large amount of money (probably more than a billion dollars) during the late seventies and eighties creating experimental windmills for testing their practicality.

The Truth About Small Wind Turbines

A Darrieus type vertical axis wind turbine (the egg-beater type) can in theory work almost as good as a horizontal axis turbine. Actual measurement of one of the better designs out there, the UGE VisionAir5 , does not bear that out though: It measures in at a pitiful 11% efficiency at 11 m/s wind speed, while a Bergey Excel-6 HAWT clocks in at 22% efficiency for that same wind speed, twice as ...
