A debate over whether it is best to harness wind energy with horizontal-axis devices or vertical-axis devices has raged for thousands of years. Even how the technologies evolved is under some dispute.

Wind Engineering, Vol. 13, No. 6 (1989), pp. 315-323 (9 pages) This paper describes a modelling system designed to investigate the effects on the cost of energy production of variations in selected ...

Compact (H-type) vertical-axis wind turbines (VAWTs) are not as familiar as their horizontal-axis, propeller-type cousins. The two have their origins in the windmills of the 12th century, and even ...

Since childhood, Michael Carruth, a junior in the environmental design program at CU-Boulder, has been fascinated with nature. Long hours spent playing outdoors, observing swirling leaves, clouds ...

Wind energy researchers are re-evaluating vertical axis wind turbines (VAWTs) to help solve some of the problems of generating energy from offshore breezes. Sandia National Laboratories' wind energy ...

When most people think of wind power they think of large-scale wind farms with fields of huge three-bladed horizontal axis turbines. With such farms requiring lots of room they are generally ...

The now-familiar sight of traditional propeller wind turbines could be replaced in the future with wind farms containing more compact and efficient vertical turbines. New research from Oxford Brookes ...
