Oct 31, 2014· When wind blows on a verticalaxis turbine, only a fraction of the blades generate torque while the other parts merely 'go along for the ride'. The result is comparably reduced efficiency in power generation. Simply put, because power generation efficiency isn't as good, VAWTs aren't as good longterm investments.
Oct 16, 2009· "The more parts, the more that can go wrong," says Vertical Wind CEO Björn Hellström. "We make it as simple as possible. Only a single unit needs to move." Research in several fields. Vertical Wind is an outgrowth of the Division for Electricity at Uppsala University, where wind power research has been conducted since 2001.
windmill and it must be properly sized to match your swept area and to produce right type of power to match your application. The unit needs to make higher voltages at lower rpms, otherwise it is not suited for wind power use, even motors can also be used a generators. In this vertical axis highway windmill we are using two dc

These windmills were mainly used to pump water or to grind wheat. They had vertical axis and used the drag component of wind power: this is one of the reason for their low efficiency. Moreover, to work properly, the part rotating in opposite direction compared to the wind had to be protected by a wall.
