Vertical Axis Disk Wind Turbine

How the turbine works: Rotatable shutters mounted on a circular disk automatically open when directed into the wind, irregardless of the wind’s direction. Pairs of upper and lower shutters are geared together. The lower shutter acts as a counterweight to the upper shutter. The bottom shutter opens in the downward direction and its weight helps to lift the upper shutter in the upward direction, as the wind applies an opening force against both shutters. When the shutters reach the vertical position, stops prevent them from opening further and the force of the wind is transferred from the open shutters to the circular disk. And the circular disk is attached to the vertical axis for power output. The circular disk, shutters, and outer vertical axis rotate together. The outer vertical axis is mounted via bearings over an inner vertical axis that is stationery. The shutters are blown closed by the wind (no stops in the opposite direction) as they reverse direction during their rotation and move into the wind on the opposite side of the wind turbine. When the wind is not blowing, the shutters open by gravity because the lower shutter is weighted to be slightly heavier than the upper shutter and it therefore can cause the upper shutter to open via the force of gravity as the two shutters are geared together. Wind blows against the open shutters and the open shutters with stops apply a force against the disk, but the open shutters with no stops (opposite side going into the wind

Egin, Salisbury & Riverview Fire respond to a Wind Mill on fire at the Wind Mill Farm in Parkingdale/ Caledonia Mountain at 8:48am. There was nothing the Fire dept could do but watch it burn as they have nothing that goes up that high. This is about 30 kms outside of Riverview New Brunswick. Damage will be in the millions of dollars. Video aired on CTV , CBC & Global NEWS.

Complete Premium video at: fora.tv Habib Dagher, Structural Engineering Professor at the University of Maine, describes the concept of offshore wind turbines that float in deep water. Currently, the only fully operational floating wind turbine in the world is located in Norway and serves as a model for a planned offshore wind farm in Maine. Ironically, engineers borrowed the design from floating oil and gas rigs. —– Habib Dagher, the Bath Iron Works Professor of Structural Engineering at the University of Maine, is the founding director of the AEWC Advanced Structures and Composites Center. Established by the National Science Foundation in 1996, the interdisciplinary AEWC Center is a world leader in the development of cost-effective, high performance hybrid composite materials for construction applications. The center recently received million in funding from the Department of Energy for the development of offshore wind energy off Maine’s coast. – Chautauqua Institution Dr. Habib Dagher is Professor of Civil/Structural Engineering at the University of Maine, Bath Iron Works Professor of Structural Engineering, and founding Director of the AEWC Advanced Structures & Composites Center.

Wind power is one of the fastest growing forms of alternative energy in the world. More and more, wind power mills are seen in the countryside, in large wind farms and for the most part, away from city life. But a new form of wind power is now designed to work in an urban environment. VOA producer Zulima Palacio has the story. Mill Arcega narrates.
