Bladeless Wind Turbine for wind energy without blades

Wind turbines are a large and growing source of energy but the turning blades have led to concerns about sound and impacts on bird populations. People have also complained that such wind turbines are an eye-sore. A new structure designed by Dutch architecture firm Mecanoo and installed at the Delft University of Technology convert the wind to energy without any moving parts. They are often called as Bladeless Wind Turbine. The new technological innovation was developed by the Electrical Engineering, Mathematics and Computer Science faculty at Delft. It uses the movement of electrically charged water droplets to generate power.One can easily say, Bladeless Wind Turbine is an amazing thing that can produce wind energy without blades.

“Bladeless Wind Turbine for wind energy without blades” overview.

The prototype of the EWICON (Electrostatic Wind Energy Converter) is not impacted by traditional wear and tear that limit the life of traditional blade based turbines. As such it requires very little maintenance. Further, it makes no noise and casts no shadows. The new bladeless wind turbine technology has already been incorporated into the design of a project in Rotterdam.

 
 
Noise from wind turbine blades, inadvertent bat and bird kills and even the way wind turbines look have made installing them anything but a breeze. New York design firm Atelier DNA has an alternative concept that ditches blades in favor of stalks. Resembling thin cattails, the Windstalks generate electricity when the wind sets them waving. The designers came up with the idea for the planned city Masdar, a 2.3-square-mile, automobile-free area being built outside of Abu Dhabi. Atelier DNA’s “Wind stalk”project came in second in the Land Art Generator competition a contest sponsored by Madsar to identify the best work of art that generates renewable energy from a pool of international submissions.

The proposed design calls for 1,203 ““stalks,” of Bladeless wind turbine each 180-feet high. These values include concrete bases that are between about 33- and 66-feet wide. The carbon-fiber stalks, reinforced with resin. They are about a foot wide at the base tapering to about 2 inches at the top. Each stalk will contain alternating layers of electrodes and ceramic discs. Which are made from piezoelectric material. That can generate a current when put under pressure. In the case of the stalks, the discs will compress as they sway in the wind, creating a charge. 
“The idea came from trying to find kinetic models in nature that could be tapped to produce energy,” explained Atelier DNA founding partner Dario Nunez-Ameni.

In the proposal for Masdar, the Windstalk wind farm spans 280,000 square feet. Based on rough estimates, said Nunez-Ameni the output would be comparable to that of a conventional wind farm. Provided that are covering the same area. Added that “Our system is very efficient in that there is no friction loss associated with more mechanical systems such as conventional wind turbines,”

Each base of Bladeless Wind Turbine is slightly different. It is sloped so that rain will funnel into the areas between the concrete to help plants grow wild. These bases form a sort of public park space and serve a technological purpose. Each one contains a torque generator that converts the kinetic energy from the stalk into energy using shock absorber cylinders. It is similar to the kind being developed by Cambridge, Massachusetts-based Levant Power. The Wind isn’t constant, though, so Nunez-Ameni says two large chambers below the whole site will work like a battery to store energy. The idea is based on existing hydroelectric pumped storage systems. Water in the upper chamber will flow through turbines to the lower chamber. It will be releasing stored energy until the wind starts up again.

The top of each tall stalk has an LED lamp that glows when the wind is blowing. It goes more intensely during strong winds and not all when the air is still. The firm anticipates that the stalks will behave naturally, vibrating and fluttering in the air. Nunez-Ameni – “Windstalk is completely silent. The image associated with them is something we’re already used to seeing in a field. The hope is that people living close to them will like to walk through the field. Moreover, especially at night under their own, a private sky of swarming stars,” said Nunez-Ameni.

Expectations from “Bladeless Wind Turbine for wind energy without blades”

After completion, a Windstalk should be able to produce as much electricity as a single wind turbine. The extra advantage that output could be increased with a denser array of stalks. Density is not possible with conventional turbines. They need to be spaced about three times the rotor’s diameter in order to avoid air turbulence. But Windstalks work on chaos and turbulence so they can be installed much closer together, said Nunez-Ameni.

Nunez-Ameni also reports that the firm is currently working on taking the Windstalk idea underwater. Called Waves-talk, the whole system would be inverted to harness energy from the flow of ocean currents and waves. The firm’s long-term goal is to build a large system in the United States. That can be on land or in the water.
