Best wind turbine designs that promise to generate green energy
Energy efficiency and more and more use of renewable energy sources is the only mantra to survive the rough tide, which asks us to seek newer ways to cut down on our energy needs and suggest innovative ideas to gain energy efficiency. Wind energy undeniably is one such renewable energy source that needs to be exploited more and more to realize a greener future.
Here is a list of five wonderful wind turbine designs that promise to generate renewable energy with a difference:
- Whale Power
Inspired by the tubercles or the bumps present on the fins of Humpback whales, the company called Whale Power redesigned their normally smooth blades of a wind turbine by adding a whole new series of ridges. The company reports that the new blade design will result in 20 percent increase in annual electrical production. This new structure prevents the turbine blades from causing stalling and producing too much drag and helps the blades to achieve steeper angles, which results in generating more power even during low winds. Therefore, with this new eye-catching design, Whale Power seems to have achieved a milestone in generating more power with minimum wind.
Windspire is a new state-of-the-art vertical wind turbine with a 30-foot tall body and a 4 ft wide wind turbine. This new wind turbine can generate 2000kilowatts of power per hour with a wind blowing at 12 meter per hour. Besides this, Windspire can also survive strong winds blowing up to 105mph. The wind turbine is installed with a tall and thin propeller-less rotor which generates power by spinning its vertical airfoils. Many schools, businesses, museums and county homes across the country have already been using Windspire for generating power.
- Quiet Revolution qr5
The Quiet Revolution qr5 wind turbine has been designed keeping in mind the urban environment that generally experiences an ever-changing wind direction and low wind speeds. Unlike the traditional wind turbines, which generally capture horizontal winds, the qr5 has been purposely designed helically so that it can collect wind equally blowing in all directions. Throughout the United Kingdom, almost 70 qr5 were installed in 2008. According to reports submitted by the company, each unit has been successfully producing 4000-10,000 kilowatt hour every year.
Designed by the PM Breakthrough Award winner Shawn Frayne, the Windbelt is a small structure of wind turbines that generates 40milliwatts of power at 10mph wind. It is mainly designed with an aim to help the poor people enjoy power safely and by spending only a few bucks. This Windbelt generates electricity by the oscillation of two magnets, which are fitted between a pair of wire coils on a membrane.
- Honeywell Wind Turbine
Honeywell Wind Turbine is one of a kind rooftop wind turbine, which can generate electricity even with a wind blowing at a low speed of 2 miles per hour, and it is mainly designed for businesses and homes. Like most of the wind turbines, the Honeywell turbines are not fitted with gears but the tip and the enclosure of the turbine blades are fitted with magnets in order to produce power. According to the company, this unique design allows lower resistance and therefore results in higher energy output.
