The use of wind turbines become a necessity because it claimed to be alternative energy solutions that are environmentally friendly.
Recently, an Australian company, Renewable Energy Solutions Australia (Resa), it managed to make Eco Whisper Turbines, wind turbines are designed using many of the rotor blades are interconnected by two rings at the end of the rotor blades and the pertengahannya.
This design is no longer using the tail to drive the turbine diameter is 6.5 meters in the direction of the wind. Environmentally friendly system that was adopted came from the addition of the rotor as much as 30 pieces with 2 rings.
The company stated at the end use of the rotor is claimed can reduce the noise generated significantly.
In addition, the 21.1-meter-high tower that is used is also designed to be laid starting from the middle.
The goal for wind turbine maintenance is easier and avoid the extremes of wind above the limit of his ability, although wind turbines are designed to withstand winds of 220 km / hour.
Resa also claims the wind turbine with a capacity of 20 kilowatt electrical energy can produce 45,000 kWh per year.
Unfortunately Resa does not clearly indicate what percentage of noise that it generates compared to other wind turbines. (c8/lik)
