Efforts to promote and develop new forms of sustainable energy have pushed wind power to the forefront. However, this type of power comes with a cost — as it often interferes with birds’ and bats’ migration, killing hundreds of thousands of these winged species.
A downed turbine is a money-losing turbine, and so knowing the current status of a wind turbine at any point in time is important for achieving a high uptime record. Sensors on a wind turbine therefore are extremely important for managing the production of the machine. But there are many challenges for sensory technology on utility scale turbines, including the (more…)
An Australian company called Renewable Energy Solutions Australia Holdings Ltd. (RESA) has created what it says is a super quiet and efficient wind energy turbine.
Suggestively called Eco Whisper, the wind turbine employs 30 smaller ones capped with a specially (more…)
What is a wake? It is small island in the Pacific. However, in this case it is the region of recirculating air flow immediately behind a moving solid body, caused by the air flow of surrounding air around the wind turbine. The air turbines not only produce power, they produce wakes — similar to what forms in bodies of water — that are invisible ripples and (more…)
According to Phoenix, Arizona resident Dick Hales, the turbulence created by commercial jets sitting on the runway waiting to take off is a prime source of wind energy, but to date no one has thought of a way to harness it.
Jets sitting on the runway pre-takeoff can create wind speeds of up to 300 miles per hour. In the United States, where about (more…)
