Simple blade attachments could solve one of the biggest "NIMBY" objections to wind power.
Noise pollution is a big public concern when operating wind turbines. A group of European scientists claim to have found a solution to this problem,an innovative device that attaches directly to the turbine blades. They are collaborating with a European project called Windtrust.
Technicians at a Spanish windfarm near Burgos are assembling the device, which looks like a serrated cutout.
Furthermore, researchers wish to optimise the use of carbon fibre to build the blades, increase their durability and reduce weight, the aim being to help extend the overall service life of turbines. At the same time, near Madrid, researchers are testing the so-called “Wind converter," a device that transforms the mechanical energy of the blades into electricity.
Technicians wish to maximise the balance between energy generation and machine service life. Wind power technology engineers have to face a number of challenges: discontinuity of supply due to weather conditions, difficulty of energy storage, impact on the environment, high costs of energy generation and maintenance of equipment. Increasing the effectiveness and durability of turbine components will contribute to a better and more widespread use of wind energy.
