Wind turbines have a lot of opponents, and lots of regulatory hurdles that they must go through between initial proposal and final approval. One particular difficulty has been from aviation authorities (both civilian and military) whose radar can pick up interference from wind turbines. These objections have led to many wind projects being delayed or shelved indefinitely. But solutions are being developed that may allow wind turbines to theglobalobservatory.org coexist with radar.
The moving blades from wind turbines can cause intereference to show up on radar displays.
"At one stage trade association Renewable UK estimated that around 40 large wind farm projects were being delayed because of objections from the aviation sector." Given the wide expanses of open land in the US, the problem has been less of an issue, but as more wind facilities are developed for locations close to population areas, the problem is likely to become more of a concern. In the UK, a software solution is female levitra being explored that will enable air traffic controllers to differentiate between aircraft and wind turbines.
Another possible solution is to build turbine blades with material that is not radar reflective. Using composites that either absorb or scatter radar beams would make the turbine blades invisible to radar.
