States can even be upwind for some emissions and downwind for others.
But Team USA refrained from using the technique, which requires boats to sail at 45 degrees to the wind and to turn frequently, while going upwind, for fear that they would lose speed while turning.
According to Shigeo Yoshida, who is in charge of research for the project, that makes the arrangement 5-8% more efficient in such circumstances than an upwind turbine would be.As a bonus, the downwind design is less temperamental in high winds.
This could explain the curious fact that precipitation in the western Amazon is higher than it is upwind, despite leakage in run-off at every revolution of the local water cycle.The theory caused a stir in Western academia last year when it was put forward in the journal Bioscience and is considered far-fetched by many.
That is because the blades, being behind the pole and at an angle to it, can be given more freedom to yaw about than they would have in an upwind turbine.
This is called an upwind design.Technology Quarterly Look into my eyes Any mileage in the idea?
Dr Mikkelsen is working on a way for individual turbines to scan the air upwind and adjust their blades in anticipation.The basic technology, called lidar (short for light detection and ranging) has been around since the 1970s.
And on August 21st a different appeals court struck down the EPA's cross-state air pollution rule, a 2011 measure designed to protect states from pollutants emitted by coal- and natural-gas-fired power plants in neighbours upwind of them.Both conflicts were almost inevitable.

Beijing has been struggling to improve its air quality, even as industries upwind in Hebei spew noxious fumes in its direction.
