The Icelandic Cauldron
At this point most people know that a volcano erupted in Iceland spewing forth tons of ash that have grounded countless flights.

The U.S. Air Force is threatening to halt construction of a 845-megawatt wind farm in eastern Oregon that would be the world’s largest wind project, citing concerns that the wind turbines would interfere with a nearby military radar station and its ability to detect radar images. Rotating wind turbine blades could impart a Doppler shift…
