New SUSTAIN wind-wave research center creates roaring indoor hurricanes

Scientific curiosity around how air interacts with the ocean in the event of powerful storms has inspired a number of wind-emulating facilities around the world, from a high-speed wind-wave tank at Kyoto University to the Hydrodynamics Laboratory at Imperial College London. But just as hurricane season kicks off in the US, a team at the University of Miami is looking to step things up a notch. A freshly built indoor tank designed to study category five storms is now open for business, and as the only one of its kind in the world, is hoped to offer a new understanding of these destructive superstorms.Read More

Artificial Wind Tree provides a fig leaf for unsightly turbines

Generally speaking, the peculiar appearance of wind turbines coupled with the fact they perform better when up high and out in the open sees them banished to uninhabited countryside, or even out to sea. But a French entrepreneur believes that sculpting them in the form of an artificial tree could lead to wider adoption in urban centers, making use of low winds that circulate around buildings and streets.

Could great walls prevent tornadoes forming in the American Midwest?

The Great Wall of China was primarily built to keep out nomadic tribes, but a new study suggests constructing great walls in the American Midwest could keep out a different kind of threat – tornadoes. It might sound far-fetched, but a study conducted by Dr. Rongjia Tao from the Department of Physics at Philadelphia's Temple University suggests there is in fact some scientific merit to it. Strategically placed, 1,000 ft (300 m) high great walls could negate the forming of the destructive wind storms in Tornado Alley, and by extension, the destruction they leave in their wake.

Lockheed Martin WindTracer system to improve airdrop accuracy

For a besieged soldier or a disaster victim, a plane dropping supplies is the most welcome sight in the world – unless the drop ends up drifting off out of reach. To help make sure that airdrops end up where they belong, the US Air Force Research Laboratory has awarded a contract to Lockheed Martin to adapt its WindTracer wind measurement system for a Precision Air Drop system to help aircrews land supplies faster and on target.Read More
