Wind

Researchers from the Chinese Academy of Sciences have developed a new type of wearable electric generator, which harvests energy from the wind as you walk. The team says it’s low cost and efficient enough to power small sensors and LEDs.

A new study looking at nearly four decades of data has shown that in almost every part of the world where hurricanes form, their strongest winds are getting even stronger, with global warming thought to be a key contributing factor.

The Trijicon Ventus looks like a set of binoculars, but in actuality it's the world's first hand-held device capable of providing three-dimensional wind data at multiple points between a shooter and a target up to 500 yards (457 m) away.

​Wind storms can cause a great deal of damage to coastal areas, producing waves that erode the shoreline and destroy facilities such as marinas. A newly-proposed "floating forest" could help, however, by blocking both the wind and the waves.

In 2014, US Army engineers Charles Marsh and Carl Feickert envisioned a wind-power system inspired by fluttering Venetian blinds. They have since teamed up with eight colleagues, creating a system that generates power in breezes that are too light to turn the blades of a traditional wind turbine.

A new satellite built by the Europeans Space Agency has now slipped into orbit, and will soon start using a sophisticated instrument to bounce lasers through the atmosphere to paint a more detailed picture of global wind patterns than ever before.

​Last year we detailed how Norsepower had rediscovered an engineering innovation, which sees large cylinders installed atop big ships harness wind for propulsion. Now a passenger ship has been treated to the Rotor Sail Solution and has set sail on wind-assisted trips between Finland and Sweden.​

Finnish company Norsepower has looked to the past for inspiration in making modern shipping more environmentally efficient, finding a solution in a nearly century-old engineering innovation relegated to the annals of quirky mechanical history.

Employing dual oscillating blades that mimic the figure-8 motion of the wings of a hovering hummingbird, Tyer Wind's new and quirky turbine has a compact design that's a potential fit for residential use.

Solar chargers are one means of keeping a smartphone charged when in remote locations, but they're dependant on hours of daylight and sunlight intensity. Portable turbines are an alternative and product designer Nils Ferber has created one he says is more portable and effective than any other.

The prolific Studio Roosegaarde has followed its Smog Free Tower and Waterlicht projects with a work that combines their respective environmental and light installation elements. Windlicht seeks to show the beauty of green energy by linking the blades of neighboring wind turbines with LED beams.

A freshly built indoor tank designed to study category five storms is now open for business at the University of Miami. As the only one of its kind in the world, it is hoped to bring a new understanding of these destructive superstorms.
