Delft professor puts kites high on list for renewable energy
Energy from the windy heights
The electricity from our sockets could soon come from a high-tech device flying in the sky. The innovative research project to generate wind energy with the aid of a kite won over the "Venture Kick" jury; ...
Electricity in the air
(Phys.org) -- The faster a wind turbine's blade spins, the more energy you can get from it. And the farther you get from the hub, the faster that part of the blade is traveling. So the tips of the blades generate ...
Ancient walls reveal evidence of mass gazelle slaughters
Want to save fuel? Fly a kite, German inventor says
The blue-hulled vessel would slip by unnoticed on most seas if not for the white kite, high above her prow, towing her to what its creators hope will be a bright, wind-efficient future.
Fiercest birds make the best home decorators
You might raise your eyebrows at their choice of material, but you wouldn't want to pick a fight with a black kite whose nest is adorned in white plastic, Spanish researchers said Thursday.
Toy Makes Gathering Wind Data A Breeze
Meteorologists have developed a portable new tool for measuring atmospheric wind speeds by tethering kites to ground-based metering systems.
Sensing wind speed with kites
Kites have a storied history in meteorological research -- think of Benjamin Franklin and his study of electricity -- including being used to carry aloft sensors that measure wind speed. Previously, however, these sensors, ...
Weather kite gets second wind
The red kite is now a commonly-seen bird of prey in the skies of the south-east, but a specially designed artificial blue kite promises a new way to make weather measurements.
Kites flying in high-altitude winds could provide clean electricity
(PhysOrg.com) -- At any moment, the winds in high-altitude jet streams hold roughly 100 times more energy than all the electricity being consumed on Earth, according to a study by Stanford environmental and ...
