Science is Fun Fridays!
China has tested the world's first megawatt-class flying wind turbine, generating enough energy to power an average home for two weeks. Dubbed AWES, it is a large helium-filled airship containing 12 wind turbines. It utilizes stable wind speeds at an altitude of 6,500 feet. The idea wouldn't be to have one over every house though, but to complement traditional ground-based wind power systems, and potentially for use in off-grid settings. Testing is in early phases, there is much to consider with regards to maintenance and safety, such as the tether's risk to aircraft.
