Kitemill is a company developing an airborne power turbine.

The turbines will use stronger winds at altitudes, using a fraction of the materials compared to a conventional windmill.

The kite flies in a spiral path pulling a tether attached to a winch on the ground. This generates electric power. The return phase is a lot quicker, so 80% of time is used for producing electricity.

The company started out using soft kites much similar to those used for kitesurfing and since developed a 5 kW prototype and 30 kW turbine employing a rigid composite design.

Futhermore their kites use use VTOL to launch the kite into production altitude and land.

Kitemill plans to build a wind power plant at Lista. It is the first company to get a permanent approval by the Civil Aviation Authorities to operate kite turbines 24/7 up to 300 feet.
