The Sky is the Limit!!
When it comes to wind turbine placement, there is a large untapped potential for energy generation 400-1000ft above ground. The concept involves tethered, very light turbines that are self-stabilized to adhere to Federal Aviation Administration guidelines. The rated power of these types of systems is generally small ~ 10-600 kW, however, the winds at these heights are more persistent providing a more consistent energy supply. Check out how this particular design works in this short video.
