Going aloft for wind power
In another twist on wind power, inventors are designing kites and balloons to generate electricity.
The wind industry is undergoing rapid growth as utilities, prompted by government incentives, seek out cleaner sources of power generation. Typically, these commercial-grade projects involve large wind turbines, which stand 100 to 400 feet high.
Kites and balloons are not widely used, and they face some of the same challenges as traditional wind turbines, such as bird deaths and complaints over location. But that isn't stopping people from coming up with "flying" wind generators.
