It's a vision of a magnetically levitated wind turbine that can generate one gigawatt of energy (enough to power 750,000 homes). This is the device proposed by a new Arizona-based company, MagLev Wind Turbine Technologies. The company claims that it can deliver clean power for less than cent per kilowatt hour using this wind turbine.
That's a pretty big deal actually. Today's energy is 10-15 cents per kilowatt.
