Are These Giant Flying Turbines the Energy Answer?

U.S. based Altaeros Energies has developed an airborne wind turbine, hovering more than 1,000 feet off the ground, avoiding the usual complaints about a spoiled landscape from regular turbines. The project may be hampered by concerns of U.S. regulators about the tethered turbines interfering with flight patterns. Video courtesy Altaeros Energies.
