Blimp-lofted wind turbines: huge return on investment

This awesome-looking prototype of blimp-lofted wind turbine can apparently achieve significant energy return on costs by being tethered high above the usual 300ft ceiling presented by ordinary tower-based turbines, delivering power for up to 65% cheaper than conventionally-built wind turbines that produce the same power. And that 65% figure assumes a height of 1000ft — …
