Go ahead, build the lightest turbine you can, then tether it with the lightest 20,000-foot-long cable you can make that can transmit the electricty, and you won't be anywhere NEAR an amount of weight you can lift with anything short of a MASSIVE thinwing glider, which will catch the wind wrong for a second, the lift will slide off the wings and it will death-spiral along with that cable, beelining for a residential neighborhood near you.
Even if they had micro-nanotubes that could support the weight and deliver the power, or wireless power, or whatever, you'd still have mechanical failures and huge turbines plummeting into buildings (or ships if you put them over water).
This gets proposed every year somwhere, and it's just as dumb. There are a lot of good ideas out there and it's somewhat infuriating that perpetual-motion machines and microwave diamonds keep getting the attention.
Science journalists need to start INVESTIGATING things, not just mindlessly reporting the same nonsense every year.
