Why haven’t we already built hundreds of these things? We’ve had the technology to do this since the early 20th century. Unlike solar power – which is very good for keeping up with demand during the day – the wind at higher altitudes doesn’t stop when the sun goes down. These things would also pay for themselves in a very short amount of time compared to coal, nuclear, or any other power plant that requires the purchase of fuel. I say get started on this yesterday. What do you guys think?
