Hi Jed,
What you didn't say in so many words, and I forgot to mention, is that using
wind energy has a positive impact in as much as it reduces the amount of CO2
produced.

I think that this is just nice to know study, but it does not put fundamental
limits for the wind power utilization. First is that with optimal scattering of
wind turbines, it is possible get significantly more watts per m². Linear rows
