True, however we already have highways in the sky. There are plenty of
stay-out zones for aviation, such as over military bases and such. The
number of aviation stay-out zones will surely increase. I can easily see
the advantages of hauling the power generation cables aloft, so that they
don't swat birds all over the neighborhood, and stay in contact with better
wind. A cable is much easier to build than a tower. I could imagine these
kinds of schemes eventually contributing a percent or possibly two percent,
to total power generation.
