Unfortuately there was no illustration, no description of the way it would be built. But I can
readily imagine heat accumulating, and air in great volumbe rising through the tower in the
middle, driving really large turbines and speed and power greater than it is possible to get
with a simple wind farm. And it wouldn't kill any brids, as the wind warms do. One thing that
was not discussed would be how to profitably use the electricity, such a distance from any city.
