Remember that giant solar tower power plant that is
being constructed in western Arizona?
Wouldn't it be great if we could get that energy
production without having to build that giant tower?

Note that they are NOT recommending using dedicated
heaters to produce the required warm air - that would probably be

industrial plants. The Atmospheric Vortex Generator makes it possible to
extract significantly more energy from that waste heat.
