Fighting the windmills, of course.
Shouldn't that be that Tilting at Windmills?
I understand that the concept is sound for power generation. Karl's
talking about turning his roof into a solar convection tower of sorts,
but you'd probably need to go big or design the roof specifically for
that purpose to get enough air flow to provide significant power eg.

see "towering heat." There's an Austrailian company planning to build
a solar tower based on this idea in the Outback. Can't find the web
site reference for that one though.
Still, it might be a fun home energy project to investigate once I get
through trying to brew butanol in my garage.
