Jerry Scharf sez:
For those of you who have never had the pleasure of working with turbines,
they are not something you would want to be near humans who still want their
hearing. At about .5MW load, they have a marked similarity to a jet plane
taking off (no surprise.)
At least one Bell started using Solar Corp. turbines in CO's.
No idea if they still do. But they put them in places you'd think
they could not -- such as the top floor of downtown hi-rise, via
a hole chopped in the roof and *very* careful winching....
