11,000 RPM is about right and yes, just as turbines
have a huge appetite for fuel, they have just as huge
an appetite for air.
no way they filtered the inlet air; the turbines would
just be eating raw outside air, and blowing it back outside

the radioactive contamination not having any effect on their
I have experience with turbines in a bunch of different uses,
and the amount of air that they pull is ASTOUNDING.
A big engine (GE J79 for example) is eating 150 pounds of air
a second. most people think "PSI" - but that is not this - this is
150 pounds of air by weight per second, or roughly all of the
air in a small building, per second....
The solar is a lot smaller than a J79, but that just means that
it would eat all of the air in a building in 5 seconds ;-)
fun things they are!

Doug at one point owned an engine; was that a J79 or something else?
Speaking of surplus; I just found out my friends in NorCal have a Diesel
genset from a CO in a back storage building.....a 750KVA unit.
That's ~60gal/hr of #2....gulp.
