Greg, I've meant to ask you about photo ever since I saw it (which was
some time ago!).

Is it a central vac motor, or from something else?

In your photo, how hot was the gas by the time it got to the suction
blower?  (since I can see any cooling, other than that from the ~10' or
so of bare metal pipe)

Are the blower's impeller, housing, bearings etc able to handle that
temp for extended periods of time?  (I know you made quite a number of
endurance runs)

Do you control your gas flow rate entirely by varying the blower motor's
speed, or do you also throttle it?

Cheers,
