I wonder if the glass container the spinning armature is in has a vacuum to help reduce air drag and thus power requirements(and maybe noise?)

  I wonder how noisy it is - it would have been good to include in the specs.

  No, the enclosure keeps the air contained and moving at a constant rate with the armature. The only noise comes from the brushless motor, which is under 50dB at 1m.
