The MRI came from a chemist who had
just started to hang around physicists.
This is very common with field switchers.

moving blades on the inside of a rotating
drum and mount the combustor and
nozzles on the internal stator as with
all ER turbines.
Finally "boundary layer" engines can
become an efficient cheap low tech -- less
than $50/kW -- gas turbine that can
operate at lower rpms over a broader
range.
What's REALLY curious about this is for
a couple of years I was specifically looking
for anyone who had worked in both fields
to determine why turbo is so conservative
compared to electrical.
I knew about Tesla's work in both fields,
yet I never made the connection.
Now how did THAT happen?
