What is all this talkk of particles blowing through the housing?  What
particles?  The original premise was that these flywheels disintegrate
into a light cotton like fiber.  Heat, yeah, but how much kinetic energy
does a flying piece of cotton have?
And there are ways of dealing with too much heat.  How about ceramic
thick films on the inside of the housing as thermal sheilds?  Or a
ceramic housing?
I think I'll look these up, does anyone have a reference?
