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? Chris
