Sorry, Carl.  But this description of a lightweight composite Flywheel Battery
comes from A cutaway drawing by some manufacturer in the last issue of Popular
Science.  It clearly demonstrated a central metal axle shaft, the composite
flywheel, and the coils for electric power transfer.  Unfortunately I have neve
r
obtained a CRC Physical Sciences reference book and I am a bit weak on various 
heats of melting and vaporization.  Some crude calculations showed that to go
600 miles at 60 mph might take some 100 to 400 MegaJoules.  Nothing to snitch a
t
I agree.  However this would be non-stop driving.  which is contrary to the 
intended use of these vehicles in stop and go city driving.  What  reduction 
factor would be introduced by regenerative braking?
Still, I return to my original opening remark.  I have some faith in the engine
ers
responsible for designing Flywheel Batteries...
Bye...  Ted..
