- 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

- 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
