I hadn't heard of ANYONE doing this for any serious energy storage (most
reciprocating engines use flywheels to smooth out the motion generated, of
course, but this would be different). Do you have any info on where you
heard this?

Some diesels use dynamic (generated current from the traction motors is
dissipated through large resistors) braking, some don't... it depends on how
much braking is expected to be needed.

Cool!
