Making a Case for Flywheel Energy Storage
The principle behind the flywheel is that a relatively small generator can spin up or charge a flywheel over a period of, say, a minute and then take the power off the flywheel over a period of several seconds. Because it takes about a minute between aircraft launches on an aircraft carrier, the flywheel can be charged during this time.
