When they were running the Tokamak fusion reactor at Princeton University, they had two 100 ton (not sure about the weight) flywheels in the floor that were brought up to speed and then unloaded through the reactor. Their current creation was enormous (again, don't know the exact number), but was told by the tour guide that without the flywheels, the load would have blacked out Northern NJ.

It's been a fun thread with lots of interesting posts, despite the OP going AWOL. It's probably time to tie off the thread, though. Thanks for the posts.
