I got kicked out of Cal Courts this morning because the power went out and they didn’t think they’d be able to restore it for 20 minutes or more. It made me think again about what it would take to tie all the machines at a gym in to an electricity generating and storage system. All that kinetic energy going to waste.

Of course, at 8:30 on a Sunday morning, there weren’t enough people at the gym to create enough energy to run a flashlight, let alone get the lights back on. And I suppose that’s the real problem. We still don’t have economical and efficient energy storage systems (batteries) to make this, and most other alternative energy systems cost effective.  It seems like we really ought to be throwing a lot of resources at energy storage systems.
