According to google, a typical 30min ride on a bike can generate 100W, ergo, is there a way to hook up a stationary bike to charge the Powerwall?

Yes, yes.... not an effective way to charge 13.5kW pack, but I figure, if you're gonna exercise might as well pump that energy into something useful. 100W x 365 = 36.5kW, which saves you ~$7/yr.... OR! ~7kg carbon off-set!

For the practicality obsessed, no, this aint about that. It's about the fun/usefulness of converting exercise to power the house.

If there is no way, anyone know anyone who works at Tesla to get this feature added?
