A bicycle power generator
Now, I figure there's not gadget made yet, but I was wondering what the actually probability of tying up a generator to the grid would be? Easy? Hard? Anyone have any DIY resources?

Instructables has a lot of ideas. I would think you could use those and hook them up to a grid tie inverter without any problems.

As I recall, there are some kinds of induction motors that will push back into the grid just by pushing them a few %rpm over their rated speed. Connected with a freewheel and some gears to your crank, and it seems real doable.

Not aiming for grid tie, but I'm going to tackle a bike based DC generator: http://ecorenovator.org/forum/applia...generator.html

The contraption is mostly still together, minus the motor. So I took some pics of it. The dc motor is a 1/2 hp 100v 1800 rpm (still wrong for my ratio). I imagine a dc treadmill motor would be an excellent choice for the ratio my set-up has. Or one could make a larger roller that contacts the bike tire to better match the generator. The induction motor is boxed away so no pics of it.
