Yesterday afternoon my son received some disc-like car parts in the mail. He explained to me what he was replacing in his car and compared how heavy the old part was to the new aluminum part. I mentioned something about using the heavy parts, somehow, as a weight on a flywheel for a kick wheel. Taking that idea many steps further, he drew me a diagram of a potters wheel run by a car engine. He's watched too many episodes of Top Gear - the UK version-especially the episode about a car engine rigged to power a "man's" blender!) At the moment, I believe I will stick with my electric Brent wheel. What a wild idea though. Also, he's not a bad artist for an automotive technician.
