Pedal Powered PMA Concept Drawing
« on: December 28, 2006, 02:30:23 PM »


Hopefully this makes sense. Think of your basic dual rotor job, But with a sprocket on one side...  done correctly, this would replace the back wheel of a bicycle.  A chain connects to it just like a regular bike wheel does.  As for total width (diameter) of the rotors, it could be anything - 6 inches, 12 inches, 27 inches.


Am I off my rocker?  Would the chain bind because of magnets on the other side of a thick steel plate?  Would it be too hard to turn by foot?  


The reason for the idea of rear wheel replacement is that I could get high rpms with the right gears.  If you've ever turned a bike upside down and turned the pedal with your hand, you know what I mean.  Plus I'm spending more time on the treadmill, and though this big fat a$$ of mine might get smaller, I'd like to generate some 'lectricity while I'm at it.  :-P


There is a descrepency in the size of the sprocket-holed side of the bicycle hub and the inner diameter measurements of readily-available discs. The hub requires a disc approx 4cm (1 3/8") inner diameter, and the discs available from Otherpower.com have a 2.5" hole.  I have found places like Fastenal who have Washers with 1 3/8" ID and 3" OD.  Could these be used as a way to hook the two together?


If I'm all wet here, please let me know.  Help me avoid a potentially costly mistake.  I really want to do something with wind, but this pedal powered thing would be more beneficial (exercise) to me.


Thanks for all the help!

It might be easier to use undrilled steel rotors and drill your own holes. No washers, etc.The undrilled rotors are available from several sources, including windstuffnow, and they were available from nywindgenny,don't know if they still are but you could email and ask.

The best way to "kill time" is to work it to death!
