Provide manual shredder energy from a bicycle ?

Hey Dave,
I have more faith in human kind when I stumble on people like you. I am really glad I found your videos on Youtube.
I had a thought or two…
What about making the shredder more accessible to poor people, usually the places where there is way more plastic available….
1- What about swapping the shredder electric motor for a bicycle, using a multiplied bracket ? Poor people without electricity could make a home business of simply shredding plastic from a bicycle then sell shredded plastic bags to other business entities.
2- What about a large wheel, like a cargo boat captain wheel, so that people could make the shredder work from just rotating that wheel with their hands ?
Poor people could not only shred plastic, but also wood…
Just for fun, found on thingiverse…

When I read your topic I remember some interesting machines, which I‘ve seen in Kenya (2014). Fortunately I made some photos:)) We went to the market an I saw this grinding stone application in front of a butcher’s shop:) Pretty awesome because you can even ride it like a normale bicycle.
Also the second picture is very interesting. It looks more solid and is also made out of bike parts.
I think it’s possible to use these systems to shred plastic. I like the idea to use the shredder without electricity; especially a shredder which is easy to move. So you can shred the plastic where you find it. In fact it could be a lot easyier to transport the cranulated plastic. I personally think about a shredder fixed on a cargo bike.

@philgib I will be working on this as well the upcoming months!
Happy about every exchange! 🙂
Dave has a video floating around somewhere of some versions of the machines he built for an exhibit. To make them safe they are covered in plexiglass and the shredder and injector use a turnstile-esque crank. I looked around but couldn’t dig it up.
Welcome to Precious Plastic @philgib
Those ideas are absolutely feasible, in fact, @simonm already did it and it worked just fine: http://onearmy.world/community/forums/topic/my-shredder-construction-log/
Take a look at his post, is full of interesting info 😉
