Shopping Bags to Frisbees Answered
Someone once told me that about the only way to join polyethylene plastic was with heat and pressure.
Plastic shopping bags are a recycling problem. I think they are polyethylene plastic. Heat and pressure might turn them into Frisbees, or other essential things.
I visualize a vertical, heat-resistant cylinder with a removable Teflon-coated bottom cap in the shape of a Frisbee -- black to absorb solar heat. A piston inside with the other half of the Teflon-coated mold could have a weight on it to provide pressure.
Fill the cylinder with shopping bags, with the piston inside, and suspend it over a solar reflector to heat the end cap of the cylinder. There you have heat and pressure -- and free energy to turn the shopping bags inside into Frisbees, or other objects.
Personally, I don't have need for more Frisbees, and don't collect enough bags to keep the equipment busy. On a community recycling scale, though, it might be a way to get rid of a lot of bags that nobody wants.
Would anybody like to run the experiment?
