Drink cans made out of Nitinol, after use, could be placed over small induction heater spots near purchase points to shrivel back to a coin shape. Several of these tokens could be redeemed to buy a new beer or other products. This should give a boost to recycling because of its small size and by being a valuable, literal, deposit currency.

       Had we but world enough, and Nitinol,
This coin-ness, Farmer, still wouldn't work at all.
  

       Doesn't seem to matter though, the FJ Universe has its own internal coherence. A miraculous place. The skies are always some electric-pastel color; there is no litter; everyone walks jauntily...   

       +1 to the ongoing FJ Universe Project.

       "Ha!" said Farmer John,
As he munched off his spork,
"He started out po
But he ended up pork."
