#2009: ChargeChange

E-waste is a growing problem. Batteries especially are generally hard for consumers to get recycled and end up getting dumped in landfill.

Today’s invention is to adopt one of the large circular batteries as a unit of currency.

Equipment manufacturers could design their kit to run off several of these. To operate your phone, it would be just like popping in some loose change.

When they can no longer be recharged, people are still going to hang onto them to use in making small purchases (perhaps tied to other green recyclable goods).

The battery cases would need to be stamped with some kind of hard-to-fake symbolism (at least as secure as current coinage).

Ultimately, they will all get returned to banks, which can act as collectors for the major recycling programmes.
