If every portable device used the same batteries, and every battery could be recharged - surely the amount of electronic waste dumped each year would drastically drop.
This is the notion behind the Green Cell concept.
The team behind the project made the sensical statement that the environment would benefit from fewer batteries being thrown away, and device users would need fewer chargers for all their gear.
They add that the batteries themselves would be environmentally friendly by not using any toxic chemicals.
They will also be sold from vending machines that double as recycling points.
But will they be able to persuade manufacturers to configure every gizmo to the size and voltage of standard rechargeable cells - I hope so.
