Recycled Batteries

The mind was wondering this afternoon and thoughts soon turned to creatively recycling. I remembered reading a project regarding the making of a Joule Thief which involves using a simple bit of circuitry to squeeze the last remaining juices of power out of dead batteries.

As we’re all encouraged to dispose of our spent batteries separately to the usual domestic waste, surely local councils could rack them all up at a central depot and Joule Thief them to death. The quantities of batteries thrown away on a regular basis must be staggering and this will ensure we get the most out of them.

As high intensity LEDs are replacing standard bulbs in more and more places, could we not do the same to say street lighting and power them off these banks of spent batteries. I’m also sure that if power fails, the lighting could resort to conventional means as a back up.
