Recharging the Battery

Years ago, we recharged nickel-cadmium batteries for use in various toys. Today I have many devices with re-chargeable lithium ion batteries.

These are fine things for inanimate objects. It’s good to have an energy source to keep them functioning without having them plugged into electrical current.

But what about you? Or other living things. How do they recharge?

On a recent sunny afternoon the snow leopard and a zebra enjoyed a solar re-charge.
