Also got a doorbell. Made a little housing for it with a piece from the zinc scrap pile.
The wireless doorbell is pretty clever: Instead of using a battery and finding out it's empty because you missed a delivery, it has no battery at all. Instead, it generates enough power to squirt a radio message to the receiver from the force of the finger pushing the button to ring the bell. Clever.

#Lithium is definitely not the answer, but only an interim option until we can find a better solution that doesn't cause the level of #environmental and #human damage of this rare material.
Could #zinc be a much better, and cheaper, way to achieve Everything, Everywhere, All at Once #ClimateChange mitigation?

Low cost, same performance as lithium ion, what’s not to like?

"The cathode is not made from the familiar mixture of #lithium and other metals. Instead, the primary ingredient is #zinc, which ranks as the fourth most produced metal in the world.
Eos’s batteries use a #water-based electrolyte (the liquid that moves charge around in a battery) instead of organic solvent."
This is intended to be a #GridBattery.
