The calculator of tomorrow, today! The water-powered calculator.

Batteries really haven’t changed much over the years, only going through a few big changes every few decades. Even still, they’re wholly inefficient and toxic to the planet. But a water powered calculator with some unique new age batteries could go a long way to making this planet happier…

“Powered by water?” — you say. Yes. It’s actually not that complicated. The batteries that power this calculator are simple capsules filled with water and interact with two electrodes, causing a chemical reaction which in turn produces the electrical juice we all crave so desperately.

The best part — when the batteries are dead (all the water evaporates eventually), simply refill with water and viola!

$10.99 and it’s yours. Step inside for the links…
