HydraCell energy cells are one of the most exciting technologies we’ve seen in decades, and are set to change the world. They behave just like batteries, but instead of lead and sulfuric acid, they work using just tap or sea water. Unlike other batteries, which start to deteriorate as soon as they’re manufactured, each HydraCell has an amazing 25-year shelf life until activated with water. It will then last for up to 300 hours of active use as long as you immerse it in water for a few seconds if it runs low on power. The HydraCell doesn’t degrade like batteries either, so it works constantly at full power until it needs re-dipping in water.
