A hydrogen powered calculator!? Amazing stuff. This product is eco-friendly, provides free energy and has a replaceable H2O cell.
The great thing about a H20 battery is that each component is recyclable unlike conventional dry cell batteries. Usually the recycling of such dry cell batteries is not just expensive, it is incomplete which results in pollution and damage to our environment.
