What is water power?
Water power is the latest in ecological and environmental design. Incorporating dependable water powered technology to power the digital products that we use in our everyday lives. This innovative, patented technology runs purely on water.
Unlike many solar powered calculators there is no loss of display clarity in low light conditions.
How does it work?
To maintain a constant supply of energy simply refill as the water evaporates, typically every 2 to 3 months. The H20 battery has a minimum continuous life of at least 2 years. In addition to this, the H2O water battery (unlike all conventional batteries) can be stored in it's dry state indefinately and can be left to dry out at any time during it's life and it's life extended indefinately.
As all of the components of the H2O water battery are recyclable, the benefits over traditional batteries are countless. Every year billions of conventional dry cell batteries are used, and the recycling of such waste is not only expensive but often incomplete, resulting in hazardous pollution and damage to our environment.
The H20 Compact Calculator is designed and manufactured with both professional and home use in mind. By just adding water you are providing your product with an endless source of energy. At the end of the H2O battery's life (indicated by dimming of the display) simply replace the battery and start all over again. Replacement water powered batteries are readily available from Ecofreak.
