Multifunction H2O Clock

Water powered, multifunction clock - displays time, date, day, year, temperature and can be used as a countdown timer and alarm clock.

The patented technology utilises two electrodes, one positive, one negative. When immersed in water an electrochemical reactions takes place (make friends with a scientist for proper explanation!) and this results in the production of electrical energy.

Just refill as the water evaporates, typically every 2-3 months. The H2O water battery has a continuous life of at least 2 years. All the components of the battery are recyclable, a big improvement on standard batteries - billions of which are dumped every year and are full of toxic chemicals.

Incredibly handy item to have!
