Water Powered Calculator
One of the best eco items we've seen recently is this water powered calculator. It is powered by a revolutionary water battery which uses two electrodes made of special alloys which generate electricity when immersed in water.
When the battery runs out as the water evaporates, just refill it! The water tends to evaporate in around 2 or 3 months.
The battery has a minimum continuous life of one year, typically 2 years. They can be dried out and stored at any time to increase their life indefinately.
