Nov. 8 - A Japanese inventor unveils what he calls the "next generation of eco-friendly energy sources" - batteries activated by water.

Susumu Suzuki, the president of Tokyo-based building material maker TSC (Total System Conductor), has invented water-activated batteries, which have an electric current as powerful as that of a standard manganese dioxide battery.

Suzuki says these batteries would be cheap to produce and can be recycled several times, making them an essential tool for the future.
