Samsung has developed a new mobile phone battery which is powered by water and aims to bring this battery to the market by 2010.
When the handset is switched on the reaction between metal and water in the phone will produce hydrogen gas. This is then channeled to the fuel cell where it reacts with oxygen in the air to generate power.
According to Oh Yong-soo, vice president of Samsung Electronics Mechanics' research centre, the new battery could last for up to 10 hours, adding that based on four hours of use daily on average, the hydrogen cartridge will have to be replaced about every five days.
The next development would then be to eliminate the hydrogen cartridge altogether and to rely only on water.
