The mobile running out of juice just when you need to make that crucial phone call is a common problem the world over. There have been numerous science projects going on around the world trying to come up with charge- on- the- go options. The most recent and extremely interesting option in offering comes from Sweden.

Researchers in Sweden have come up with the first water activated charger which can use a puddle of water to charge your phone. The charger, which has been named MyFC PowerTrekk, is based on micro fuel cell technology that was developed in Stockholm at the KTH Royal Institute of Technology.

The head researcher Anders Lundblad feels that the invention which uses ordinary water has great potential to accelerate social development in emerging markets. Specially in areas which lack electricity but have access of mobile phones. The charger works equally well with both fresh and seawater.

The charger has an USB connector which attaches the charger to the mobile. Water is poured into the recyclable metal disc inside the unit. Chemical energy due to release of hydrogen is converted to electrical energy which is then used to charge the mobile phone. Commercial applications for the science project have unlimited potential.
