MyFC PowerTrekk - Charge Your Cellphone With 'Water-Powered' Charger
It so happens that the scientists from KTH Royal Institute of Technology in Stockholm used a micro-fuel cell technology and some ordinary puddle of water (fresh from tap or a mug full from the sea) to extend the life of a battery used in devices of up to 3 watts. Anders Lundblad, KTH researcher and founder of MyFC, even says that the water need not be even completely clean. How does this thing work, you wonder? Well, a USB connector attaches the compact PowerTrekk charger to the device. When plain water is poured onto a small recyclable metal disc inside the unit, hydrogen gas is released and combines with oxygen to convert chemical energy into electrical energy. The resulting charge is enough to power an iPhone to between 25-100% of its battery capacity.

If that isn't amazing enough, you would love to know that the team of researchers is now aiming towards building fuel cells in laptops. Though a bit expensive now, it is only a matter of time when fuel cells reach the masses and prices come falling down. And not only eco-friendlier than any other resource you can think of, Lundblad claims that these fuel cell chargers are faster and more reliable than solar chargers.
If you are at - Shut up and Take My Money - already, let me tell you that MyFC does plan to open an on-line shop for its MyFC PowerTrekk product. The product is already being bought by enthusiasts in China, Japan, the US and Europe.
