But don't you worry about charging your phone while there is no power source. You have water. Whether it is dirt water or clean water both will work. Who made this freakin device? Sweden Stockholm's University of KTH Royal made this great invention "Water Charger" which will work on water. Micro-foil cell technology used in this device which can generate 3 WATS of electricity. Researcher said, when water get contact with metal disk (i exactly don't know what is this ingredient,magician never reveals his secret) in this device it will cause to create Hydrogen Gas. When it mixed with Oxygen its chemical reaction generates electricity and this will charge up the battery. This technology will be used far in the future for laptop. This is the device: This technology is known as "Power Trek"
