Replacing conventional fuels in the automotive field is now an old story but something similar happening in the field of electronics definitely sounds interesting. In a way the mobile phones and other electronic doodads could go hybrid with he use of a Samsung micro-generator that powers mobile fuel cell hydrogen ultimately powering the devices for a period of 10 hours but not before exuding a small amount of water.
The turning on of a gadget viz. a cell phone will see the internal components reacting to produce hydrogen which then reaches the fuel cell to react with the oxygen eventually producing electricity. This amazing technology would be improved upon considerably before it expectedly reaches the consumer by the end of this decade.
