Splitting water into hydrogen and oxygen is generally considered a fantastic way to get a renewable power source. The problem is how exactly you go about splitting the water. Current methods require some power input in order to kickstart the reaction, reducing its effectiveness as a sustainable power source, since power needs to flow continually in to the system. But a new technique could meld together a number of other methods and produce constant, carbon-neutral hydrogen from two things we have in abundance: fouled water and seawater. More »
