Finding new green, clean energy sources to replace fossil fuels is one of man's toughest challenges. Hydrogen is a viable replacement, but it doesn't occur naturally and uses energy getting it... Until now.
A group of scientists found bacteria that could extract hydrogen and give it off , but fuelling the bacteria was also the problem. The process of desalination used energy, so they thought that resalination would release energy. It worked; if they managed to put some bacteria between the sea/ocean and a wastewater treatment centre, it would be a dream. However, this has only worked in a lab and so now they go on to larger scale, and on the economic scale. If it works on all scales, we would be one step closer to the best species on Earth (possibly)
