MIT Researchers Harness Viruses To Split Water

ByronScott writes "A team of researchers at MIT has just announced that they have successfully modified a virus to split apart molecules of water, paving the way for an efficient and non-energy-intensive method of producing hydrogen fuel. 'The team, led by Angela Belcher, the Germeshausen Professor of Materials Science and Engineering and Biological Engineering, engineered a common, harmless bacterial virus called M13 so that it would attract and bind with molecules of a catalyst (the team used iridium oxide) and a biological pigment (zinc porphyrins). The viruses became wire-like devices that could very efficiently split the oxygen from water molecules. Over time, however, the virus-wires would clump together and lose their effectiveness, so the researchers added an extra step: encapsulating them in a microgel matrix, so they maintained their uniform arrangement and kept their stability and efficiency.'"

    I can just see it now. Some of these get dropped into an ocean, multiply, and eventually deconstruct the majority of the world's water into oxygen and hydrogen. It's the end of the world!!

      Even if viruses could reproduce without a host (they can't), when oxygen mixes with hydrogen, the hydrogen oxidizes (burns) instantly. The exhaust from burning hydrogen is water.

    Perhaps they could use light as the energy source required. You could even make sugar with it! But you'd need to collect the sunlight - since red and blue are the highest-energy colors, it would need to be a green pigment.
