Hydrogen is a clean fuel source, but current methods of producing it, often by converting natural gas, can undo any environmental benefit. Producing hydrogen out of sunlight and water doesn't create any CO2, and recent research has improved the efficiency and lowered the cost of devices that achieve this. Now, engineers from Columbia University have developed a "solar fuels rig" that floats on the ocean, captures energy through a solar cell and uses it to harvest hydrogen from the water beneath it.
