Some Penn State researchers are taking a cue from nature and have built the first solar cell that can effectively split water to harvest the hydrogen. While the technology and efficiency of electricity-gathering solar cells has been humming on nicely, cells that can pull hydrogen out of water directly (instead of using solar-harvested electricity to do it) have found that the catalysts conducive to separating hydrogen and oxygen are usually pretty good at putting the two gases right back together again. The folks at Penn State have now developed a process that more closely mimics the photosynthesis proce
