So there is a lot of science here. Take your time and break down the terms into simpler forms. It's an article about transforming carbon monoxide into oxygen in a practical sense. Taking photosynthesis, natures' most efficient and effective process, and reversing it. Did anyone else ever learn about this? The idea hadn't ever crossed my head as a possibility. Granted I'm far from a scientist, but the concept is scarily simple. Apparently the science just isn't capable yet. Trillions of layered gold and copper molecules need to be arranged in such a way that a "tree" is created. Once the easy part of artificial tree creation is wrapped up, because we all know trees are simple at the molecular level, a catalyst needs to be found. This catalyst will provoke the trees into absorbing the carbon and releasing the oxygen. Plants use the powerful sun to begin their photosynthesis, an almost endless and ever powerful source of energy. Gold and copper are the best conductors known to man, and a massive electric current could "spark" our man made trees into creating this reaction. To say it simply we can use this groundbreaking research to reverse the green house effect. If implemented in a large enough scale we could save our planet from the unsustainable damage we are doing to it at an exponential rate. Electricity at this point isn't a reliable enough catalyst. Naturally it rarely happens on a grand enough scale, no place on earth has endless lightening storms. The resources it would take to produce such large quantities of electricity [plants use the sun which is light years away, but still gives enough energy to make things grow] would kill every benefit behind this entire idea. The foundation has been set, who's going to pave the way? Nanotechnological trees seems to be the key, with the biproduct of this reverse photosynthetic oxygen creation being the energy they use to "survive"
