The Future is Here: The Artificial Leaf
Oft I have been perplexed by the energy crisis that is going to hit us. Oft I have dreamt of a device to produce oxygen from water. In my most stimulating episodes of daydreaming, I used to dream of a large factory which would be equipped with genetically engineered micro-organisms. These little machines would be cultivated in large scale to produce oxygen from water. But I was not satisfied. I did not day dream about chemical equations. I was not aware of technological advances which would make it possible to create oxygen from water without having to be plugged into an energy source. My aims were inclined to oxygen production and clean energy. The concept of biodiesel enthused me for a short period of time. But here again, I could not figure out its economic and practical viability. With a global crisis of agricultural land and food production demands outweighing supply I was hard pressed to think out an innovative way of biodiesel production. I thought of ‘vertical plantation’...
