As kids, you might have spent many afternoons, under a huge tree, enjoying its shade. In a tropical country like India, trees are a welcome sight in the month of May, when the sun is blazing in the sky and the shade offered by them is a hundred thousand times better than artificial cooling of the air conditioning units. But never in our dream would we have thought that the rustling of the tiny leaves of the trees could one day make electricity for us.Because that requires a Hendersonian moment! (just in a bit)

This brilliant idea has come from the lab of a biophysicist at Iowa State University, Dr. Michael McCloskey, whose work at the University largely involves the study of membrane transport in algae and adult born neurons but also has a background in plant sciences. It was his colleague in the department of genetics, Dr. Eric Henderson who first came up with this plan of harvesting energy from leaves as he wondered how much kinetic energy was being generated when winds blow across l…
