In my daily news reading on the internets I always pay special attention to green and alternative energy stories. This is probably partly because of the project we are doing (Minerva likes green energy), but also because my dad has almost always worked in nuclear power, so I’ve been thinking about electricity sources for a long time 
One of my most recent posts was about harnessing a plant-microbe fuel cell. Today, I want to talk about projects that work to harvest the energy potential of play.
