Adam Grosser is a genius. With all of the people (1.6 billion, in fact) that do not have access to electricity, disease is a HUGE problem – first of all, because they cannot refrigerate food, so disease is spread quickly; and second of all, because they cannot refrigerate medicine to cure disease. Grosser and his team have figured out a way to produce cheap, non-toxic, electricity-free refrigerators, and they have no doubt that they will be entirely capable of distributing them to the parts of the world that need them the most. I’ll let him explain it to you, though, seeing as I am REALLY not a science person … incredible! Eco-revolution, indeed!
