In the past, we typically only thought of the term “harvesting” in relation to agriculture. Perhaps that was a simpler time, before Big Data allowed us to “harvest” great insights for example. At its root (pun intended), harvesting is all about gathering something of value. That something is almost limitless: corn, vibrations, wheat, wasted heat, tomatoes, phone records, fish, etc. More and more, people are looking towards harvesting various forms of energy to improve lives, both present and future, human and battery. As we continually strive to increase energy efficiency and reduce waste, a wide variety of energy conversion and energy harvesting techniques are being explored and developed. Unlike traditional energy generation, which usually requires inputs that cost money (oil, coal, natural gas), energy harvesting generates usable electricity with “free” energy sources already present in the operating environment.
