Heat from our bodies could generate green energy

If you’ve ever seen yourself through a thermal imaging camera, you’ll know that your body produces lots of heat. This is in fact a waste product of our metabolism. Every square foot of the human body gives off heat equivalent to about 19 matches per hour.

Unfortunately, much of this heat simply escapes into the atmosphere. Wouldn’t it be great if we could harness it to produce energy? My research has shown this would indeed be possible. My colleagues and I are discovering ways of capturing and storing body heat for energy generation, using eco-friendly materials.

The goal is to create a device that can both generate and store energy, acting like a built-in power bank for wearable tech. This could allow devices such as smart watches, fitness trackers, or GPS trackers to run much longer, or even indefinitely, by harnessing our body heat.
