Following on from the previous post, we have another article from the BBC on innovative ways to harvest power from activities people already carry out. This one is all about utilizing a potentially huge source of energy – children. As mothers everywhere will attest, kids can sometimes seem to run around all day, with no specific aim, and all this energy can now help charge electrical cells (batteries), to power lights etc. into the evening, where villages aren’t on a power grid already. Obviously remote locations in Africa where what the inventor had in mind, but the uses could well spread far and wide – in terms of eco-friendly power, you could create systems to light up childrens play areas in the west, without relying on conventional electricity systems, which involve burning fossil fuels, or nuclear power.
