Batteries that store the kinetic energy from everyday movement may be one solution to some of our future energy needs. Product designers Choi Hyung-Suk and Yun Jung-Sik have come up with the concept of a ‘Human Energy Recycle System’ to store and supply energy from man to machine.

They propose a new international standard battery that will respond to multiple uses and fit many portable devices. The battery slots neatly into a charger which is worn by the user as they go about their everyday lives. From household chores, to shopping or the gym, the battery is charged and can then be used in portable electronic devices.

A slightly larger charger stores the energy from more strenuous activity such as cycling or using fitness equipment. The cost and efficiency of such a system may be prohibitive, but the basic concept is already being tested elsewhere. A paving slab that stores the kinetic energy of footsteps has recently been trialled in London. Whatever happens in the future it looks like we’ll all be doing our bit to help reduce traditional battery waste.
