These Boots Are Made For Energy Generation

A small company has produced a boot that creates energy by walking. The boot has a battery that stores an electric charge from the energy spent by walking.

The ‘Power Wellies’, as Orange is calling them, convert heat from your feet into an electrical current. According to the blurb, twelve hours of stomping through the Glastonbury Festival will give you enough power to charge a mobile phone for one hour – the hotter your feet get, the more energy you produce.

In case you’re wandering what the science behind them is… Inside the power generating sole there are thermoelectric modules constructed of pairs of p-type and n-type semiconductor materials forming a thermocouple. These thermocouples are connected electrically forming an array of multiple thermocouples (thermopile). They are then sandwiched between two thin ceramic wafers. When the heat from the foot is applied on the top side of the ceramic wafer and cold is applied on the opposite side, from the cold of the ground, electricity is generated. Simples.

  1. So do these soles feel cooler than a normal sole would? Seems like they should, but then, seems like that would be a free lunch. I guess, the colder they feel, the less efficient they are operating.
