When we walk, heat energy will be produced. The solar cells underneath the shoes will take in the heat energy and stored the energy into the solar cells. The solar cells which are connected to the user’s bag by a series of wires will be changed into electrical energy to charge any electrical devises in the bag. So we will not have to worry about batteries being flat because we have a portable ‘electrical charger’!!!!!!
