Brazillian designer, João Lammoglia has come up with a couple of renewable energy sources that we hadn’t thought of:
- The Aire converts the energy of the user’s breathing into electrical energy. Inside the device, small wind turbines produce the electricity which is transferred through a cable to charge a electronic device.
- The Doormate converts the energy supplied by the user wiping their feet to power an electric doorbell. To enhance the efficiency of the system, the wooden door is used as a sound amplifier.
