MIT engineers built a device that generates electricity from the air

Temperature changes are taking place around us all the time, and scientists have created a device that can convert these fluctuations into electricity by feeding sensors and communication devices with the help of the surrounding air. The energy is obtained by what is called a thermal resonator: a device that captures the heat on one side and emits it on the other. As both sides try and achieve balance, energy can be generated using the...
