An MIT device able to harvest energy from temperature fluctuations could provide power for devices in remote places.
The thermal resonator generates electricity from the changes in ambient temperature during the day and night cycle. Optimized for thermal effusivity, the device includes a phase-change material that stores heat and graphene that provides quick conduction when it is time to covert the heat to electricity. According to the MIT team, the thermal resonator does not require sunlight and is not very affected by wind conditions, allowing it to continuously generate power for sensors in remote or hard to reach areas.
