Devices known as optical rectennas show considerable promise for renewable energy because they can harvest energy from heat and convert it into electricity. Rectennas (short for rectifying antennas) consist of two parts: an antenna, which absorbs electromagnetic radiation, and a diode, which converts the absorbed energy into direct current.
