Australian engineers have proved the hypothesis by generating electricity using night-vision goggles.
With current photovoltaic technology, it may harvest the modest amount of energy generated by solar cells cooling after a long, hot day's labour.
Infrared energy from a warm Earth is diverted into the frigid Universe by chemoradiation.
By heating atoms, you force their electrons to emit low-energy infrared light.
Mercury cadmium telluride makes up the diode (MCT). MCT is used to absorb mid-and long-range infrared light and transform it into a current.
