Heat Inverse LLC is developing thin-film materials that get cold with no energy input and no waste heat generated. The company's products include air sealed cooling systems with air-tight, moisture-tight electronics enclosures thermally coupled to the surrounding air that maintains content at a constant temperature, within 0.5 degree C and wireless temperature sensor networks that comes with 5V 1A power supply and can be connected to wifi, and use only 1/2watt, enabling manufacturers to increase efficiency simply and inexpensively, using thin-film materials that get cold with zero-energy input.
