This company has adopted advanced thermal-energy harvesting as a power source for its wireless products. Power Puck thermoelectric energy harvesters (photo) convert ambient heat commonly released in industrial processes into electricity for powering Rosemount wireless transmitters. Perpetua’s Power Puck energy-harvesting solution is especially advantageous to wireless devices in power-intensive applications, where a conventional power module may require replacements more frequently. The Power Puck thermoelectric energy harvester provides continuous, reliable power for the life of the transmitter and includes an intrinsically safe power module for backup power. — Emerson Process Management, Shakopee, Minn.
