Sep 2011: Marlow Industries has announced, "a complete range of thermoelectric-based energy harvesting devices, offering customers a low-cost, zero-maintenance power solution for wireless sensor applications…By converting small degrees of temperature difference into milliwatts of electrical power [they] can perpetually power wireless sensors for the lifetime of the application. This green innovation offers a solid-state, reliable energy source for sensors, actuators, valve solenoids and other small devices by recycling wasted heat…With new building codes requiring sophisticated lighting, heating, ventilation and air-conditioning systems (HVAC), 'smart' designs are key to moderating usage…builders will have a cost-effective and green alternative that will relieve resources spent powering these devices."
