Thermobility™ power generation technology from Nextreme Thermal Solutions (Durham, NC) uses heat as a source of electricity for low-power wireless applications. Solid-state thin-film thermoelectric technology is used to convert heat into electricity for a variety of self-contained, autonomous systems. This solution enables “wireless power” anywhere there is an adequate heat source and eliminates the need to use traditional wired power sources or replaceable batteries. When paired with wireless transmitters, it can provide electric power for decades of maintenance-free operation. The Thermobilitiy WPG-1 provides a constant voltage output of 3.3, 4.1, or 5.0 Vdc to electrical loads of 15 kW or higher. The integrated circuit board includes DIP switches for setting the output voltage.
