Nextreme is actively applying Thermobility energy harvesting in the development of plumbing subsystems. Water in plumbing fixtures provides an excellent source of thermal energy for a variety of "green plumbing" applications.
Thermal energy from water supply lines under a sink and during flush valve operations can be converted to electricity as a source of power for LED status indicators, hands-free faucets, soap dispenser solenoids, and wireless transmitters for data acquisition applications. Harvested power can help reduce the size of batteries or eliminate them entirely depending on the application.
In addition, these subsystems can store energy and provide on-demand power while reducing the total cost of ownership by eliminating the prohibitive cost of battery replacement.
The plumbing subsystems are the latest additions to Nextreme's Thermobility™ energy harvesting platform that uses thin-film thermoelectric technology to convert available thermal energy into electric power for a variety of autonomous self-powered applications. Thermobility uses differences in temperature to enable 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, the Thermobility solution can provide electric power for years of maintenance-free operation, thus expanding the possibilities for new wireless sensor applications in plumbing, industrial control, transportation, automotive and building management.
