Don’t look now, coppertop, but the Matrix has you. A company called Thermobility has unveiled a power generator for mobile devices that makes power from heat. The little device is aimed at low-power applications and is the size of a golf ball right now.
The device uses a heat sink with fins that gather heat and that heat is used to drive a Nextreme eTEG HV56 thermoelectric power generator. The maker says that the system is maintenance-free, and can run for decades with no interference.
The Thermobility WPG-1 generator can produce a constant voltage output of 3.3, 4.1, or 5.0 Vdc to electrical loads of 15kΩ and up. The WPG-1 is available for testing for $495. When we might see gear on the market using the tech is unknown.
