The adaptive temperature controller includes a device for measuring resistance, an electrically-conductive material, a power supply, and a device for controlling power. In operation, the controller determines the resistance of material at one or more temperatures and therefore determines the resistance of the material through a range of operating temperature. Based on such determination so long as voltage and power are known, the resistance of the material, and therefore its temperature, are known. As a result the voltage or power may be instantly varied to produce near infinite control over material temperature.
