Netherrack Thermocoupling

Netherrack Thermocouplings were a component of the TARDIS.

While remembering instructions from her Type 40 Operational Handbook, Christel Dee disabled the etheric beam locator, shield oscillator, and the food machine, then diverted "all the power" to the temporal Glowstone stabilisers and the Netherrack Thermocouplings, before declaring "yes!" and landing.
