A centrifuge is a device that uses centrifugal force to separate various components of a fluid.

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow.

A centrifugal governor is a specific type of governor with a feedback system that controls the speed of an engine by regulating the flow of fuel or working fluid, so as to maintain a near-constant speed.

Centrifugal force is an inertial force that appears to act on all objects when viewed in a rotating frame of reference.

Flow centers located centrally in a ground source system that produce flow to all heat pump units in that system.

Central heating is used to heat many connected areas such as the rooms of a house.

A variant of the metric system based on the centimetre as the unit of length, the gram as the unit of mass, and the second as the unit of time.

The degree Celsius (°C) is a unit of temperature on the Celsius scale, a temperature scale originally known as the centigrade scale.

Cellulosic ethanol is ethanol (ethyl alcohol) produced from cellulose (the stringy fiber of a plant) rather than from the plant's seeds or fruit.

A ceilometer is a device that uses a laser or other light source to determine the height of a cloud ceiling or cloud base.

Cavitation is a phenomenon in which the static pressure of the liquid reduces to below the liquid's vapour pressure, leading to the formation of small vapor-filled cavities in the liquid.

A method of thermal energy storage where unused mines and purpose built caverns can be used for thermal energy storage. To be economical they need to be close to industrial or community areas.

Cathodic protection is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode.

A cathode is an electrode through which conventional current leaves an electrical device.

An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric trains, trolleybuses or trams.

A catalytic cycle is a multistep reaction mechanism that involves a catalyst.

Catalysis is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst.
