Small waterplane area twin hull (SWATH)

marine

A catamaran with unconventionally shaped hulls: two submarine-like floating bodies lie deep under the water surface and thus create the required buoyancy.

Small wind turbine

energy

Small wind turbines (wind turbine) also known as Micro Wind are used for microgeneration of electricity, as opposed to large commercial wind turbines, such as those found in wind farms, with greater individual power output.

Small, sealed, transportable, autonomous reactor

energy

Small, sealed, transportable, autonomous reactor (SSTAR) is a proposed lead-cooled nuclear reactor being primarily researched and developed in the United States. It is designed as a fast breeder reactor that is passively safe.

Small-scale wind power

energy

Small-scale wind power is the name given to wind generation systems with the capacity to produce up to 50 kW of electrical power.

Smart grid

energy

A smart grid is an electrical grid which includes a variety of operation and energy measures including an advanced metering infrastructure, smart distribution boards, home control and demand response.

Smart lighting

energy

Smart lighting is a lighting technology designed for energy efficiency, convenience and security.

Smart meters

energy

A smart meter is an electronic device that records information such as consumption of electric energy, voltage levels, current, and power factor

Smit bracket

marine

A fitting for securing the end link of a chafing chain, consisting of two parallel vertical plates mounted on a base with a sliding bolt passing through them.

Smog

marine

A mixture of pollutants, principally ground-level ozone, produced by chemical reactions in the air involving smog-forming chemicals.

Smoke

marine

Smoke can be black, blue, white, yellow or brown in colour. Black smoke is mainly comprised of carbon particulates (soot).

Smoke tube boilers

energy

A smoke tube boiler is one in which hot exhaust gas from the engine passes through tubes running within a sealed container of water.

SMPEP

marine

see Shipboard Marine Pollution Emergency Plan.

SNOX process

energy

SNOX process is a process which removes sulfur dioxide, nitrogen oxides and particulates from flue gases.

Social performance pillar

Society of Naval Architects and Marine Engineers (SNAME)

marine

An US based non-profit, technical organisation founded in 1893. SNAME is dedicated to promoting the art, science and practice of naval architecture, shipbuilding and marine engineering.

Sodar wind profiler

energy

a wind profiler that uses sound waves to measure wind speed at various heights above the ground, and the thermodynamic structure of the lower layer of the atmosphere.

Sodium-cooled fast reactor

energy

A sodium-cooled fast reactor is a fast neutron (generation IV) reactor cooled by liquid sodium.

Soft coating

marine

Coating which does not dry or which partially dries. It remains soft during its life time.

Soft energy path

energy

Analyst Amory Lovins coined the term soft energy path to describe an alternative future where energy efficiency and appropriate renewable energy sources steadily replace a centralized energy system based on fossil and nuclear fuels.
