A volume of gas may be too remote from a market for natural gas, making construction of a pipeline prohibitively expensive or in a region where demand for gas is saturated, and the cost of exporting gas beyond this region is excessive.

Economisers are mechanical devices intended to reduce energy consumption, or to perform useful function such as preheating a fluid.

Eco-sufficiency refers to the concept or strategy to reduce the environmental footprint of modern societies. As a goal, sufficiency is about ensuring that all humans can live a good life without overshooting the ecological limits of the Earth, while at the same time defining what that good life may consist of.

Eddy-current testing is one of many electromagnetic testing methods used in nondestructive testing (NDT) making use of electromagnetic induction to detect and characterize surface and sub-surface flaws in conductive materials.

The treatment of the edge before secondary surface preparation.

The shaping of a plate edge for welding. This may take the form of a V, X, Y, or K edge profile.

Cocoa butter, coconut oil, palm oil, peanut oil, rape oil, soya bean oil, sunflower oil. Most of edible oils have a specific gravity of 0.89t/m3.

The world's first coal-fired power station generating electricity for public use. It was built at number 57 Holborn Viaduct in central London, by Thomas Edison's Edison Electric Light Company.

The amount of heat energy received at any location on the globe is a direct effect of Sun angle on climate, as the angle at which sunlight strikes Earth varies by location, time of day, and season due to Earth's orbit around the Sun and Earth's rotation around its tilted axis.

The ability of the free-fall lifeboat to move away from the ship after free-fall launching without using its engine.

Effective dose is a dose quantity in the International Commission on Radiological Protection (ICRP) system of radiological protection.

A measurement of a resource’s ability to produce energy when the grid is most likely to experience electricity shortfalls.

Efficiency is the ability to avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result.

A patented semi-balanced rudder developed by Wärtsilä Corporation. The Efficiency Rudder is characterised by a streamlined “torpedo”-shaped bulb on the rudder hornimmediately abaft and coaxial with the propeller hub.

Efficient energy use, sometimes simply called energy efficiency, is the goal to reduce the amount of energy required to provide products and services and can also reduce effects of air pollution.

Waste or exhaust products from the combustion of fuels.

When testing the engine for NOx emissions, the reference fuel is Marine Diesel Oil (Distillate) and the test is performed according to ISO 8178 cycles.

A pump that has no moving parts or a mechanical driver. The pumping action is created as a pressurized fluid, referred to as the motive or operating fluid supplied from an external source, passes through the ejector.

Flying ships pioneered for military purposes in the 1930s by Russian aeronautical engineers. WIG craft flies just above sea level.
