Marine toilet, ship toilet - designed to receive, retain & discharge sewage. Gravity or vacuum technology is used to drive waste from toilet bowl into treatment tank.
Reverse osmosis (RO) freshwater makers are technical solutions that convert seawater, well or effluent (polluted industrial water) into freshwater or 'permeate'.
The phenomenon where a gas or liquid changes temperature when it experiences a pressure drop.
Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing impurities, contaminants and higher molecular mass hydrocarbons to produce what is known as pipeline quality dry natural gas.
Shale gas is natural gas trapped in fine-grained sedimentary rock, particularly quartz and calcite.
A technology that uses electrical power to produce a gaseous fuel.
Power to gas is a technology which converts electrical power to a gas fuel.
A polytunnel is a tunnel typically made from steel and covered in polyethylene, usually semi-circular, square or elongated in shape. The interior heats up because incoming solar radiation from the sun warms plants, soil, and other things inside the building faster than heat can escape the structure.
These collectors are an alternative to metal collectors and are now being produced in Europe.
A type of fuel cell being developed mainly for transport applications, as well as for stationary and portable fuel-cell applications.
Pollution is the introduction of contaminants into the natural environment that cause adverse change.
Polarity symbols are a notation for electrical polarity, found on devices that use direct current (DC) power, when this is or may be provided from an alternating current (AC) source via an AC adapter.
The polar climate regions are characterized by a lack of warm summers.
The point in the electric circuit where a microgrid is connected to a main grid.
This device floats on the surface of the water, held in place by cables connected to the seabed.
Pneumatics is a branch of engineering that makes use of gas or pressurized air.
A pneumatic motor (air motor), or compressed air engine, is a type of motor which does mechanical work by expanding compressed air.
Plutonium-239 is also one of the three main isotopes demonstrated usable as fuel in thermal spectrum nuclear reactors, along with uranium-235 and uranium-233.
Plutonium-238 (238Pu) is a radioactive isotope of plutonium that has a half-life of 87.7 years. Plutonium-238 is a very powerful alpha emitter; as alpha particles are easily blocked, this makes the plutonium-238 isotope suitable for usage in radioisotope thermoelectric generators (RTGs) and radioisotope heater units.
The agreement regulates the conversion of non-essential plutonium into mixed oxide (MOX) fuel used to produce electricity.
