A gas turbine, also called a combustion turbine, is a type of continuous and internal combustion engine. The main elements common to all gas turbine engines are:
A tugboat or tug is a type of vessel that maneuvers other vessels by pushing or pulling them either by direct contact or by means of a tow line. Tugs typically move vessels that either are restricted in their ability to maneuver on their own, such as ships in a crowded harbor or a narrow canal, or those that cannot move by themselves, such as barges, disabled ships, log rafts, or oil platforms. Tugboats are powerful for their size and strongly built, and some are ocean-going. Some tugboats serve as icebreakers or salvage boats. Early tugboats had steam engines, but today most have diesel engines. Many tugboats have firefighting monitors, allowing them to assist in firefighting, especially in harbors.
Green building refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from planning to design, construction, operation, maintenance, renovation, and demolition. This requires close cooperation of the contractor, the architects, the engineers, and the client at all project stages. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort.
A green vehicle, or clean vehicle, or eco-friendly vehicle or environmentally friendly vehicle is a road motor vehicle that produces less harmful impacts to the environment than comparable conventional internal combustion engine vehicles running on gasoline or diesel, or one that uses certain alternative fuels. Presently, in some countries the term is used for any vehicle complying or surpassing the more stringent European emission standards, or California's zero-emissions vehicle standards, or the low-carbon fuel standards enacted in several countries.
The Monroney sticker or window sticker is a label required in the United States to be displayed in all new automobiles and includes the listing of certain official information about the car. The window sticker was named after Almer Stillwell "Mike" Monroney, United States Senator from Oklahoma. Monroney sponsored the Automobile Information Disclosure Act of 1958, which mandated the disclosure of equipment and pricing information on new automobiles.

Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or engine turning a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems.
The Future Launchers Preparatory Programme (FLPP) is a technology development and maturation programme of the European Space Agency (ESA). It develops technologies for the application in future European launch vehicles (launchers) and in upgrades to existing launch vehicles. By this it helps to reduce time, risk and cost of launcher development programmes.
Started in 2004, the programmes initial objective was to develop technologies for the Next Generation Launcher (NGL) to follow Ariane 5. With the inception of the Ariane 6 project, the focus of FLPP was shifted to a general development of new technologies for European launchers.
FLPP develops and matures technologies that are deemed promising for future application but currently do not have a sufficiently high technology readiness level (TRL) to allow a clear assessment of their performance and associated risk. Those technologies typically have an initial TRL of 3 or lower. The objective is to raise the TRL up to about 6, thus creating solutions which are proven under relevant conditions and can be integrated into development programmes with reduced cost and limited risk.
Efficient energy use, sometimes simply called energy efficiency, is the goal to reduce the amount of energy required to provide products and services. For example, insulating a home allows a building to use less heating and cooling energy to achieve and maintain a comfortable temperature. Installing LED lighting, fluorescent lighting, or natural skylight windows reduces the amount of energy required to attain the same level of illumination compared to using traditional incandescent light bulbs. Improvements in energy efficiency are generally achieved by adopting a more efficient technology or production process or by application of commonly accepted methods to reduce energy losses.
An LNG carrier is a tank ship designed for transporting liquefied natural gas (LNG). As the LNG market grows rapidly, the fleet of LNG carriers continues to experience tremendous growth.
Luna is a historic tugboat normally berthed in Boston Harbor, Massachusetts. Luna was designed in 1930 by John G. Alden and built by M.M. Davis and Bethlehem Steel. She is listed on the National Register of Historic Places and is a U.S. National Historic Landmark. In 1985, the Luna was designated as a Boston Landmark by the Boston Landmarks Commission.
A ducted propeller, also known as a Kort nozzle, is a marine propeller fitted with a non-rotating nozzle. It is used to improve the efficiency of the propeller and is especially used on heavily loaded propellers or propellers with limited diameter. It was developed first by Luigi Stipa (1931) and later by Ludwig Kort (1934). The Kort nozzle is a shrouded propeller assembly for marine propulsion. The cross-section of the shroud has the form of a foil, and the shroud can offer hydrodynamic advantages over bare propellers, under certain conditions.
Foss Maritime is an American shipping company. The company was founded in 1889 by Thea Foss (1857–1927) and her husband Andrew Foss. The company is now the largest tug and towing concern on the west coast of the United States.
The Clean Sky Joint Undertaking (CSJU) is a public-private partnership between the European Commission and the European aeronautics industry that coordinates and funds research activities to deliver significantly quieter and more environmentally friendly aircraft. The CSJU manages the Clean Sky Programme (CS) and the Clean Sky 2 Programme (CS2), making it Europe’s foremost aeronautical research body.
Fuel economy in aircraft is a measure of how much fuel an aircraft, or a fleet of aircraft of mixed types, needs to operate in relation to a service provided and the distance between points of travel. It can be expressed in several ways, for example by the liters of fuel consumed per passenger per kilometer.
BB 63413 PLATHEE is a hybrid locomotive that was used for testing on the French rail operator SNCF. PLATHEE is an acronym for "Platform for Energy- Efficient and Environmentally Friendly Hybrid Trains".
Sause Bros., Inc., a pioneering Oregon ocean towing company founded in 1936, is a privately held, fourth-generation family company serving routes along the West Coast of the United States, Hawaii and other islands of the South Pacific, as well as Alaska.

Miscaroo was an icebreaking anchor handling tug supply vessel built by Vancouver Shipyards for BeauDril, the drilling subsidiary of Gulf Canada Resources, in 1983. She was part of a fleet of Canadian icebreakers used to support offshore oil exploration in the Beaufort Sea. In the 1990s, the vessel was acquired by Canadian Marine Drilling (Canmar) and renamed Canmar Miscaroo. In 1998, she was purchased by Smit International and served in the Sakhalin oil fields as Smit Sakhalin until 2017 when the 34-year-old icebreaker was sold for scrapping in China.

She was part of a fleet of Canadian icebreakers used to support offshore oil exploration in the Beaufort Sea. In the 1990s, the vessel was acquired by Canadian Marine Drilling (Canmar) and renamed Canmar Ikaluk. In 1998, she was purchased by Smit International and served in the Sakhalin oil fields as Smit Sibu. Since 2009, she was owned by FEMCO Management and in 2012 was given back her original name. Ikaluk was sold to China in February 2018 and later renamed Beijing Ocean Leader.
