FTPS

FTPS, also called FTP Secure or FTP-SSL, is an extension of the File Transfer Protocol that adds TLS encryption and authentication, specified in RFC 4217 in October 2005.

FTU (tokamak)

FTU, or Frascati Tokamak Upgrade, was a compact, high-magnetic-field tokamak fusion experiment operated by ENEA at Frascati near Rome, with first plasma in 1990 and shutdown in 2019.

FTV (satellite series)

FTV, or Flight Test Vehicle, was the numbering scheme the US Air Force used to identify classified SAMOS reconnaissance satellites launched between 1962 and 1963.

Fu County power station

Fu County power station, also known as the Yanchang Petroleum Fuxian power plant, is a coal-fired station in Fu County, Yan'an, Shaanxi, China, with two 1,000 MW units operating since 2023.

Fu-Go balloon bomb

Fu-Go (fūsen bakudan) was a Japanese balloon bomb weapon of World War II; about 9,300 were launched from November 1944, causing six deaths at Bly, Oregon.

Fu‐Gen Wu

Fu-Gen Wu (吴富根, born 1983) is a Chinese biomedical engineer and full professor at Southeast University in Nanjing, known for work on polyphenol-containing nanoparticles and hydrogel-based drug delivery.

Fudong Han

Fudong Han is a battery and electrochemistry researcher and associate professor at Rensselaer Polytechnic Institute, known for showing that electronic conductivity in solid electrolytes causes lithium dendrite formation.

Fuel

A fuel is a material whose stored chemical energy is released as heat by combustion, powering buildings, electricity generation, and nearly all transport; examples include gasoline, natural gas, coal, biofuels, and hydrogen.

Fuel assembly

A fuel assembly is the bundle of sealed fuel rods, spacer grids, and guide tubes that forms the basic replaceable unit of fuel in a nuclear reactor core.

Fuel cell

A fuel cell is an electrochemical device that converts fuel, typically hydrogen, directly into electricity, producing water and heat; unlike a battery, it works as long as fuel is supplied.

Fuel cell cold start

Fuel cell cold start is the startup of a proton exchange membrane fuel cell from subfreezing temperatures, where product water can freeze inside the cell and block its operation.

Fuel cell range extender

A fuel cell range extender is a small hydrogen fuel cell, typically 30 to 80 kW, added to a battery-electric vehicle to recharge its battery and extend its driving range.

Fuel cell vehicle

A fuel cell vehicle, or fuel cell electric vehicle (FCEV), is an electric vehicle that makes its own electricity onboard from hydrogen, emitting only water vapor.

Fuel Cells and Hydrogen Joint Undertaking

The Fuel Cells and Hydrogen Joint Undertaking (FCH JU) was a Brussels-based public-private partnership of the European Union, industry, and research groups that funded hydrogen and fuel cell technologies from 2008.

Fuel cladding

Fuel cladding is the thin-walled metal tube that seals nuclear fuel pellets in a fuel rod, preventing corrosion and fission product release; zirconium alloys are standard in light-water reactors.

fuel cost adjustment charge

A fuel cost adjustment charge is a line item on electricity bills that raises or lowers the per-kWh price to track the utility's actual fuel and purchased power costs, usually without profit.

Fuel Direct

Fuel Direct is the informal UK scheme for deducting gas and electricity debts directly from social security benefits, dating to 1980, with around 100,000 arrangements in April 2022.

Fuel dumping

Fuel dumping, also called fuel jettison or fuel dump, is the airborne release of unused fuel from an aircraft to reduce its weight enough to land safely.

Fuel economy in aircraft

Fuel economy in aircraft measures how much fuel an airplane burns to carry a payload a given distance, driven by engine efficiency, lift-to-drag ratio, and weight; jet fuel use doubled in efficiency from 1960 to 2008.

Fuel economy in automobiles

Fuel economy in automobiles is the distance a vehicle travels per unit of fuel, measured as miles per gallon in the US and liters per 100 km elsewhere.

Fuel efficiency

Fuel efficiency, also called gas mileage or fuel economics, is a measure of useful output per unit of fuel, commonly expressed for vehicles as miles per gallon.

Fuel hedging

Fuel hedging is the practice of using financial instruments like swaps and options to lock in fuel prices in advance, used most prominently by airlines, for whom fuel is a leading operating cost.

Fuel injection

Fuel injection is the delivery of fuel into an internal combustion engine under pressure instead of by a carburetor, with modern systems controlled by an electronic unit.

Fuel oil

Fuel oil is any liquid petroleum product made from crude oil and refined or blended to burn in engines, furnaces, boilers, and heaters, or as a solvent.

Fuel performance modeling

Fuel performance modeling is the computational simulation of nuclear fuel rod behavior in a reactor, and utilities and regulators use its predictions for safety analyses and licensing.

Fuel poverty

Fuel poverty is a household's inability to keep its home warm at reasonable cost, arising from low income, high energy prices, and an energy-inefficient dwelling; the term is used mainly in the UK and Ireland.

Fuel Price Stabilization Fund

The Fuel Price Stabilization Fund (Spanish: Fondo de Estabilización de Precios de los Combustibles) is Colombia's mechanism for smoothing domestic gasoline and diesel prices, created in 2007.

Fuel pump

A fuel pump is a device that moves fuel from a vehicle's tank to its engine at the pressure and volume the fuel system requires.

Fuel rod

A fuel rod is a long, slender tube, generally made of a zirconium alloy, holding stacked fissionable pellets and serving as the basic fuel element of a nuclear reactor.

Fuel surcharge

A fuel surcharge, also called a YQ or carrier-imposed surcharge, is an extra fee airlines add to fares and award tickets to recover fuel costs.
