the most fuel-efficient airline was norwegian air shuttle with 44 pax-km/l 2.27 l/100 km 104 mpg ‑us per passenger , thanks to its fuel-efficient boeing 787-8, a high 85% passenger load factor and a high density of 1.36 seat/m 2 due to a low 9% seven trust seating.
energy-efficient driving techniques are used by drivers who wish to reduce their fuel consumption, and thus maximize fuel efficiency.the use of these techniques is called 'hypermiling'.simple fuel-efficiency techniques can result in reduction in fuel consumption without resorting to radical fuel-saving techniques that can be unlawful and dangerous, such as tailgating larger vehicles.
the fuel economy of an automobile relates distance traveled by a vehicle and the amount of fuel consumed. consumption can be expressed in terms of volume of fuel to travel a distance, or the distance travelled per unit volume of fuel consumed. since fuel consumption of vehicles is a significant factor in air pollution, and since importation of motor fuel can be a large part of a nation's .
fuel channels - 312 channels. each one is 1.1 in. id, 23.5 in. long and holds up to 4 fuel elements. fuel element - 1 in. od, 0.5 in. id and 5.5 in. long 25.4 mm x 12.7 mm x 139.7 mm . core power density - 1.3 w/cc; fuel utilization - up to 50%. coolant - helium at 500 psi 3.45 mpa
the multimachine is an all-purpose open source machine tool that can be built inexpensively by a semi-skilled mechanic with common hand tools, from discarded car and truck parts, using only commonly available hand tools and no electricity. its size can range from being small enough to fit in a closet to one hundred times that size. the multimachine can accurately perform all the functions of .
solid fuel sonoluminescence – the emission of short bursts of light from imploding bubbles in a liquid when excited by sound. sstar – small, sealed, transportable, autonomous reactor
fuel saving devices are sold on the aftermarket with claims to improve the fuel economy and/or the exhaust emissions of any purport to optimize ignition, air flow, or fuel flow in some way. an early example of such a device sold with difficult-to-justify claims is the 200 mpg ‑us 1.2 l/100 km carburetor designed by canadian inventor charles nelson pogue.
a traveling-wave reactor twr is a proposed type of nuclear fission reactor that can convert fertile material into usable fuel through nuclear transmutation, in tandem with the burnup of fissile material.twrs differ from other kinds of fast-neutron and breeder reactors in their ability to use fuel efficiently without uranium enrichment or reprocessing, instead directly using depleted uranium .
jet fuel, aviation turbine fuel atf , or avtur, is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines.it is colorless to st-colored in appearance. the most commonly used fuels for commercial aviation are jet a and jet a-1, which are produced to a standardized international specification.

the molten-salt reactor experiment msre was an experimental molten salt reactor at the oak ridge national laboratory ornl researching this technology through the 1960s; constructed by 1964, it went critical in 1965 and was operated until 1969.. the msre was a 7.4 mw th test reactor simulating the neutronic 'kernel' of a type of inherently safer epithermal thorium breeder reactor called the .
crankcase-compression two-stroke engines, such as common small gasoline-powered engines, are lubricated by a petroil mixture in a total-loss system. oil is mixed in with their petrol fuel beforehand, in a ratio of around 1:50. this oil then forms emissions, either by being burned in the engine or as droplets in the exhaust, resulting in more .
brazil has the largest and most successful bio-fuel programs in the world, involving production of ethanol fuel from sugarcane, and it is considered to have the world's first sustainable biofuels economy. in 2006 brazilian ethanol provided 18% of the country's road transport sector fuel consumption needs, and by april 2008, more than 50% of fuel consumption for the gasoline market.
still, many customers of large-scale flywheel energy-storage systems prefer to have them embedded in the ground to halt any material that might escape the containment vessel. energy storage efficiency. flywheel energy storage systems using mechanical bearings can lose 20% to 50% of their energy in two hours.
common rail direct fuel injection is a direct fuel injection system for diesel engines.. it features a high-pressure over 2,000 bar or 200 mpa or 29,000 psi fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors or pump nozzles .third-generation common rail diesels now feature piezoelectric injectors for increased precision, with fuel pressures up .
