The global aircraft fuel systems market is expected to reach USD 9.15 Billion by 2020 from USD 6.52 Billion in 2015, at a CAGR of 7.0% during the forecast period. An aircraft fuel system pumps fuel from fuel tank into the aircraft engine.

Wind is one important source of alternative energy. In this activity, kids create their own wind turbine and attach it to a Hot Wheels Car. Then they can use a fan to power the turbines so their cars can move! Wind is a great alternate to fuel since fuel pollutes the air and is nonrenewable. Because wind is a renewable energy source, we will never run out! However, as the girls at Girlstart discovered from testing their own cars, there are some cons to powering a car with wind.

"Designing an airplane isn't easy. You have to know aerodynamics, physics, and how to balance lift, drag, and engine fuel efficiency so that they all work together. No, designing an airplane isn't easy at all. Unless you have our little design application, then it's a walk in the park."

"The Earth's climate is a solar powered system. Globally, over the course of the year, the Earth system-land surfaces, oceans, and atmosphere-absorbs an average of about 240 watts of solar power per square meter (one watt is one joule of energy every second). The absorbed sunlight drives photosynthesis, fuels evaporation, melts snow and ice, and warms the Earth system."

"The gigantic dimensions of this ultra-lightweight revolutionary airplane - capable of flying day and night without fuel - are its trademark feature. To build it, the whole team had to push back the frontiers of knowledge in materials science, energy management and the man-machine interface. Every one of its take-offs, propelled silently by its four electric motors, inspires us to consider using clean, new technologies to free our society, little by little, from dependence on fossil energy. "

"The most important gas which leads to acidification is sulfur dioxide. Emissions of nitrogen oxides which are oxidized to form nitric acid are of increasing importance due to stricter controls on emissions of sulfur containing compounds. 70 Tg(S) per year in the form of SO2 comes from fossil fuel combustion and industry, 2.8 Tg(S) from wildfires and 7-8 Tg(S) per year from volcanoes.[24]"

"Being in space is not at all like being on Earth. It's usually very hot or very cold. There's no air. There's very little gravity. And the radiation is terrible! Suppose you are a very smart spacecraft engineer. You have invented a new material to use for the fuel tanks on the spacecraft. But before you send your new material into the harsh environment of space, you must test it on Earth in a space-like situation. "

Wastepoered Toilet Mobile - An innovative hybrid project is turning heads across Japan, as the TOTO Bike Neo, known more causally as the poop-mobile, makes a high-profile pitch for environmental responsibility. The three-wheeled bike is powered by biogas fuel made up of fertilized, purified livestock waste and gray-water, according to the International Business Times. Despite the eye-catching -- and decorative -- oversized-toilet seat, the bike does not actually run on excrement provided by the driver. "

" At about 31 million flights per year, aviation is the fastest-growing fossil fuel-burning sector in today's global economy, and emissions are expected to increase significantly in the next few decades, while other sectors decrease."

"With each of their great achievements, the adventurers of the last century constantly pushed back the limits of the impossible. Today, the drive to make new discoveries must go on, not to conquer new territories but with the aim of improving the quality of life on our planet. In building the first solar aircraft able to fly day and night, and piloting it right round the world without fuel or pollution, Solar Impulse's ambition is for the world of exploration and innovation to contribute to the cause of renewable energies, to demonstrate the importance of clean technologies for sustainable development; to save natural resources and reduce our dependency on fossil energy; and to place dreams and emotions back at the heart of scientific adventure."

Engineered Sports - TryEngineering - Lesson focuses on how the principles of aerospace engineering have impacted golf ball design, along with equipment used in other sports. Students analyze the use of dimples on golf balls, and work as a team of engineers to determine whether adding dimples to airplanes would increase fuel efficiency for the airline industry.

research and design a large passenger aircraft that is less noisy, less harmful to the environment, and more fuel-efficient than current models

On December 23, 1986, "Voyager" completed the first nonstop, non-refueled flight around the world. A unique aircraft constructed almost entirely of lightweight graphite-honeycomb composite materials and laden with fuel, "Voyager" lifted off from Edwards Air Force Base, California, at 8:01 a.m. on December 14, 1986. It returned nine days later at 8:05 a.m.

The Bo 105 is a light twin engine multi purpose utility helicopter built by Messerschmitt-Bölkow-Blohm (MBB) of Stuttgart, Germany. As the first light twin-engine helicopter in commercial service, it gained widespread use over rural areas (police and EMS / medevac) as well as offshore. The four-blade hingeless main rotor with composite blades ensures high maneuverability. All main systems (hydraulics, electric, fuel, lubrication) were designed to be fully redundant. "

Photo #7. Max Leslie ditching. Because LCDR Leslie's SDB was out of fuel the aircraft floated. Leslie and his gunner walked out to the end of the wing and stepped into the whaleboat sent to rescue them. THEY DIDN'T EVEN GET THEIR FEET WET.
