At London's Heathrow, which moves more international passengers than any other airport, the fuel jockeys of the Aircraft Service International Group oversee refueling. Filling an Airbus A380 can take two hours, at a rate of about 1,000 gallons per minute.

It’s been nearly a full month since the Costa Concordia ran aground just off the Tuscan island of Giglio, and after two weeks of delays salvage workers yesterday began pumping operations aimed at recovering most of the half million gallons of fuel aboard the badly listing Italian cruise liner. Roughly 84 percent of that fuel is stuck in 15 large tanks, and pumping that volume out of the ship will likely take another month--and that’s with the pumps running around the clock.
Our dependence on big systems--big oil, big coal--steers us away from little ones, such as biofuel made from garbage, that are transforming communities in other countries

From the backseat of a beat-up Toyota taxi, Thomas Taha Rassam Culhane points out the passing sights. Fraying sacks of charcoal cut from nearby forests wait beside makeshift shops. Corrugated metal, cardboard and other scrap make up the ramshackle huts. A stream of dirty water, stained red by runoff from a nearby factory, runs down the alley. Garbage is everywhere. The ingredients of life here in Mukuru, one of Nairobi's largest slums, are raw. Yet Culhane leans forward in his seat, excited by the possibilities they present.
The taxi stops at the Mukuru Skills Training Center, an art and vocational school. A guard emerges from a small concrete shack to open the front gate. The Mukuru neighborhood is dirty and chaotic, but inside the compound, tidy bits of improvisation are everywhere: An art studio opens onto a small garden filled with herbs and saplings. Three composting toilets turn waste into fertilizer. And outside a bare-bones kitchen, a 500-gallon tank full of old beans and banana peels is slowly generating cooking gas.
When a satellite runs out of fuel, there are really only a couple options: Quietly become a piece of space junk, or fall back to Earth in a blaze of glory. But a new space gas station will fill ‘em up, ensuring satellites can keep on trucking and preventing the proliferation of orbiting garbage.
Space is like the Mojave Desert; once you get out there past a certain point, there's really nowhere convenient to pull over, stretch your legs, buy a Red Bull, and top up the gas tank. But Canadian company MacDonald Dettwiler and Associates (MDA) have hatched an ambitious scheme to build a satellite fueling station in space that could service and restore aging satellites to working order, extending their lives for years.
The future of spycraft looks pretty heavy, if this new Boeing plane is any indication. Adding to today's parade of pretty new planes, Boeing unveiled a hydrogen-powered unmanned aircraft system Monday that will stay aloft at 65,000 feet for four days.
The Phantom Eye is not exactly sleek, but it's one of the greenest aircraft out there -- its only byproduct is water.
If you’re an ocean-transiting container ship, friction is a drag. The bigger your load, the more energy it takes to propel you through the water, and that means increased fuel costs and increased emissions. But by mimicking the hydrophobic characteristics of the water fern, researchers at the University of Bonn think they can create container ships that move faster – and more efficiently – from port to port.
