Russia hopes 'clean' rockets are the future of spaceflight
If you ask Russia, modern rockets are hindered by not just their engines, but their fuel -- the chemicals just aren't powerful enough to carry increasingly heavier loads and keep costs in check. To that end, the country's Advanced Research Foundation has conducted what it says is the first successful test of a full-size pulse-detonation engine (where rapid-fire detonation waves combust the fuel and oxidizer) running "clean" fuel. The oxygen-kerosene mix isn't so much eco-friendly (although it does burn more cleanly) as very efficient. Its high thermodynamic performance, combined with the extra efficiency of pulse-detonation itself, would let rockets either carry more cargo into space or reduce costs by getting vehicles into orbit faster.
Jet-fueled electronics are coming
Fuel cells may be a practical reality, but there aren't many choices for the fuel itself -- you usually have to rely on hydrogen, which dictates where and how those cells work. The University of Utah may have a clever alternative in store, however. Its researchers have developed a cell that runs on JP-8, a jet fuel used by American warplanes in harsh climates. The cell uses enzymes to turn propellant into electricity without requiring lots of heat or a perfectly clean mixture; it works at room temperatures even when there's sulfur in the mix, making it far more useful than previous attempts at JP-8 cells.
China's new liquid oxygen and kerosene-fueled rocket engine lights up for testing
Liquid oxygen and kerosene, that's what fuels China's new -- and freshly tested -- rocket engine. When fired up on Sunday, it withstood temperatures as high as 5,432 degrees Fahrenheit (3,000 degrees Celsius) for 200 seconds and powered through almost 20,000 revolutions per minute in a rotational test. "The successful tests confirm the reliability of China's LOX / kerosene engine," test commander Lai Daichu told China Daily. According to China Central Television, the engine is non-toxic, pollution-free and the first of its kind for which China holds proprietary intellectual property rights -- though similar engines have been used by other space agencies. The engine is on track to lend the upcoming Long March 5 rocket a total of 118 tons of thrust, giving it enough oomph to launch a 25-ton payload into low-earth orbit or 14-ton cargo into geostationary orbit. Its expected to haul additional portions of the country's space station and aid lunar exploration, but the first voyage isn't slated until 2014.

Yves Rossy's jetpack loops a hot air balloon, looks great doing it (video)
Looks like Swiss daredevil Yves Rossy is back to the, well, daredeviltry. On November 5, 2010, the self-described Jetman lept off a platform attached to the side of the Esprit Breitling Orbiter hot air balloon and, after reaching an altitude of 2,400 meters (7,874 feet), came back to loop around the thing twice. He was aided in his endeavor by a new, smaller wing (two meters across) with four jets, and executed the maneuvers using only his body movements to steer. Afterward, he deployed his parachute and landed in Denezy, in the Swiss canton of Vaud. We might also add that we tried to get one of these devices for an Engadget Show giveaway, but our lawyers seem to think it's a terrible idea. Video after the break.
Swiss daredevil cruises the friendly skies with winged jetpack
Sure, watching Wowwee's FlyTech Dragonfly buzz around the room at your command elicits quite a few positive emotions, but we can't even fathom the thrill (not to mention the feeling of impending death) that would come from cruising the skies via jetpack. Yves Rossy -- a Swiss daredevil whom we all look forward to living through vicariously -- says he has become "the first person to gain altitude and maintain a stable, horizontal flight thanks to aerodynamic carbon foldable wings." While we've seen jetpacks before, and realize that folks have taken to the air on similar devices in years past, Reuters is giving us a sneak peek at Rossy's flight, which he took on the kerosene-powered, back-strapped vehicle -- and we admit, it looks like quite the thrill ride. So if you're looking to quell your fears before picking up one of your own (hopefully) in a few years, be sure to hit the read link for a live action video (and a good reason to grin).[Via Fark]
