Hasta La Gadget!

NASA has always used the desert as its own personal playground, and we’d imagine that its team had a blast in Arizona yesterday, as a mock parachute compartment of the Orion spacecraft was dropped from 25,000 feet above Earth. The dart-shaped object experienced free fall for 5,000 feet, at which point, drogue chutes were deployed at 20,000 feet. This was then followed by pilot chutes, which then activated the main chutes. As you’d imagine, these things are monsters: the main parachutes — three in all — each measure 116 feet wide and weigh more than 300 pounds. Better yet, the mission was successful.

Naturally, all of this is in preparation for Orion’s first test flight — currently scheduled for 2014 — where the unmanned craft will travel 15 times further than the ISS and jam through space at 20,000 mph before returning to Earth. Yesterday’s outing is merely one in a series of drop tests, and yes, it’s important to remove any unknowns from the situation: eventually, humans will be along for the ride.

AT&T’s video archives are rich seams of juicy historical tidbits, and today’s offering is a fine example. It’s sharing footage of the Bell Blit, a graphic interface that Bell Labs developed after being inspired by the Xerox Alto. Originally named the Jerq, it was created by Rob Pike and Bart Locanthi to have the same usability as the Alto, but with “the processing power of a 1981 computer.” Watch, as the narrator marvels at being able to use multiple windows at once, playing Asteroids while his debugging software runs in the background on that futuristic green-and-black display. The next time we get annoyed that Crysis isn’t running as fast as you’d like it to, just remember how bad the geeks of yesteryear had it.

The University of Maryland team responsible for the Gamera II human-powered helicopter NAA flight time record may be on its way to bagging another one — this time for altitude. With new freshman pilot Henry Enerson spinning the cranks, the gigantic four-rotor design ascended to eight feet, an unexpectedly lofty level, according to the team. The well-controlled 25 second flight was far less than the record 49.9 seconds Gamera achieved earlier, but the new altitude bodes well for its upcoming Sikorsky Prize attempt. That $250,000 award, unclaimed since 1980, requires a 10-foot altitude to be maintained for one minute, and now looks to be distinctly in the UMD group’s sights. Check the video after the break, and marvel at the ungainly quadrocopter’s latest aerial exploit.

Antennas have often capped the potential speed of a wireless link — the 450Mbps in modern 802.11n WiFi routers is directly linked to the use of a MIMO antenna array to catch signals more effectively, for example. That ceiling is about to get much higher, if A*STAR has anything to say about it. The use of a polymer filling for the gaps instead of air lets the Singapore agency create a 3D, cavity-backed silicon antenna that measures just 0.06 by 0.04 inches, roughly the size of a seed on your hamburger bun, even as it increases the breakneck pace. The new antenna generates a signal 30 times stronger than on-chip rivals at an ultrawideband-grade 135GHz, and musters a theoretical peak speed of 20Gbps — enough that 802.11ac WiFi’s 1.3Gbps drags its heels by comparison. Before we get ahead of ourselves on expecting instant file transfers at short distances, there’s the small matter of getting a chip that can use all that bandwidth. Even the 7Gbps of WiGig wouldn’t saturate the antenna, after all. Still, knowing that A*STAR sees “immense commercial potential” in its tiny device hints that wireless data might eventually blow past faster wired standards like Thunderbolt.

Eking out more power from solar cells is an ongoing challenge for scientists, and now architect André Broessel has developed a spherical glass energy generator that’s said to improve efficiency by 35 percent. Acting as a lens, the rig’s large water-filled orb concentrates diffused daylight or moonlight onto a solar cell with the help of optical tracking to harvest electricity. In certain configurations, the apparatus can be used for solar thermal energy generation and even water heating. In addition to the oversized globe, Broessel has cooked up a mobile version of the contraption for domestic use and an array of much smaller ball lenses with dual-axis tracking that offers 40 percent efficiency. These devices aren’t the first venture into concentrated photovoltaics, but they are likely among the most visually impressive. If the Barcelona-based architect’s vision of the future comes true, you’ll be seeing these marbles incorporated into buildings and serving as standalone units. Hit the source links below for the picture spread of prototypes and renders.
