Eco 's0ccket' Ball Generates Enough Juice for LEDs or Battery Charges


With the 2010 FIFA World Cup just around the corner, the whole world (yes, even the States) will soon be swept up in soccer mania. The event will certainly produce an economic surge in host country South Africa, but, thanks to four Harvard students, soccer could produce more energy for the African country, too. According to Planet Green, the s0ccket ball generates and stores enough energy to power an LED light or charge a small electronic device. After 15 minutes of kicking, you could power an LED light for three hours. (It's similar to those flashlights you shake to charge.) That's huge for a country that still struggles with its electronic grid.

The s0ccket team, composed of four women from Harvard, recently tested prototypes in South Africa. There's no intention for this ball to be used in games, but, in a place where kids make soccer balls out of trash, the s0ccket is a godsend. "You won't see David Beckham using it," said one of its creators, Jessica Lin. "But it's a big improvement over some of the makeshift balls the kids create from things like old plastic bags."

If this product catches on, it could definitely have a lasting effect on the people of South Africa -- long after the last echoes of World Cup cheers and chants have died. [From: s0ccket and Planet Green, via: Ubergizmo]

Design Concepts: Bright, Brilliant and Bold LED Dresses


The Web is teeming with the unrealized ideas of both students and established designers who set out to produce astonishing renderings and prototypes for unusual products. Unfortunately, due to the lack of time, money, or technology, many of those products never move from the planning stages to the mass market. But that doesn't mean we can't salivate over their creations, nevertheless.

One of the best indicators of the shift from one era to the next is fashion trends, and nothing says future like tech-inspired dresses. We've seen an explosion of LED-embedded frocks hit the Internet over the past few months, and we can no longer dismiss them as mere experiments gone awry. While tech and fashion have fused in the past, we think that we will soon start to see this kind of synthesis in the mainstream. While they're no great indicators of taste, just think of the LED belt buckles that were in style a couple years back. And, on the other end of the taste spectrum, we have Hussein Chalayan's futuristic couture and Viktor and Rolf attaching floodlights to their runway models. Face it: Tech invades every facet of life, fashion being no exception.

Home Disco iPod Dock Is Like Studio 54... in Space


Designer Moritz Waldemeyer loves lights. Having worked with the likes of Hussein Chalayan and Ron Arad (on products like Arad's famous Lolita chandelier), and having designed LED suits for U2 and OK Go, Waldemeyer is something of the go-to guy when you want digital haute design. He was recently challenged by Wallpaper, one of our favorite design-porn mags, to design a product based on the concept "Home Disco."

Waldemeyer totally nailed it. Home Disco is an unassuming box that magically transforms a room into 'Saturday Night Fever' within a laser cage. Incorporating speakers and an iPod dock, alongside its 72 lasers (by our count), Home Disco also boasts a smoke machine -- which pretty much completes the list of ingredients for an all-night, Donna-Summer-in-space party.

Klipsch LightSpeakers Screw In, Turn On, and Rock the Room

By using the power supply and mount for a light bulb socket, Klipsch's newest invention, a LED-turned-speaker that creates an integrative stereo system, may bring sound systems to ceilings. Using a remote to sense the device and connect it to a local base station, tunes are sent to the gadget, for the perfect "where-is-that-ambient-noise-coming-from" vibe for any room.

On top of lighting the roof on (musical) fire, LightSpeakers also have a built-in LED, so rooms won't darken due to missing bulbs. What it doesn't have, it appears, is a sub-woofer, so we'd stick to orchestral arrangements instead of hip-hop, but Engadget imagines Klipsch has a wireless woofer somewhere in the pipeline. Though not exactly cheap (a bundle, which includes two speakers and a base station will set you back $600, while a lone speaker is $250), each area can accommodate four speakers and a transmitter can be programmed to a total of two areas.

Useful but Dangerous: LED Traffic Lights Save Energy, Hide in Snow

LED Traffic Lights Save Energy, Hide Under SnowBy now, you should know that every technological advancement comes with a major downside. The assembly line brought cheap motorized transport to the masses, but pumped countless tons of atmosphere-destroying pollutants into the sky. While lithium-ion batteries gave our cell phones and laptops the ability to last all day, they have an unsettling tendency to burst into flames when you least expect it. Not surprisingly then, LED traffic lights have their own potentially deadly pitfall.

What makes LED traffic lights so appealing is efficiency. They last years without being replaced and use up to 90-percent less energy than the incandescent precursors. Unfortunately, all that efficiency removes a crucial ingredient that urban engineers have been relying on to keep intersections safe -- heat. All that wasted energy from an incandescent bulb is released as heat, which, in a storm, melts ice and snow and keeps the signals clear. LEDs, on the other hand, burn so cool that such things merely collect on the surface, obscuring lights completely.

Philip's Interactive LED Tattoos Could Be the Future of Body Art


Ah, human progress. It's long been possible to get drunk with your friends and make a permanent mistake on your body on spring break in Mexico, but soon you'll be able to do it electronically, too. That's right, we are entering the era of the LED tattoo.

Researchers at the University of Pennsylvania have been developing micro-thin, flexible, silicon electronics that have already been successfully implanted under the skin of mice without any harm. These devices can conform to the body's shape without causing any irritation or interfering with its normal physiological processes. (The silk is eventually dissolved and absorbed by the body.)

Gift Guide: Shift and Ctrl Key Lights


Shift and Ctrl Key Lights
(Style-o-Phile, Under $50)

An interesting piece of lighting has the ability to totally transform the ambience of a space, as well as bring other design elements into frame. The Shift and Ctrl Key Lights ($19.90 each) are an inexpensive, novel, and still touchingly geeky solution. The oversize keys come in both yellow and white (we like the cool minimalist look of the white) and are lit with energy-saving LEDs. Perfect for students, or even livening up an office or home workspace, these lights have just the right amount of whimsy without being overly gimmicky. The only downside is that Alt and Delete lights are not yet available to compliment Ctrl for the ultimate (end) task lamp.

Cutting-Edge, Eco-Friendly LED TV for Less Than $2,200?


A reader writes: I need a good TV for my living room, and I've decided that LCD, particularly LED, is the way to go. I've heard that some plasmas can look better than LCDs, so I definitely want good video quality, but I heard they use up a lot of energy and I don't want to break the bank if I can avoid it. Also, I'd like something that doesn't use up too much power. Please... just tell me what to get!


What up, reader? Indeed, the Plasma vs. LCD conflict is a tough one, as plasma does traditionally provide better black levels, which can translate to superior contrast between dark and light onscreen, especially valuable when watching high-definition movies now in the Blu-ray era.

The good news is that LCDs are continuing to evolve, with the switch to energy-saving LEDs (light-emitting diodes) as their light source (versus more common cold cathode fluorescent lamps, if you want to get technical). The Next Big Thing in energy-efficient televisions is local dimming LED, which can make specific areas of the screen lighter or darker depending upon the picture being displayed. The improvement can be absolutely stunning, imparting more drastic blacks and a much-needed boost to the dynamic contrast ratio, rated at a mind-boggling 2,000,000:1. Unfortunately, a lot of these LED TVs are pricey, but we've found one from good ol' bang-for-the-buck Vizio.

LED Eyelashes Brighten Eyes... Unnaturally

Down in the dumps? Got a bad case of the Recession blues? Pints of Chunky Monkey and Gilmore Girls reruns not doing the trick anymore? Don't worry, ladies, a newly released cosmetic device may finally bring back that certain "twinkle" in your eye.

Designer Soomi Park's latest eyelash accessory features LED technology that brighten up the eyes of the wearer. The coolest thing, besides being able to land an airplane with the bat of a lash, is that the lashes are also connected to a tilt sensor, which turns the lights off and on with each head movement. According to the designer, the lashes were created as "a product that speaks to many Asian women's desire for bigger eyes." And how!

LED Lights Let You Pimp Out Your Couch, Neon-Style

Remember when everyone installed those neon lights underneath their cars, like in 'The Fast and The Furious?' We thought that trend had died out like Paul Walker's acting career.

Now, thanks to LIT's LED lighting kit, you can relive those days in the comfort of your own home. These LED tubes can be installed around or under just about any piece of furniture in your house, giving it that sci-fi or street racing feel you've been looking for. According to DVICE, the basic kit costs $210 and includes a 37-inch adjustable LED tube, a remote control, and a power supply. If you just can't get enough of that neon glow, additional tubes are available for $75 to $88. You can choose just about any color of the rainbow with the remote, or you can set the lights to cycle through each color so you'll never get bored with just one.

U2 Takes Massive Transforming Screen on Tour

Twenty years ago, as one of the world's biggest rock bands, U2 could appease their fans by simply playing "Where the Streets Have No Name" on a building rooftop. Twenty years later, U2 is still huge, and their live performance has evolved into a gargantuan show of lights, screens, and over-the-top stage props. Don't believe us? Check out the band's expanding screen currently in use on the U2 360° tour.

The display, made by Hoberman Associates and Innovative Designs (also responsible for the mammoth screen used on U2's PopMart tour), contains 888 individual screens for a total of 500,000 LED pixels. By using hundreds of small screens that expand and contract in their distance to one another, the screen can literally change its shape. And because the space between each screen is adjustable, it can also take on a transparent quality that allows fans to see images projected in 360 degrees without blocking the view of the band. To see the monstrous screen in action, check out the video here. [From: Core77]

Tesla Model S Now Official


After a brief period of unofficial officialness yesterday morning, Tesla has rolled out the Model S to a sea of eager photographers. The company's also revealed specs for the EV: this seven-seater can go from 0 to 60 MPH in 5.6 seconds, boasts a top speed of 120 MPH, features a dashboard display and a 17-inch main touchscreen monitor. It's fully 3G capable, sports HD and satellite radio, uses LED and neon exterior lights, smart-key power, and push button gear selector. While that $49,900 base price will get you a battery that's good for 160 miles per charge, 230-mile and 300-mile range packs will be available. On a 220V outlet, the company says it'll charge in four hours with a 45 minute "QuickCharge" option, and you should be able to swap batteries if necessary in under 8 minutes. Excited? Find a way to control yourself, this baby isn't going into production in Q3 2011. Check out a brief glimpse of the interior after the break.

Yankee Stadium Goes Big With New Jumbotron


With spring training now in full gear and the regular season just around the corner, baseball fans have plenty of reasons to look forward to the 2009 season, 3D-enhanced baseball cards being among them. Although New York Yankees fans had to say goodbye to the historic Yankee Stadium last year, they'll be pleased to find one of the largest TV screens in the world installed next door at the new $1.3 billion Yankee Stadium.

The Mitsubishi Diamond Vision LED display spans a massive 6,000 square feet. The huge, high-definition outdoor screen, made up of 8,601,600 LEDs, will be able to pump out four separate video feeds at a time, and can even do live picture-in-picture. Wired also reports that the new stadium will contain over 1,400 other video screens, so you won't have to worry about missing a play if you get the snack bar munchies or need to run to the bathroom. Fans should have no problem seeing the towering 60-foot-tall screen, although the action on the field might be harder to discern (especially for those who can't afford to pay $600 for a decent seat).

New Philips LED Light Bulb Lasts for 45,000 hours


Philips has been hitting us with some out-there lighting concepts lately, but the company's Master LED light bulb is actually already on sale in Europe and is set to brighten up Stateside lives around July. The 40W-equivalent bulbs should run between $50 and $70, and expected lifetime is set at 45,000 hours -- just slightly more than a CFL's 10,000 or a standard bulb's 750 hours. The Master is certainly a damn sight nicer looking than the other mutant LED bulbs we've seen, but we'll see if consumers are ready to jump on another more-expensive-upfront lighting tech so soon after CFLs have hit the mainstream.
