TED Talks mischief: lasers killing mosquitoes by the hundreds

Malaria is a huge problem worldwide, so it’s no surprise to anyone that plenty of people spend lots of time trying to think of ways to rid the world of mosquitoes, prime movers of the disease. Nathan Myhrvold’s company Intellectual Ventures Labs (and former chief technology officer at Microsoft) is focusing on just that. Using widely available and common electronics parts, Intellectual Ventures has made lasers which can kill mosquitoes mid-flight — at a rate of about 50 to 100 per second. Myhrvold first publicly demonstrated this laser (which is made of parts of printers, digital cameras, and projectors) at the TED conference the other day, using hundreds of mosquitoes in a clear glass case to make his point. The laser’s software determines the size and shape of the target before deciding whether or not to shoot, so, for instance — it wouldn’t take aim at a person or a bumblebee. The lasers could be used to protect hospitals and clinics in areas with high mosquito populations and in areas with a high rate of malaria infestation. Now, this is surprisingly not the first time we’ve seen such a trick — though it is the first time we’ve seen video evidence of it working. There are some insanely informative (and murderous) videos at the source link. Be sure to check them out.

Update: Video is after the break.

Boeing 747 destroys ballistic missile with laser (update: photos!)

No, this isn’t a call to arms (yet), the US is simply evaluating its airborne laser weapon again. Now listen in because this latest test was a doozy. Last night at 8:44pm Cali time, the Airborne Laser Testbed (ALTB) successfully “destroyed” a liquid-fueled ballistic missile from an airborne platform, according to the Missile Defense Agency. A first for the directed energy weapon that we’ve been following since 2006. The dirty work was achieve by a modified Boeing 747-400F airframe fitted with a Northrop Grumman higher-energy laser and Lockheed Martin beam and fire control system. After an at-sea launch, the ALTB used a low-energy laser to track the target. A second, low-energy laser was used to measure and compensate for atmospheric disturbances before the megawatt-class laser was fired, “heating the boosting ballistic missile to critical structural failure.” The entire episode was over just two minutes after missile launch. Good work generals, but let’s see you fit that laser to a shark if you really want to impress us.

Update: Infrared images of the ALTB destroying the short-range ballistic missile after the break.

This Is a Mosquito Getting Killed By a Laser

You’re looking at a mosquito who got taken down mid-flight by a “Death Star” laser gun designed by Nathan Myhrvold. The malaria-carrying pest never saw it coming, but you can watch everything happen over and over again in this video.

The idea behind the “Death Star” laser is that it could be used to control mosquito populations in developing countries in hopes of reducing the number of deaths due to malaria, a disease frequently carried by the flying insects. The device was shown off during the TED 2010 conference and does in fact appear to be capable of tracking and killing mosquitoes. Oh, and it was built out of parts found on eBay. [Wired]

AAXA intros L1 laser pico projector / media player

It’s claim on the title of “world’s first laser pico projector” might be a tad dubious, but AAXA Technologies’ new L1 projector may just be the first to hit the market, with it set to start shipping on February 12th. Like other laser-based models, this one promises to always stay in focus, and even project images (800 x 600, up to 50-inches) on curved surfaces with ease. Somewhat uniquely, you’ll also get a built-in media player, along with the usual USB port, memory card slot, and composite and VGA inputs to actually pump media through the device. Just don’t expect the same low, low price seen on some other pico projectors lately, as this one’s set to run a hefty $599.

Germanium lasers offer ray of hope for optical computing

Bandwidth scarcity, is there any more pressing global issue that we’re faced with today? We think not. Given the exponential growth in both computing power and software’s exploitation and expectation of greater resources, it’s no surprise that at some point we’ll have to look beyond simple electrical currents as the transporters of our data. One bold step taken in that direction has been the demonstration of an operational germanium-on-silicon laser by researchers at MIT. By tweaking the electron count in germanium atoms with the help of some added phosphorous, they’ve been able to coax them into a photon-emitting state of being — something nobody thought possible with indirect bandgap semiconductors. Perhaps the best part of this is that germanium can be integrated relatively easily into current manufacturing processes, meaning that light-based internal communication within our computers is now at least a tiny bit closer to becoming a reality.

Penn State’s optical wireless tech does gigabit, bounces off walls

Penn State's optical wireless tech does gigabit, bounces off walls

We love our WiFi, but it’s far from perfect. Speed depends greatly on conditions, magnetic waves don’t always play nicely with sensitive equipment, and the ability for someone to drive by and steal your precious infos is always disconcerting. Researchers at Penn State have what they believe is a better solution: light. The team uses laser diodes to convert data signals to light, then photo diodes on the other end to convert it back to data, a system that (unlike others we’ve seen) doesn’t require direct line of sight as the light will bounce off of walls — except those painted black (sorry goths). Data access could easily be constrained within a single room or, if it was needed elsewhere, wired relays could bring it through walls. Speeds at this point are already at the 1Gb/sec range, twice what Siemens was able to manage a few weeks ago, and enough for wireless transmission of high-definition video. Someday your Wiimote and remote might not be the only things beaming back at ya in the living room.

One megajoule laser brings nuclear fusion power closer to reality

When you think of the laser these days, you’re most likely imagining a giant beam that can scorch a few buildings within seconds. Putting your evil thoughts aside, why not think smaller yet more powerful, and something that may change the future of mankind for good? We’re talking about the National Ignition Facility that has recently produced the world’s first megajoule laser, which only lasted for a few nanoseconds but is still a milestone for nuclear fusion development (read: clean energy on a massive scale). In a nutshell, this laser should be able to produce sufficient X-rays in order to fuse hydrogen nuclei, and it also has financial and efficiency advantage over other systems by having an exposed reactor core instead of one shielded by a huge magnet. That said, until the NIF tries the laser on fuel capsules this summer, we can only be hopeful.

Laser-based ‘clock’ shortens beam as wake-up time draws closer

It’s probably not the clock you need to build if being punctual is your modus operandi, but it’s sufficiently nerdy nonetheless. One Nirav Patel — which may or may not be related to our own Mr. Patel — decided to hand craft his own “sleep remaining indicator,” which utilizes a slowly rotating servo, a laser beam and a timer in order to work its magic. Put simply, the beam gets shorter and shorter as one’s wake-up time draws near, but oddly enough, you’ll never be able to see its awesomeness if you’re actually sleeping. Quite the conundrum, no?

Microvision laser projection gun hands-on

You didn’t think CES was over, did you? Saving a true gamer’s delight for last, we went along to meet with Microvision’s reps today and were introduced to its PicoP laser projector and gun gaming peripheral. The projection tech employed here is unique, as each pixel (848 x 480 resolution) is itself an RGB laser reflecting off a mirror which flips 60 times a second. What that results in is a permanently focused projection, no matter how much you wiggle, jiggle or maneuver the projector. The whole thing fits within 6cc and was designed to be embedded into phones. We snapped a few pics of the standalone projector and then moved on to the rifle gaming controller. Come along after the break to check out our hell-raising skills on video, as well as some more in-depth impressions of the hardware.
