Facebook to beam the Internet from the sky using lasers

Facebook to beam the Internet from the sky using lasers

When your core business is essentially dependent on the Internet, it makes sense that you'd want everyone to have access to the Internet as well. Google has its Project Loon and Facebook has Internet.org. Of course, those are lofty goals, but the question is always "how". Unlike Google's balloons, Facebook will be using satellites, drones, and lasers. Yes, lasers. Mark Zuckerberg has just posted online, on his Facebook account no less, a teaser of what's to come, with lasers being shot from the sky to deliver the Internet, and Facebook, to everyone.

U.S. Army and Air Force build laser-blasting bomb-disposal vehicle

U.S. Army and Air Force build laser-blasting bomb-disposal vehicle

The latest technology from the U.S. Air Force and Army that could head into the battlefield involves harnessing laser power to destroy fields of landmines from a safe distance. The Air Force-built laser will be incorporated into the Army's mine-resistant, ambush-protected vehicles (MRAPs). The specific prototype is known as RADBO which stands for Recovery of Airbase Denied by Ordinance. It's a lengthy moniker, but it accurately describes the missions in which the laser should be used--turning an airfield that is littered with landmines into a usable airbase with as few casualties as possible.

Homemade 40W laser shotgun: don’t try this at home

Homemade 40W laser shotgun: don’t try this at home

Science fiction just got a DIY treatment and got closer to home. It won't be enough to stop a truck dead on its wheels like Lockheed Martin's contraption, which is unabashedly a weapon of destruction, but YouTube user Styropyro's homebrew laser shotgun is still powerful enough to do some damage and burn things, even wood. And perhaps the scariest part about it is that it is something that makers, DIYers, and science enthusiasts can build right at home, with just the right tools, the right materials, and the right motivation.

Lasers of the future will be capable of reproducing gamma-ray bursts

Lasers of the future will be capable of reproducing gamma-ray bursts

If you thought lasers were powerful now, just wait a couple of years. A group of researchers have said that new laser technology coming down the pipeline over the next few years will able to reproduce a gamma-ray burst — an explosion in space that emits more energy within a few minutes than the sun in its lifetime — here on Earth. One of the scientists who contributed to a study on this possibility says the goal is to learn exactly what happens within "some of the most energetic events in the universe."

Super-powerful laser creates plasma hotter than the sun

Super-powerful laser creates plasma hotter than the sun

The sun is very, very hot. We have all known this since grade school. Scientists have created an incredibly powerful laser that can create plasma that is many times hotter than the center of the sun. The incredibly powerful laser that is able to create the intensely heated plasma has 200-trillion watts of power. The photo here is a shot of that laser and the incredibly bright spot is the super hot plasma.

ISS could mount lasers to blast away space debris

ISS could mount lasers to blast away space debris

As the ISS floats above earth, it's actually hurtling around its orbit at 17,000 mph. Any debris that it encounters at that speed could have major consequences, so the ISS often has to change course throughout its orbit just to avoid space debris from previous missions. According to NASA, there are about 3,000 tons of space debris in a cloud around Earth in low-Earth orbit. There is another belt of debris higher above the earth in geo-synchronous orbit. A team of Japanese scientists proposed a solution using lasers to blast the debris before it can damage the ISS.

Star Wars virtual keyboard taps R2-Q5

Star Wars virtual keyboard taps R2-Q5

The original R2-D2 virtual keyboard is gone. It's forever on the shelves and in the display cases of collectors around the world, for the rest of time. For those of you that missed it, there's always the imperial droid R2-Q5, his black and orange-ness, as we call him around here. This fellow is being released by the same company that originally released his R2-D2 equivalent, and this version will be released on May the 4th, 2015, just in time for the most important holiday of the entire year.

How NOT to play space invaders: with a laser-cutter

How NOT to play space invaders: with a laser-cutter

Space Invaders is right up there in the gaming hall of fame, together with the likes of Pong and Pac-man, which have sparked the imagination and creativity of many young ones, despite or even probably because of the simplistic 8-bit style. And when it comes to imagination and creativity, nothing beats this new generation of makers and their tools. Like this one Martin Raynsford, who turned an essential tool that he uses for work into, what else, a physical, real, and probably really dangerous game of Space Invaders.

BoXZY crams a mill, laser, and 3D-printer into one desktop maker

Makers and artists, rejoice! BoXZY wants to bring the power of manufacturing-level tools, once only available to industry giants, to your desktop. BoXZY is setting itself apart on Kickstarter by offering more than just 3D-printing. BoXZY is designed to be an all-in-one machine shop, functioning as a 3D-printer, mill, and a laser engraver. Each tool exists as a rapid-change attachment, allowing the user to swiftly switch between mechanisms. Its creators, Justin and Joel Johnson, want to break the barriers like cost, location, and space that individual makers encounter in the industry.

ODiN Aurora mouse projects a laser trackpad onto surfaces

ODiN Aurora mouse projects a laser trackpad onto surfaces

ODiN is a mouse that functions like a trackpad, only it uses projected lasers rather than traditional hardware. The design, upon first glance, appears to be a Transformer, but it's not -- it's the Norse god of war, and the projected image includes a laser spear to drive that theme home. The mouse works by sitting on a desk and projecting a "trackpad" onto the surface in which the user can control their computer's cursor. More details after the jump!
