From Gizmodo: In the Future, Maglev Cannons Will Shoot Us Into Space

Am I the only one that thought of “Galaxy Express 999” anime show from my childhood when you read this?!
================================================================

Today in grandiose space ambitions that would make even Newt Gingrich balk: a $60 billion, 1,000-mile long, 12-mile high, 20,000-miles-per-hour maglev train that starts on the ground and arrives in low Earth orbit. The minds behind the Startram project think it could reduce the cost per kilo (that’s like 2.2 pounds American) for cargo from roughly $10,000 to just $50. More »

From Gizmodo: Samsung Makes the New iPad’s Screen Because No One Else Could

Apple has exacting demands when it comes to quality control, and few things need to hit harder on quality than the retina screen on the new iPad. According to Bloomberg, the only company that was able to make the screens up to Apple standards was Samsung. You know, the company Apple’s been trying to sue into the ground for months and months. Awkward. More »

From Discover Magazine: Superfast 3D Printing Yields Tiny Racecar, Church, Bridges | 80beats

car

This tiny speed racer measures 285 microns long and was 3D printed using a new technique developed at Vienna University of Technology. The printer pumps out thin lines and layers of resin, which harden when hit with a pair of photons from a laser, a kind of 3D printing called two-photon lithography. By adjusting the way the laser is produced and tweaking the formula for the resin, the team managed to make the hardening process much faster, so that what used to take hours can now take seconds. The printer can now shoot out five-meters’ worth of resin—in an extremely fine line, of course—per second. Conventional 3D printers of this sort, on the other hand, produce in millimeters per second. You can watch the racecar being made here:

To strut their printer’s stuff, the team also made miniature models of a church in Vienna and a local bridge:

From Ars Technica: Yahoo IP lawsuit: We patented “Facebook’s entire social network model”


By now you’ve heard that Yahoo has sued Facebook, alleging patent infringement. But just which pieces of intellectual property is Yahoo claiming Facebook ripped off?

Surely, you’d say, Yahoo doesn’t claim that it invented the entire social networking model Facebook is based upon—except it turns out that is almost exactly what Yahoo is claiming.

From Ars Technica: New 3D printer could create nano-devices in minutes


Researchers at the Vienna University of Technology (TU Vienna) have developed a 3D printing technology that can quickly print detailed objects in nanoscale using a process called two-photon lithography. It’s fast, too: the precision required to print objects with features measured in hundreds of nanometers in width meant the speed of previous attempts at printing nanoscale objects were measured in millimeters per second. In contrast, the TU Vienna team’s 3D printer is capable of printing lines of resin at a rate of five meters per second. In a demonstration shown in the video below, the team was able to print a nanoscale model of a 300-micrometer long Formula 1 racecar—made from 100 layers of resin, each consisting of approximately 200 individual lines—in four minutes.
