And you thought your last move was difficult. The process of moving a large building, from a mansion to a railway station, from one location to another is a major engineering challenge. Here are some eye-popping photos of massive structures in transit.
Microsoft’s Kinect is great, but it has its limitations. Not so MIT’s new nano-camera, though, which uses similar technology but can weave the same magic with translucent objects, and even work in snow or rain.
Forget printing circuits: how about drawing ’em instead? At least, that’s what you can do with this rollerball, which spews out conductive silver ink to let you doodle circuits all day long.
In the future we should hope for all of our displays to be OLED; it’s thin, light, deep with color, and energy efficient to boot. It’s also incredibly expensive. That could soon change, though, thanks to a jumped-up inkjet printer.
Li-on batteries are great and all, but there’s a barrier preventing them from storing much more power: they, um, tend to catch fire
The Yangtze River is the third longest in the world and it’s served as a critical artery in the beating heart of China’s economic boom. It’s also incredibly wide at points—which has forced China to become a top contender as the builder of the most advanced long-span bridges in the world. Taizhou Bridge is definitely one of those bridges.
Hydrogen is one of the most promising fuels of the future
You probably have no idea where the ink in your pen comes from, much less whether it’s a simple factory process or demanding of more expertise. Josh Velson, a chemical engineering consultant for bio and petrochemicals, has your answer.
