An experienced freelance writer, videographer and television producer, Ben's interest in all forms of innovation is particularly fanatical when it comes to human-powered transportation, film-making gear, environmentally-friendly technologies and anything that's designed to go underwater. He lives in Edmonton, Alberta, where he spends a lot of time going over the handlebars of his mountain bike, hanging out in off-leash parks, and wishing the Pacific Ocean wasn't so far away.
Of all the bicycle light setups out there, Revolights has got to be one of the most unique. Using rim-mounted LEDs, it turns the bike's wheels into very eye-catching head- and tail-lights. Its San Francisco-based creators are now set to release a new version of Revolights known as Eclipse +, which adds wireless functionality to the mix.
Despite what various spy movies may have us believe, sending people into buildings' ductwork isn't a good idea. That said, those ducts do need to be cleaned periodically, otherwise the human inhabitants of the buildings can develop serious respiratory problems. Robots have been designed to do the job, although they've generally been wheeled or tracked devices that can only move horizontally. Now, however, scientists at UC San Diego's Jacob's School of Engineering have created DucTT – a highly-efficient robot that can climb up ducts, and run for up to six hours on one charge of its battery pack.
Our sense of touch is made possible thanks to thousands of "mechanoreceptors," which are distributed throughout our skin. The more pressure that's applied to one of these sensors, the more electrical pulses it sends to the brain, thus increasing the tactile sensation that we experience. Led by Prof. Zhenan Bao, scientists at Stanford University have now created synthetic skin that contains electronic mechanoreceptors, which could give prosthetic limbs or robots a sense of touch.
When liquids stick to steel for long enough, the steel corrodes or becomes contaminated. Unfortunately, however, porous surface coatings that repel liquids also tend to make steel weaker … until now, that is. Scientists at Harvard University have recently discovered that their existing SLIPS (Slippery Liquid Porous Surfaces) technology not only causes liquids to roll right off, but it actually makes steel stronger.
Most fingerprint scanners work the same way – the pad of the finger is pressed against the scanner’s glass surface, light is shone through the glass onto it, and the light that’s reflected back by the minuscule valleys between the print’s ridges is used to create an image of the print. It’s a system that’s usually effective, although it can fail to read prints that have been flattened by age or damaged, plus it can be fooled by gelatine casts of fingerprints. That’s why scientists from the Paris-based Langevin Institute have developed a more reliable scanner, that looks below the skin's surface.
Various bicycle components companies have been attempting to market suspension handlebar stems since at least the 90s, mostly to little success. Indeed, many of those stems are now mocked, with their overbuilt construction, pogo-like springs or stiff elastomer dampers. But now Michigan-based manufacturer Aeroforge is taking another crack at it, using modern technology to create its StaFast stem. We took it out for a few rides to see how much difference a couple of decades make.
Although we've seen a number of bikes with built-in locks lately, the Dutch-made BluLocks bike still manages to bring a fresh approach to the concept. It combines an external chain with a locking mechanism that's located inside the seat tube.
At first glance, it's certainly possible to think that the Hungarian-made
Gauswheel Spirit is sort of a low-rider unicycle, or that it has a
motor. In fact, though, it's an inline two-wheeler that's entirely
human-powered. It's also a unique alternative to a skateboard, scooter
or roller blades (or perhaps a combination of all three), that'll
definitely get you noticed. We recently had a chance to try it out for
When it comes to bicycles with different types of seating positions, everyone is familiar with uprights and recumbents. There is, however, a lesser-known third option – prone. While these have formerly been limited to one-off bikes aimed at speed record attempts, Bird of Prey Bicycles is now offering a semi-prone aimed at everyday users. It may look a little quirky, but it's claimed to have several advantages over other bikes.
Because regular cameras just process visible light, the images that they produce look like what we see with our own eyes. By contrast, hyperspectral cameras process additional wavelengths, showing us things that we wouldn't otherwise be able to see. Unfortunately, they also tend to be big, expensive, and thus limited to scientific or industrial applications. That could be about to change, however, as scientists from the University of Washington and Microsoft Research are creating a compact, inexpensive consumer hyperspectral camera. It may even find its way into your smartphone.
