Capacitors are able to charge and discharge more quickly than batteries, and can do so hundreds of thousands of times. Batteries, on the other hand, are able to store more energy than capacitors. There are also electric double-layer capacitors (EDLCs), otherwise known as supercapacitors, that can hold battery-like amounts of energy while retaining the charge/discharge speed of regular capacitors. EDLCs incorporate liquid or gel-like electrolytes, however, which can break down under hot or cold conditions. Now, a new solid-state supercapacitor developed at Houston’s Rice University is using nanotechnology to get around that limitation.  Read More

CineSkates are soft urethane wheels for the GorillaPod Focus tripod, that allow users to d...

If you’re a videographer, and want to elevate your work from just looking competent to looking slick, one of the best things you can do is put your camera on a dolly. No, I’m not talking about a Ken or Barbie, but a wheeled camera mount that allows you to do smooth, fluid tracking shots. While the Spielbergs of the world use actual purpose-built camera dollies, lower-budget film-makers often make do with wheelchairs, skateboards, or wheeled spreaders that mount on the bottom of industrial-sized tripods. Given the popularity of JOBY’s compact and flexible GorillaPod tripods, however, it perhaps shouldn’t be surprising that someone has developed a wheel system for them – it’s called CineSkates.  Read More

Although you may not be using a Get Smart-style shoe phone anytime soon, it is possible that your mobile phone may end up receiving its power from your shoes. University of Wisconsin-Madison engineering researchers Tom Krupenkin and J. Ashley Taylor have developed an in-shoe system that harvests the energy generated by walking. Currently, this energy is lost as heat. With their technology, however, they claim that up to 20 watts of electricity could be generated, and stored in an incorporated rechargeable battery.  Read More

Steve Jobs has resigned from his post as CEO of Apple (Photo: Matt Yohe)

In what was not an entirely surprising move, Steve Jobs announced yesterday that he has resigned as Chief Executive Officer of Apple. While neither Jobs nor Apple gave a reason for his resignation, it is widely suspected that his ongoing health problems played a major part in his decision. He will remain with the company as Chairman of the Board, while former Chief Operating Officer Tim Cook has taken over as CEO, in accordance with Jobs’ recommendation.  Read More

In the recent past, we’ve seen outfits that incorporate bio-sensors and batteries, and even a bikini with integrated solar cells. One of the latest innovations in smart fabrics, however, allows a person’s clothing to act as multiple antennas. Developed at Ohio State University (OSU), the system could prove particularly useful to soldiers, who don’t want to be encumbered by a protruding whip antenna.  Read More

Fans of three-wheeled cars will tell you that the vehicles come in two configurations: delta, with the single wheel in the front, and tadpole, with the single wheel in the back. Well, now there's another type. The prototype Thrustcycle SRT has all three of its wheels in a straight lateral line, and utilizes a mechanical gyroscopic stabilizing system to keep it firmly upright even when standing still. That same system also stores kinetic energy generated by braking, extending the vehicle's range.  Read More

Scientists have developed heart tissue that contracts when exposed to light, which could p...

There's no denying that pacemakers are life-saving devices, but they do have their limitations. These include the facts that their metal leads can break, they need to be surgically accessed if their batteries run out, and they can be disrupted by strong magnetic fields. Some or all of these problems may one day become things of the past, however, due to research currently being conducted at New York's Stony Brook University - scientists there are working towards the development of pacemakers that control the heart through pulses of light.  Read More

While it’s nice to hear that Goodyear is developing self-inflating tires for cars, where does that leave bicycle riders? Still pumping, presumably? Well, not if they’re running PumpTires on their steed. As its name implies, the PumpTire is designed to automatically pump air into the inner tube, using the compressive effect of the tire meeting the ground as it turns. Once the tube reaches the desired pressure, the pumping action ceases.  Read More

New study highlights mobile device dangers for pedestrians

This year, according to the United States' Governors Highway Safety Association, pedestrian deaths in the U.S. rose for the first time in four years. While there could be a number of reasons for that increase, one likely culprit is mobile technology - or, more accurately, pedestrians' reluctance to disengage from their mobile devices when crossing the street. New research from the University of Alabama at Birmingham (UAB) lends weight to this argument and show that it's not just texting and talking that can get you into trouble when you step out onto the road.  Read More

Diamond-Power skylight panels are designed to harness solar energy, while reducing the sol...

There’s no doubt that skylights make for psychologically-nicer buildings, while also reducing the amount of electricity required for daytime artificial lighting. If they let in too much sunlight, however, they can actually increase the amount of electricity needed for air conditioning. California-based EnFocus is attacking the situation from two ends – its Diamond-Power panels diffuse sunlight to keep interior heat down, while also harnessing it to create electricity.  Read More
