Scientists develop superconducting material that doesn’t need cooling

Posted in Tech/Sci News by Alex on March 20th, 2008

A team of Canadian and German scientists have found a way to fabricate a superconducting material, made of a silicon-hydrogen compound, that does not require cooling. They say that the breakthrough means we will be able to cut the power usage of all sorts of devices from refrigerators to cell phones.

This new material is super-compressed instead of being super-cooled like conventional superconductors, allowing scientists to create superconducting wires that work at room temperature.

Superconductors offer no electrical resistance, meaning that energy will not be lost while a current is traveling along a superconducting wire.

If the scientists can find a way to mass-produce this material, we could see a new age in electronics. Battery life would improve dramatically for all sorts of gadgets, and power usage would go down for anything that stays plugged in. Hopefully they can figure out the magic formula soon.

DARPA wants displays in contact lenses for soldiers soon

Posted in Tech/Sci News by Alex on March 20th, 2008

Bionic eyeToday’s heads-up displays worn by soldiers are bulky and probably quite uncomfortable. DARPA is seeking to solve all that with contact lenses that sport a display to overlay graphics and information on top of the soldiers’ vision.

Specifically, the agency is looking for “information on technology areas for the creation of micro- and nano-scale display technologies for the purpose of creating displays that could be worn as transparent contact lenses”, and they want that information within three to five years.

This sounds like a very ambitious project, but with DARPA behind it maybe, just maybe, we’ll actually see it come to life. Perhaps this is a job for UW scientists and their contact lenses with circuits?

Intel trying to get WiFi to rural areas with 60-mile links

Posted in Tech/Sci News by Alex on March 19th, 2008

Intel RCP WiFiWiFi is commonplace in today’s large, booming cities. You can probably find a few hotspots walking around on any street. However, for rural areas, especially in undeveloped nations, WiFi and any other kinds of internet access are hard to come by.

Intel is trying to solve the problem with its Rural Connectivity Program (RCP). The company is utilizing a new technology consisting of a processor, software radios, and an antenna to enable wireless signals to travel up to 60 miles.

Wireless access is the way to go in these countries, as there are several problems with putting in wires. They are too expensive, too long for a good signal, and would often get dug up and sold.

So far, the RCP has been tested in India, Panama, Vietnam, and South Africa with successful results. “We’re seeing a lot of interest in the industry,” said Jeff Galinovsky, a senior platform manager at Intel. “Every time we talk about this, they say, ‘We need this yesterday’.”

This is a great program, and combined with efforts to make cheap laptops targeted at these countries will help them catch up to the information age. It will be great to see what the internet is like with so many more people with such different perspectives on board.

Futuristic remote concept controls TV with no touching required

Posted in Design/Concept, Gadgets by Alex on March 19th, 2008

Touchless concept remoteA Dutch design student has dreamed up a simple remote that can control a TV without being touched at all – perfect for sitting in a kitchen where the cook’s hands may be covered with food.

The remote adjusts volume when you move your hand over or under it, tilting itself at the same time. It changes channels when you flick a finger through the cavity in the middle of the remote. Finally, it turns the TV off when two fingers meet in the middle of the cavity, and turns it back on when two fingers spread apart from the middle.

Of course, we’re years away from such a remote. Nevertheless, it looks like a great idea for the time when we can finally create such a gadget. Check out a video of the concept remote in action after the jump. Read more »

Scientists working to create tiny spy bat for the Army

Posted in Tech/Sci News by Alex on March 18th, 2008

Army spy batThe University of Michigan has received a $10 million, five-year grant from the Army to develop a miniature spy bat complete with cameras, radar, recharging capability, a self-guidance system, and a radio to send surveillance data.

Scientists will try to shrink current electronics down to allow the bat to be six inches in length, weigh four ounces, and use only one watt of power. They will attempt to create a navigation system 1,000 times smaller and 1,000 times more energy efficient than today’s systems, and a communications system that’s one-tenth of today’s size.

New laptop fan cools with no moving parts

Posted in Tech/Sci News by Joel Levin on March 18th, 2008

rsd5_solid_state_fan.jpgThe nice folks over at Thorn Micro Technologies have developed an awesome new laptop fan – the RSD5. It is a solid state fan (no moving parts!) that uses an electrical current to generate airflow. More airflow, in fact, than standard mechanical fans.

While typical mechanical fans generate a breeze of 0.7 – 1.7 meters per second, the RSD5 can output a cooler 2.7 meters per second. What’s more impressive is that it stays completely silent while cranking out this kind of airflow.

One of the best things about this fan is that it’s the size of a microchip. The researchers who developed it are hoping to one day build these solid state fans directly into other chips, creating self-cooling processors and other chips that stay cool on their own. The new fan is very cool (no pun intended), but it would be interesting to see what kind of effect this would have on laptop battery life.

Electrolux Inspiro smart oven – no thinking required

Posted in Tech/Sci News by Joel Levin on March 18th, 2008

electrolux-inspiro-oven.jpgElectrolux has unveiled their new Inspiro auto-adjusting oven. What is an auto-adjusting oven, you ask? It’s an oven that automatically detects optimal temperature and time settings depending on what is placed inside.

The company describes the technology as similar to auto-adjustment technology used in many modern cameras to figure out settings for aperture, focus, exposure time, etc. depending on what is in the frame. I know what you are thinking, and the answer is: yes, the Inspiro has a manual mode for those who want control over how their food is prepared.

This is a pretty cool idea, but we’re not entirely sure who the target audience is. Everyone I know who cooks on a regular basis likes to be able to tweak appliance settings. But who knows, perhaps this will be the next big thing and in a couple of years everyone will own one.

No word on price or release date as of now.

Samsung announces world’s slimmest 8 megapixel cell phone camera module

Posted in Tech/Sci News by Alex on March 18th, 2008

Samsung 8MP cell phone camera moduleSamsung has announced an 8 MP CMOS camera module that it claims to be the thinnest of its kind, measuring a tiny 8.5 mm thin.

Notable features of the new module include anti-shake, a 1 cm macro, face tracking technology, and a smile shutter feature that knows to snap a picture when it detects people smiling.

The company expects the new module to replace the 5 MP cameras found in today’s high-end camera phones by the end of the year.

Cell phone cameras are quickly catching up to today’s digital cameras, which will probably become extinct in a matter of years. It seems that putting all sorts of gadgets in one box is the way to go these days, so if you are thinking of buying a new camera hold off for a few months and buy one of the 8 MP cell phones when they are released.
