Hacking tool for warriors

It's no longer about who has the biggest guns. A major part of modern warfare is command, control and communication. You can have the deadliest weapon in the world sitting in its silo waiting for launch, but if the enemy messes up your communications network, you might as well have traded it in for a Volvo for all the good it will do.

It's relatively easy to hack into the enemy's network from an office miles away from the action, but what if a grunt needs to isolate the target from using cell phones or even email to call for reinforcements? The US military is developing a portable device that will make hacking into any wireless network, from mobile to satellite signals, easy enough for field use.

Q-Sound's solar-powered Bluetooth headphones

Ready for the Q-Sound? I'm not so sure I am. My idea of a Bluetooth stereo headset has to be extremely compact and portable. Romania-based Shepeleff Stephen's solar-fed concept, on the other hand, packs silicon panels into the headband. Translated, that means over-the-head ear cans in order to fit the solar cells where they matter. What's more, this'll have to be sizeable enough to pack two removable NiMH rechargeable batteries within the headband to store the power. Still, anything eco gets a nod for effort. And who knows, by the time something like this rolls into production, the final release may well be a lightweight futuristic strip you won't even notice.

Future air-fueled battery could store 10 times more power

A new type of air-fueled battery being studied could provide up to 10 times the energy storage of designs currently available, and someday be used to power electric cars, mobile phones, and laptops, say researchers.

"Our results so far are very encouraging and have far exceeded our expectations," said professor Peter Bruce, of the University of St Andrews' chemistry department, in a news release Monday.

The new idea the researchers are examining is to replace the lithium cobalt oxide electrode in today's rechargeable lithium batteries with a porous carbon electrode. This allows lithium-ions and electrons in the cell to react instead with oxygen in the ambient air, according to a press release from the UK's Engineering and Physical Sciences Research Council, which finances the research conducted at the University of St Andrews in Scotland. The project has received about 1.6 million British pounds (US$2.4 million) from the EPSRC.

Rubber-like display stretches definition of OLED

When it comes to a dream laptop, my biggest dilemma is that I want the machine to be as portable as possible (a.k.a. tiny), and at the same time have a huge screen. And by huge I mean 20 inches or larger.

Now it seems there's a glimpse of hope.

According to Oled-Display.net, researchers at the University of Tokyo have developed a new kind of OLED display flexible enough to stretch or deform like rubber.

The team demonstrated a face-shaped display that showed changing expressions, together with a spherical screen that displayed weather information. The researchers accomplished this by connecting OLEDs and organic transistors with a new rubbery conductor. With this, for now, they can spread the display over a curved surface without affecting its performance. The display can also be folded in half or crumpled up without incurring any damage.

This means in the future I can just fold my 30-inch LCD into a tiny square box and expand it when I need to use it. Or better yet, I'll just make a T-shirt out of it and wear it wherever I go.

Air-powered bike from India

Looks like the ultra-cheap Tata Nano made in India isn't the only vehicle that's putting the populous nation in the limelight. A group of Indian engineering students have developed a bike that putts along not on gasoline, but air. The catch: If you're in a great big rush, take the bus. The 100cc two-wheeler, running on two compressed air cylinders, won't be hurried faster than 18kmh. But at least its eco-friendly emissions won't add to the already high pollution levels in India. Not to mention that once its creators nail the speed and get it commercial, one can expect this to go the way of the Tata Nano--at a wallet-friendly price tag that should put a smile on everyone's face.
