Wireless electricity?Really!!!

What's the trick? "We're going to transfer power without any kind of wires," says Dr Hall, now Chief Technology Officer at WiTricity, a startup developing wireless "resonance" technology. "But, we're not actually putting electricity in the air. What we're doing is putting a magnetic field in the air." It works like this: WiTricity builds a "Source Resonator," a coil of electrical wire that generates a magnetic field when power is attached. If another coil is brought close, an electrical charge can be generated in it. No wires required. "When you bring a device into that magnetic...

HOUSE THAT WALKS

A House That  Walks:-                                                                     Don't want to leave home than take home with you....  Houses are normally fairly stationary objects, and that's not considered a bad thing. But innovation never stands still, and a new prototype house that can walk on six legs has been built . The house is ten feet high, powered by solar panels, and is outfitted with a kitchen,...

3D - PEN

Three Dimensional Printing :-                                                                               Who says we can't write in air  Inventors Max Bogue and Peter Dilworth have invented a unique pen that draws in the air. A colorful spool of plastic thread is fed into the pen. The thread is then extruded as heated plastic that cools and solidifies instantly as it exits the tip. This allows...

ROBO-BEE

Fly-sized Robot Takes First Flight Flies have tiny wings and even tinier brains, yet they are capable of flying swiftly and agilely through even turbulent air. How do they do it? And could we create a robot capable of doing the same? That's the question that's been buzzing around Harvard professor Robert Wood's head for 12 years now. And finally, after years of testing and the invention of an all-new manufacturing technique inspired by children's pop-up books, Wood and his team at the Wyss Institute for Biologically Inspired Engineering at Harvard University have created a robot the size...

Kill The Need For Flash In Camera

New Camera Sensor Eliminates Need for Flash No flash? No problem. A new imaging sensor could soon make it possible for photographers to take clear, sharp photos, even in dim lighting. Created by a team of researchers at Nanyang Technological University (NTU) in Singapore, the new sensor is highly sensitive to both visible and infrared light, which means it could be used in everything from the family Nikon to surveillance and satellite cameras.  The sensor, which is 1,000 times more sensitive to light than the imaging sensors of most of today's cameras, gets this high photoresponse...

INVISIBLE CAR

'Invisible' Mercedes car Everyone from Harry Potter has already got an invisibility cloak.  But scientists have now figured out how to make an entire car disappear.  Using optical camouflage technology boffins at Mercedes Benz created the illusion that their new zero emissions F-Cell car is not even there at all.  Taking the principal that to see through something you need to see what's behind it, they covered the driver's side of the car in mats of LEDs, and mounted a digital SLR camera on the opposite side of the vehicle. The camera shoots video...

SEE THROUGH WALLS

Researchers See Through Walls With 'WiVi' Want X­ray vision like the man of steel?    A technology that lets you see behind walls could soon be built in to your cell phone. MIT professor Dina Katabi and graduate student Fadel Adib have announced Wi­Vi, a demonstration of a technology that uses Wifi to allow a viewer to "see" a person moving behind a wall. (Wi­Vi stands for "Wi­Fi" and "vision.") Previous work demonstrated that the subtle reflections of wireless inter signals bouncing off a human could be used to track that person's movements, but those previous experiments...
