First Generation of Batteryfree Cellphone!!!!

The battery-free phone prototype is comprised of a number of components you used to be able to buy at a Radio Shack: antennas, a power harvester to capture energy from ambient RF signals and solar cells, a microphone that listens for reflections and backscatter to record and transmit speech, a receiver, a headphone jack, a digital communication system, a small micro-controller, and a few LEDs and capacitive touch buttons for help with operating the device..

Don’t you ever felt frustrated and thought of throwing your phone away due to dying batteries in an emergency?? Here is some news, the recharging challenges with cellphones may get away from the new innovations from US.A team from the University of Washington have developed battery-free phone that can harness power from radio frequency (RF) waves sent to it from a nearby base station. The phone not only harnesses the power it needs to operate from those waves, but can also place a voice call by modifying and reflecting the same waves back to the base station, through a technique known as back scattering.

Disney’s Roomscale Wireless Charging..

Disney creates prototype living room with ubiquitous wireless power delivery

Wireless power is an idea that came into main stream ever since from 1891, when Nikola Testla demonstrated that you could transfer power between two objects via electromagnetic field. But it took over a century for the technology to find its own way, in the past few years wireless charging has finally emerged onto the consumer electronics market. But existing wireless charging is facing two challenges: range and health concerns. Safe, non-radiative methods such as near-field coupling are highly localized and require the devices to be placed near the charging source. It interrupts freedom and Charging is restricted to a confined area. Scientists at a branch of the Walt Disney Company called Disney Research have found a way to tackle these problems and charge devices on a room-scale without using any wires.

New Solid-state Battery calls for Another Battery Revolution…

A noncombustible design and can recharge in a fraction of the time of a standard battery.

Have you ever wondered what 94 year old John Goodenough, co-inventor of the lithium-ion battery, is doing?? He is hoping to find another breakthrough in battery technology. I think, he has succeded. A team of scientists under him has developed the first all-solid-state battery cells that could lead to safer, faster-charging, longer-lasting rechargeable batteries for handheld mobile devices, electric cars and stationary energy storage.

How Zero G Planes Fly???

novespace-airbusa300

If you ever wished for weightlessness like astronauts, here is an easy way to feel it… Get into a Zero Gravity Plane. Zero Gravity Planes performs parabolic arcs to create a weightless environment allowing you to float, flip and soar as if you were in space. Parabolic flight or zero gravity flight is an aerobatic maneuver performed by an airplane that enables brief (15-25 sec) periods of near-zero-gravity. Astronauts feel weightless because their space shuttle is in a state of continuous free fall to the earth. If an astronaut on the space station drops a pen, it doesn’t look like it’s falling. That’s because they’re all falling together: the pen, the astronaut and the station. But they’re not falling towards Earth, they’re falling around it. Because they’re all falling at the same rate, objects inside of the station appear to float in a state we call “zero gravity” (0g), or more accurately microgravity (1×10-6g). Objects in a state of free fall are said to be weightless. The object’s mass is the same, but it would mark “0” on a scale. Eventhough your mass stays the same, weight varies depending on whether you are on Earth, the moon or in orbit. Gravitational force is a measurement of the acceleration due to gravity that causes weight. Zero gravity is a condition of weightlessness referring to the absence of a gravitational force (g-force or Gs). Continue reading “How Zero G Planes Fly???”

New State Of Matter Is Here…

The Jahn–Teller effect, sometimes also known as Jahn–Teller distortion, describes the geometrical distortion of molecules and ions that is associated with certain electron configurations.

How many states of matter do you know about? It’s not just solids, liquids, gases, and maybe plasmas that we have to think about when we talk about the states of matter. Beyond these there’s an entire catalogue of matter alternatives: Bose–Einstein condensate, degenerate matter, supersolids/superfluids, quark-gluon plasma, etc. The difference is that all those alternatives are lab-created and don’t have much place out in the real world of nature. Researchers at Japan’s Tohoku University came up with an entirely new state of matter with an unusual combination of properties—insulator, superconductor, metal, magnet. The team, led by Kosmas Prassides, says they’ve created what’s called a Jahn-Teller metal by doping rubidium, a strange alkali metal element, into buckyballs, a pure carbon structure which has a spherical shape from a series of interlocking polygons.

Hairware

Hairware Is A New Wearable Technology That Lets You Operate Your Smartphone Via Your Hair

Don’t be surprised when a woman absentmindedly strokes her hair in public. She might be actually activating any one of her smartphone apps… Though sounds unlikely, it is possible now. A Brazilian inventor, Katia Vega, has developed an innovative new wearable gadget that allows users to discreetly control electronic devices by just stroking their hair. Continue reading “Hairware”

Fall of floating Idol of temple of konark mystery

Konark Temple is the most popular and major attraction of Konark in Orissa.

Did you know the sun temple of konark in india is one of the unique temples around the world???  Yes, it is …  because of artistic magnificence and engineering dexterity. The name Konark is derived from the words Kona – Corner and Arka – Sun; it is situated on the north eastern corner of Puri or the Chakrakshetra. The mythological reference is that Lord Krishna’s son Sambawas cured of leprosy by Sun god and he built the temple in the honour of Surya. Another story goes like this : Sun Temple of Konark, once contained a giant lodestone magnet, which held the entire edifice together by its force. This was so powerful that it used to disrupt the magnetic compass of the ships going through that route.The Portuguese removed the main magnet or lodestone as it was the cause of the destruction of lot of their ships and destroyed it. This lead to the collapse of most of the temple structure.

Six Degrees Of Separation

six degrees of separation

Six degrees of separation is the theory that anyone on the planet can be connected to any other person on the planet through a chain of acquaintances that has no more than five intermediaries. The theory was first proposed in 1929 by the Hungarian writer Frigyes Karinthy in a short story called “Chains.”Most people have heard of the “six degrees of separation” theory — the idea that everyone in the world is separated from everyone else by six links. Is it a myth or a fact of life? Continue reading “Six Degrees Of Separation”
