Wowhoo Wireless Phone Charger: the uniqueness and the features
Major wireless phone carriers have all been adapting the Qi wireless technology. Additionally many car manufactures are adding them to their 2014-2015 models. Manufactures include but are not limited to the following: Jeep, Toyota, Prius Harrier, Mercedes Benz, BMW, Volkswagen, Audi aswell as Porsche.
Due to the new and improved design and usability our initial launch date has been revised from Jan 7th to March 1st. we added approximately 8mm to our diameter to allow a better internal design. The small revision to the Wowhoo charger allow us to get that quicker charge which is most important. The 10% is a big jump in charging speed.
More than half of all personal aircraft accidents occur during takeoffs or landings. That’s why inventor and entrepreneur JoeBen Bevirt—known for designing airplane-like wind energy turbines—is intent on making runways obsolete. Bevirt, 40, has mobilized his wind energy team to create a personal electric airplane called S2 that takes off vertically, like a helicopter, and flies aerodynamically, like an airplane.

No full-scale prototype exists yet, but Bevirt and his team have built about two dozen 10-pound models to demonstrate their concept works. NASA has taken notice and is now funding the development of a 55-pound unmanned aerial vehicle. Supercomputer simulations of a full-scale, 1,700-pound S2 suggest it could fly two people about 200 miles (New York City to Boston) in an hour on 50 kilowatt-hours of electricity, or roughly equivalent to 1.5 gallons of fuel used by a typical two-seat airplane—which would make the new aircraft about five times more efficient.
Retractable arms reposition the motors to transition between vertical takeoff, forward flight, and landing.

Fusion energy almost sounds too good to be true — zero greenhouse gas emissions, no long-lived radioactive waste, a nearly unlimited fuel supply.
Perhaps the biggest roadblock to adopting fusion energy is that the economics haven’t penciled out. Fusion power designs aren’t cheap enough to outperform systems that use fossil fuels such as coal and natural gas.IJSRD is a leading e-journal, under which we are encouraging and exploring newer ideas of current trends in Engineering and Science by publishing papers containing pure knowledge.
University of Washington engineers hope to change that. They have designed a concept for a fusion reactor that, when scaled up to the size of a large electrical power plant, would rival costs for a new coal-fired plant with similar electrical output.
The team published its reactor design and cost-analysis findings last spring and will present results Oct. 17 at the International Atomic Energy Agency’s Fusion Energy Conference in St. Petersburg, Russia.
“Right now, this design has the greatest potential of producing economical fusion power of any current concept,” said Thomas Jarboe, a UW professor of aeronautics and astronautics and an adjunct professor in physics.
The UW’s reactor, called the dynomak, started as a class project taught by Jarboe two years ago. After the class ended, Jarboe and doctoral student Derek Sutherland — who previously worked on a reactor design at the Massachusetts Institute of Technology — continued to develop and refine the concept.
The design builds on existing technology and creates a magnetic field within a closed space to hold plasma in place long enough for fusion to occur, allowing the hot plasma to react and burn. The reactor itself would be largely self-sustaining, meaning it would continuously heat the plasma to maintain thermonuclear conditions. Heat generated from the reactor would heat up a coolant that is used to spin a turbine and generate electricity, similar to how a typical power reactor works.
“This is a much more elegant solution because the medium in which you generate fusion is the medium in which you’re also driving all the current required to confine it,” Sutherland said.
There are several ways to create a magnetic field, which is crucial to keeping a fusion reactor going. The UW’s design is known as a spheromak, meaning it generates the majority of magnetic fields by driving electrical currents into the plasma itself. This reduces the amount of required materials and actually allows researchers to shrink the overall size of the reactor.
Other designs, such as the experimental fusion reactor project that’s currently being built in France — called Iter — have to be much larger than the UW’s because they rely on superconducting coils that circle around the outside of the device to provide a similar magnetic field. When compared with the fusion reactor concept in France, the UW’s is much less expensive — roughly one-tenth the cost of Iter — while producing five times the amount of energy.
The UW researchers factored the cost of building a fusion reactor power plant using their design and compared that with building a coal power plant. They used a metric called “overnight capital costs,” which includes all costs, particularly startup infrastructure fees. A fusion power plant producing 1 gigawatt (1 billion watts) of power would cost $2.7 billion, while a coal plant of the same output would cost $2.8 billion, according to their analysis.
“If we do invest in this type of fusion, we could be rewarded because the commercial reactor unit already looks economical,” Sutherland said. “It’s very exciting.”
Right now, the UW’s concept is about one-tenth the size and power output of a final product, which is still years away. The researchers have successfully tested the prototype’s ability to sustain a plasma efficiently, and as they further develop and expand the size of the device they can ramp up to higher-temperature plasma and get significant fusion power output.
The team has filed patents on the reactor concept with the UW’s Center for Commercialization and plans to continue developing and scaling up its prototypes.
Other members of the UW design team include Kyle Morgan of physics; Eric Lavine, Michal Hughes, George Marklin, Chris Hansen, Brian Victor, Michael Pfaff, and Aaron Hossack of aeronautics and astronautics; Brian Nelson of electrical engineering; and, Yu Kamikawa and Phillip Andrist formerly of the UW.
The research was funded by the U.S. Department of Energy.

EU-funded researchers are demonstrating revolutionary robotic techniques inspired by plants, featuring a 3D-printed ‘trunk’, ‘leaves’ that sense the environment and ‘roots’ that grow and change direction.
Lets Research !!! DO IT >>>> IJSRD
Humans naturally understand problems and solutions from an animal’s perspective, tending to see plants as passive organisms that don’t ‘do’ much of anything, but plants do move, and they sense, and they do so in extremely efficient ways.
Barbara Mazzolai of the Istituto Italiano di Tecnologia (IIT) coordinates the FP7 — PLANTOID project, funded via the Future and Emerging Technologies (FET) scheme. She says humans can learn a lot from plants. ‘Our aim is to design, prototype and validate a new generation of ICT hardware and software technologies inspired by plants.’ And she sees potential applications for such technologies in agriculture, medicine and even space exploration.
The PLANTOID prototype was designed with two functional roots: one root demonstrates bending capabilities, responding to input from the sensors at the tip of the root. This way the root is bending away from a stumbling block or aggressive or toxic products. A second root demonstrates artificial growth. ‘Layers of new material are deposited near the tip of the root to produce a motive force, penetrating the soil,’ Mazzolai explains. Practically, the robot grows by building its own structure and penetrates the soil.
The roots are connected to a trunk housing a micro-computer. The trunk itself is made of plastic and was produced using a 3D printer. Finally, just like natural leaves, the ‘leaves’ of the PLANTOID robot include sensors that can assess environmental conditions, including temperature, humidity, gravity, touch, and chemical factors.
Unique design exploiting unique plant properties
Backed by EUR 1.6 million of EU funding, the PLANTOID project is the first to design and develop robotic solutions based on plant models. The prototype is not meant to serve a particular application as such, but represents a demonstration of new robotic techniques. However, Mazzolai says real-life applications in the future could include detection and assessment of pollutant concentrations, e.g. heavy metals, or nutrients in the environment, as well as mapping and monitoring of conditions in terrestrial soils.
Indeed, plant-like robots could be uniquely suited to space exploration, able to dig and implant themselves on alien worlds, following sensory leads while adapting to potentially harsh external conditions.
Other promising applications could include flexible endoscopic robots for delicate surgical applications in the medical field, while larger plant-like robots could be of use in search and rescue operations, for example after a natural disaster.
‘Plants are very efficient in terms of their energy consumption during motion,’ says Mazzolai, ‘and this suggests many approaches that are muscle-free and thus not necessarily animal-like for the world of robotics.’ Indeed, the unique characteristics of plants could become a source of inspiration for new companies that can produce smart and useful plant-like robotic devices.
2014′s Nobel Prize for Physiology or Medicine has been awarded to John O’Keefe, May-Britt Moser, and Edvard Moser for their discovery of the brain’s “inner GPS” system. The prize revolves around their discovery of place cells and grid cells — special neurons in the hippocampus and entorhinal cortex of animals (including humans, monkeys, and rats) that appear to create a cognitive map of every room or space that you’ve ever explored. As you move around a room or space, a very specific place cell fires — and when you visit the same place again in the future, the same place cell fires every time. The three researchers will share a $1.1 million prize.
Back in 1971, O’Keefe and Jonathan Dostrovsky discovered that the rat hippocampus had special place cells that, as their name suggests, are specifically involved with the rat’s current place. Prior to 1971 we already knew that the hippocampus was deeply involved with memory and learning, but the specificity of place cells and the cognitive spatial map they constructed was groundbreaking work. Later work has shown that there really are specific pyramidal neurons that fire in a certain pattern when an animal (rat, human, etc.) is in a specific place.#IJSRD #Research. . . ! ! !

If you stop and think about it for a moment, you will realise what an astonishing feat of precision engineering your colour printer is. It can take the primary colours – cyan, yellow, magenta and black – and mix them together carefully enough to achieve more than a million different hues and shades. Not only that but the drops of colour are mere nanolitres (billionths of a litre) in volume, each of which is then placed on the paper – assuming its not jammed in the feeder tray – with better than pinpoint accuracy.
Now a group of enterprising chemists from Tsinghua University are exploiting that precision engineering, which normally results in high-resolution colour prints, to screen millions of different chemical reactions. Their results have been published in the journal Chemical Communications.

One of the most popular terms that seems to be popping up on every technology site nowadays is big data. I think the industry is doing a disservice with its overuse and the inaccurate picture it depicts of what’s really happening.
“Big data is a buzzword, or catch-phrase, used to describe a massive volume of both structured and unstructured data that is so large that it’s difficult to process using traditional database and software techniques.” According to Webopedia
The problem is that big data is not just a big database. Big data is basically a 2-dimensional description. The problem is that companies are not just battling large databases, they’re battling the velocity of the data. Giant streams of data are coming in real-time that have to be normalized and presented in a way that provides an analysis of what’s occurring over time.
I believe a more accurate depiction might be streaming data. Streaming data has both the promise of finding nuggets of information that marketers can capitalize on, as well as real-time, trending and predictive analysis that can provide marketers with opportunities to adjust their strategy to maximize results. Systems have to normalize, archive, present and predict for us to truly capitalize on the massive data streams that are available.
Don’t be fooled by the marketing speak surrounding big data. The solutions are already present to process massive volumes of data. Tapping streaming data is what we’re really in need of.

Abstract—Many significant weather events have affected our life over the years. Today, the temperature, wind and other weather parameters are of equal concern and can have an even greater impact on our high-tech life style. Weather affects a wide range of man’s activities. This can cause the movement of gases through the atmosphere. Also, in an industry during certain mishap it is very difficult to monitor the parameters through wires and analog devices. So to overcome this problem we can use wireless device to monitor the parameters. By monitoring this parameters we can take certain steps in worst cases. In this weather station monitoring systems, different parameters like temperature, light, humidity, wind direction and speed, gas level are all sensed using sensors.
