Motionless electromagnetic generator (MEG) The Motionless electromagnetic  generator  works on the principle of the interaction of the steady and alternating magnetic fields. This mechanism allows to  generate   free  energy from a suitable system incorporating a strong magnet in a magnetic circuit. This type of generator is called motionless because, unlike the other electromagnetic electricity generators , it contains no moving parts and has completely solid state design. This feature also leads to a very long life time. The new resonance design of this generator also can turn the overunity machine, that only has the output power higher than the input power, into an independent system with no power source. Motionless electromagnetic generator (MEG) is a very interesting and relatively easy to build type of  a free  energy generating device. In last ten years the DIY (do it yourself) prototypes of this topology of free energy genetaros appeared. For decades, the builders had to

As the point of contact between a vehicle and the road, tires are one of the most important parts of a car. Unfortunately, there's no one size fits all, or rather, one tire fits all surfaces or weather conditions, tire and swapping them over when encountering changing conditions isn't exactly feasible. Kumho has come up with a concept tire that would avoid this problem by changing its tread to suit the conditions. To pump water away from the contact patch between vehicle and road in wet conditions to prevent hydroplaning, the surface and circumference of the tire features specially-designed three-dimensional grooves. The placement of the grooves isn't just random or for show, with the design team using computer simulations to check the pattern's performance. Taking out a Platinum award in the Futuristic class on the Italian A’ Design Awards, Kumho's Maxplo tire takes the  airless tire  concept and takes things a few futuristic steps further. Rather than a fi

A new method to incorporate light-capturing nanomaterials into future solar-panel designs could make it easier for engineers to boost the efficiency and reduce the costs of photovoltaic solar cells. Although the domestic solar-energy industry grew by 34 percent in 2014, fundamental technical breakthroughs are needed if the U.S. is to meet its national goal of reducing the cost of solar electricity to 6 cents per kilowatt-hour. In a study published in Nature Communications , scientists from Rice’s Laboratory for Nanophotonics (LANP) describe a new method that solar-panel designers could use to incorporate light-capturing nanomaterials into future designs. By applying an innovative theoretical analysis to observations from a first-of-its-kind experimental setup, LANP graduate student Bob Zheng and postdoctoral research associate Alejandro Manjavacas created a methodology that solar engineers can use to determine the electricity-producing potential for any arrangement of metallic

Toyota and Hino Motors have begun testing a jointly-developed fuel cell bus in Tokyo, Japan. The brief test, which is taking place on public roads in the central and waterfront areas of the city, is designed to will help Toyota evaluate and improve the technology ahead of a possible market launch. A number of other cities around the world have either begun testing or rolling out buses that do not rely on burning fossil fuels.  London  and  Gothenburg  have seen electric buses introduced to their fleets, while hydrogen fuel cell buses were being trialled in  Hamburg  and  north-east China  as early as 2009. The Toyota-Hino bus is powered by the Toyota Fuel Cell System developed for use in the  Toyota Mirai . The system features two fuel cell stacks and motors alongside eight high-pressure hydrogen tanks that can store up to 480 l (106 gal) of hydrogen. It can produce a maximum power output of 114 kW in each of its two units. Source:  Toyota

An average 4 foot wave contains more than 35,000 horsepower per mile of coastline. US coastlines alone have the estimated potential of 23 Gigawatts. Unlike wind and solar power, power from ocean waves continues to be produced around the clock, whereas wind velocity tends to die in the morning and night, and solar is only available during the day in areas with relatively little cloud cover. Governments all across the globe are spending billions of dollars on the research of wave energy. There are many different ideas on how the world should capture this energy: Source :-  https://sites.google.com/site/kymogen/home

The thought of having needles inserted into your body may sound stressful. But to those who regularly receive acupuncture treatments, it’s quite relaxing, though scientists haven’t really been sure why. Now researchers from Georgetown University have found that needles placed at just the right parts of the body interrupt the transmission of stress hormones—the most robust evidence yet to indicate that acupuncture’s positive effects go beyond just placebo. “The benefits of acupuncture are well known by those who use it, but such proof is anecdotal. This research, the culmination of a number of studies, demonstrates how acupuncture might work in the human body to reduce stress and pain, and, potentially, depression,” said study author Ladan Eshkevari in a  press release . In  the study , published recently in the journal  Endocrinology , the researchers tested the effects of electroacupuncture, in which the needles carry a mild electric current, on stressed-out rats. They were ta

Storing solar energy as hydrogen is a promising way for developing comprehensive renewable energy systems. To accomplish this, traditional solar panels can be used to generate an electrical current that splits water molecules into oxygen and hydrogen, the latter being considered a form of solar fuel. However, the cost of producing efficient solar panels makes water-splitting technologies too expensive to commercialize. EPFL scientists have now developed a simple, unconventional method to fabricate high-quality, efficient solar panels for direct solar hydrogen production with low cost. The work is published in  Nature Communications . Many different materials have been considered for use in direct solar-to-hydrogen conversion technologies but "2-D materials" have recently been identified as promising candidates. In general these materials—which famously include graphene—have extraordinary electronic properties. However, harvesting usable amounts of solar energy requi

Back in August 2014, researchers at Michigan State University have created a fully transparent solar concentrator, which could turn any window or sheet of glass (like your smartphone’s screen) into a photovoltaic solar cell. Unlike other “transparent” solar cells that we’ve reported on in the past, this one really  is  transparent, as you can see in the photos throughout this story. According to Richard Lunt, who led the research at the time, the team is confident the transparent solar panels can be efficiently deployed in a wide range of settings, from “tall buildings with lots of windows or any kind of mobile device that demands high aesthetic quality like a phone or e-reader.” Today, Ubiquitous Energy, an  MIT startup we first reported on in 2013 , is now getting closer to bringing its transparent solar panels to market. Lunt cofounded the company and remains assistant professor of chemical engineering and materials science at Michigan State University. Essentially, what they’

New Innovations PlasticRoad features numerous advantages compared to conventional roads, both in terms of construction and maintenance. Plastic is much more sustainable and opens the door for a number of new innovations such as power generation, quiet road surfaces, heated roads and modular construction. Additionally, the PlasticRoad design features a 'hollow' space that can be used for cables, pipes and rainwater.   Prefabrication PlasticRoad's concept is in line with developments such as Cradle to Cradle and The Ocean Cleanup: the initiative to free the seas of 'plastic soup'. Recycled plastic is made into prefabricated road parts that can be installed in one piece. The prefabricated production and the lightweight design also make the construction of a PlasticRoad into a much simpler task. Roads can be built in weeks instead of months. It is also much easier to control the quality of the road (stiffness, water drainage etc.). More resistant to

Highway barriers could deliver more than just noise protection if a test currently underway in the Netherlands proves successful. The colorful roadside barriers incorporate luminescent solar concentrators (LSCs) which transfer light to conventional solar panels at the side in order to generate energy. The technology developed by Michael Debije at the Eindhoven University of Technology is being tested along the A2 highway in the Netherlands. Over the course of a year, the barriers will be tested for their effectiveness in power-generation as well as vandal-resistance and maintenance requirements. "Thanks to their many colors the LSC are visually very attractive, which makes them ideal for use in many different situations in the built environment," explains Debije. "Further benefits are that the principle used is low cost, they can be produced in any desired, regular color, is robust, and the LSCs will even work when the sky is cloudy. That means it offers tremendo
