Dipole Coil Resonance System (DCRS) The research team used the Dipole Coil Resonance System (DCRS) to induce magnetic fields,
The DCRS is composed of two (transmitting and receiving) magnetic dipole coils, placed in parallel, with each coil having a ferrite core
the dipole coil is very compact and has a less dimension. Therefore a crossed dipole structure has 2-dimension rather than 3-dimension of a crossed loop coil structure.
The DCRS has a great advantage to transfer power even when the resonance frequency changes in the range of 1%(Q factor is below 100).

The creation and control of surface plasmon wakes could lead to new types of plasmonic couplers
Surface plasmons are confined to the surface of a metal. In order to create wakes through them Capasso team designed a faster-than-light running wave of charge along a one-dimensional metamaterial like a powerboat speeding across a lake.
The metamaterial, a nanostructure of rotated slits etched into a gold film, changes the phase of the surface plasmons generated at each slit relative to each other,
increasing the velocity of the running wave. The nanostructure also acts like the boat rudder, allowing the wakes to be steered by controlling the speed of the running wave.
The team discovered that the angle of incidence of the light shining onto the metamaterial provides an additional measure of control

#Research Team Improves Lithium air batteries For Electric car Industry A research team from Carnegie mellon University and the University of California,
Berkeley, has found that blending together different types of salts in the electrolytes within lithium air batteries can increase the batteriescapacity
Lithium air batteries will soon be a strong competitor to lithium ion batteries, which currently dominate the battery-run electronics market.
Lithium air batteries are especially promising for the electric car industry, as they allow electric car battery packs to be smaller
and more lightweight and could hold more than twice as much energy as lithium ion batteries. Batteries consist of one electrode on either side an anode and a cathode and an electrolyte between them.
Lithium ion batteriescathodes typically contain heavy metal ions like manganese, cobalt or iron, but in lithium air batteries, the much lighter oxygen in a sense acts as the cathode, creating a more efficient design.
Electrolytes consist of a salt and a solvent to dissolve the salt. he electrolytes used in batteries are just like Gatorade electrolytes,
says Venkat Viswanathan, assistant professor of mechanical engineering at Carnegie mellon. very electrolyte has a solvent and a salt.
So if you take Gatorade, the solvent would be water and the salt would be something like sodium chloride, for instance.
However in a lithium air battery, the solvent is dimethoxyethane and the salt is something like lithium hexafluorophosphate. arlier this year,
a team led by Viswanathan and Assistant professor Bryan Mccloskey from the University of California, Berkeley, published a paper in Nature Chemistry,
which showed that by adding just a little bit of water into the batterieselectrolyte mixture, the researchers were able to make the lithium air batteries last four to five times longer. owever,
adding water is not a perfect solution, because it comes at the cost of being able to recharge the battery,
cautioned Viswanathan, who explained that while water increased the battery capacity, it also catalyzed additional parasitic reactions,
which prevented the batteries from being recharged. Viswanathan, Mccloskey and their colleagues Mechanical engineering Ph d. Student Vikram Pande, Abhishek Khetan, a visiting Ph d. student,
and Colin Burke, a graduate student in Mccloskey lab have published just a new paper in the Proceedings of the National Academy of Sciences,
which addresses the rechargeability problem. The paper, titled nhancing Electrochemical Intermediate Solvation through Electrolyte Anion Selection to Increase Nonaqueous Li-O2 Battery Capacity, explains that salts are the key not solvents
as they previously thought. ur original idea was to add something to the solvent dimethoxyethane,
lithium bis (trifluoromethane) sulfonimide and lithium nitrate. ande adds, y blending salts in the electrolyte solution,
we increased the battery capacity by triggering the so-called solution process without compromising on rechargeability.
Nitrate anion from the lithium nitrate salt does the trick by selectively dissolving previously insoluble products without facing the fundamental bottleneck produced by solvent additives. hough this research is an important advancement for lithium air batteries,
the methods the researchers have developed will also be very impactful in other areas of battery research. his research is going to be very important for another big battery technology,

Zell is the CEO of Nikola Labs, a startup based in Columbus, Ohio, whose energy harvesting technology was invented by Chi-Chih Chen, a research associate professor of electrical and computer engineering at Ohio State university.
Like battery pack cases, the company case plugs into the bottom of the iphone; this way, Zell says,
it can intermittently send power right to the battery. Moore Law, which predicts that the number of transistors on a chip doubles every two years,
has held steady since 1975. Yet battery technology hasn kept the same pace, probably because its evolution is dependent on advances in chemistry.
So while smartphones have gotten increasingly capable, with faster processors, better displays, and higher-resolution cameras, it can still be a challenge to get the battery that powering all these features to last throughout the day.
One way the consumer electronics industry is trying to fix this is by aligning with wireless charging technologies like Qi and Rezence.
so you can keep using your phone for battery-intensive things like looking at websites,

Made by Promethean Power systems, a company based in Pune, India, and Boston, the system keeps milk chilled with a thermal battery that stores energy and releases it,
as cooling power, over the course of a day. Like India, Bangladesh has outdated an power grid that supplies electricity sporadicallyften as little as a few hours per day.
Rural dairy farmers on the subcontinent bring their milk to village collection centers that typically rely on diesel generators, a costly, dirty way of providing electricity.
Two Americans, Sam White and Sorin Grama founded Promethean Power in 2007 to address a simple but widespread and pressing problem:
like grid power in India and Bangladesh, is by its nature intermittent, and refrigerators need constant power.
Eventually they settled on a thermal energy storage system that uses a phase-change material to store energy in the form of ice.
When the grid is operating a portion of the material freezes, and the battery circulates that thermal energy into a heat exchanger to keep milk chilled over the course of the day.
The thermal battery can store up to 28 kilowatt-hours of energy. ee not delivering new forms of energy;

how smaller batteries give more power to UK solar households When Elon musk, the chief executive of Tesla, took to the stage in California in April to launch a solar battery for the home,
the audience hollered and whooped at every detail. On the other side of the Atlantic, a more modest, quieter challenger plans to take on the US electric car giant.
The similarity lies in the product the Powervault battery which stores energy from domestic solar panels. ome people, especially if they don have solar panels,
just assume solar panels come with a battery, says Joe Warren, Powervault managing director. They don. Home energy generation has blossomed in the UK over the past four years,
with an estimated 650,000 homes fitted with solar panels. In 2010, the government introduced the feed in tariff scheme to pay householders who produce
and supply energy. The scheme aims to push renewable energy in the UK towards 15%of total energy by 2020.
In 2009, the figure stood at 2%.Powervault Tesla and other players in the emerging solar battery market aim to supply the means for householders to store energy produced during the sunniest part of the day for use at peak times,
when more people are at home but the sun is down. lot of people are not at home during the day,
they are at work, Warren says. he solar system is generating energy which is exported all. We thought,
ouldn it be great if you could store that energy and use it when you are at home in the evening?
Our system stores energy during the day when it is sunny and then gives it back to the customer in the evening.
The Powervault unit is about the size of a washing machine and weighs about 150kg (330lbs).
Inside are batteries, chargers and electronics. A charger takes the energy from the solar panels and transforms it into energy
which is stored then in the batteries and discharged around the home when needed. Powervault energy storage system is just a little smaller than the average UK washing machine. ypically the system works on a daily cycle
so it charges up when it is sunny and then on that same day discharges, Warren says. t would typically store the energy for less than 24 hours. t has a control system and a monitoring system
which works out whether you are importing or exporting electricity. If you are exporting it will charge the batteries until they are full
and if it notices that you are importing electricity, it will start to discharge energy
and reduce the amount of energy being imported from the grid by offsetting that with the energy in the battery.
The unit stores 2 to 4 kilowatt hours, enough energy to watch television for 14 or 28 hours or wash two to four full loads in the washing machine.
Priced between £2, 000 and £2, 800 per unit, it is cheaper than rivals, says Warren,
and it has been reduced in size to tailor it for The british home energy needs. he main purpose is to reduce people electricity bills,
to charge up during the day when it sunny, discharge it in the evening when people are using power.
If you made the battery bigger, you could store the energy for longer but the problem with that is it would cost a lot more.
What we have tried to do is size the unit so it is just right for a British house.
Savings from the device depend on consumption, the number of solar panels installed and how much energy they produce,
although the company estimates that it could lower electricity bills by up to 15%.%Warren said sales started in September,
with devices snapped up by early adopters and people enthusiastic about green technology. Powervault is aiming to cut the cost to £1,
000, making the savings on evolving battery technology and economies of scale. Warren says some estimates put the number of households with solar panels at 2m by 2020, by
which time the company hopes to have sold 50,000 units. hat we are trying to do here is change the electricity market,
change the way people consume energy, says Warren. he country and everybody in it are facing big challenges,
we have got huge electricity cost increases that are affecting homeowners, are affecting the country. We need to get the carbon emissions of the country down,
we need to ensure security of supply all those things affect people and affect the country as a whole.

However, competition is expected to be harsh. Tesla wall-mounted Powerwall batteries are designed to store up to 10kw hours of wind or solar energy;
units have sold out until mid-2016. It aims to have its batteries in the UK by the end of this year.
Last month, Mercedes-benz also entered the battery market for home and business use. Eco-entrepreneur Dale Vince, chair of the renewable energy firm Ecotricity,
said the home battery market remained undeveloped until now because energy had been oo cheap for too long for it to matter Ecotricity is also developing a product expected to be launched next year with a working title of lack box a 2ft to 3ft-high device that will control power coming in and out of the home.
The missing link Energy storage has been described as the missing link of solar energy adoption.
