（Researchers have developed an algorithm that allows residential customers to share power from the renewable energy sources in their homes during an outage.） If you think you can use the solar panels on your roof to power your home during an outage, think again. During an outage, while your home remains connected to the grid, the devices that manage your solar panels are powered down for safety reasons. In other words, this permanent connection to the grid makes it impossible for homeowners to draw on power generated by their own renewable energy resources. A team of engineers at the University of California San Diego wants to change this. They have developed algorithms that would allow homes to use and share power from their renewable energy sources during outages by strategically disconnecting these devices, called solar inverters, from the grid. The algorithms work with existing technology and would improve systems' reliability by 25 to 35 percent. Researchers detail the algorithms and their applications in a paper they presented at the American Control Conference in Seattle, Wash. "We were inspired to start investigating a way to use renewable power during outages after Hurricane Sandy affected eight million people on the East Coast and left some without power for up to two weeks," said Abdulelah H. Habib, a Ph.D. candidate in mechanical engineering at UC San Diego and the paper's first author. Our Society is Dependent upon ElectricityJust a few hours without power can cause massive losses to both product and revenue.We rely on electricity much more than we realize. Even if you live "off the grid," as I did for years, you are still living in a world and a society that is deeply dependent upon electricity. If the power is out for a few hours, we have all experienced that; of course you'll be fine. Maybe you will be a little bored and inconvenienced, but if the outage is lengthy and widespread, the consequences can be much more severe, even deadly. What would happen if the electricity was out for a week?Every year, 7 million customers experience power outages. Outages that last more than 5 to 10 minutes cost customers more than $80 billion each year. How the Algorithm WorksThe innovation here is the algorithm's capability to prioritize distribution of power from renewable resources during an outage. The equations take into account forecasts for solar and wind power generation as well as how much energy storage is available, including electric vehicles, batteries and so on. The algorithm combines that information with the amount of energy that the residents are projected to use as well as the amount of energy that a cluster of homes can generate.The algorithm could also be programmed to include a priority function, based on different parameters. For example, customers who are willing to pay more could get priority to get power during an outage. Or customers who generate more energy than they produce during normal operations would not lose power during an outage. More importantly, the algorithm could give priority to customers who are in urgent need of power, because they use life support equipment, for example. Ref.KY605-LC-R064R5PKY605-0860-0004

With the rapid increase in production of intermittent energy sources such as wind and solar, there is an increasing need for large-scale electrical energy storage systems to more efficiently match supply and demand for these renewable sources. Also, large-scale energy storage can increase the annual load factor (defined as the annual mean power divided by the maximum three-day mean power) by load leveling. Traditionally, pumped-hydro has been used for load leveling at large scale plants, but this is geographically limited to a small subset of locations.Flow batteries are especially attractive for these leveling and stabilization applications for electric power companies. In addition, they are also useful for electric power customers such as factories and office buildings that require increased capacities, uninterrupted supply, or backup power.And how much do you know anything about flow battery?  Flow BatteryA flow battery is a type of rechargeable battery where rechargeability is provided by two chemical components dissolved in liquids contained within the system and most commonly separated by a membrane. This technology is akin to both a fuel cell and a battery - where liquid energy sources are tapped to create electricity and are able to be recharged within the same system. One of the biggest advantages of flow batteries is that they can be almost instantly recharged by replacing the electrolyte liquid, while simultaneously recovering the spent material for re-energization. Different classes of flow cells (batteries) have been developed, including redox, hybrid and membraneless. The fundamental difference between conventional batteries and flow cells is that energy is stored as the electrode material in conventional batteries but as the electrolyte in flow cells.  A rechargeable battery to power a home from rooftop solar panelsRecently scientists have said that a rechargeable battery that could make storage of electricity from intermittent energy sources like solar and wind safe and cost-effective for both residential and commercial use. The new research builds on earlier work by members of the same team that could enable cheaper and more reliable electricity storage at the grid level. The mismatch between the availability of intermittent wind or sunshine and the variability of demand is a great obstacle to getting a large fraction of our electricity from renewable sources. This problem could be solved by a cost-effective means of storing large amounts of electrical energy for delivery over the long periods when the wind isn't blowing and the sun isn't shining. In the operation of the battery, electrons are picked up and released by compounds composed of inexpensive, earth-abundant elements (carbon, oxygen, nitrogen, hydrogen, iron and potassium) dissolved in water. The compounds are non-toxic, non-flammable, and widely available, making them safer and cheaper than other battery systems.  "This is chemistry I'd be happy to put in my basement," says Michael J. Aziz, Gene and Tracy Sykes Professor of Materials and Energy Technologies at Harvard Paulson School of Engineering and Applied Sciences (SEAS), and project Principal Investigator. "The non-toxicity and cheap, abundant materials placed in water solution mean that it's safe—it can't catch on fire—and that's huge when you're storing large amounts of electrical energy anywhere near people." This new rechargeable battery chemistry was discovered by post-doctoral fellow Michael Marshak and graduate student Kaixiang Lin working together with co-lead author Roy Gordon, Thomas Dudley Cabot Professor of Chemistry and Professor of Materials Science at Harvard. "We combined a common organic dye with an inexpensive food additive to increase our battery voltage by about 50 percent over our previous materials," says Gordon. The findings "deliver the first high-performance, non-flammable, non-toxic, non-corrosive, and low-cost chemicals for flow batteries." Unlike solid-electrode batteries, flow batteries store energy in liquids contained in external tanks, similar to fuel cells. The tanks (which set the energy capacity), as well as the electrochemical conversion hardware through which the fluids are pumped (which sets peak power capacity), can be sized independently. Since the amount of energy that can be stored can be arbitrarily increased by scaling up only the size of the tanks, larger amounts of energy can be stored at lower cost than traditional battery systems.  Application&BenefitsThe main benefits of flow batteries can be aggregated into a comprehensive value proposition.The main features that distinguish flow batteries are:  Long service life: The semi-permanent electrolyte combined with minimal electrode degradation allows for a high number of full charge-discharge cycles before replacement is needed. The electrodes do not undergo physical/chemical changes, so they can be optimized for catalytic and electrical properties without having to design for holding active substances. Also, convective cooling of the electrodes by the pumped electrolyte aids in heat distribution and management. No standby loss: During prolonged gaps in use, there is little self-discharge since the charge-carrying electrolyte is stored in separate tanks. Low maintenance: The charge state of each cell is the same since the same electrolyte is used for all cells, thus overcharging is not necessary to guarantee a uniform a charge. Recyclability & Safety: Waste vanadium can be reused and cross-contamination across the positive and negative electrode compartments does not affect the composition. Also, the electrolytes are relatively nontoxic. Charging characteristics: Redox flow batteries are "not affected by fluctuating power demand, repeated total discharge, or charge rates as high as the maximum discharge rates."  These actions severely reduce cycle life in other batteries. Modularity: Perhaps most important is that energy capacity can be scaled independently of the power; cell characteristics such as electrode area do not need to be changed to modify capacity. This allows for underground storage of electrolyte in freeform tanks, which has been demonstrated successfully in a 20 kW system. Ref.KY605-BP12-12-T2KY605-EB50-12-I2 

“For the living room, a sensual green with temperature and motion sensors.” In the future, you may be able to order that or something similar for your smart home. Sometime soon, new types of sensors could become a reality on your four walls.Science or fiction? More and more often, we find ourselves having to answer that question with science. That also applies to tiny new sensors that—hidden in wall paint—could make smart homes even smarter. On the one hand, they would have to be very, very small, and on the other, they would have to work without a battery. Researchers at the University of Eindhoven have already found an elegant solution. Their tiny temperature sensor gets its energy from the same radio waves that it uses to transmit its measuring results. First it receives radio waves from a special router via an antenna and stores it as energy. Starting at a certain energy level, it then measures the temperature and sends the results to the router. And it does so at exactly the same frequency that was chosen in advance for the measured temperature value. The router then uses the information to calculate the actual temperature. The walls have earsThe range of the tiny sensor, which measures just two square millimeters in size and weighs just 1.6 milligrams, is limited to 2.5 centimeters. But researchers hope to reach one meter during the next year. They are aiming for up to five meters in the future. Because the sensor also works under a coat of paint, pavement or concrete, there are only a few restrictions to its applications. For example, in smart homes or production environments, it could be “painted” onto the building’s walls with paint. And not just as a “thermometer”. The technology can also be used for sensors that measure motion, light and moisture. Right now the sensor stems from a 65-nm CMOS process. Produced in mass, the cost of production should come in at around 30 cents. Ref.KY45-LM35DTKY45-AMB2402

Three fingers on a new soft robotic gripper each have specialized sensors that can estimate the size and shape of an object accurately enough to identify it from a set of multiple items.  Robots have many strong suits, but delicacy traditionally hasn't been one of them. Rigid limbs and digits make it difficult for them to grasp, hold, and manipulate a range of everyday objects without dropping or crushing them. Recently, researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) have discovered that the solution may be to turn to a substance more commonly associated with new buildings and Silly Putty: silicone. At a conference this month, researchers from CSAIL Director Daniela Rus' Distributed Robotics Lab demonstrated a 3-D-printed robotic hand made out of silicone rubber that can lift and handle objects as delicate as an egg and as thin as a compact disc. Just as impressively, its three fingers have special sensors that can estimate the size and shape of an object accurately enough to identify it from a set of multiple items. "Robots are often limited in what they can do because of how hard it is to interact with objects of different sizes and materials," Rus says. "Grasping is an important step in being able to do useful tasks; with this work we set out to develop both the soft hands and the supporting control and planning systems that make dynamic grasping possible." The paper, which was co-written by Rus and graduate student Bianca Homberg, PhD candidate Robert Katzschmann, and postdoc Mehmet Dogar, will be presented at this month's International Conference on Intelligent Robots and Systems. The hard science of soft robots The gripper, which can also pick up such items as a tennis ball, a Rubik's cube and a Beanie Baby, is part of a larger body of work out of Rus' lab at CSAIL aimed at showing the value of so-called "soft robots" made of unconventional materials such as silicone, paper, and fiber. Researchers say that soft robots have a number of advantages over "hard" robots, including the ability to handle irregularly-shaped objects, squeeze into tight spaces, and readily recover from collisions. "A robot with rigid hands will have much more trouble with tasks like picking up an object," Homberg says. "This is because it has to have a good model of the object and spend a lot of time thinking about precisely how it will perform the grasp." Soft robots represent an intriguing new alternative. However, one downside to their extra flexibility (or "compliance") is that they often have difficulty accurately measuring where an object is, or even if they have successfully picked it up at all. That's where the CSAIL team's "bend sensors" come in. When the gripper hones in an object, the fingers send back location data based on their curvature. Using this data, the robot can pick up an unknown object and compare it to the existing clusters of data points that represent past objects. With just three data points from a single grasp, the robot's algorithms can distinguish between objects as similar in size as a cup and a lemonade bottle. "As a human, if you're blindfolded and you pick something up, you can feel it and still understand what it is," says Katzschmann. "We want to develop a similar skill in robots—essentially, giving them 'sight' without them actually being able to see." The team is hopeful that, with further sensor advances, the system could eventually identify dozens of distinct objects, and be programmed to interact with them differently depending on their size, shape, and function. How it works（“We want to ... give robots‘sight’ without them actually being able to see,” says MIT grad student Robert Katzschmann. ） Researchers control the gripper via a series of pistons that push pressurized air through the silicone fingers. The pistons cause little bubbles to expand in the fingers, spurring them to stretch and bend. The hand can grip using two types of grasps: "enveloping grasps," where the object is entirely contained within the gripper, and "pinch grasps," where the object is held by the tips of the fingers. Outfitted for the popular Baxter manufacturing robot, the gripper significantly outperformed Baxter's default gripper, which was unable to pick up a CD or piece of paper and was prone to completely crushing items like a soda can. Like Rus' previous robotic arm, the fingers are made of silicone rubber, which was chosen because of its qualities of being both relatively stiff, but also flexible enough to expand with the pressure from the pistons. Meanwhile, the gripper's interface and exterior finger-molds are 3-D-printed, which means the system will work on virtually any robotic platform. In the future, Rus says the team plans to put more time into improving and adding more sensors that will allow the gripper to identify a wider variety of objects. "If we want robots in human-centered environments, they need to be more adaptive and able to interact with objects whose shape and placement are not precisely known," Rus says. "Our dream is to develop a robot that, like a human, can approach an unknown object, big or small, determine its approximate shape and size, and figure out how to interface with it in one seamless motion." Ref.KY45-TSL1401CLKY45-11242-11

(A test sample comprised of a thermal chip, a heat spreader and a microcooler demonstrates the efficiency of diamond for removing heat from hotspots in semiconductor electronics.) Powerful electronic components can get very hot. When many components are combined into a single semiconductor chip, heating can become a real problem. An overheating electronic component wastes energy and is at risk of behaving unpredictably or failing altogether. Consequently, thermal management is a vital design consideration. This becomes particularly important in devices made from gallium nitride. "Gallium nitride is capable of handling high voltages, and can enable higher power capability and very large bandwidth," says Yong Han from the A*STAR Institute of Microelectronics. "But in a gallium nitride transistor chip, the heat concentrates on tiny areas, forming several hotspots." This exacerbates the heating problem. Han and co-workers demonstrate both experimentally and numerically that a layer of diamond can spread heat and improve the thermal performance of gallium nitride devices. The researchers created a thermal test chip that contained eight tiny hotspots, each 0.45 by 0.3 millimeters in size, to generate the heat created in actual devices. They bonded this chip to a layer of high quality diamond fabricated using a technique called chemical vapor deposition. The diamond heat spreader and test chip were connected using a thermal compression bonding process. This was then connected to a microcooler, a device consisting of a series of micrometer-wide channels and a micro-jet impingement array. Water impinges on the heat source wall, and then passes through the micro-channels to remove the heat and keep the structure cool. Han and the team tried their device by generating 10–120 Watts of heating power in test chips of 100 and 200-micrometer thickness. To dissipate the heating power, the diamond heat spreading layer and microcooler helped maintain the structure at a temperature below 160 degrees Celsius. In fact, the maximum chip temperature was 27.3 per cent lower than another device using copper as the heat spreading layer, and over 40 per cent lower than in a device with no spreading layer. The experimental results were further confirmed by thermal simulations. The simulations also indicated that the performance could be improved further by increasing the thickness of the diamond layer, and that good bonding quality between the gallium nitride chip and the diamond heat spreader was crucial to obtain the best performance. "We next hope to develop a novel micro-fluid cooler of higher and more uniform cooling capability, and to achieve thermal management using a diamond layer of high thermal conductivity near an electronic gate," says Han. Ref.KY56-MJL4302AKY56-PZTA06KY56-FZT958TA
