Citation: Salt and Paper Battery May One Day Replace Lithium Batteries (2009, September 15) retrieved 18 August 2019 from https://phys.org/news/2009-09-salt-paper-battery-day-lithium.html A new thin-film battery has electrodes made of polymer-coated paper and an electrolyte made of salt-soaked paper. A laboratory prototype shows the cell pressed between glass slides and packaged in an aluminum pouch. Credit: Maria Stromme, Uppsala University At Uppsala University in Sweden, researchers have developed a flexible battery made of two inexpensive materials: cellulose and salt. The cellulose is derived from a polluting algae found in seas and lakes. The algae’s walls contain cellulose that has a different nanostructure, which gives it 100 times the surface area. The battery is made by coating the paper, made from this cellulose, with a conducting polymer and inserting a salt-solution-soaked filter paper between the paper electrodes. Chlorine ions travel from the batteries positive terminal to the negative terminal while current is produced in the external circuit by the flow of electrons. The battery can be recharged in tens of seconds because the ions flow through the thin electrode quickly. In comparison to a lithium battery that would take 20 minutes to recharge. The salt and paper battery is still in the early stages of development as compared to other thin-film technologies. For a battery to be cost effective you need to able to obtain the material at relatively low cost and have a good manufacture process in place.The battery could be produced commercially in about three years and made available to distributors.Via: RSC and Technology Review© 2009 PhysOrg.com Nanoball Batteries Could Charge Electric Cars in 5 Minutes (PhysOrg.com) — Salt and paper battery can be used in many low-power devices, such as medical implants, RFID tags, wireless sensors and smart cards. This battery uses a thin-film which makes it an attractive feature for many portable devices that draws a low current. Explore further This document is subject to copyright.

(PhysOrg.com) — Mouseless is a computer mouse that allows you to interact with a computer with a mouse in the same way as usual – except that there is no mouse hardware. The researchers call it an “invisible mouse.” The MIT Media Lab’s Fluid Interfaces group works on ways of integrating the world of digital information and services more naturally into our normal lives, by designing intuitive and intelligent interfaces. Pranav Mistry is a PhD student and research assistant at MIT Media Lab. His project “SixthSense” won the Popular Science Invention of the Year award in 2009.• Learn about becoming PhysOrg.com sponsor Mouseless is an invisible computer mouse. There are no plans for commercializing the “invisible mouse,” but the prototype Mouseless was built for around $20 USD. The MIT group of researchers are now working on improvements to the recognition and tracking algorithms with the aim of building up an expanded command library. This may in the future lead to more complex gesture recognition than is possible at present, and could ultimately give the Mouseless a number of advantages over a physical mouse, since the number of functions handled by a physical mouse is limited. More information: www.pranavmistry.com/projects/mouseless/ Explore further A group of scientists working with the Fluid Interfaces Group at the Massachusetts Institute of Technology (MIT) Media Lab in Cambridge Massachusetts, were interested in removing the requirement for a physical mouse, while still allowing computer users to interact with their computers in a way with which they were familiar. The researchers, Pranav Mistry, Liyan Chang, and Pattie Maes, developed an infrared (IR) laser beam and associated camera that could be incorporated into the computer so that a plane of IR laser would be created just above the surface on which the computer is resting. The user acts as though a physical mouse were present and the laser beam is intersected by the hand, and parts of the hand are shown up as bright spots of light that change position as the hand moves. The built-in camera then interprets the changes in position of the hand and fingers and translates them as moves of the mouse and clicks on the two buttons, and the cursor on the screen moves as if the user was operating a physical mouse. © 2010 PhysOrg.com Movea’s Gyration Air Mouse Mouseless working prototype system Citation: Mouseless, the ‘invisible’ computer mouse (w/ Video) (2010, July 8) retrieved 18 August 2019 from https://phys.org/news/2010-07-mouseless-invisible-mouse-video.html This document is subject to copyright.

Once installed, an initial test run of the system will commence to ensure all of the parts are working correctly. Once that is completed, the two busses will run their normal bus routes (with passengers) for 12 months, during which time researchers from the Karlsruhe Institute of Technology will be analyzing data from the system to monitor, tweak and build a knowledge base of information to be used in building future test sites to optimize the system overall.An inductive charging system is wireless; current is passed through the air—in this case from beneath the roadbed to components installed in the undercarriage of a bus. For such a charging system to work as part of a bus line, the right size batteries must be used. Ideally, small batters can be employed as they will be given frequent charges—this allows for increased efficiency due to a lighter battery load. The batteries must be just large enough to ensure a bus can complete its route each day without ever having to stop for just recharging purposes. In addition to providing a city with zero emissions (at the point of use), electric busses also reduce noise pollution. As part of testing the system, researchers will also be speaking directly with passengers to get their ideas on how well the busses work within the system.The German government has stated its intent to pursue electric technology for busses in the country and has backed up that pledge by offering funds to various projects. For this test, the country’s Federal Ministry of Transport, Building and Urban Development will be footing the bill to the tune of €3.3 million (US$4.35 million).

(Phys.org)—When a giant cloud of molecular gas condenses, star clusters are born. It may sound simple but the formation of star clusters is a very complex process, not yet completely understood by scientists. By peering into this process we could get valuable information on the evolution of galaxies and improve our knowledge about large cosmic structures in the universe.

Understanding how these objects form and evolve is vital to our comprehension of the structure, formation and evolution of galaxies,” Denilso Camargo of the Federal University of Rio Grande do Sul and Colégio Militar de Porto Alegre, Brazil, told Phys.org.Camargo and his colleagues Eduardo Bica and Charles Bonatto, also from the Federal University of Rio Grande do Sul, have recently discovered a multitude of star clusters using NASA’s Wide-field Infrared Survey Explorer. In a paper published online on Nov. 9 on ArXiv, they announced the finding of 652 star clusters, stellar groups and candidates in the Milky Way galaxy.The researchers targeted 862 objects for observations by WISE. They were looking for dust emission nebulae followed by a search for stellar overdensities within them. What they found is a variety of interesting objects classified as open clusters (OCs), open cluster candidates (OCCs), embedded clusters (ECs), embedded cluster candidates (ECCs), and embedded stellar groups (EGrs).There are two main groups of star clusters: OCs and globular clusters (GCs). OCs are generally young objects, up to a few tens of millions of years old. They are much less densely populated and much less tightly gravitationally bound than GCs. In contrast to OCs, globular clusters are tight groups of very old stars, distributed roughly spherically in the galactic halo, around the galactic center. They have highly elliptical orbits around the galactic center, while OCs are usually located in the galactic plane, almost always within spiral arms.ECs are also intriguing and peculiar stellar clusters. They are partially or fully encased in interstellar dust or gas. They consist of extremely young, recently formed or forming stars. For scientists, they are important laboratories for the study of star formation and early stellar evolution.Camargo noted that the diversity of star clusters comes in handy when dealing with questions still baffling astronomers.”The open cluster system has been used to analyze the structure, dynamics, composition and evolution of the Milky Way’s disk. Old open clusters are excellent probes of disk formation and early evolution. Young open clusters have been used as tracers of the spiral pattern in galactic disks,” Camargo said.He added that his team recently used embedded clusters to trace the spiral structure of our Galaxy. The results favor a four-armed spiral pattern for the Milky Way.Studying star clusters is a fundamental task for researchers when it comes to unlock the secrets of star formation process, as most stars, if not all, form in star clusters. Moreover, the chemical evolution of the universe is directly related to stellar evolution in the sense that metals currently observed are synthesized in the interior of the stars, which are born within star clusters.The research team led by Camargo has a stunning record of 1098 star clusters found so far. The newest list is a follow-up of the 446 previous discoveries detailed in three other papers. More information: Characterizing star cluster formation with WISE: 652 newly found star clusters and candidates, arXiv:1511.01978 [astro-ph.GA] arxiv.org/abs/1511.01978AbstractWe report the discovery of 652 star clusters, stellar groups and candidates in the Milky Way with WISE. Most of the objects are projected close to Galactic Plane and are embedded clusters. The present sample complements a similar study (Paper I) which provided 437 star clusters and alike. We find evidence that star formation processes span a wide range of sizes, from populous dense clusters to small compact embedded ones, sparse stellar groups or in relative isolation. The present list indicates multiple stellar generations during the embedded phase, with giant molecular clouds collapsing into several clumps composing an embedded cluster aggregate. We investigate the field star decontaminated Colour Magnitude Diagrams and Radial Density Profiles of 9 cluster candidates in the list, and derive their parameters, confirming them as embedded clusters.

E-Liquids are usually comprised of glycerin and propylene glycol along with a flavor additive. Glycerin, when heated, predominantly forms acrolein and formaldehyde, while propylene glycol predominantly forms acetone and acetaldehyde. Certain flavor additives have shown enhanced aldehyde formation, as well. Citation: Quantitative study of aldehyde content in electronic cigarettes (2017, April 17) retrieved 18 August 2019 from https://phys.org/news/2017-04-quantitative-aldehyde-content-electronic-cigarettes.html Credit: CC0 Public Domain Ogunwale et al. used a microreactor-capture approach that they had previously developed to obtain an accurate look at aldehyde levels in e-cigarette vapor. This method employs a 4-(2-aminooxyethyl)-morpholin-4-ium chloride (AMAH) coating on a silicon base. Aldehydes selectively react with AMAH to form an oxime, which is more stable and easier to study than an aldehyde.Aerosols were generated using a cigarette-smoking robot and were collected in Tedlar bags. The robot allowed for control over puff duration, puff volume, and puff frequency. The aerosols flowed through the microreactors from the bags using an evacuation process and then reacted with AMAH. The AMAH oxime compound was neutralized to form an AMA adduct that was then studied using gas chromatography.Both the first generation and next generation e-cigarettes produced some amount of acetaldehyde, acrolein, and formaldehyde, but acealdehyde and formaldehyde were in higher concentrations than acrolein. All of the aldehydes were present in lower concentrations than what is found in cigarette smoke using Health Canada Intense Puffing Regime. Notably, the next-generation e-cigarettes, which have a tank-type atomizer, produced higher levels of aldehydes and acetone. The authors attribute this to the higher battery output.To understand the puffing topology, Ogunwale et al., used 60-mL syringes to manually vary puff duration and volume to more accurately replicate real-life usage. Puffing duration and the particular flavor contributed to the formation of reactive aldehydes, although these factors played a smaller role than battery output in the amount of aldehydes present. If puffing duration was around 4.0 seconds/puff, more aldehydes were present compared to shorter or longer puffing. The average user puffs for 3.5 to 4.3 seconds.Finally, Ogunwale et al. used 1H NMR to detect and quantify the presence of hemiacetals formed from aldehydes. They found that hemiacetals did not form in any of the first-generation e-cigarettes flavors, and they did not form in three of the next-generation flavors tested. Only one flavor that was tested formed hemiacetals within a battery output that was within the range of normal use. This study provides valuable information on the safety of e-cigarettes. In general, the higher the battery output, the higher the aldehyde levels in the vapor. Certain aldehydes, such as acrolein, acetaldehyde, and formaldehyde, have been shown to contribute to CVD even in low levels. All of the e-cigarettes tested in this study had some amount of these aldehydes present. Hazardous chemicals discovered in flavored e-cigarette vapor More information: Mumiye A. Ogunwale et al. Aldehyde Detection in Electronic Cigarette Aerosols, ACS Omega (2017). DOI: 10.1021/acsomega.6b00489AbstractAcetaldehyde, acrolein, and formaldehyde are the principal toxic aldehydes present in cigarette smoke and contribute to the risk of cardiovascular disease and noncancerous pulmonary disease. The rapid growth of the use of electronic cigarettes (e-cigarettes) has raised concerns over emissions of these harmful aldehydes. This work determines emissions of these aldehydes in both free and bound (aldehyde–hemiacetal) forms and other carbonyls from the use of e-cigarettes. A novel silicon microreactor with a coating phase of 4-(2-aminooxyethyl)-morpholin-4-ium chloride (AMAH) was used to trap carbonyl compounds in the aerosols of e-cigarettes via oximation reactions. AMAH–aldehyde adducts were measured using gas chromatography–mass spectrometry. 1H nuclear magnetic resonance spectroscopy was used to analyze hemiacetals in the aerosols. These aldehydes were detected in the aerosols of all e-cigarettes. Newer-generation e-cigarette devices generated more aldehydes than the first-generation e-cigarettes because of higher battery power output. Formaldehyde–hemiacetal was detected in the aerosols generated from some e-liquids using the newer e-cigarette devices at a battery power output of 11.7 W and above. The emission of these aldehydes from all e-cigarettes, especially higher levels of aldehydes from the newer-generation e-cigarette devices, indicates the risk of using e-cigarettes.

Many people believe that they are healthier than cigarettes, but others say that the effects of e-cigarette vapors are largely unknown. Medical organizations have generally taken a cautious approach and do not specifically recommend e-cigarettes for stopping smoking or as a healthier alternative to smoking. © 2017 Phys.org One area of concern is the amount of aldehydes present in e-cigarette smoke. These aldehydes are present in tobacco cigarettes in larger quantities than in e-cigarettes, but the levels in e-cigarettes are still not known. Additionally, the amount that is considered dangerous for cardio vascular disease (CVD) is a topic of debate. Some studies have shown that even small amounts of certain aldehydes can lead to progression of CVD.Researchers from the University of Louisville’s Tobacco Regulation and Addiction Center conducted quantitative analyses of both older (first generation) and newer-model e-cigarette cartridges using a variety of flavors. They used a new method for trapping reactive carbonyls that are then subsequently stabilized using an oximation reaction. They found that newer devices produced more harmful aldehydes than first generation e-cigarettes. Their work appears in ACS Omega.E-cigarettes cartridges contain battery-powered coils that serve to heat and vaporize e-Liquid. Based on this study, the amount of reactive aldehydes in e-cigarette vapor are largely due to the cartridge’s battery power. The higher the battery power, the higher the aldehyde levels. While e-cigarette aerosols contain aldehydes that are known to contribute to CVD, the exact levels have not been definitively determined largely because of the difficulties associated with trapping and studying reactive aldehydes. New models, or “next-generation,” e-cigarettes have a higher battery power than older ones. Furthermore, older models have a fixed battery output (4.6 W) while the next-generation ones have variable output (9.1 W, 11.7 W, 14.7 W, 16.6 W). The authors wanted to look at this next-generation of e-cigarettes to quantitatively determine aldehyde levels as well as determine if e-Liquid flavor makes a difference in aldehyde formation. In order to do this, they took into account the formation of hemiacetals from aldehydes, something that prior studies did not address.The aldehydes that are of greatest concern are acetaldehyde, acrolein, and formaldehyde. Acrolein, in particular, has been shown to advance CVD, even when a person is exposed to low levels. Formaldehyde has also been associated with CVD in low concentrations. Explore further
© 2018 Phys.org Explore further The Shigir Idol was discovered in an ancient peat bog by miners in Russia back in 1890. Early analysis showed that it was made entirely of larch wood and was constructed from several chunks. It remained preserved for thousands of years because of antimicrobial properties found in the peat. The idol was also covered extensively with markings, some of which depicted tiny human faces. To this day, no one knows what most of the markings depict. It was also noted that some of the original pieces of the idol had been lost—it is believed that it originally stood approximately five meters tall. In 1997, a team in Russia used radiocarbon dating to estimate the age of the icon and found it to be approximately 9,500 years old.Experts have studied the carvings on the idol over the years, and many have suggested they likely represent a form of art, possibly linked with spiritual or religious activities.Recently, the team in Germany expressed interest it taking a closer look at the idol, which is normally housed in the Sverdlovsk Regional Museum, in Russia. Arrangements were made for the idol to be shipped to Germany, where it was studied, along with other original material found in the peat bog. Using accelerator mass spectrometry, the team found the true age of the idol to be approximately 11,500 years old, placing its creation at around the time of the end of the Ice Age. That age also makes it the oldest known wood monumental sculpture ever found and more than twice the age of the Egyptian pyramids. The researchers report that they also found another face carved into the wood, bringing the total to eight. Their findings suggest that researchers looking to better understand very early human behavior perhaps need to widen their search beyond the Fertile Crescent.

My father advised me to look through all the photos on the internet about the history of Russia, whatever I could find. Then we were given a few books and started painting. By that time, I realised that I had the feeling that Russia was famous for snow and its winter. Many people also told me that winter in Russia was amazing. And the architecture is something magnificent.’
National Museum Institute took a major stride in realising an independent campus for the 25-year-old educational centre when Union Minister of State for Culture and Tourism, Mahesh Sharma laid the foundation stone of the institute at a three-acre plot in Noida on January 31.The National Museum Institute of History of Art, Conservation and Museology (NMI) will get a five-storeyed complex in its new premises at Sector 62 in 30 months with an estimated expenditure of Rs 90 crore, thus set to become a one-of-its-kind national resource centre for post-graduate and doctoral studies in art and heritage. “The institute will be a milestone in the future history of Noida and also for the country,” the minister said after unveiling the plaque at the function.Sharma noted that the eco-friendly institute with hostel facilities would generate more jobs and invigorate heritage upkeep in India. The 1989-founded NMI currently functions at National Museum premises in Delhi. Vasudevan said, “The institute will provide five post-graduate courses on Art history, Conservation and Museology. There will also be short-term courses for imparting of certain skills associated with the field,” he added.

But there are enough seats for students. Hence, we took the decision to extend the admission deadline,” he said. In the past, too, Chatterjee had said students should not crowd a few educational institutions for admission. Asked about his response to the reintroduction of admission tests in Jadavpur University, Chatterjee said, “It (JU) is an autonomous institution. The government won’t interfere in its functioning.” The JU had recently witnessed a hunger strike by students in protest against the decision of the authorities to scrap admission test in six subjects. The university, after holding its ground for almost a week, buckled under the pressure of students and reintroduced entrance tests. The entrance tests in the six arts subjects will be conducted in the last week of July.
Kolkata: The Directorate of Revenue Intelligence (DRI) has detected a huge duty evasion by a company here in the import of e-rickshaws worth around Rs 150 crore and arrested two promoters of the firm, according to an official statement issued today. The Kolkata-based firm has imported ‘Electric-Three-Wheeled Vehicles (E-Rickshaws)’ commonly known as ‘Toto’ in completely knocked down (CKD) condition, by “grossly misdeclaring” goods as ‘spare parts of electric tricycle’, it said. Also Read – Rain batters Kolkata, cripples normal life The importer paid 10 per cent customs duty leviable on such parts, whereas, they had actually been importing electric tricycles in CKD condition, with pre-assembled transmission mechanism, which attract the much higher rate of 30 per cent customs duty, the statement said. Their omission and commission have resulted in short-payment of customs duty to the extent of Rs 19 crore on the import of e-rickshaws in the last four years valued at approximately Rs 150 crore, it said. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killed “Therefore, taking into consideration the present as well as the past imports made by the said importer, by resorting to such gross misdeclaration, the short-payment of duty comes to the extent of Rs 19 crores,” the statement said. The importer actually imported complete e-rickshaws (Toto) in completely knocked down (CKD) condition, which were split over a number of consignments, it said. As the individual consignment did not contain all parts of an e-rickshaw, they claimed benefit of exemption by declaring such goods as parts and spares of electrical tricycle, the DRI said. “When collectively considered, it is seen that sets of E-rickshaws were imported in CKD condition, but the importer by deliberately misclassifying the same as parts/spares of electrical tricycle, paid customs duty only at the rate of 10 per cent, resulting in evasion of huge amount of customs duty,” it said. DRI officials searched the premises known to be the ‘factory’ of the firm at Sankrail industrial park at Mouza Bhagabatipur in Howrah. “During a search of the factory premises, it was found that in the entire facility, they had only a few machines and tools. One machine was tightening bolts and drilling, one for laser printing and another machine for embossing plate,” the statement said, adding, it was found that the premises was basically meant for warehousing imported goods. The two directors of the company, who were the main persons behind the whole scam of evasion of customs duty, have accepted their involvement in the fraud and they have been arrested, the DRI said. “Detection by DRI of this modus operandi of import of misdeclared E-rickshaws will not only boost the ‘Make in India’ campaign of the government by discouraging such fraudulent imports by unscrupulous traders but will also provide a level playing field to the domestic manufacturer vis-a-vis imported e-rickshaws,” it said.

Between Black Friday and Cyber Monday alone, 79 percent of mobile phone shoppers ditched their carts, leaving a cringeworthy amount of money on the table. While shopping-cart abandonment strikes both large and small companies, it’s a much bigger concern for startups.Related: The Key to Converting Online Sales Leads: SpeedA quarter of online customers abandon their shopping carts because of complicated website navigation, and 21 percent ditch their transactions due to long checkout processes. Large retailers likely have the funds to address these problems. Startups, in contrast, often have limited resources, alongside their lower revenues. As more customers abandon their purchases, the lost sales create an unfortunate snowball effect: The rich get richer, and startups stagnate.But fear not: Applying these five simple, low-cost strategies will increase conversions and lower your number of abandoned carts: 1. Poll before you build.The best strategy for preventing shopping-cart abandonment appears early in the app-planning process. Before you build, research your customers to determine how they’d expect your app to work. Mock up the screens to put them in front of your customers before you build them. Knowing your customers and creating a user-friendly experience based on their expectations will undoubtedly increase sales.Continue communicating with your customers throughout the building process. Have them test your app’s features, and record their feedback. You’ll learn what’s most important to them — whether that means speed, efficiency, simplicity, security or all of the above.2. Simplify the checkout process.Avoid turning users off with complicated checkout systems. Some businesses make the mistake of asking customers for so much information that they decide to buy their goods elsewhere. Your customer should know how much work is left to complete his or her order. A clean interface with a short pathway to purchase will keep customers from getting frustrated.One simple way to cut the length of the checkout form is to allow a customer’s ZIP code to autopopulate his town and state. You can even automatically migrate the sign-up information you collected into the checkout form. That way, the fields are already filled out; the buyer just needs to confirm them.Related: How to Make Your First Ecommerce Sale (Infographic)3. Add security measures.A quick and easy transaction means nothing if it isn’t secure. Identity theft is a growing concern — more than 12 million Americans fall victim to it every year — and consumers are more cautious than ever. In fact, 17 percent of mobile shoppers abandon their shopping carts due to security worries.A good way to combat this is by using verification products and services that verify every transaction through a third party. These security measures ensure that all user information is encrypted and kept safe. Make sure your customers know that you encrypt their information. Customers who are nervous will look for security measures, and they’ll be less likely to ditch their purchases if they believe their concerns have been addressed.4. Send gentle reminders.One of the advantages of an app is that you can send push notifications to your customers. Use this feature to remind them that they have items in their cart, but be wary of antagonizing them. Program the app to send alerts only to users who selected high-value items or spent several minutes browsing before filling their carts.Push notifications can also be useful for providing purchase confirmations and tracking updates and informing customers of special offers.5. Encourage sales with discounts.Offer incentives to customers for making purchases through your app. Although discounts carry an initial cost, they can effectively grow your user base, boost customer satisfaction and jump-start your revenue if utilized correctly. Food delivery startup Caviar did just that by waiving its delivery fees for first-time customers. The company also offers a $20 credit to users who share the app and get friends to make purchases.These are five easy and inexpensive ways to improve your mobile experience and turn those abandoned shopping carts into sales. Listen to your customers from the get-go, and make sure they feel safe — soon, they’ll be clicking the “buy” button. Related: 4 Strategies to Stop Shopping Cart Abandonment on Mobile
A three-year-old, well-connected San Francisco startup has signed a contract to buy and install a whopping 500 megawatt hours worth of grid batteries from Tesla. That size of deal is the equivalent of installing tens of thousands of Tesla’s Powerwall batteries, many in California, over the course of the next five years. The startup is called Advanced Microgrid Solutions and the company installs batteries in buildings and uses smart software to manage the collective battery energy to help utilities better run the power grid.The company is led by co-founders Susan Kennedy and Jackalyne Pfannenstiel, who each have long history in the energy industry. Kennedy is the former chief of staff to California Governors Arnold Schwarzenegger and Gray Davis, and former commissioner for the California Public Utilities Commission. Pfannenstiel previously chaired the California Energy Commission, worked at utility PG&E for twenty years, and was the assistant secretary of the U.S. Navy in charge of energy strategy. In addition to Advanced Microgrid Systems’s well-connected founders, the company also has an important advisor—DBL Investors’ Managing Partner Nancy Pfund, who was also an early investor in Tesla.Kennedy described the partnership with Tesla as “a big deal” in an interview with Fortune and said the company chose Tesla as the battery tech supplier for its projects after reviewing tech from all over the world because “frankly, Tesla was the most powerful and scalable and in a class of its own.” Tesla is currently using lithium ion batteries from Panasonic and has developed its own power electronics and battery management software system. The batteries it sells to utilities and partners like Advanced Microgrid Solutions is called the Powerpack, while the battery systems for homes and businesses is called the Powerwall.During peak usage times, or periods of fluctuating production from renewable energy sources, batteries can reduce the burden on the power grid or provide a continuity of service. In this way, utilities can use batteries to replace tapping into peaker power plants, which are expensive and dirty power plants that are turned on during periods of very high power grid usage. When batteries are utilized in conjunction with renewable energy, the storage systems could offer needed energy on the grid when the sun starts to go down or the wind suddenly stops blowing.For commercial building owners, such as a Walmart for example, battery energy can be turned on when power grid rates are high, lowering a company’s monthly electricity bill in a process called peak shaving. The energy storage industry calls these installations in buildings “behind the meter” energy storage.Advanced Microgrid Solutions isn’t the only player in town building projects using software, power electronics and other vendor’s batteries. Others include startups like Stem, Greensmith Energy and GELI and big companies like GE. Tesla is also working with a variety of battery projects and software developers including large public companies AES and EnerNOC.Still, Advanced Microgrid Solutions stands out from its many competitors in that it combines both these utility and commercial applications in its installations and system management. The company’s software aggregates the collective load from the buildings connected to the system, creating what the startup calls “fleets of hybrid electric buildings.” It’s like how a hybrid car switches from gasoline to electric when needed; the buildings can move on and off of battery energy when needed.The company surprised the energy storage industry last year when it came out of stealth and revealed a big 50 megawatt deal, (across four contracts) with utility Southern California Edison. That’s 50 megawatts of four-hours-worth of capacity, so the project will make up about 200 megawatt hours out of Tesla’s total 500 megawatt hour contract.Tesla’s deal with Advanced Microgrid Solutions includes supplying batteries for the Southern California Edison project in addition to other utility deals in the future. Advanced Microgrid Solutions plans to install its first 10 megawatt project in buildings in Irvine, California in 2016.Southern California Edison is just one of California’s utilities that are attempting to fulfill the state’s mandate which says utilities need to collectively install over a gigawatt of energy storage by 2020. The utility announced 250 megawatts worth of energy storage projects last year and Advanced Microgrid Solutions won a deal for 50 megawatts of that.The California mandate has kickstarted the state energy storage industry, and dozens of companies of all sizes have entered the space not only in California, but nationwide. GTM Research estimates that 220 megawatts worth of energy storage will be installed in the U.S. in 2015. There were already about 5.8 megawatts of energy storage installed in the U.S. in the first quarter of this year, says the research firm.Advanced Microgrid Solutions has been quiet about both its equity financing and project financing that will support the installation of all of these battery projects. But, as I reported last week, the startup is in the process of raising a round of $18.8 million in equity from investors to run its business. The company plans to announce details of its project financing down the road.The energy storage industry will be watching closely to see whether Advanced Microgrid Solutions’ unique combination of connections, experience, smart software, and its new Tesla deal can give them an edge in a rapidly emerging market. 5 min read This story originally appeared on Fortune Magazine This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience.
