<description><![CDATA[Liquid Metal Battery, a company pursuing a breakthrough battery design, has attracted Bill Gates and an oil driller as seed investors.Many battery companies are working to improve existing technology, but the founders of Liquid Metal Battery are taking an unusual approach that they hope will slash energy storage costs and deliver batteries able to store several hours of wind and solar power. The target of the company, which was spun out of the Massachusetts Institute of Technology, is to have demonstration systems connected to the grid in three to five years, executives said. An official announcement of the series A funding is expected next month.Liquid Metal Battery, as its name implies, is building a battery where all the active materials--the cathode, anode, and electrolyte--are in a liquid form at high temperatures. In most of today's common batteries, such as lead acid and lithium ion batteries, the cathode or anode are solid. The all-liquid approach reduces the degradation of electrodes that can happen in batteries and allows for the high flow of current needed for bulk storage on the grid. Most importantly, though, it means the battery can built using relatively cheap components, said materials chemistry professor and co-founder Donald Sadoway. He conceived of the original idea by drawing on his experience around making metals, including giant aluminum ingots, using electrochemistry at an industrial scale.Professor Donald Sadoway shows off a model of an all-liquid metal battery prototype under development.(Credit:Martin LaMonica/CNET)&quot;I looked at how aluminum smelters take a giant hall with liquid aluminum and fill it and I said, 'That's where you can get economy of scale.' If you want a big battery, you build one big battery and you can't do that with today's technology,&quot; Sadoway said in an interview. &quot;The scalability is going to be enabled by borrowing the lessons of 125 years of aluminum smelting.&quot;Liquid Metal Battery has licensed technology developed at Sadoway's lab, where work will continue in parallel. Sadoway intends to take a yearlong sabbatical to be scientific adviser to the company. His lab received a three-year $6.9 million grant from the Department of Energy's ARPA-E research agency two years ago and a four-year, $4 million grant from oil company Total to research how to adapt this battery chemistry for home storage.Sadoway decided to spin out a separate company because researchers were limited in their ability to test out larger prototypes which were initially about the size of a hockey puck. He also wanted to hire people with the engineering experience able to develop and test a commercial product.&quot;We're taking what we consider the top prospect chemistries from the lab study and we will look at how the laws of scale apply because no one has every built one of these before,&quot; he said. &quot;If we do some very elegant science, that alone will not be considered a success.&quot;The company is now working on a prototype system where each battery cell is about the size of a pizza box and able to store about 200 watt-hours and work at 1 volt. Its next task is to build a larger cell about the size of a Ping-Pong table, where many individual cells would be stacked in a battery pack. The target is to make a grid storage device able to deliver a few hours of power to fit into a shipping container, while a home battery would be about the size of a basement freezer, company executives said.Layer cakeIn the past few years, truck-size batteries have been connected to the grid for certain applications, such as maintaining a steady frequency or local back-up power. But batteries, in general, remain very expensive and are mainly used for delivering quick bursts of power. Batteries are starting to be used in conjunction with wind and solar farms, but Liquid Metal Battery is seeking to slash the cost of storage to the range of $100 per kilowatt-hour, several times lower than today's prices.Providing many hours of storage at low cost, what many consider the holy grail in storage, would allow solar and wind farms to &quot;firm up&quot; variable wind and solar power, which sometimes rely on natural gas plants to provide a steady flow of power. Sadoway said different liquid metal chemistries could be used for different applications, such as storing energy at off-peak times and releasing it onto the grid at peak hours. That is now done by pumping water uphill to a reservoir and releasing it through a water turbine at night, which is cheap but limited in where it can be done.This model of a prototype shows the makings of an all-liquid battery cell. The bottom red layer is the heavy liquid metal cathode, the yellow is the molten salt electrolyte, and the green above is the less dense anode. The container is surrounded by an insulator material.(Credit:Martin LaMonica/CNET)Sodium sulfur batteries and some types of flow batteries, which are already used for grid storage, use liquid electrodes today, said Luis Ortiz, the president and co-founder of Liquid Metal Battery. Where this company will be different is having liquid metal electrodes and a liquid electrolyte made of molten salt. The approach has performance and price advantages, he said.&quot;We have all-liquid components so it should last much longer because there won't be a build-up of stresses or cracks,&quot; Ortiz said. &quot;We have reason to believe they could last tens of years.&quot;One of the key technical challenges is to build a battery that is self-heating. For the metals and salt to remain liquid, researches have been working with metals at temperatures between 400 degrees and 700 degrees Celsius. Because the flow of large amounts of current generates heat, the battery itself can heat itself once it has reached the right temperature, but product designers need to sort out best battery shape, Sadoway said. Early prototypes used liquid magnesium and liquid antimony as positive and negative electrodes. Because the metals and the molten salt electrolyte have different densities, they remain separated as three distinct layers, much the way oil and vinegar don't mix.When the battery is being charged, a chemical reaction causes compounds dissolved in the electrolyte to form magnesium and antimony metal. During discharging, the chemical reaction happens in reverse, releasing electrons to create an electrical current onto the grid. In a difference from most batteries, the electrolyte gets thicker and the two liquid metal electrodes get thinner while discharging.The container that holds the liquids itself acts as a conductor. Actual batteries will need to be engineered with an insulator around the container because they operate at high temperatures.Student GatesThe group is now working on a second-generation liquid metal battery that acts in principle the same way that today's lead acid, lithium ion, and nickel metal hydride batteries do, said Ortiz. In that design, metal ions pass between the anode and cathode and the electrolyte remains constant, he explained.The company is cagey on exactly which metals researchers are working with. But in general, they are working with pairs of metals of different densities that are relatively cheap, Ortiz said. Similarly, the electrolyte used can be very cheap material, such as table salt or rock salt used to salt roads.Related links&amp;149' Energy storage on grid heats up (photos)&amp;149' Grid storage gets updraft from auto batteries&amp;149' Can 'energy storage as a service' beef up the gridThe technology behind Liquid Metal Battery came to the attention of Bill Gates through the lecturing of professor Sadoway, whose solid-state chemistry classes can be viewed online. In an appreciation written for MIT's 150th anniversary, Gates singled out Sadoway's work on energy storage.In forming a company, Liquid Metal Battery took funding from Gates' venture arm and a large corporation with the hopes of having long-term investors. &quot;We were interested in taking patient money with deep pockets because these are large systems that take a significant amount of capital,&quot; said co-founder David Bradwell.Gates, who has a deep interest in clean energy and climate change, said last year he has invested in five battery-related ventures because inexpensive storage is a &quot;tough problem (that) may not be solvable in any economic way.&quot;Research on the all-liquid battery approach has been going on for about five or six years and Sadoway said the group has met the technical and cost milestones set out by investors and ARPA-E. &quot;We've got to get (total installed costs) down below $250 a kilowatt-hour. That's the issue--cost,&quot; he said. &quot;Our work is cut out for us (but) I'm guardedly optimistic.&quot;<br/><br/>0 Vote(s) ]]></description>

<description><![CDATA[The only thing that could make this cooler is if it was made out of Legos.(Credit:Jim MacArthur)A Turing machine is a very simple computer that manipulates symbols on a strip of tape to perform feats of logic. There isn't really much of a purpose to them these days' they exist as a novelty based on early computational theory by the great mathematician and computer scientist Alan Turing. They're made as a type of thought experiment to show the advantages and limits of mechanical computing. To really understand what a Turing machine demonstrates, you probably have to be the type who can speak binary. Many have been made over the years, but one caught our eye on YouTube this week (video below). We didn't notice it because it's elegant or attractive--indeed, it's rather harsh-looking--but because it's entirely mechanical. It uses magnets and springs, but no electronics or even electricity. It was made by British hobbyist Jim MacArthur as a demonstration for a Maker Faire in the U.K.Most Turing devices use a type of tape on which symbols are punched, but this one moves along a metal grid. Ball bearings are dropped into grid squares based on the data input via a series of small levers. The positions of the balls on the grid act as symbols. When one knows what they're doing, the pattern of ball bearings on the grid can be translated into a rough program.For a logic unit, it uses a left-or-right switch mechanism to create binary input. It has up to 5 input symbols that allow for 10 &quot;states.&quot; If that doesn't make sense to you, that's OK, it's not really supposed to. It's a technical way of saying that while this DIY machine won't catch up to a pocket calculator anytime soon, it's still an impressive feat of engineering for not having any batteries.The entire thing is made from scrap metal collected by MacArthur. What's more, it's mechanical to the point that it's powered by turning a wheel by hand. At the end of the video, MacArthur points out that his current version uses a small electrical motor as an option, though it works just fine when powered by steam, too.Again, the machine doesn't actually do much if you're not really into computer science, but MacArthur is considering a new model that actually does do something useful. If you tried to do something productive with this machine, you'd be in for a bit of a wait. MacArthur says on his blog that while the gizmo looks cool, it would take months to add 2 to 3. Yes, you can actually calculate how long the problem would take to solve in a fraction of the time it would take to solve it.DIY doesn't have to be useful, it just has to be cool.To share your DIY project, simply e-mail a description of 350 words or less, including all the geeky ins and outs of your invention, plus relevant links and photos, to crave at cnet dot com.

<description><![CDATA[A new free tool from the makers of Norton attempts to quantify the real-time state of cybersecurity. It makes its debut today alongside the latest version of Symantec's all-in-one consumer security suite, Norton 360. The Norton CyberCrime Index lies somewhere between a weather report and the United States' threat level advisory system, and Norton 360 version 5 launches with a direct link to it.Norton CyberCrime Index (images) The CyberCrime Index uses a statistical model based on information from Symantec's Global Intelligence Network, ID Analytics, and DataLossDB. At the top level, the CyberCrime Index takes this data and creates a number evaluating the relative risk of the threats of the day. However, it also provides a more in-depth look at active threats, threat trends, and provides advice on what kinds of behaviors are being most heavily targeted that day.Symantec has had the statistical model and algorithm it uses in the CyberCrime Index vouched for by the University of Texas at San Antonio. The service is set to go live this morning, so check back here later today for a hands-on update.Symantec isn't forcing the index on any of its users, though the new version of Norton 360 does include a direct link to the service. Version 5 of Norton 360 includes the real-time threat map that debuted in Norton's 2011 consumer suites, along with all the features that were introduced in Norton's 2011 consumer suites last fall. These include updates to Norton's Insight engine, which instantly checks a file's origins and how long it's existed to determine how safe it is. The new version of System Insight also profiles your programs to determine if any of them are slowing down system performance, and automatically alerts users when a program is eating up too many resources.Now included in Norton 360 is the Norton Bootable Recovery Tool, which will clean heavily infected systems enough to get Norton 360 installed, and can create a rescue tool on disc or USB so that your computer can be resuscitated. The backup features in Norton 360 have been improved, too, adding in automatic file encryption to the backup process. Lastly, Norton Safe Web's social-media scanner has been imported from Norton Internet Security 2011. Currently, it still only supports Facebook, though that's a good start: it will check your Facebook wall and news feeds from within Norton.Norton 360 version 5 (review) comes with a 30-day trial and can be used on up to three computers. A one-year license with 2GB of online storage retails for $79.99. Bumping that up to 25GB of storage costs $99.99.<br/><br/>0 Vote(s) ]]></description>

<description><![CDATA[Apple is reportedly switching up the wireless chipset used in future versions of both the iPad and iPhone.(Credit:iFixit)Is Apple moving to a new wireless chipset supplier for the nextiPad andiPhone An unnamed but &quot;reliable&quot; source is quoted by Engadget today saying that Apple is going to ditch the current Infineon chipsets used in both devices and move to Qualcomm instead. The report seems entirely plausible.Verizon already let it slip that it's going to have an iPad that runs on its network. It's very likely that will be for its CDMA network, and not LTE. The current iPad model only works on GSM networks. Apple probably doesn't want to have to make two different iPads the way it's currently making two different models of iPhone (one with GSM chips for AT&amp;T et al., and one with CDMA for Verizon and perhaps other future carrier partners), so switching to a chipset that allows the device to connect to both networks would be smart. Qualcomm has that, or is going to, very soon. It's long been rumored Apple would eventually start shipping a dual-mode iPhone--a report that the iPhone 5 would work on GSM and CDMA networks hit back in October--so going that way with both of its flagship mobile products makes a lot of sense.Engadget also notes that while the next iPad won't have a USB port, it will have an SD card slot, and has some images of what it would look like.<br/><br/>0 Vote(s) ]]></description>

The carrier announced today that Dell will be bringing its Streak 7 tablet to its 4G network in the next few weeks.The 7-inch Streak 7 will be Dell&amp;'s first 4G tablet, as well as the first to be available to consumers in the US.Unlike LG&amp;'s G-Slate, or Motorola&amp;'s Xoom for Verizon, the Streak 7 won&amp;'t be packing Android 3.0, the delicious new Android update for tablets. Instead, it will be packing Android 2.2 &amp;8212' which makes sense, otherwise we wouldn&amp;'t be seeing it so soon. It weighs less than a pound, features a dual-core Nvidia 1 gigahertz CPU, and also has front and rear-facing cameras at 1.3 and 5 megapixels respectively.Next Story: AT&amp;038'T&amp;'s answer to the Verizon iPhone: A $49 iPhone 3GS Previous Story: Mac App Store dominated by gamesPrintEmailTwitterFacebookGoogle BuzzLinkedIn      DiggStumbleUponRedditDeliciousGoogleMore&amp;8230'          Tags: Android, CES, CES 2011, Streak 7, tabletsCompanies: Dell, T Mobile          Tags: Android, CES, CES 2011, Streak 7, tabletsCompanies: Dell, T MobileDevindra Hardawar is VentureBeat's lead mobile writer and East Coast correspondent.
