Olar Power at the Time of First Half of the Solar Energy Production in China?
Olar Power at the Time of First Half of the Solar Energy Production in China?
Switching to solar power is one way to limit the impact your household has on the environment. By using photovoltaic cells, you can take advantage of the free energy provided by the sun every day without producing carbon emissions or running up your electricity bill. Solar power is not for everyone, however, and generating electricity with solar panels offers some distinct disadvantages to conventional generation, as well. Knowing the pros and cons of solar power can help you make the right choice for your home. Solar has a clear advantage over traditional electricity generation in its effect on the environment. Most power in the United States comes from burning coal, which produces a large amount of carbon dioxide in the process. The Environmental Protection Agency estimates from Energy Information Administration data that, as of 2001, the average household used 900 kilowatt-hours of electricity per month, generating 14,976 pounds of carbon dioxide per year (see References 1 and 4). Electricity generated via solar panels, on the other hand, produces no carbon dioxide emissions at all. Over the lifetime of your solar installation, solar panels can make a large difference in your family's carbon footprint. Another area where solar power offers advantages is in the cost of generating electricity. Burning fuel for power costs money, and fossil fuel markets can be heavily dependent on world events and local supply issues. According to the EIA, the average cost of consumer electricity in December 2010 was 11.04 cents per kilowatt-hour (see References 3). A solar panel, however, produces electricity with no fuel or ongoing costs, and will do so for the life of the installation. Even if you only use a small panel installation to supplement your home's power needs, you will be able to see the benefit on your monthly power bills. While generating power with solar cells is essentially free, purchasing and installing those panels is not. Installing solar power for your home can be an expensive proposition, especially if you are attempting to derive all your power from solar electricity. Solar installations can cost tens of thousands of dollars, and while you may be able to apply for grants or loans through your federal or state government, the initial costs of switching to solar will likely remain high, and repairing damaged panels may also be an expensive prospect (see References 6). An inherent disadvantage of solar electricity is that it only works when the sun is up. Photovoltaic cells stop producing current when not in direct sunlight, which means you will need to have a backup power source or use storage batteries to provide power at night or during inclement weather. Furthermore, the amount of power you can generate using solar panels depends greatly on your local climate. The National Renewable Energy Laboratory estimates that a solar panel installed in the Sun Belt may produce as much as twice the electricity per day as one installed in New England (see References 2 and 5).1. Why can't we use solar power for cold storage of 5,000 tons?I can't see why we can't, but I can see reasons we might not.The technology exists for small scale refrigerators and freezers, using a small solar concentrator and similar equipment to that found in gas-fired refrigerators and freezers. The ones I know of have been built by their owners by modifying commercially available dual-energy units to use the solar concentrator rather than a gas supply, and rely on the electrical cooling system when the sun doesn't provide enough cooling. Some have been successful, but they're not cost-effective compared to just using a commercially available solar electricity supply all the time.Most of the people who claim to have built them are no longer using them or are evasive when asked, in my experience.To use this technology for 5000 tons would require a large installation similar to a solar power tower. There seems no reason this could not work in theory. But the cost would be prohibitive, and there are environmental concerns over such plants.Why can not we use solar power for cold storage of 5,000 tons?.2. How exactly does solar power work???Photovoltaic cells are solid state devices, meaning they are more akin to microchips than to traditional power plants, and they have no moving parts. In a nutshell: the energy provided by the sun's photons (light) excites electrons in the cell, which produce an electric current. Solar power is considered a direct method for producing electricity, in that electricty is produced directy by the sun. This is in contrast to traditional methods, which heat steam that is then used to turn a turbine, which powers a generator3. Does Japan have 50 square miles of land for solar power?They can just build new nuclear power plants, or replace them with coal plants. Solar is a silly idea unless they just want to energize dinky little light bulbs
Why It Takes Decades to Produce a New Solar Material
Why It Takes Decades to Produce a New Solar Material
The solar industry is abuzz over a relative newcomer that burst onto the scene less than a decade ago and has risen rapidly through the ranks. The all-star rookie has also been published in high-impact academic journals in the last few years, but it is not a newly minted professor or a hot solar startup. It's a material known as perovskite.Materials scientists started testing perovskite's sun-capturing qualities in the 2000s, and by 2009, a team lead by Tsutomu Miyasaka from Toin University of Yokohama in Japan had produced a solar cell that converted 3.8% of the sun's light into electricity, a respectable amount for such a new material. Just last fall, another group lead by Henry Snaith from the University of Oxford published a breakthrough-their perovskite solar cells were 15.4% efficient.In a world where gains of fractions of a percent are lauded, such a leap was unprecedented. "Very few come in out of the cold and have a 15% conversion efficiency." says David Ginley, a research fellow at the National Renewably Energy Laboratory."It's exciting," says Michael McGehee, a professor of materials science at Stanford University. "It's a new material with a lot of potential."That excitement is evident in recent news coverage. Even Nature , a well-respected academic journal, hailed Snaith as one of the 2013's "ten people who mattered." "This year, Snaith amazed materials researchers by massively boosting the efficiency of solar cells made with perovskite semiconductors," they wrote.Those plaudits come with a small catch-they tacitly presume that perovskite will continue its rapid ascent. If it does, the material truly could be revolutionary. Currently, photovoltaics cost between $2 and $5 per watt depending on the scale of the installation. That's significantly lower than just five years ago, though it's still not competitive with coal or natural gas. But if perovskite continues to gain efficiency, it could tilt the playing field solidly in favor of solar power.The target is 25% efficiency. Very few types of cells exceed that goal, and even fewer are commercially available currently. "A lot of people think that you need the efficiency of the cells to be up near 25% because if the efficiency is lower, you need a larger area to get the power, and the larger area, the more the installation costs are," McGehee says. Perovskite made waves with how quickly it broke 15% efficiency, and unspoken assumption in many articles is that the material could breach 25% in a matter of years, not decades.Snaith, whose team achieved the recent perovskite milestone, seems convinced that perovskite already has commercial potential. He has founded a company that's striving to produce perovskite solar cells in mass quantity, which he says will happen in "three to five years."Snaith's compressed timeline mirrors the great strides perovskite has taken as a photovoltaic material. But the road from the laboratory to the rooftop can be filled with unexpected speed bumps, something known all too well by researchers and manufacturers of copper indium gallium selenide, or CIGS, a photovoltaic material that's just recently become available on the market. In fact, the story of CIGS could be viewed as a cautionary tale, one that might temper some of the excitement surrounding perovskite.CIGS began life as CIS, or copper indium selenide. It, too, is a semiconductor and was originally discovered in 1953 by Harry Hahn and his team at the University of Heidelberg. They published their discovery in Zeitschrift für anorganische und allgemeine Chemie , a German-language chemistry journal. It was not uncommon at the time for chemists to publish in German, though that may have been partly why it was overlooked as a photovoltaic until 1974 when Sigurd Wagner, a young Austrian scientist and a fresh face at Bell Labs, and his team published an article on how his lab-grown crystals that could capture the sun's rays.CIS crystals were expensive and proved difficult to grow, though, which was part of the reason why Larry Kazmerski, then a professor at the University of Maine, started searching for a better technique. It did not take him long. Shortly after Wagner's first paper came out, Kazmerski told colleagues how he deposited CIS in a thin-film on a piece of glass. His first cells were between 4-5% efficient.It was a promising development, but work on CIS was only one part of a larger government investment in solar power. In the 1970s, the National Science Foundation was directing large investments in solar power research for the U.S. government. Much of the money was going toward developing silicon-based solar cells. "Silicon, they knew, would do well eventually. That was the known semiconductor," says Kannan Ramanathan, head of the CIGS team at the NREL. "Yet they wanted to divest, take risks, and nurture thin films."Work on CIS trundled along until 1981, when Boeing scientists Reid Mickelsen and Wen Chen announced at a conference in Orlando, Florida, that they had doubled Kazmerski's efficiency by depositing the material in a new way. Thin-films had arrived.Though silicon remained the favored material, a handful of companies grew interested in thin-film cells and CIS in particular. They wagered that if they could get the chemistry right, thin-film cells would be vastly cheaper to produce than silicon cells, which had to be grown as crystals. Plus, CIS could be deposited on inexpensive glass, reducing weight and materials costs. For Boeing, which used solar cells on spacecraft, lightweight panels would translate into cheaper launch costs.Meanwhile, the aerospace company's continued investment was yielding dividends. Chen and another colleague, John Stewart, figured out in the late-1980s that they could substitute gallium for some of the indium, further raising the efficiency. (That was what put the G in CIGS.)Earlier that decade, oil company Arco had also begun exploring CIS and other thin-film technologies. During the energy crisis in 1979, the company had become a serious player in the nascent solar power industry. After throwing its weight behind CIS research, it quickly developed an alternative to Boeing's production technique. It was not quite as efficient, but was considered easier to manufacture. By 1988, the Southern California-based Arco Solar produced a four-square-foot module with 11% efficiency. That same year, they offered to permanently light the Hollywood sign using solar power.Despite the bravado, things were not going well for the Arco Solar pioneer. Development problems plagued the run-up to production, frustrating its parent company. Plus, the solar power market was not growing as quickly as they had hoped. Looking to cut costs, Arco sold its solar division to Siemens in 1989.Boeing had also lost interest, and left their work to NREL. Researchers in academia and industry had to go back to the drawing board in an attempt to resolve the issues that plagued previous manufacturing efforts. But without the major players, the material that had shown so much promise in the 1970s and 1980s stumbled. It would be almost 10 years before the CIGS industry would recover.Out from the ShadowsBy the late 1990s, Siemens was feeling confident in its progress on CIGS and spooled up a pilot production line. The results of an early run were tested at NREL and scored higher than 10% efficiency. They were the first thin-film photovoltaics made outside of a lab to reach that landmark. But just as Arco had dropped its solar division after it made the 11% module, Siemens started looking for a buyer for the California-based division shortly thereafter. It eventually ended up with another oil company, Shell. (The division ended up being a hot potato; Shell would only own it for four years before selling it to Germany-based Solar World in 2006.)The 2000s could have been another lost decade for CIGS, but then, in 2003, Germany began offering generous subsidies on solar power. That encouraged a number of universities and small companies to jump in the game, who, along with NREL, would end up carrying the torch when, a few years later, Shell "walked away" from their solar division, Ramanathan says.The handful of smaller companies kept at it, encouraged by government subsidies and an influx of venture capital, fine-tuning their materials and lowering their production costs. Then, as so many times before, they ran into a series of unexpected problems. While many companies had become adept at producing cells in the lab, they could not replicate that success on a large scale. Some of these delays were blamed on an incomplete scientific understanding of the CIGS material. William N. Shafarman, a professor at the University of Delaware, and Lars Stolt, a professor at Uppsala University, wrote in 2003 that the "lack of a science base has been perhaps the biggest hindrance to the maturation of Cu(InGa)Se 2 solar cell technology as most of the progress has been empirical." At many companies, the cart had gotten in front of the horse. Between 2005-2007, 70% of thin-film panels failed, more than double the failures for 1997-2005. They had to go back to the drawing board, again.Meanwhile, manufacturers also had to perfect how the cells would be packaged and connected. Each wire, sheet of glass, and piece of aluminum had to be tested for durability and reliability. They had to simulate everything from snafus that might take place during installation to 20 years of heat and moisture. Thanks to accelerated testing, the process does not take 20 years, but it can still take many months to several years.Bert Haskell, the CTO at Pecan Street, oversaw these tests in an earlier job as director of product development at Heliovolt, an Austin, Texas-based CIGS company. There, he and his team would subject completed panels to a grueling regimen of abuse. They would yank on connecting cables, drop one-and-a-half-pound ball bearings onto the glass, and fire chunks of ice at the panels at 50 mph. They would subject them to high humidity and drastic fluctuations in temperature. They would bake them and they would freeze them. "Those tests, you might run those for 90 days or six months before you get results back," Haskell says. It was quicker than waiting 20 years, but it was not instantaneous.Add it all up, and you quickly realize that just testing the non-photovoltaic part of the module took several years. Some tests could occur in parallel with work on the CIGS cells themselves, but in the end, the entire package still had to be tested and certified.It was not until the mid-2000s that CIGS-based solar panels began to trickle into the market, more than 30 years after the material's initial discovery as a photovoltaic. Today, CIGS cells remain costly relative to silicon cells and have captured just a few percent of the market. The future could still be bright, but it will require many more years of sustained funding, research and development.Judging by the challenges CIGS confronted, it's likely that perovskite solar cells have a long road in front of them. Though the material has shown great promise, moving out of the lab and into production is not the same as producing high-efficiency cells in the lab. It takes time. "The development time for most technologies is 20 to 30 years," says Ginley, the NREL scientist."Haksell agrees. "When a scientist discovers a new material in the lab that has some kind of unique property, going from that to the point where it's applied in a useful product, it just takes a long time." (I followed up with Snaith regarding his three-to-five-year commercial timeline for perovskite solar cells, but have not heard back.)Perovskite's biggest stumbling block could be water. While most solar cells do not react well to water, perovskite's current formulation is an ionic salt, which means it's highly susceptible to water damage, both McGehee and Ginley tell me. Solar manufacturers work hard to keep their products sealed, but water has a tendency to work its way into the smallest of gaps, including those cracks that happen during installation or any of the many heating and cooling cycles solar panels endure. Reformulating the material while keeping the basic chemical structure could reduce the potential for water damage, but that would require years more research."There's still a lot of questions that need to be answered," McGehee says of perovskite. "It is exciting and I do not want to take away from it in any way, but we still need to have a wait and see attitude before we will know if this is going to be a commercial success."Solar system with both grid tie-in and backup power without battery?A Great Big Switch is simplicity itself. You need any Siemens subpanel of 12 spaces or more, and the ECSBPK01 interlock ($25) and two 2-pole breakers. A 60A from your main panel and a whatever-A from your off-grid source.You leave 2 rows empty for style points, then below that you fit the breakers for the circuits you wish to be capable of functioning on alternate power. You can have 36 of those (32 if you want to keep those style points) and if that is not enough, feed a sub-sub-panel.Throw the 2 top breakers to the right, you are on utility. Throw the 2 top breakers to the left, you are on ???. Part 1: The above. Part 2: ??? Part 3: ProfitCan we do this thing totally batteryless? I seriously doubt it. Here's why. Your freezer starts up, and for a few milliseconds it's going to pull LRA of about, say, 3000 watts. And it expects this in AC power, and so you have an inverter behind an MPPT controller. The inverter goes "OK, that's 25A, hey solar system, I need 125A" and the solar system goes "Unable". Voltage plunges toward zero, which means inverter output voltage plunges toward zero, and the freezer sits there at LRA unable to start. And this continues indefinitely until ??? some safety system in the inverter kicks in and shuts off the inverter. Why did not this work? You have 5000W of solar panel. Yes, if it's aimed directly square on to the sun. At the angle it's at, at the angle of the sun, 3000 is the best you could do, but it's also cloudy. In fact your panel has been passing in and out of clouds all day, bouncing practical output between 500 and 3000. So you need at least an ultra-capacitor to get loads started, and really it should be enough of a battery so the freezer can run a normal cycle without emptying the ultracaps in 5 seconds because a cloud rolled over. These are not good failure modes for either the inverter or the freezer. Obviously what you are afraid of is a $5000 battery bill, and then, the recurring $5000 battery bill if PV batteries are anything like car batteries. Some are, some are not . But the size of the battery is variable. It's all about sizing, really. You need the battery to carry you through the stuff you do not expect - like clouds. So it can be quite a small battery pack, as small as $100 on the low side. If you do not want to gird up for full fridge lights Roku router TV for 3 days straight with little usable sun, you do not have to. If you ever change your mind you can always add battery capacity. You may imagine solar is a steady-state source, but that's not really true. See if you can get a second-by-second readout of someone's solar system. They are all over the map on days with any clouds at all. Again, batteries make that moot for in-and-out-of-clouds days. But do not overestimate their generating ability during deep clouds. Storm clouds can be quite dark - yesterday I was working by daylight and suddenly it simply became too dark to work - a big storm rolled through. And of course snow obscures the panel totally. (except Solyndra which had a very slick answer to that, but nobody cared.) You could wake up and find the panel covered in ice from an ice storm that also knocked out your power. (It's too cold; the ice does not chisel off without risk of panel damage). So I think you are laying an assumption that solar power will always be ample during a power outage. I am not sure of that at all, but I am from the rust belt - power outages usually happened in winter storms, where you would not have the solarization to make a panel very productive, first because of clouds/snow/ice, and second because it's winter in the first place. You can also top up battery capacity with a generator if you have long sunless runs.
City Buildings and Vehicles Could Run on Sunlight, Say Councillors
City Buildings and Vehicles Could Run on Sunlight, Say Councillors
Regina city councillors spent part of Monday evening dreaming up a city where police cars, buses and hockey arenas draw their power from the sun.The debate came in response to a motion from Coun. Mike O'Donnell, who called on city hall to study whether city-owned buildings could be fitted with solar panels.He said the price of the technology has consistently fallen in recent years. He proposed using them to take facilities off the power grid, saving the city money."Maybe, just maybe, we could actually create revenue," he added during Monday's city council meeting. His motion directs administration to study whether there could be a financial benefit to selling the power.The motion passed, giving administration until December 2019 to prepare a report.Councillors also floated the idea of using the panels to power electrified city vehicles - possibly including buses and police cars.Mayor Michael Fougere speculated that city hall itself could be a good site for the panels. He said he sees a "strong business case" for O'Donnell's idea. Based on preliminary information, he said the city could see a return on investment within 10 years.But the mayor also cautioned that the city won't be able to sell its energy to residents."It's not allowed by SaskPower," he told reporters after the meeting. "They have a monopoly on that. So when we talk in terms of generating revenue we have to be careful."City staff said that talks with the Crown corporation are ongoing, including on using solar power to run park lighting. A SaskPower spokesman confirmed that to the Leader-Post, and explained there are programs which allow the sale of excess electricity back to the grid - though not directly to customers.But Coun. Andrew Stevens wasn't convinced the city will find a helpful partner. He told council that he's discussed the matter with other municipalities, and heard many officials call SaskPower "the biggest obstacle to advancing solar energy."Jackle responded that the Crown is aiming to expand the role of solar power in the coming years, as part of a broader plan to produce 50 per cent of its power through renewable sources by 2030. Solar will still make up less than five per cent of the total, however, according to details of the plan.Stevens said the commitment leaves him "hopeful," but still skeptical about follow through."That commitment needs to be backed with money and policy, as well as support from government," he said. "Right now, it really is focussed on coal."SaskPower is planning to complete a "broad review" of self-generation programs by the end of this year, according to JackleO'Donnell said that he hopes the changes will create new revenue streams for Regina."SaskPower has a mandate to also look at alternative sources," he said. "Well here we are. We have lots of assets, lots of buildings, lots of rooftops and lots of land. We can help them solve that."In the meantime, he said the city could start by installing panels on fire halls or newer buildings like the International Trade Centre. He thinks they could generate surplus power that could then be funnelled to other city facilities with higher energy needs, like hockey arenas.O'Donnell's proposal comes shortly after . He said he wants Regina to be a "forward-looking place.""I think there's times where we get mired down in terms of the day-to-day - the potholes and so on," he said. "I understand that's on people's minds, but I think we have to look forward to technologies to solve some of the problems that we have."

Graffiti Be Gone: How to Remove a Vandals Art From Your Garage Door | Hicklin Door Services
After watching hours of renovation shows on television, you've taken the term "houseproud" to a whole new level. You've ripped out the kitchen and updated the master bathroom. You even hired professional landscapers. The curb appeal is off the charts. But then a vandal hits your garage door with a can of spray paint! What to do? The Property Brothers have not covered this topic yet. Graffiti may have started as an urban blight, but it has spread to the suburbs and beyond. Nobody's home is safe.When faced with this unfortunate situation, you could hire a company that specializes in this type of cleaning. But ask yourself, "What would Mike Holmes do?" He would take it as a challenge to remove the graffiti himself-or at least try. There are several cleaning products to tackle the problem. Here, we channel the spirit of HGTV and provide helpful hints for erasing the damage.What are you waiting for? Get outside and start this job as soon as possible, before the paint dries and takes hold. Try to remove graffiti within the first 24 to 48 hours. You wo not regret getting a head start the same day.It's all about the (spray) paintA solvent is a chemical substance that dissolves something else-in this case, spray paint. There are three types of solvents:• Hydrocarbon solvents such as paraffin, with lower solvency power but they effectively separate from water.• Halogenated solvents, which typically belong to the family of chlorinated chemicals.Okay, that's the chemistry. Here what you need to know. Strong solvents will take off the paint under the graffiti, as well as the tag, if you are not careful. You can not expect a solvent to distinguish between the graffiti and your undercoat of exterior paint on the garage door. Knowing that, proceed with caution, do not over‑saturate the stain with solvent, scrub lightly and be sure to work in small areas. (Note that wooden doors are particularly vulnerable to solvents).Try mineral spirits, also called white spirits. They are a type of petroleum distillate used to thin paint. Note that they are cheap and easy to use, but does not always remove more stubborn graffiti. White spirits will only work on easy‑to‑remove, fresh paint that can be removed with a pressure washer anyway.Naphtha, also a petroleum solvent, is stronger than white spirits. Naphtha will dissolve dry, hardened paint and crayons.If your vandal used markers, isopropyl alcohol is a good option. It also breaks down shoe polish and ink.Lacquer thinner, or acetone, is one of the most effective solvents against graffiti. Acetone softens and dissolves most types of paint-even spray paint. However, acetone can soften certain types of plastic or vinyl, so it's unsuitable on a plastic garage door.If you shy away from solvents, there's an option. "Green" activists and grandmothers swear by a mixture of white vinegar and lemon juice, or white vinegar and baking soda, is an effective cleaning agent. Admittedly, there is less of a risk that you will damage your door's original paint. It's worth a try.Your door's original surface is a big consideration. If your garage door was manufactured with a baked‑on paint, typically polyester based, it's more resistant. If your garage door was repainted in a paint shop by a professional painting company, find out what type of paint they used to do it and how it was applied.Sometimes, it's best to repaintIs your garage door getting old? Think long and hard about spending time and money trying to scrub graffiti off a weathered door. Would not a cosmetic makeover contribute greatly to the overall appearance of your home? If so, just repaint your garage door and do not bother hunting around town for a specialized product to remove graffiti.For help picking the paint color for the makeover, major paint manufacturers have an online visualize tool for exterior paint on their websites, so you can experiment with color combinations and find the perfect look to complement your front door. Designers know that oversized garage doors look best in lighter shades, while smaller doors can be painted a deeper shade. Bold accent colors-red, cranberry, navy-look best on front doors.Before you pick up the paint brush, start by thoroughly cleaning the door's surface and bottom edge. Wash off all surface dirt, grease and spider webs before applying a coat of good-quality primer. If your door is from Garaga or is a door with a similar surface, then refer to our website for the instructions you will need to repaint it.Perhaps your home insurance policy covers damage by vandals! Contact your insurance company to confirm and ask about the deductible. If the deductible is high, it may not be worth submitting a claim.Is it time for an upgrade?Ask yourself an honest question. Was your garage door ready to be replaced anyway? This could be the prodding you were waiting for to make a change. If you live near Des Moines contact us now or call 515-276-3700. We provide no‑obligation quotations by email.Another option is to come and meet us at our showroom. Use our Design Centre to pick out the style of door and look at our image gallery for instant inspiration.What are some ways to increase space for cats in a small house?Use vertical space. Keep breakables out of spaces the cat has access to, behind door or behind glass or at great heights (some cats can jump to the top of a fridge, so that's a minimum). You can train cats that there are surfaces they are not allowed on but (a) you want to do that without the breakables present, (b) there is no guarantee they will behave when not observed, and (c) if the surface is at all interestingly placed, they are almost guaranteed to try again at some point in the future, to check whether the role is still in force. Give the cat other things to climb -- a cat tree (good homebrew designs can be found on the web), shelves that they are allowed on, the top of a cabinet with a reasonable route to it either by climbing or jumping or both. .. Things to crawl under/through are another kind if space.Give them toys to play with in the available space. Remember, to a cat, a room is much bigger than for us. (Reverse-engineering the 8' cat tree I inherited, I figure it's one sheet of plywood, one 8' 2x4 (or a bit more?), one 8' 4x4, four heavy angle brackets, two carpet runners, and screws and glue to assemble it. Not very expensive for something that lets the cats meet me at eye level and/or climb almost to the ceiling.)
Analysis on the Development of Folding Mobile Phone in the Future
Analysis on the Development of Folding Mobile Phone in the Future
Speaking of folding devices, it is no stranger to the post-80s and post-90s. When the tide of smart phones has not swept the mobile phone circle, flip design is one of the major forms of mobile phones. On flip phones, we have actually seen the prototype of folding phones, and ZTE axon m seems to make us feel the "blood relationship" between them.Tiled ZTE axon MFor users like me who are full of feelings for old devices, when I first met ZTE axon m, I couldn't help feeling: the large flip design is really cow X! The folding design can not only obtain a greater field of vision, but also inherit the portability of the flip phone. Even if the screen proportion of full screen mobile phones is large, it is difficult to compare with the two in one screen of folding mobile phones. At the same time, the portability after folding is unmatched by large-size full screen mobile phones.ZTE axon m four modesOf course, even if the most excellent design does not have the support of rich functionality, it is difficult to escape the scope of gimmicks. ZTE axon m provides four display modes for folding form:Dual screen modeDual screen mode: independent display on two screens and independent operation. Similar to the split screen function we use now.Extended mode: two screens are combined into one screen display, so as to obtain a larger field of vision.Chess match in mirror modeMirror mode: two screens display the same content, which is suitable for multi person operation.Single screen mode: the phone folds up and only the home screen works. Convenient one hand operation, more portable.From these modes, the folding design of ZTE axon m covers almost all the usages of dual screen. But obviously, double screen folding will not stop here.Samsung folding screen mobile phoneSamsung folding mobile phoneIt has long been rumored that Samsung will launch a folding mobile phone. The biggest difference between this phone and ZTE axon m is that the folded screen is integrated. Moreover, according to the information currently exposed, a screen is added on the inner side of the folding screen and outside the folding screen for routine operation. In other words, we will see a more technical folding mobile phone.Lenovo folioIn fact, as early as 2016, Lenovo demonstrated folio, a foldable mobile phone with a foldable screen, at the techworld conference. The device can have a 7.8-inch 1920 * 1440 resolution screen in tablet mode, and the screen size is 5.5 inches in folded state. But so far, it has not been listed. The reason may be that the collapsible screen needs to be supplied by a third party, and the supplier is estimated to be Samsung.Lenovo folio with plastic OLEDAt present, there are still many technical challenges in screen folding. Although OLED screens can achieve flexible bending, the demand for cover glass needs to be replaced by flexible materials. The folio mentioned just now is the plastic OLED. While replacing glass, it also brings problems: will the flexible protective layer and display fall off due to multiple folds? What is the scratch resistance of the flexible protective layer, and can it fully protect the display layer? Whether the mass production of flexible protective layer has qualified yield and low price?Samsung folding mobile phoneBut it is certain that once this screen foldable mobile phone is mass produced, mobile electronic devices will obviously enter a new era. When the folding screen technology is mature, the large and clumsy electronic display devices are likely to be replaced, and our living space will be further released.Samsung folding mobile phone after unfolding and foldingOf course, it's a little far away, but the folding phone with foldable screen can really bring a more complete visual experience. This means that the tablet has completed its historical mission.The more use of this folding mobile phone depends on the folding angle of the screen.Folding screen functionWhen it comes to the functions of folding mobile phones, ZTE axon m has actually given us a set of excellent schemes - through the mutual cooperation of two screens, we can realize the functions that are difficult to achieve on one screen. Of course, for future folding screen phones, these functions are not all.1. Handheld simulationNintendo new 3DSA friend told me that the folding design of ZTE axon m is somewhat like a 3DS handheld, and it would be good if the mobile phone could replace the handheld in the future. Theoretically, the folding design of ZTE axon M can indeed be simulated into a handheld mode. One screen is used for screen display and the other screen is used for auxiliary display and operation. Without peripheral accessories, this may be the best solution without affecting the game screen.2. Portable double game consoleThe folding phone can provide two viewsJust now I talked about the folding angle of the foldable mobile phone. If the rotation angle of about 270 degrees can be realized, the mobile phone with foldable screen will provide mirrored game images for two players at the same time as ZTE axon M. In the future, after the folding mobile phone has stronger performance and power, it can realize the split screen experience of two person games with the handle peripherals.3. Mild office tendencySimulated notebook for light office4. Simulation readingOf course, the game is only one of the extensions. Applications with interactive operation interface and display interface can be separated through dual screens to provide display interface and operation interface respectively. When the folded screen is large enough, it can even simulate a laptop. In other words, folding mobile phones will be able to meet a certain degree of office needs.Simulated books bring better reading experienceIn addition, because the folding mobile phone is more similar to real books, it can simulate a more real reading effect. Moreover, smart phones also allow e-books to develop in a diversified direction, such as inserting animations and videos into books to make reading more intuitive. At the same time, it also provides ideas for the paper newspaper simulation of web page layout.In fact, folding is not the only solutionAfter talking about the benefits of folding the screen, are you excited? Here, I would also like to say wait. Don't worry, because the folding mobile phone hasn't really been on the market, and the actual experience has to wait until the real phone is in hand. In addition, there is still a prominent contradiction between the extended function and portability of folding mobile phones. For the best experience, folding phones need to evolve further. Interestingly, the future mobile phone form is not just folding.Cylindrical scroll mobile phoneNot long ago, Samsung applied for a patent. In addition to the foldable design, there is also a scroll design. This design also includes two schemes, one is the cylindrical scroll design, and the other is the rounded quadrangular design. The screen can be retracted on the axis and expanded when necessary. More interestingly, the rounded quadrangular design also includes fingerprint identification function. It's really a brain hole.Rounded quadrangular scroll mobile phoneIn my opinion, this scroll design is less likely to be applied to mobile phones. After all, expanding the screen is a matter that affects the operation efficiency. But it's great to be bigger as office and entertainment equipment. If the performance is sufficient, it's possible to replace the notebook.Flexible mobile phoneFlexible mobile phone is also a good concept, because this design can greatly solve the portability problem of smart phone. For example, users can tie the mobile phone to their arms. Of course, the problem is that the internal components are difficult to achieve flexible bending. Here we also want to talk about Lenovo.Flexible mobile phone and folding mobile phone displayAt the same techworld conference in 2016, in addition to the foldable mobile phone, there is also a practical flexible mobile phone. Lenovo places multiple foldable hinges on the mobile phone through a certain material and new design, and places the components that cannot be folded on the parts that do not need to be folded, so as to realize the flexible bending of the mobile phone. This phone is also not available, but it proves the existence of flexible mobile phone design.Folding or flexible phones seem a little far away now. Can they really come? I can give you a positive answer.When our parents were using the big BB, they didn't expect that there would be mobile phones that could listen to songs and read novels on the Internet in the future; When our brothers and sisters are using Motorola and Nokia, they will not think that one day these mobile phone giants will not go back to the past, nor will they think of today's smart phones and full screen; In the same way, although folding mobile phones now seem far away, maybe our children will use them. Always believe in technology. It never stops moving forward.
Samsung Software Upgrade? (part 2)?
Samsung Software Upgrade? (part 2)?
As said, call Samsung. It is likely your TV does not have the hardware to decode video files, or may even use a different CPU system. The Series 9 firmware, at best will be rejected by the firmware upgrade routine, and at worst hose your set.1. Can software licenses be resold? [duplicate]Forget about selling your autodesk software, or buying used one.We bought autocad 2010 upgrade, and the activation failed because i registered the previous editions with a different name!I had to do several long calls to SWISS (of course, a money-making house like them, can be located somewhere else?) and mail them a copy of all the previous versions CD and boxes, with the invoices!!!! You can imagine what trouble can be finding the invoice of Autocad R14!!! (1998!!!)2. What is it like to be a software engineer with a PhD?There was no difference in general as most people did not know I had one. I did not actually think it was relevant. I took the degree because I wanted to enter teaching. When company started printing it in my calling card, the differences started to emerge. Most people started using the title and started asking for advice. Whenever I visited customers, the sales folk would start by introducing me as Doctor. Personally, I have always made decisions scientifically and like to measure and experiment. That I presume was a product of academic training3. How do you make software?First of all, you wo not be making any iPhone apps in the first couple years. With that said, I would advise learning an easy language, like BASIC or Pascal. There are lots of books on this subject4. Are US software patents enforceable in the UK?There are three main provision of the laws that might cause you problem and they all involve exporting to the US or encouraging others to do so. The primary statute on point is 35 U.S.C. 271(a)-(c).Thus, if you import an infringing product into the US or induce someone to import the infringing product into the US, then you can be held fully liable as an infringer. Even if you are selling through a third party distributor, you likely be seen as inducing the importation depending upon the facts. There is nothing illegal about selling to US customers when they are in the UK so long as that sale is not part of an import scheme.Now, there are some procedural issues that a patentee would need to overcome: (1) can a court get jurisdiction over you as a non-US entity; and (2) can they collect money damages since you are in the UK. These are big questions. If the case is brought in the US International Trade Commission (USITC) rather than in court then the court automatically claims jurisdiction based upon the imported products. The nice thing (for you) about USITC cases is that USITC never awards money damages (only awards exclusion orders to block further imports). If you lost a money judgment in court, the patentee could seize your US assets. There is no particular treaty between the US and UK on enforcing foreign money judgments. However, it is usually relatively simple for a US judgment winner to go to the UK and collect the money5. Illegal wiretapping software available to the public?because america is f*cked up and it seems invading privacy is "ok" when it involves some one you know. i say f*ck it all6. Most SEO friendly ecommerce software?Magento is the most SEO friendly, user friendly and customer friendly eCommerce solution. More than 40% of merchants are using magento for their ecommerce stores. There is no doubts magento is the best.7. What are some DVD Unprotecting software?I am a big fan of handbrake. DVD to MP4 in one easy step8. Regarding antivirus software such as AVG and Avast?AVG is just anti virus i think but theres free firewalls as well. the zone alarm one is good and maybe comodo. you might want some spyware software like windows defender as well.9. What do software architects do?I think the best (most practical and most accurate) definition of "architecture" is "what you think about when you think about your current problem in a usefully more abstract way". Or to put it another way, it can be an analogous to the old saying about winning the battle but losing the war. Programmers win the battles, architects win the war. Talking about software architecture is slippery, because the definition of software architecture itself is slippery and changes depending on who you ask, and when. One descriptor most people would agree with is "architects look at the bigger picture."At one end of the spectrum is a CTO or CIO to whom architecture is about which technologies and platforms the company should invest in. At the other end, even a regular Joe/Jane programmer thinks about how the pieces of the system they're working on go together.In between, that programmer's team might have an architect who spends his or her day making sure:that the team is taking the right general approach to solving the problem;that the different subsystems the programmers are working on will mesh well when they put them together;that the team is solving the right problem (depending on the culture and size of the organization this might be broken out into a different role).This might involve a lot of UML diagramming, or it might be more hands on and involve more discussions and whiteboarding, depending again on the culture and size of the organization. If it's a good software development group, I'd expect those discussions to involve project team members at all levels, but in more average groups there might be more formality and stricter lines of division, and the architect might spend most of their time with project managers, project planners, team leads, etc.In larger organizational contexts, frequently there's a lot of emphasis on formalisms to protect the rank and file workers from distractions. In smaller organizations, or sharper dev groups in larger organizations, it's easier to keep teamwork collaboration from becoming distraction (and sometimes easier to convince management that you know which is which). There might be an architect at the next level up who thinks about how the different enterprise systems work together.There's a term that sometimes comes up in software discussions, but surprisingly I don't think I've ever seen it in a discussion of architecture: cross-cutting concerns.Cross-cutting concerns are issues that cut across the entire application, like logging, security, how data gets around (message queues vs event listeners vs, etc), and sof orth. Programmers certainly think about these things and how they relate to the parts of the project they're working on. But it'd also be reasonable to say that cross-cutting concerns are (or are a good part of) the meat and drink of the architect.Also, as a slightly more obscure military saying goes, "privates study tactics, generals study logistics":The nature of the architect's role is such that he or she spends a lot of time dealing with all members and levels of the team, including the project planner, and the project manager (if they're not the same person). As I mentioned above, while I wouldn't be at all surprised if a given organization is very formal about the lines between areas of responsibility, I also wouldn't be at all surprised if it's the opposite - if the project manager and project architect and whoever else spent a lot of time not just liasing, but collaborating and kibbitzing. Hence the architect might also end up doing a lot of hands on stuff with project planning and software development methodology.(Note, where I write "programmer", insert your favorite title: developer, engineer, etc. Some people (and a few organizations) try to invent a hierarchy around these titles, but nobody seems to have the same definitions so the distinction is meaningless.)
