My Country Has Successfully Developed a New Type of Rechargeable Lithium Battery for Electric Vehicl

(Source: Baijiahao)

The ternary lithium battery used has an energy of 100kWh, a cruising range of 660km under working conditions, and a fast charging efficiency of 80% in 40 minutes. This is an introduction to Tesla model S in terms of battery life. The author is not to introduce its battery life, but to explain its battery situation. On October 30th, Professor Chaoyang Wang of the University of Pennsylvania and his team applied hot words and technology to the research of rechargeable batteries and successfully developed a fast-chargeable lithium battery.

This lithium battery can be charged 80% in less than 10 minutes, and can last 300KM to 400KM for electric vehicles. Professor Wang Chaoyang also said that this battery has a relatively long life. After 2500 recharges, it will only lose 8.3%, which is much lower than the standard set by the US Department of Energy.

Many people definitely think that such a fast charging technology that has just been completed in the laboratory will take at least one year or six months to be truly popularized. However, Professor Wang Chaoyang said that the technology used in this battery is already very mature, so this Batteries can actually be commercialized immediately. In other words, we will soon be able to buy them on the market or experience them on some devices that use electricity.

In fact, the EC power company founded by Professor Wang Chaoyang himself has commercialized this lithium battery, and this battery will also be used in the Beijing 2022 Winter Olympics.

Nowadays, the main energy used by people is petroleum, but after realizing that petroleum and diesel will damage the environment, they are also looking for other alternative energy sources. Electricity is one of the alternative energy sources and it has always been everyone's consensus. However, there has always been a contradiction between storage and use in the use of electric energy, which is often referred to as the problem of energy efficiency. This is particularly evident in electric vehicles, so the battery life of electric vehicles has always been a topic of concern.

People often give up a car that is more than 100,000 yuan cheaper because the battery of an electric car can support the car to travel a hundred kilometers. It can be seen that the endurance of an electric car has always been one of the important standards for the public to measure its quality. one.

However, with the development of this industry, people also thought of another solution, which is to set up more charging piles, and then charge as fast as possible. Therefore, the development of fast charging technology has also become a focus of people's attention. Now there is a battery with a charging efficiency four times that of Tesla's electric cars, which is naturally a big improvement in energy utilization.

The author can predict that with the development of charging technology, only in terms of electric vehicles, the internal batteries may become smaller and smaller. At that time, the development of electric vehicles will have more energy to study in other directions, such as Get a car that can change the internal structure according to your mind.

Why Are Companies Not Focusing on Thermal Batteries for Electric Vehicles & Instead, Doing More Rese
Why are companies not focusing on thermal batteries for electric vehicles & instead, doing more research on Li-ion batteries?Lithium Battery Chemistry is a proven, light weight and reliable chemistry. Only if some other chemistry comes up that is better in all aspects Vs Lithium, then only it will be considered. In the secondary batteries domain, it is the most superior chemistry as of now. Magnesium ion is in development. If it becomes safe enough and commercialized you will see a 2X growth in capacity of the batteries for the same size and much lower cost of manufacture— — — — — —Is there any technology in Li-ion batteries that was not available in the early 20th century?There are two posed questions here. On question 1, I agree with earlier answers on its possibility. Would it have been possible that someone like Edison (a well-funded inventor at that time working on batteries) could have tried Lithium instead of Lead and gotten a good result? No. While Edison could have tried using elemental Lithium, that is a long way from the final answer which uses intercalated Lithium. To get there we needed to postulate the theory of Fermi surfaces (1930's), discover how to make non-natural intercalation (1940's), and then discover Lithium ion intercalation (1970's) before being in a position to discover today's battery solution. On question 2, speculate on how a battery economy would be different from an internal combustion engine economy. The most obvious impact would have been that coal resources would have become more valuable relative to oil. The Middle East, Latin America, and South America have large oil reserves while North America, Russia, China, and India have large coal reserves.— — — — — —How will graphene change batteries?

You will find a recommended and a maximum charge rate. (The faster you charge them, the quicker they will die.)Then find and use a charger that can meet those specifications.Follow all warnings about keeping batteries in a fire proof container while you do.— — — — — —Are NiMh batteries less dangerous than Li-ion batteries?Yes, Nickel-Metal-Hydride (Ni-MH) batteries are relatively safer when compared to Lithium Ion batteries.This is because, they have a stable chemistry and no flammable electrolyte that can trigger an intense explosion or fire, when short circuited or overcharged. Over-discharging is not at all a concern except in few cases. Lithium Ion batteries are dangerous because overcharging or over-discharging or short circuiting them can result in production of heat that can ignite the flammable electrolyte. The electrolyte used is a liquid electrolyte that comprises Lithium Hexafluoro Phosphate (LiF6PO4) dissolved in Ethylene Carbonate solvent.However, this does not give us the permission to incorrectly handle the Ni-MH batteries. In case of elevated overcharging, the Metal Hydride that acts as the anode (negative terminal) can ignite and trigger a fire as the dissociated compound yields Hydrogen gas that can be ignited by the heat prevalent in the overcharging cell. This is only in case of high overcharging. A normal Ni-MH cell can be recharged till 1. 4 Volts whereas in case it is given 2 Volts or more, it can go up in flames.In case of short circuits, even household Ni-MH batteries can heat up so much that their wrappers can melt and the plastic casing holding them can also melt. It can inflict severe burns on the skin and sometimes ignite a flammable substance such as an aerosol spray. Avoid short circuits with any type of battery.

Those ICs have a lot in common and are described by the same datasheet. The details of the communication protocol are in the datasheet
Volvo have announced that from 2019, all their new vehicles will be partially or completely battery powered.Between 2019 and 2021 they will introduce 5 new cars which will be 100% electric. The rest of their range will be hybrids. This has been described as a key moment in the move towards a more environmentally friendly planet. The number of electric cars on the road globally hit 2 million in 2016, a considerable increase from previous years. And we can expect this number to grow exponentially, with expectations that electric cars might be outcompeting combustion engines by the mid-2020s.At this time, customer demand for electric vehicles is increasing, battery costs have come down, and there is an increasing movement to implementing the appropriate infrastructure. We can see this trend in the UK, and around the world. France is set to ban the sale of any car that uses petrol or diesel fuel by 2040 in a revolutionary move towards them becoming a carbon neutral country by 2050. Similarly, Norway and the Netherlands are keen to make the move to electric-only vehicles by 2025. In more immediate news, TfL recently announced an £18 million investment in to rapid charge points around the capital and Leeds have followed suit, with a £2 million subsidy from the government focused on getting electric vehicles on the road. A proportion of this is going towards rapid charge points for the taxi and private hire industry.The impact of this investment relies on the industry being receptive to these changes, and of course will not happen overnight. Electric cars are still not affordable for all, and until the infrastructure is in place, they will not be the most convenient modes of transport.So what does this mean for you?It is important to consider what electric cars would mean for your fleet. There are several clear advantages to having a 'green fleet'. Firstly, customers are often big advocates of environmentally friendly changes. Many are willing to pay more for a journey that will not harm the environment, so this can be a valuable selling point.But what about cost? The running costs of an electric car have always been low, it has just been the initial price which was off putting. However as their popularity soars, the cost is decreasing. In addition to this, governments sometimes offer incentives for low emission vehicles which can really make them worth your while.Practicality has also been a common concern. Having a fleet of electric cars in the last few years would have taken a significant amount of planning in regards to charging: the time it took, and the places where it can be done. However, as stated earlier, the country is making massive leaps forwards in both these areas. Charging points are becoming more commonplace throughout cities, and can charge a vehicle in only 30 minutes!Greenpeace have stated that 'we know electric cars are the future', and this trend is clear to see. It is not something you need to act on today, or even this year. But it is worth bearing in mind that these moves by Volvo and various governments are likely to be imitated by others. With the infrastructure improving, and car manufacturers getting in on the game, soon it may well be the time for you to invest in that electric car you've had your eye on.How much would a new Car Battery cost?Between 30 and 60 dollars at PePboys or Auto zone you can call and they will give a price .They will want ur core or the old battHow much should a new car battery cost?At my shop we stock Interstate batteries.

Even though China outlets are 220V and US outlets are 110V, I have no problems charging my shaver or my digital camera's Li-Ion battery in the factory charger or even using my laptop while plugged into a power strip.
A Battery That Could Revolutionize Electric Vehicles
Batteries are an integral part of everyday life. They are necessary for storing solar and wind power. They power portable electronic devices and are needed for traditional and hybrid cars. There are endless applications in our lives that involve batteries. In addition to the widespread use of batteries, scientists are also constantly looking for more sustainable ways to utilize energy. The importance of batteries inspires engineers to continually improve their design and performance. This includes the evolution of the lithium-ion battery.Issues with the batteryEngineering professor John Goodenough from the University of Texas was one of the inventors of the lithium-ion battery. However, it was soon discovered that the energy storage devices had the potential for exploding or bursting into flames. The problem lay in the liquid electrolytes the battery contained. When charged too quickly, metallic whiskers or dendrites formed in and passed through the electrolytes, which caused a short-circuit between the negative and positive terminals.Advances in battery designTo solve the dilemma, Goodenough and fellow researcher Maria Helena Braga replaced the electrolytes with glass electrolytes that function in combination with the alkali-metal terminals to provide power. The upgraded electrodes additionally enabled the battery to have up to three times the energy, which would last longer between charges. In addition to the glass electrolytes, Goodenough's new batteries use sodium in place of lithium in the cells.The devices also successfully functioned at temperatures of -4 degrees Fahrenheit or -20 degrees Celsius. Despite severely cold weather, the batteries would continue providing power to electronic devices or hybrid cars. Goodenough and his team continue researching battery development and are in the process of obtaining patents. They hope to soon work with manufacturers and further test their innovation.New batteryProfessor Michael Zimmerman from Tufts University recently introduced his version of the upgraded lithium-ion battery. He replaced the liquid electrolytes with flame-resistant plastic. In this way, regardless of what type of damage the battery might suffer, they will not explode or ignite. The unique batteries also have the ability to continue supplying power despite being damaged.The lithium ions created pass through the plastic, which is not susceptible to dendrite formation. The safety measure also enables the battery to have a metal negative post, which could increase the energy storage two-fold.Zimmerman formed the Ionic Materials company and successfully raised millions of dollars in order to manufacture and offer his battery for commercial purposes. However, Professor Zimmerman and his new company have as of yet to share when the batteries might become available.Originally published at on June 10, 2018·RELATED QUESTIONHow do I find cheap and reliable e-cigarette suppliers in China?Importing Electronic Cigarettes from ChinaElectronic cigarettes are one of the few products that could be considered a "home grown" product in China. Since the first units rolled off the assembly lines in Shenzhen about 10 years ago, the electronic cigarettes have presented itself as a serious alternative to smokers - that still want to take a puff now and then.However, e-cigarettes are still a topic of high level controversy, and regulations are still on the drawing board in both the US and EU. The product is also lethal - if not manufactured according to the relevant safety standards. Keep reading and we explain why.Electronic Cigarette Manufacturers in ChinaThere's only one place in the world to go if you're looking for electronics, the Guangdong province. Roughly 87% of the Electronic cigarettemanufacturers listedone-CantonFair.comre based here. Of these, the majority isbased in Shenzhen, a city bordering Hong Kong. But there are also quite a few suppliers located in Dongguan, Huizhou and Zhongshan - all of which are also based in Guangdong province.The industry jump started in 2010 and 2011 - when hundreds of new suppliers starting manufacturing and trading (that's two different things) electronic cigarettes. This was before most western government had yet reacted to the influx of this, still controversial, product. I'll get to that in a bit.A lot of suppliers caught on this trend and started trading electronic cigarettes, rather than manufacturing the product themselves. If you browse a site, you'll quickly notice that most suppliers are mere traders, with very little registered capital (ranging from RMB 30,000 to 100,000). Stay away from these suppliers. They can't offer a better price. They can rarely offer smaller volumes - and certainly not smaller volumes of electronic cigarettes that are compliant with EU andUS product certification standards. What they can offer is an extra, non-transparent, layer - between you and the actual manufacturer. A manufacturer you know nothing about.Components and Product SpecificationsThere's no universal definition of "good quality". Instead, you need to know what defines good quality. As with every product, there are certain features and parameters thatdefines the quality standardof an electronic cigarette. To begin with, there are 4 main categories of electroniccigarettes:1. Rechargeable Electronic Cigarettes2. Disposable Electronic Cigarettes (Non-Rechargeable)3. E-Go Electronic Cigarettes4. Personal VaporizersProduct specifications vary between the different types of electronic cigarettes. For example, you don't need to bother with E-liquid cartridges if you're purchasing Disposable Electronic Cigarettes. But there are still a number of common quality factors that buyers should take into consideration when selecting a product:· Cartridge Puffs: 200 - 500· Cartridge Capacity: 1.X ml· Child-proof spring switch: Yes / No· Body material:· Mouthpiece material:· LED: Yes / No· Charger type: USB· Battery Capacity: XXX mAh· Weight: XXg· Working voltage: 3.X - 3.X VBatteryMost suppliers can offer batteries of different capacities. It's a critical component, since the number of "puffs" is limited not only by the E-liquid, but also the battery capacity. The relation between the battery capacity and the number of "puffs" is something like this:· 650mah: 600-650 puffs· 900mah: 800-850 puffs· 1100mah:1000-1050 puffsThere's also a limit to the battery life. However, the battery shall be rechargeable at least 300 times.ChargerMost suppliers offer both USB chargers and Power socket chargers. I'd go for the USB charger. The voltage in a power socket is much higher than the voltage in a USB socket (around 5 V). An overloaded power socket charger can cause personal injury and outbreak of fire. I've seen it happen. On the other hand, an overcharged USB is likely to result in little more than a voltage drop or cut. That won't kill anyone or burn down a house.E-liquidsThe E-liquid, or E-juice, is the "active substance" in the electronic cigarettes and usually contains the following:· Propylene glycol· Vegetable glycerin· Nicotine· FlavoringsHowever, there's no set standard of what substances E-liquid shall contain, not to mention the content of each substance. This is also a current topic of debate among regulators around the world, particularly in the European Union and United States.In the European Union, the legal situation is more fragmented. So far, there's no EU wide product safety standard that applies specifically to electronic cigarettes. However, EU states have implemented their own regulations. As of today, it's legal to import and sell electronic cigarettes and liquids with nicotine in the following EU countries:· United Kingdom· Germany· Italy· Poland· Ireland· Latvia· LithuaniaStill, electronic cigarettes are still a topic of debate and further regulations are to be expected. This post could be outdated two weeks from now, so make sure youread up on the current regulationsbefore you import electronic cigarettes or e-liquids from China.In Australia, electronic cigarettes are regulated on a state level. Recently, Western Australia banned imports and sales of electronic cigarettes of all kinds. While imports are still legal for personal use, Australian importers better stay away from electronic cigarettes altogether.Product Certification RequirementsEven though regulations specifically for electronic cigarettes are still on the drawing board, in both Europe and America, that is not saying that product certification standards don't apply to the hardware. Electronic cigarettes are subject to certification standards regulating electronic products. These include the following:European Union· RoHS (Assembled product & individual components)· CE (Assembled product & individual components)· REACH (Mouthpiece & plastic case)Need a helping hand? When you order a Starting Package, we source Electronic cigarette suppliers able to show previous compliance, and guide you step-by-step through the whole ordering process. There are several reported casesof e-cigarettes exploding and catching fire. Keep in mind the importer is always held responsible, in case a product causes personal injury or property damage. Ensuring product certification compliance is always critical when importing from China.
What Automakers Aren't Telling You About Electric Vehicles ...
Will 2019 become the year of the electric car?At next month's auto show in Geneva, electric cars and concepts from Aston Martin's Lagonda marque, Nissan, Audi, Mercedes, Honda and Kia will take center stage.They'll join a growing list of cutting-edge electronic vehicles, or EVs, entering the increasingly crowded segment this year.The technology and design of these zero-emission vehicles has improved dramatically in recent years.But a vexing challenge remains: convincing consumers to give up their internal combustion engine (ICE) cars and trucks.Of the 17 million vehicles sold in the U.S. last year, 229,000, or 1.3 percent, were electric. Tesla's Model 3 sedan accounted for over half (138,000) of EV sales, dominating the nascent market."The new electric vehicles are aimed directly at Tesla," Ed Kim, vice president of industry analysis at AutoPacific, told ABC News. "The vast majority of them are in the Tesla price range. Tesla has real competitors."Jaguar, the British luxury automaker, introduced its challenger to Tesla last year: the all-electric I-Pace SUV. More than 600 units have been sold in the U.S. since last November, the first month of sales. Sleek and futuristic, with a minimalist, airy interior, the new $69,500 I-Pace is a departure from the British luxury carmaker's traditional gasoline-powered vehicles.To stay competitive in the fast-moving EV segment, Jaguar needed to act quickly. Doing so required major investments and extreme dedication. There was no other choice."This is brand new territory for us," David Larsen, Jaguar Land Rover's general manager of product development, acknowledged to ABC News. "The I-Pace was designed from the ground up."Unsurprisingly, the largest markets for the I-Pace are California, Florida and Texas – areas with warm year-round climates."Cold weather can cut range significantly – by even one third," Kim said. "Lithium ion batteries are subject to temperature sensitivity. In California this is not an issue. In polar vortex conditions, these vehicles wouldn't get far."The I-Pace, for example, gets as much as 234 miles from one full charge of its high-tech lithium ion battery, according to the EPA. That figure can shift significantly for reasons other than temperature. Heating or cooling the vehicle, how fast one drives and even radio usage can drain the battery.I-Pace customers can charge their vehicles at home with a wall-mounted Level 2 240-volt home EV charger. It takes nearly 13 hours for the high-voltage battery to get a full-charge when starting at zero percent. Connecting the I-Pace to a standard 120V electrical outlet with a cable also works; Jaguar estimates the SUV would get an extra 30 miles this way if charged overnight."The car is constantly optimizing battery efficiency," Larsen said. "The I-Pace learns how you drive and your driving behaviors to estimate what your range will be."Larsen, though, never has to charge his I-Pace at home. Jaguar's office in Mahwah, New Jersey, offers charging stations. But he acknowledged that "range anxiety" -- the fear of running out of battery charge on the road -- is real and owning an electric car can take some adjusting.Stable fuel prices in the U.S. have also slowed demand for these pricey vehicles, Kim explained."We are used to 5 minutes at the pump and going," he said. "It takes a long time to fill these things up. Faster charging will get us closer to the level of convenience with gasoline cars."Tesla's Model S made driving an electric car cool and trendy. Federal tax credits also helped move the needle for some drivers, though many EVs are purchased "by people who are not price sensitive," said Kim. Plus, the majority of EV owners are not die-hard environmentalists. Many Tesla owners are "technology enthusiasts," he noted.Teslas may be the EV of choice with Americans but the Nissan Leaf is the top-selling EV globally. And with more models on the horizon, these industry leaders may see their monopoly on the market shrink.Audi's e-tron SUV will begin deliveries to U.S. customers this spring. Porsche's much-anticipated Taycan electric sports car will be unveiled later this year. Mercedes Benz will soon roll out its EQC SUV, aimed at the e-tron. There will also be an all-electric Mini from BMW.Cadillac, GM's luxury brand, will be retooled to focus on electric cars. Volkswagen plans to invest $800 million to build a new electric vehicle at its plant in Tennessee."We'll continue to see more EVs come on the market," Kim said. "In the next three to four years, the market will be saturated with EVs. There will be a lot more supply than demand."There are two problems, however, that could put the brakes on the market expansion of EVs, according to Karl Brauer, executive publisher of Cox Automotive."They still cost a lot more than ICE cars and charging takes a long time," he told ABC News. "For a rancher in Montana, EVs are not the solution. These cars are for people who live in urban areas and don't travel more than 100 miles or more a week."Brauer, who has driven the I-Pace, said he was "fascinated" with the SUV at first -- until it was time to juice the battery."It doesn't charge as well as it should, even with a Level 2 charger," he said. "There were times when I thought it was charging but it wasn't. It has everything going for it and it drives extremely well. In terms of battery, I was disappointed."Driving an electric car also requires some patience and practice. They're built with regenerative brakes, allowing the vehicle to function with single pedal driving. When the driver lifts his or her foot off the accelerator, the car will come to a sudden stop, especially when the regen braking is set to high. The abruptness can be jarring and disorientating in the beginning."It's a different driving experience," Larsen admitted. "There's a steep learning curve. The first time I drove the I-Pace I had to turn off the regen braking. It felt weird."Automakers want consumers to believe that traditional cars are antiquated. In reality, an EV future is decades away."Electric cars are not mainstream yet," Kim said. "There's a lot of momentum building behind electrification, especially in Europe and Asia. Automakers will push them even though they're low volume vehicles. They need North American sales. Consumers have to buy into the advantages of having an EV."
What Are Some Ways to Keep My Hair Really Healthy?
What Are Some Ways to Keep My Hair Really Healthy?
Use professional shampoo & conditioner. I know it may seem like a rip-off, however all the shampoos like Pantene, Garnier, etc. have a high alcohol content....since the normal pH of your hair is 4.5-5.5, things containing high amounts of alcohol throw your hair all out of whack and cause breakage, split-ends, fly-aways, etc. The reason these shampoos make your hair feel soft is because they contain high amounts of humectants, which are just a cover for how damaging they really are! Another tip is ALWAYS use a thermal protector while applying heat. Heat appliances cause tons of damage to your hair. Usually this is a cream/clear gel you apply before blow drying. Never use a flat iron on hair that is not completely dry!1. Split End Help. ( 10 Points) !!!!!!!!!!!!!!!!!!!!!!?For sure you should get a trim and maybe even cut your hair as short as you are comfortable doing it. You should for no reason straighten or dye your hair. Look for some Garnier Fructis or Pantene shampoos and conditioner for curly hair so that it extra moisturizes it and helps the split ends repair themselves. I say from experience that ppl with curly hair have really bad split ends, which is why we have special stuff in our hair products. The split ends wont magically go away in like a month or a few weeks, but you will see improvement after a while. Oh, and for sure DO NOT PICK THEM OFF!! It will just make it worse. Every two months until your hair is healthy get a trim. just maybe half an inch or an inch will be just fine. Eventually your hair will go back to normal. Good luck with that!.2. Whats the best shampoo conditioner for cheap?clever or V05 are solid inexpensive ($a million) shampoos, yet whilst it is composed of conditioner i could bypass Tresemme ($6) it does an somewhat solid interest. i take advantage of salon shampoo because of the fact i am form of a hair snob, yet I nonetheless use the cheap conditioner. Pantene is undesirable on your hair (too plenty protein and reasons alot of greater build up on the hair) so i does not bypass there. desire this permits! My hair is oily, superb, and colour-taken care of if that helps you any!3. How can I get my curly hair to be nice like Taylor Swift?Haha i have the same hair long and curly..but not pretty curly! im completely obsessed with taylor and her hair so i did so playing with it and what you really NEED to get is the conair hot sticks!! they are these little flexible curlers and they are not very expensive and i would look like a frizz ball without them!! you can like get them at walmart. anyways what i do when iwear my hair curly is like i get up and get in the shower and wash it and condition it and this may sound weird but dont use a whole lot of conditioner just enough to get it done cause it will help your hair hold the curl the just get out and towel dry your hair till it is just damp and then put a curling mouse in it and frizz serum then finish blow drying it straight! and you know have the curlers on like when your gettin in the shower and then just make sure the little light is on meaning that they are hot enough and then seperate your hair into pretty small peices (if you have really thick hair then you might need to buy two sets cause they only have 14 in them and you use small sections) and then start from the botom of your hair and role it through your hair and pin it together youll see the instructions on how to pin them together and make sure you wrap it all the way to the top of your head and leave them for like 15 or 20 minutes while your finishin gettin ready and then use like a light hairspray about 5 minutes before you take them out then your done. i know this thing was really long but its not that hard lol!!!! hope i helped good luck!!!!!!!!

Huami Technology Held a Press Conference on August 27, and Amazfit Smart Sports Watch 3 Officially A
This morning, huami technology officially announced that it would hold the 2019 new product Conference on August 27. Then, Huang Wang, CEO of huami technology, posted the invitation letter for the new product Conference on his microblog. Huami technology distributed amazfit one-way wet guide short sleeved T-shirts and amazfit antelope running shoes to the media as physical invitations. The gift box vacated a watch position, which triggered extensive discussion in the media. Huang Wang also explained that this vacancy was actually reserved for the new amazfit intelligent movement watch 3.(invitation letter from Huang Wang, CEO of huami Technology)The theme of huami technology's 2019 new product launch is "run, amazfit! Run!", which is adapted from the classic line "run, Forrest! Run!" of Forrest Gump. With his pure love for sports, Forrest Gump, the protagonist in the film, runs across the United States. No matter how many difficulties and ridicules he encounters, he also doesn't give up. "Run, Forrest! Run!" is the symbolic line that Forrest Gump's mother encourages him, and Forrest Gump can persevere and succeed step by step. This spirit also inspires many people.

But, a google search for WEP cracking might point you in right direction, but no recommended to do so.— — — — — —How to network a house, both wireless and wired.?The best way would be to recreate the wired network, then set up a wireless network. Use a computer to bridge them together— — — — — —Is it possible to extend the range of your wireless network?You have a couple of different options at your disposal. One is getting higher dbi gain antennas for your ROUTER. The second is adding a higher gain dbi antenna to your adapter (optionally, you can do both and really extend the range). Another is getting a range extender. The higher dbi gain antenna plugged into your router and adapter can really extend your network. Without any obstructions, and 15 dbi gain antennas, you can connect at about 2 miles away. The range extender might be a little cheaper. It plugs into an electrical socket and you run an ethernet cable right into it. This is good if you have quite a few walls in between you and router. Not practical if you do not like wires, you would be better off with the antennas. Regards, Brandon— — — — — —Is it a good idea to download something from an unsecured network?If you see that a wireless network says it's "unsecured", this only means that that wireless network does not have a wireless password. Hence, you or anyone can readily connect to it without entering a password. There is minimal risk of you getting a virus just because of connecting to an "unsecured network", except probably if you go to a website or accidentally downloaded an email that has a virus attached to it - things of that sort. Another risk, although very negligible, is that other people who are connected to that same unsecured network may access your computer files given that you have set your computer files to be on SHARED mode. This is HARDLY ever the case, since you will need to grant that person permission via the Windows File Sharing application. So I tell you, it's okay.— — — — — —XBOX 360 WIRELESS NETWORK ADAPTER BYPASS?There are a number of possible solutions here, but they all depend on you having existing hardware that would cost significantly more than the adapter. Firstly, if you have/buy one of the new "slim" xbox 360s, they have wireless built in, so no need for an adapter. Second, if you have a computer connected to the internet near the 360, you can use the laptop as a wireless receiver, then run an ethernet (CAT5) cable from the laptop to your 360. Thirdly, if you have a computer nearby that is connected by a wired connection (cables through the roof etc) then you can use that computer as a router, and plug the xbox into the computer to share connection. If you just have an xbox 360 original in a room that has no wired connection or a computer connected to wireless, your only option is to buy the adapter.— — — — — —Problems with Wireless Network internet connectionWich encryption type do you use?

Is Time Travel Possible? Can We Travel Back in Time?
Is Time Travel Possible? Can We Travel Back in Time?
There is no actual "correct." Einstein made a "theory," not a fact. If Einstein's theory is correct, we could theoretically travel back in time but the problem is, we would not be able to go into the future1. What's the similarities between time travel and space travel?The faster your motion through space relative to a stationary reference frame, the more your motion is diverted from your motion through time. In other words, in a very specific sense, we move through time at lightspeed. The faster you move through space, the more your movement through time is diverted by your movement through space. At lightspeed, all your motion through time is diverted by your motion through space. A photon does not experience time. All of its motion through time is diverted by its motion through space. According to relativity theory anyway2. How to travel with cats?Some cats do fine being loose in the car. Try taking them for a little ride (5-10 minutes) and see how they react. I had one cat, a wonderful loving tabby, that I took for a car ride. I was not driving, so she crawled into my lap, squalled, and peed all over my lap! Some years later I had 3 Siamese, and drove from Wisconsin to Montana with them loose in the car, without a bit of a problem. I think its great that you are taking your cats along with you!!!3. Is it Cheap to Travel to Trinidad?It all depends on where you are flying from. If you are in the US it might be better for you to go to Miami. For me in the Caribbean, I would definitely go to Trinidad because the fair is cheaper, the prices are not that bad, I know my way around and I would feel safe. I can just go down town and buy a few doubles and just watch the people go buy sitting on the side of the road. You might not want to do that. I might even buy some shark and bake. Generally, I go to Chaguanas and shop but I might just stay in POS. From the time I take to spend that extra money to go to Miami I could stop right here in Trinidad. I have been there many times and I have not have a problem. It is up to you though because my experiences might be different to yours. All you have to do is to stay where there is lots of people and the same precautions you would take in your country take there. Do not walk around with your purse expose because that would be asking for trouble.4. Is it safe to travel to Israel?Of course it's safe. It's safer than the US. all that stuff you hear is media bullS5. Where to travel in Europe?You can visit Norway :)6. How do I learn about mountain bikes?Firstly, size. Also, go and have a look at a few of their bikes, there is an interesting rating system next to the bikes, indicating the type of riding that it is suitable for. Next, using 1 - 10 scale. But this is based upon components, layout and value for money. MBR is a good place to do some research. For general bike buying, it is advisable to stick to some of the bigger brands. Trek, Scott, Giant, Specialized. You might also consider some of the smaller manufacturers like Claude Butler or Dawes. For components use either SRAM or Shimano gears. Cranks, either Shimano or Truvative, although if you want to throw money at this you could easily look at 2 - 300 on Race Face or Hollowtec. However, many manufacturers use their own brand, eg. Bontager = Trek. However, if you stick with the brands listed above, they will use viable kit, it just depends how much money that you want to spend on your bike. Hard tail or full sus? Firstly, do not spend less than 700 on a full sus. Do not buy an all singing, all dancing 200 bike from Walmart, Tesco, Cycleking, etc. Hard tails tend to be lighter. Also, because you are not spending huge amounts on a rear shock, you get better quality components elsewhere. So, spending 700 on a hardtail will get you a nice race machine with good quality components and viable suspension. You will still get a nice full sus for this price, but the overall quality will not be as high. If you are just hitting well maintained gravel tracks and roads, you do not want your front fork to do too much, so 80mm travel is good. This is also good if you want to race, since you lose less forward power to bouncy forks. For general XC, about 100mm fork travel, although an adjustable fork between 80 and 130 mm is OK. Any fork that starts at 120mm travel will tend to fall into the all mountain category. These will have chunkyer tyres than XC and are better for bounlders and logs etc. Downhill will have a lot of travel up front, with a raked back design. Luck
