As the demand for mobile computing and all-electric cars increases, the limitations of current battery technology presents a roadblock. Invented in the 1790s by Italian physicist Alessandro Volta, the electric battery has been the workhorse of numerous gadgets, devices, and machines.

As consumer devices have become smaller and their uninterrupted use before recharging more important, it has also become increasingly important for batteries to become both miniaturized and more energy efficient. This, however, has proved to be a technological hurdle that, if surpassed, will be an important and profitable development for tomorrow's high tech economy.

Battery Technology
All electrical batteries rely on the fundamental chemical reaction of reduction and oxidation …show more content…
Lithium-air (Li-Air) batteries are an exciting new development that could allow for much greater energy storage capacity – up to 10 times more capacity than a typical LiOn battery. These batteries would literally "breathe" air by using free oxygen to oxidize the anode. While this technology seems promising, there are a number of technological problems, including a quick build-up of performance-decreasing byproducts and the problem of "sudden death" in which the battery ceases to work without warning.

Lithium-metal batteries are also an impressive development, promising nearly four times more energy efficiency than the current electric car battery technology. This type of battery also is much less expensive to produce, which will bring down the cost of products that use them. Safety issues, however, are a major concern as these batteries can overheat, cause fire, or explode if damaged. Other new technologies being worked on include lithium-sulfur and silicon-carbon, but these cells are still in the early phases of research and are not yet commercially viable.

Greenwashing

...Essay Outline A3 Jackie Introduction 1. Background “Greenwashing” is what companies or organizations do when they spend more time claiming to be “green” through advertising and marketing than actually implementing business practices that minimizes environmental impacts ( Berkeley Media Studies Group, 2008). In recent decades, due to the increasing pressure from the government and public regarding the environmental issues, a growing number of companies are using “greenwashing” strategies to boost their sales (Berkeley Media Studies Group, 2008) and carmakers are no exception. With gas prices on everyone’s mind as well as individuals’ concern about environment, people are looking for clean and fuel-efficient cars to go easy on the environment and their wallets. As a result, some car manufacturers launched hybrid cars with biopower engines which gained popularity soon and labeled themselves as environmentally friendly companies. 2. Identification of problem Saab, one of world-renowned car manufactures, innovatively launched a new style of car, Saab 9-5 in 2007 which used biopower engine. This writer selects Saab for the essay. Saab’s environmental claims are that “The Saab 9-5 2.0t BioPower is not only kind to the environment; it also produces more power and performance than its gasoline equivalent” (Coman, 2006). 3. Thesis Statement This essay will explain why “greenwashing” has become a growing problem, examine two environmental claims made by Saab and demonstrate that...

Now, when it comes to transportation by using electricity and magnetism, which is the focus of my essay, there is an exponential room to grow. In the near future, electricity and magnetism is going to revolutionize our transportation system radically. The most important issues facing our world in the future in regard to transportation is reducing the amount of emission caused by an ever increasing usage of transportation and our dependence on it. Not only emission is going to be the focal point of problems caused by transportation but also reducing the number of vehicles driven by people will be at the heart of our future struggles too. As historians and energy scientists noted dully, as societies advance more and more, they are going to use more concentrated forms of energy, for example, instead of gasoline they are going to use rocket fuel. In regard to transportation, cars are leading the way when it comes to electric use. In not so distant future, I expect cars to use more than half of their energy consumption from electricity. Right now, electric cars for propulsion, they use the energy stored in a battery. Just like anything in the world, there are many pros and cons when it comes to electric cars, for example even if electric cars produce no exhaust but they also require long...

...development of wireless endoscopy are he as an electo-optical engineer and was working on developing the “eye” of guided missile to its target. His friend at boston gave him information about technology used for viewing the interior lining of the digestive system which had lots of limitations, specially with viewing the small intestine. This small intestine causes serious disorders and only in United States approximately 19 million people suffer from disorders. Existing technology like X-ray and endo-scopes were unable to identify or investigate about small intestine. So the only option left was surgery and which was very crucial if the physician does not know which part of the small intestine is affected. So his friend encourages him to come up with better technology. Due to technology revolution after decade small video cameras which uses image sensors like CCDS (Charge coupled devices) has been developed. With his knowledge from developing the eye of guided missile he tried to make small missile like device which could travel through the intestine without a life line leading to the outside of the body and transmit images wirelessly to a receiver outside of the body. He has also done small experiment on chicken with his developed camera and as he succeeds he got more encouragement but he found battery of that camera get exhausted in few minutes. So he developed a prototype CMOS (complementary metal oxide semiconductors) which only consume a fraction of power then CCD and applied for...

Still, this is connected to a myriad of issues and peculiarities to be considered, and some scientists believe that technological advancement makes such conundrums inevitable (Cavanaugh, 2006). As modern lifestyles become more efficient and more complicated, people seek ways to apply technology to mundane activities in order to simplify these tasks. According to Professor Brian Nejmeh (2012), the acquisition of knowledge needs to be in tandem with current technological trends. One of the spheres having the rifest debates about implementing technologies is education. Among several radical proposals concerning this question was a blanket ban on textbooks in favor of laptops, which resulted in controversy reaching its peak. The general cost of buying a laptop and maintaining it is higher as compared to school textbooks.

Hybrid Vehicles

...hybrid automobiles have begun to take a more prominent role in the automobile industry. “Historically, many in the automobile and oil industries have fought progress on electric cars. It's the same story we've seen before with seat belts and catalytic converters: The automakers leave the technology on the shelf until policymakers require them to do what is in the best interests of the American people.” (Anair & Shahan, 20011). Policy will dictate how the industry will be impacted over the next five years. Lawmakers are constantly changing the rules and regulations that automakers have to produce cars by. In the following essay we will use a macro trend analysis to determine the path of the hybrid vehicle. Issues Legislation has evolved over recent years requiring automakers to adhere to a minimum fuel economy standard. As gas prices continue to rise, people have started to trend toward more energy efficient means of transportation. Hybrid vehicles have an electric motor along with rechargeable batteries and have an increased efficiency of up to 50 percent. There is an onboard computer that switches between gas and electric power. The hybrid car runs on the energy of the battery when it is cruising, using less energy. When it needs additional power, the fuel engine is used for energy purposes. The market for hybrids can be analyzed by looking at the macro-environmental trends (macro trends). According to Mullins and Walker (2010), “the macro-environment...

Solar Energy Is an Excellent Source of Alternative Energy

...Environmental Safe In recent decades scientists have considered the use of solar energy as an application of alternative energy sources. For many years solar energy is considered an outstanding worldwide energy source. Solar energy and solar power are two different terms. Solar power is converting sunlight into electricity. “The potential of solar energy with technologies and the reductions in climate changes could provide most of the worlds energy by 2060 according to IEA report in 2011.” Solar energy is an excellent source of alternative energy because it is renewable, it is economical, and it is environmental safe. This essay describes several features that categorize solar energy as an excellent source of energy and discusses the advantages and disadvantages of solar energy. Solar energy derives its power from the sun radiation striking the earth. Not all sunlight reaches the earth surface. Yet that which is received is more than the human species need to sustain life. The energy of the sun radiation that is deposit in our region of North America is sufficient. Solar energy is a renewable energy source as well. With technology, the cost to install solar panels outweighs the cost of producing coals, oil and gas. The amount of solar radiation- sunlight deposited on the surface of the earth is enough power for the whole world. [2] Solar energy is sustainable. Can we ever over-consume? Harnessing solar energy generally does not cause pollution. The small amount of emissions from...

...“If you build it they will come” fails for turtle crossings By Sarah Zelinski | 1    |      It’s really too bad that turtles can’t read. | 2    |      If they did, it would make saving them so much easier. When people create an ecopassage1 so the reptiles can safely cross a road by going underneath or over it, they could let the animals know with little signs saying “Don’t become roadkill! Safe crossing, left 20 meters.” | 3    |      Instead, we have to rely on fencing to keep the turtles and snakes off roads, which is a good idea because 98 percent or more of turtles are killed in their first attempt at a road crossing. But the reliance on fences may be a problem, a new study shows. When there aren’t effective fences to keep the reptiles out, they don’t use the ecopassages, James Baxter-Gilbert of Laurentian University in Sudbury, Ontario, and colleagues report March 25 in PLOS ONE. | 4    |      The study looked at the effectiveness of a series of ecopassages built along a 13-kilometer stretch of Highway 69/40 near Burwash, Ontario, near Lake Huron, a region with high reptile biodiversity. The passages ran beneath the highway and were paired with fencing along the road. The researchers looked at reptile activity along the roadway before and after the project was constructed, and also used another stretch of highway, near the Magnetawan First Nation, as a comparison. | 5    |      They surveyed the roadside and put up cameras in the ecopassages to see what kind...

Hybrid Cars

...3/17/2011 Efficiency of Hybrid cars Have you been to the gas station lately? Have you been shocked with the high fuel prices? When the price went beyond $40 or higher you must have thought for a second to trade in your SUV for a car with a better gas mileage, or you even might have thought about global warming. The car industry has found a technology that has an answer for these questions. The answer is the hybrid car. Most of the big car manufacturers have a hybrid model on the market. You might have heard about some or even seen some driving down the street already. Hybrid cars work differently than other cars, they are made differently than other cars, they perform differently than other cars and they are more efficient than other cars. How does a hybrid car work? What is it that a hybrid car is so much more efficient than a normal car, and is it really better for the environment because the gas mileage is so much better? In this essay I want to explain how this amazing technology called hybrid car works. What makes a car a hybrid car? Every vehicle is a hybrid when it uses two or more energy sources. In fact, a lot of people have owned or still own a hybrid. For example, an electronic bike is a hybrid because it combines the power of an engine with the force that comes from people using the pedals. Hybrid vehicles are everywhere around us. A lot of diesel locomotives pulling trains are diesel-electric hybrids. In cities like Seattle, they use diesel-electric busses...

In this small essay, I will be picturing myself in four different scenarios placed in different timelines in the future. First, I will picture myself in 2020, four years and two months from now, making a telephone call. The second hypothetical scene, I will picture myself in 2025 doing a homework assignment. The third scenario, I will place myself in 2050 eating a meal with my family. The forth scenario, I will picture myself almost 100 years from now in 2125 doing a homework assignment. With these scenarios I will use the technique, futuring, to image myself in the future and explain each setting. Now, what would happen if I, at the age I am now, was in the year 2020? What would happen if I were to make a phone call in 2020? Phones then have become foldable. You can place them in your pockets with very little cases with cracked phones from their convenient folding ability. Though, only five years from now, folding with some major phone upgrades are the only prevalent ideas with phones. The problem is that with these foldable phones, battery life has become a very heavy issue with foldable phones because the battery cannot exceed past the foldable dimensions of each phone. So what would happen in 2025, ten years from now in the future while doing homework? I honestly do not believe that in 10 years...
