The problems for electric cars, there are many problems why peoples still can´t use quiet and more green cars. But even the electric car is not all green because the electricity produced for nuclear, coal, oil shale and natural gas. These ways to get electricity pollutes nature, the only difference between lies in the fact that pollution is in the one place.

and using a hybrid car. They do make a statement by being compact and fuel efficient, but also carry various issues. Why to purc has e a hybrid c ar? 1. Made of lightweight materials hybrids are small in size. The engine is designed to be fuel efficient. When the car halts at a signal, the engine will automatically shut down and restart when the car shifts into gear. 2. These cars have the advantage of being powered by a gasoline engine and an electric motor that takes care of acceleration. 3. The batteries of the electric motor recharge automatically by harnessing the kinetic energy produced during braking. 4. Hybrid car engines produce less emission, give better mileage, idle less, and are fuel efficient. Why to purc has e a hybrid c ar? 5. The aerodynamic design reduces drag and the tires are made of a special rubber that reduces friction. 6. The battery has high capacity and is made of nickel-metal-

charging. Both superchargers and turbochargers do this. The difference between the two devices is their source of energy . TURBOCHARGER When people talk about race cars or high-performance sports cars, the topic of turbochargers usually comes up. Turbochargers also appear on large diesel engines. A turbo can significantly boost an engine's horsepower without significantly increasing its weight, which is the huge benefit that makes turbos so popular! . In fact, the term "turbocharger" is a shortened version of "turbo-supercharger," its official name. The turbocharger is bolted to the exhaust manifold of the engine. The exhaust from the cylinders spins the turbine, which works like a gas turbine engine. The turbine is connected by a shaft to the compressor, which is located between the air filter and the intake manifold. The compressor pressurizes the air going into the pistons.
often crucial in human development.Kenya has the world's highest household solar ownership rate with roughly 30,000 small (20100 watt) solar power systems sold per year. Some renewable energy technologies are criticised for being intermittent or unsightly, yet the market is growing for many forms of renewable energy. Climate change concerns coupled with high oil prices, peak oil and increasing government support are driving increasing renewable energy legislation, incentives and commercialization. New government spending, regulation, and policies should help the industry weather the 2009 economic crisis better than many other sectors. Costs Renewable energy systems encompass a broad, diverse array of technologies, and the current status of these can vary considerably. Some technologies are already mature and economically competitive (e.g

At the same year were the first sketches of Mini made and after that the Mini model is been created from wood and also the most important mechanical parts for Mini has been developed. Four years later the Mini hits the streets. In 1965 the first Mini with an automatic transmission enters the market and in 1969 Mini gets itself an own badge. In 1971 Mini was the best-selling British car in the world. 1994 BMW group bought the Mini and year after that Mini was voted as the best car of the century by the car magazine readers in the UK and four years later Mini earned the same award in Europe. In 1998 the Mini was listed in the Guinness Book of Records as the Britain's most successful car. For now Mini has three different types of models: hatch, clubman and convertible. Mini is still owned by BMW Group. (www.mini.co.uk A) External marketing evironment analysis Socio-cultural Socio-cultural factors
changes drastically. And as a side effect new uses could be found in everyday life, not to mention the advancement in spacecraft related research. The purpose of this essay is to explain what a railgun is and how it works along with a little history and the recent advancements in railgun related science. 3 1. What a railgun basically is A railgun is an electrically powered electromagnetic projectile launcher and a large electric circuit, made up of three parts: a power source, a pair of parallel rails and a moving armature. Along the pair of parallel conducting rails a sliding armature is accelerated by the electromagnetic effects of a current that flows down one rail, into the armature and then back along the other rail. Railguns have long existed as experimental technology but the mass, size and cost of the required power supplies have prevented railguns from becoming practical military weapons.
a movement of atmospheric air masses that causes the earths wind system. If wind strikes over the surface of an open water, waves are induced. First they are very flat with only a low level of energy. When there is a long distance over the water on which wind can attack the small ones, they became bigger and bigger with a lot of energy inside them. Physics of wave energy To have a better understanding of the technical possibilities to harvest the energy out of waves to convert it into electric energy it may be helpful to have a look onto the physics of wave formation, the forces which attack and the characteristics of water waves. Wave formation There are three different momentum responsible for the formation of waves. The moon, earthquakes and wind in variable intensities. Energy of waves vs. period and responsible momentum 2 Three forces to attack the waves There are three forces that are responsible for wave formation. Two of them
For me this report is a great challenge because I have not done anything like this before, especially in English. Primary goal for me is to improve my knowledge about renewable energy and also usage of English language. This report is going to talk about biogas. It provides a brief review of usage and future prospects of the biogas. I have tried to make this report as understandable as possible. By the end of this report I want to come to a conclusion whether biogas is the best source of future energy or are there any other sources that are better. What is biogas? Typically it refers to the gas produced by the anaerobic digestion or fermentation of organic matter including manure, sewage sludge, municipal solid waste, biodegradable waste. If opportunely refined it can be used for electricity production. Also for space-, water- or process heating. Unintentional production of biogases has been an ongoing issue in many regions of
Word of these new amazing weapons quickly spread around the world and soon rockets were being used in military operations in North Africa and Europe. During the 15 th and 16th centuries they were widely used in naval battles to set fire on enemy ships. Around this time they also started being used for more peaceful purposes again. In the 16th and 17th century Europe fireworks displays using rockets became a very popular form of public entertainment. In the late 18th century the British army suffered two serious defeats at battles in Seringapatam, in India. The main reason for these defeats was that the Indian prince, Haidar Ali's army included a corps of rocket throwers. They used very large bamboo rockets which had a range of hundreds of metres. The British were determined to learn from their mistakes and a British officer, William Congrieve, began work on developing even bigger and better rockets

Wedgwood and Sir Humphry Davy who was a British scientists began their experiments to obtain photographic images, but these photos weren’t permanent because after exposing them to light the paper turned black. The first camera that was small enough to be portable was designed by Johann Zahn in 1685.The first cameras were similar to the Zahn model, but with improvements in focus since before each exposure a sensitized plaque was inserted. In 1839 was published the popular daguerreotype by Louis Daguerre’s which used silver-plated copper plates sensitized with iodine vapors The invention of the wet collodion wet plate process invented by Frederick Scott Archer in 1850 greatly reduced the exposure time but But it always required the photographer to craft the plates either in dark rooms of photographic studios or in portable laboratories. 6 How did it work? (HIGUERA) The scene was captured with a camera obscura focused onto a 16.2 cm × 20.2 cm (6.4 in × 8

Under surface pressure and temperature conditions, lighter hydrocarbons methane, ethane, propane and butane occur as gases, while pentane and heavier ones are in the form of liquids or solids. However, in an underground oil reservoir the proportions of gas, liquid, and solid depend on subsurface conditions and on the phase diagram of the petroleum mixture. An oil well produces predominantly crude oil, with some natural gas dissolved in it. Because the pressure is lower at the surface than underground, some of the gas will come out of solution and be recovered (or burned) as associated gas or solution gas. A gas well produces predominantly natural gas. However, because the underground temperature and pressure are higher than at the surface, the gas may contain heavier hydrocarbons such as pentane, hexane, and heptane in the gaseous state. At surface conditions these will condense out of the gas to form natural gas condensate, often shortened to condensate
So, the British ports are ice-free and its rivers are not frozen throughout the year. The weather on the British Isles has a bad reputation. It is very changeable and fickle. The British say that there is a climate in other countries, but we have just weather. If you don't like the weather in England, just wait a few minutes. It rains very often in all seasons in Great Britain. Autumn and winter are the wettest. The sky is usually grey and cold winds blow. On the average, Britain has more than 200 rainy days a year. The English say that they have 3 variants of weather: when it rains in the morning, when it rains in the afternoon, and when it rains all day long. Sometimes it rains so heavily, that they say «It's raining cats and dogs». Britain is known all over the world for its fogs. Sometimes fogs are so thick that it's impossible to see anything within a few meters. The winter fogs of London are, indeed, awful; they surpass all imagination
bricks are fired as they move slowly through the kiln on conveyors, rails, or kiln cars, which achieves a more consistent brick product. The bricks often have lime, ash, and organic matter added, which accelerates the burning process. Dry pressed bricks (slide 10) The dry press method is similar to the soft mud brick method, but starts with a much thicker clay mix, so it forms more accurate, sharper-edged bricks. The greater force in pressing and the longer burn make this method more expensive. Extruded bricks (slide 11) For extruded bricks the clay is mixed with 20% water. This mixture is forced through a die to create a long cable of material of the desired width and depth. This mass is then cut into bricks of the desired length by a wall of wires. Most structural bricks are made by this method as it produces hard, dense bricks, and suitable dies can produce holes or other perforations as well. The introduction of such holes reduces the volume of clay needed, and hence the cost.
in the world that occupies an entire continent. The mainland covers an area of 7.7 million km² and it is about 3700 km from the most northern point to its most southern point and about 4000 km from east to west. There are also many different seas around Australia, like the Coral and the Tasman Seas in the west or the Timor and the Arafura Seas in the north, where the Indian and the Pacific Oceans meet. Because all seas and oceans near Australia are warm, surfing is a very popular hobby. Political subdivision Australia is divided into six states, which are: · New South Wales · Victoria · Queensland · South Australia · Western Australia · Tasmania New South Wales is the most populous state in Australia. Its capital is Sydney. Victoria is one of the most densely populated states in Australia. Its capital city is Melbourne and it was named after the British Prime Minister Lord Melbourne. Melbourne is said to be
There are few multi- family houses with central heating and it is expensive to build DH networks in built areas. Most French DH systems are operated according to long-term concessions by companies that sell electricity and gas. No strong actor provides unbiased DH support. In the Czech Republic, gas offers DH severe competition. Much DH is produced at the expense of electricity that is considered more valuable, and waste incineration is not popular. In Romania, DH consumption was reduced by one-half. Distribution losses are enormous. New less polluting plants are needed. Consortia from established DH countries could offer DH systems from fuel to customer if local policies facilitate DH development. Introduction This paper describes barriers to district heating (DH) in various parts of Europe and to Swedish involvement in district-heating business abroad. The paper is based on a report called "District
One of the most common security issue was privacy related. It appears that 90% of the tested devices collected at least one piece of personal information [3]. Due to the variety of tasks the devices connected to the IoT monitor and administer, the amount of information to extract from those devices is fairly large. A british IT-consultant discovered that the LG made smart-TV has been sending back information to the company, about what shows the viewer has been watching and even what files are stored in the USB disk connected to the TV, without the user’s proper consent [4]. By collecting the data from just a smart TV, you could by long-term surveillance, form a pattern which tells you at what days and times a person watches television. From those times, you could deduce when a person is at work, when he is at home, on which days he doesn’t work, at which time does he go to sleep, which shows and topics interest him the most and so forth.
alternative, Sunbutter, especially in China, the United States, the Middle East and Europe. In Russia it is probably the most wide spread snack.[citation needed] It is also sold as food for birds and can be used directly in cooking and salads. Sunflower oil, extracted from the seeds, is used for cooking (but is less cardiohealthy than olive oil), as a carrier oil and to produce biodiesel, for which it is less expensive than the olive product. During the 18th Century, the use of sunflower oil became very popular in Europe, particularly with members of the Russian Orthodox Church because sunflower oil was one of the few oils that was not prohibited during Lent. The cake remaining after the seeds have been processed for oil is used as a livestock feed. Some recently developed cultivars have drooping heads. These cultivars are less
least whether it turned out cornflakes or Cadillacs. The restructuring of human work and association was shaped by the technique of fragmentation that is the essence of machine technology. The essence of automation technology is the opposite. It is integral and decentralist in depth, just as the machine was fragmentary, centralist, and superficial in its patterning of human relationships. The instance of the electric light may prove illuminating in this connection. The electric light is pure information... It is a medium without a message, as it were, unless it is used to spell out some verbal a ad or name. This fact, characteristic of all media, means that the " Intent"_ of any medium is always .another medium. The content of writing is speech, just as the written word is the content of print, and print is the content of the telegraph. If it is asked, "What is the content of speech?," it is necessary to say, "It is an actual process of thought,
animals are often strikingly lifelike and artistic. Many of these ancient relics have been destroyed by the ravages of nature and of man. Wind and water have worn away and continue to wear away, unprotected sites. And the paintings and carvings are increaslibly falling victim to vandalism: they have been painted over, spoilt with knives, even used for target practice. The American Rock Art Research Association protects rock-art sites. 2) THE FAVOURITE SPORT IN BRITAIN The most popular sport is probably football. Two kinds of football is played in Great Britain. One of them, which is called association football, is played all over Europe. The other kind: rugby football is also very popular in New Zealand, France, and some other European countries. English boys play it at school, and in public parks. When they grow up, they play as members of important amateur teams or as a professional in teams competing in football ,,leagues". Professional football is as much a business
Introduction The United States of America is a very big country. Its territory is about 9.4 million square kilometres and its population is more than 260 million people, 12% of them are the Afro-Americans. It is the world's third-largest country by size and by population. The population density is about 27 people per square kilometre. Most of the people live in towns. There are 50 states in America. The biggest of the state is Texas, next by size are California, Alaska and Montana. Six states - Maine, Vermont, New Hampshire, Connecticut ,Rhode Island and Massachusetts are called New England. They are all small states in the U.S

either from Britain or France. It was especially a poignant time for Africa, as then British Prime Minister Harold McMillan articulated his now famous “winds of change” sweeping Africa. We had high hopes for Africa, for the Black race, that the insidious imposition of foreign rule on us, the looting of Africa’s natural resources by our colonial masters accorded us would be things of history. That is more than forty years ago. Unfortunately, the promise of independence has not been fulfilled. Today, Africa has become more desolate; there is more starvation, diseases and non-provision of essential services than when we got our independence. There are all kinds of wars in Africa than the rest of world put together. The majority of so-called Africans leaders want to stay in power until the day their bodies are put in the grave
Country by country this idea started to spread. Active people in many countries have joined to clean up their countries in one day. In Latvia (210,000), Lithuania (250,000), Portugal (100,000), Slovenia (270,000), Romania (250,000), Albania (147,000), Hungary (200,000), Bulgaria (375,000), Ukraine (500,000), India (54,000), the Philippines (28,000) and in many other countries massive Let’s Do It! cleanups for a clean planet have been taking place. With more than 100 countries on board we have set ourselves a new challenge – to join the world for a massive cleanup day in 2018. On September 15, 2018, World Cleanup Day, people in 150 countries will stand up against the global trash problem and clean up waste, making it the biggest positive civic action the world has seen. Imagine a powerful “green wave” starting in Japan and ending in Hawaii with hundreds of millions of people taking positive action together on the very same day.

bookbinding. The people who worked in making books were called Warraqin or paper professionals. The Arabs made books lighter--sewn with silk and bound with leather covered paste boards, they had a flap that wrapped the book up when not in use. As paper was less reactive to humidity, the heavy boards were not needed. The production of books became a real industry and cities like Marrakech, Morocco, had a street named Kutubiyyin or book sellers which contained more than 100 bookshops in the 12th century; the famous Koutoubia Mosque is named so because of its location in this street. In the words of Don Baker: The world of Islam has produced some of the most beautiful books ever created. The need to write down the Revelations which the Prophet Muhammad, may peace be upon him, received, fostered the desire to beautify the object which conveyed these words and initiated this ancient craft
Kingdom of Great Britain and Ireland. After the Irish War of Independence most of Ireland seceded from the Union, which then became the United Kingdom of Great Britain and Northern Ireland. The relatively limited variety of fauna and flora on the island is due to its size and the fact that wildlife has had little time to develop since the last glacial period. The high level of urbanisation on the island has contributed to a species extinction rate that is about 100 times greater than the background species extinction rate. 2 The History of the Great Britain The island was first inhabited by people who crossed over the land bridge from the European mainland. Traces of early humans have been found (at Boxgrove Quarry, Sussex) from some 500,000 years ago and modern humans from about 30,000 years ago. Until about 10,000 years ago, Great Britain was joined to Ireland, and as recently as 8,000 years ago it was joined to
