Primus AB
Primus AB is a manufacturer of portable cooking devices and outdoor stoves based in Stockholm, Sweden. History The firm was founded in 1892 by Frans Wilhelm Lindqvist and Johan Viktor Svenson. They were the developers of its initial product, the Primus stove, the first portable and soot-free kerosene stove. The first units were sold mainly to women who operated street market shops (stallholders) in Stockholm. Explorers then discovered the value in having a portable stove for their expeditions. For example, on Salomon August Andrée’s 1897 North Pole expedition, he cooked on a Primus. Roald Amundsen carried a Primus stove with him on his venture to the South Pole in 1911. And in 1953, Sir Edmund Hillary and Tenzing Norgay relied on Primus stoves during their first ascent of Mount Everest. Today, Primus stoves and lanterns are sold in over 70 countries. The stoves are made in Primus' factory in Tartu, Estonia. Ownership Primus AB is owned by Fenix Outdoor Internation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frans Wilhelm Lindqvist
Frans Wilhelm Lindqvist (1862 – 1931) was a Swedish inventor. He designed the first sootless kerosene stove, operated by compressed air. He started a company, Primus, to manufacture and sell the Primus stove. Lindqvist was born in Västergötland, and lived in Gothenburg for a few years before moving to Stockholm, where he started to work in the AB Separator factory. Inspired by a workmate, he and his brother were able to design a new kind of burner for kerosene stoves. By vaporising the kerosene before it reached the burner, their construction had a sootless, smokeless, hot flame. Lindqvist started selling his stove on a small-scale basis, but the business soon grew. The product and the company were dubbed Primus. Together with a companion, Johan Victor Svensson, Lindqvist started industrial production in 1892. With the help of marketing firm B.A. Hjorth & Co sales grew, and soon the Primus stove was exported abroad. In the 1910s, more than half a million stoves were ...

Tartu
Tartu is the second largest city in Estonia after the Northern European country's political and financial capital, Tallinn. Tartu has a population of 91,407 (as of 2021). It is southeast of Tallinn and 245 kilometres (152 miles) northeast of Riga, Latvia. Tartu lies on the Emajõgi river, which connects the two largest lakes in Estonia, Lake Võrtsjärv and Lake Peipus. From the 13th century until the end of the 19th century, Tartu was known in most of the world by variants of its historical name Dorpat. Tartu, the largest urban centre of southern Estonia, is often considered the "intellectual capital city" of the country, especially as it is home to the nation's oldest and most renowned university, the University of Tartu (founded in 1632). Tartu also houses the Supreme Court of Estonia, the Ministry of Education and Research, the Estonian National Museum, and the oldest Estonian-language theatre, Vanemuine. It is also the birthplace of the Estonian Song Festivals. Tar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camping Equipment Manufacturers
Camping is an outdoor activity involving overnight stays away from home, either without shelter or using basic shelter such as a tent, or a recreational vehicle. Typically, participants leave developed areas to spend time outdoors in more natural ones in pursuit of activities providing them enjoyment or an educational experience. The night (or more) spent outdoors distinguishes camping from day-tripping, picnicking, and other similarly short-term recreational activities. Camping as a recreational activity became popular among elites in the early 20th century. With time, it grew in popularity among other socioeconomic classes. Modern campers frequent publicly owned natural resources such as national and state parks, wilderness areas, and commercial campgrounds. In a few countries, such as Sweden and Scotland, public camping is legal on privately held land as well. Camping is a key part of many youth organizations around the world, such as Scouting, which use it to teach both sel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Fuel
Diesel fuel , also called diesel oil, is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel. Therefore, diesel fuel needs good compression ignition characteristics. The most common type of diesel fuel is a specific fractional distillate of petroleum fuel oil, but alternatives that are not derived from petroleum, such as biodiesel, biomass to liquid (BTL) or gas to liquid (GTL) diesel are increasingly being developed and adopted. To distinguish these types, petroleum-derived diesel is sometimes called petrodiesel in some academic circles. In many countries, diesel fuel is standardised. For example, in the European Union, the standard for diesel fuel is EN 590. Diesel fuel has many colloquial names; most commonly, it is simply referred to as ''diesel''. In the United Kingdom, diesel fuel for on-road use is c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jet Fuel
Jet fuel or aviation turbine fuel (ATF, also abbreviated avtur) is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is colorless to straw-colored in appearance. The most commonly used fuels for commercial aviation are Jet A and Jet A-1, which are produced to a standardized international specification. The only other jet fuel commonly used in civilian turbine-engine powered aviation is Jet B, which is used for its enhanced cold-weather performance. Jet fuel is a mixture of a variety of hydrocarbons. Because the exact composition of jet fuel varies widely based on petroleum source, it is impossible to define jet fuel as a ratio of specific hydrocarbons. Jet fuel is therefore defined as a performance specification rather than a chemical compound. Furthermore, the range of molecular mass between hydrocarbons (or different carbon numbers) is defined by the requirements for the product, such as the freezing point or smoke point. Kerosene-type jet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Gas
Coleman fuel, also generically sold as white gas, is a petroleum naphtha product marketed by the Coleman Company. Contents Historically called ''white gas'', it is a liquid petroleum fuel (100% light hydrotreated distillate), composed of cyclohexane, nonane, octane, heptane, and pentane. White gas was originally simply additive-free gasoline. This formulation is now rarely found. Coleman fuel, and its white gas copies, contain additives for inhibiting rust, ease of lighting, and fast burning. It is also cleaner than the original white gas. Use Coleman fuel is used primarily for fueling lanterns and camp stoves. It is usually sold in one-gallon cans in the United States; in Europe it is usually sold in one-litre bottles. Additionally, it is a popular fuel for fire dancing. Originally, it was simply casing-head gas or drip gas, which has similar properties. Drip gas was sold commercially at gas stations and hardware stores in North America until the early 1950s. The white ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Backpacking (wilderness)
Backpacking is the outdoor recreation of carrying gear on one's back, while hiking for more than a day. It is often an extended journey, and may involve camping outdoors. In North America tenting is common, where simple shelters and mountain huts, widely found in Europe, are rare. In New Zealand, hiking is called tramping and tents are used alongside a nationwide network of huts. Hill walking is an equivalent in Britain (but this can also refer to a day walk), though backpackers make use of a variety of accommodation, in addition to camping. Backpackers use simple huts in South Africa. Trekking and bushwalking are other words used to describe such multi-day trips. Backpacking as a method of travel is a different activity, which mainly uses public transport during a journey which can last months. Definition Backpacking is an outdoor recreation where gear is carried in a backpack. This can include food, water, bedding, shelter, clothing, stove, and cooking kit. Given that back ...

Liquified Petroleum Gas
Liquefied petroleum gas (LPG or LP gas) is a fuel gas which contains a flammable mixture of hydrocarbon gases, specifically propane, propylene, butylene, isobutane and n-butane. LPG is used as a fuel gas in heating appliances, cooking equipment, and vehicles. It is increasingly used as an aerosol propellant and a refrigerant, replacing chlorofluorocarbons in an effort to reduce damage to the ozone layer. When specifically used as a vehicle fuel, it is often referred to as autogas or even just as gas. Varieties of LPG that are bought and sold include mixes that are mostly propane (), mostly butane (), and, most commonly, mixes including both propane and butane. In the northern hemisphere winter, the mixes contain more propane, while in summer, they contain more butane. In the United States, mainly two grades of LPG are sold: commercial propane and HD-5. These specifications are published by the Gas Processors Association (GPA) and the American Society of Testing and Materi ...

Mount Everest
Mount Everest (; Tibetan: ''Chomolungma'' ; ) is Earth's highest mountain above sea level, located in the Mahalangur Himal sub-range of the Himalayas. The China–Nepal border runs across its summit point. Its elevation (snow height) of was most recently established in 2020 by the Chinese and Nepali authorities. Mount Everest attracts many climbers, including highly experienced mountaineers. There are two main climbing routes, one approaching the summit from the southeast in Nepal (known as the "standard route") and the other from the north in Tibet. While not posing substantial technical climbing challenges on the standard route, Everest presents dangers such as altitude sickness, weather, and wind, as well as hazards from avalanches and the Khumbu Icefall. , over 300 people have died on Everest, many of whose bodies remain on the mountain. The first recorded efforts to reach Everest's summit were made by British mountaineers. As Nepal did not allow foreigners ...
