Hobo Stove
A hobo stove is a style of improvised heat-producing and cooking device used in survival situations, by backpackers, hobos, tramps and homeless people. Hobo stoves can be functional to boil water for purification purposes during a power outage and in other survival situations, and can be used for outdoor cooking. Construction and uses This stove may be built from a discarded tin can of any size by removing the top of the can, punching several small holes near the upper edge, and a larger opening on the side of the can near the bottom, for fuel and air. The bottom of the can is generally left in place, as this yields a stronger stove structure and minimizes spread of fire to combustible material on the ground. Fuel is placed in the can and ignited. Convection draws air in through the bottom/side orifice, and heat emerges from the top. A cooking vessel may be placed on the top. The bottom/side hole may face the wind for more heat or it may be partially covered with scrap metal i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cooking Potatos On A Large Hobo Stove 04
Cooking, cookery, or culinary arts is the art, science and craft of using heat to prepare food for consumption. Cooking techniques and ingredients vary widely, from grilling food over an open fire to using electric stoves, to baking in various types of ovens, reflecting local conditions. Types of cooking also depend on the skill levels and training of the cooks. Cooking is done both by people in their own dwellings and by professional cooks and chefs in restaurants and other food establishments. Preparing food with heat or fire is an activity unique to humans. Archeological evidence of cooking fires from at least 300,000 years ago exists, but some estimate that humans started cooking up to 2 million years ago. The expansion of agriculture, commerce, trade, and transportation between civilizations in different regions offered cooks many new ingredients. New inventions and technologies, such as the invention of pottery for holding and boiling of water, expanded cooking techni ...

Isopropyl Alcohol
Isopropyl alcohol (IUPAC name propan-2-ol and also called isopropanol or 2-propanol) is a colorless, flammable organic compound with a pungent alcoholic odor. As an isopropyl group linked to a hydroxyl group (chemical formula ) it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms. It is a structural isomer of propan-1-ol and ethyl methyl ether. It is used in the manufacture of a wide variety of industrial and household chemicals and is a common ingredient in products such as antiseptics, disinfectants, hand sanitizer and detergents. Well over one million tonnes is produced worldwide annually. Properties Isopropyl alcohol is miscible in water, ethanol, and chloroform as, like these compounds, isopropyl is a polar molecule. It dissolves ethyl cellulose, polyvinyl butyral, many oils, alkaloids, and natural resins. Unlike ethanol or methanol, isopropyl alcohol is not miscible with salt solutions and ...

Swedish Torch
A Swedish torch (also Swedish candle, Finn candle, Swedish fire, Siberian tree torch or Russian tree torch; ) is a source of heat and light from a vertically set tree trunk, incised and burning in the middle. It became known in Europe during the 1600s and is now used by forest workers, and for leisure activities (especially in southern Germany). Due to its flat surface and good embers, it can also be used for cooking. Compared to a campfire, it is more compact, and therefore several small heat sources can be distributed over an area. Oral tradition attributes the development of the torch to the Swedish military during the Thirty Years' War; using a saw or hacksaw or an axe, the Swedes are said to have made burning and glowing logs to warm their soldiers. This method of providing heat meant that their troops did not have to carry their own firewood with them but were able to get supplies on site, as the freshly cut, green wood can burn due to the chimney effect. Manufacture an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket Stove
A rocket stove is an efficient and hot burning stove using small-diameter wood fuel. Fuel is burned in a simple combustion chamber containing an insulated vertical chimney, which ensures almost complete combustion prior to the flames reaching the cooking surface. Rocket stove designs are most often used for portable stoves for cooking but the design is also used for large, fixed stoves in institutions, and to make rocket mass heaters for heating. In field tests in India, rocket stoves used 18 to 35 percent less fuel, compared to the traditional stoves, and reduced fuel used 39-47 percent, compared to the simple, traditional, open, three-stone fire. History A precursor to the rocket stove was the Argand lamp, which was patented in 1780. This was a major development of the traditional oil lamp, which introduced a glass chimney above the flame to increase air-flow. As well as being used for lighting, this design was also used for cooking and for heating water due to its "affo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portable Stove
A portable stove is a cooking stove specially designed to be portable and lightweight, used in camping, picnicking, backpacking, or other use in remote locations where an easily transportable means of cooking or heating is needed. Portable stoves can be used in diverse situations, such as for outdoor food service and catering and in field hospitals. Since the invention of the portable stove in the 19th century, a wide variety of designs and models have seen use in a number of different applications. Portable stoves can be broken down into several broad categories based on the type of fuel used and stove design: unpressurized stoves that use solid or liquid fuel placed in the burner before ignition; stoves that use a volatile liquid fuel in a pressurized burner; bottled gas stoves; and gravity-fed "spirit" stoves. History Early example The shichirin, a lightweight charcoal stove, has been used in Japan in much the same form since at least the Edo period (1603-1868). Old shic ...

List Of Stoves
This is a list of stoves. A stove is an enclosed space in which fuel is burned to provide heating, either to heat the space in which the stove is situated, or to heat the stove itself and items placed on it. Stoves are generally used for cooking and heating purposes. Stoves * Aprovecho – Aprovecho Research Center has worked on designs for cook stoves, primarily for use in developing countries. They are best known for the Rocket stove, developed by their technical director Dr. Larry Winiarski. * Bachelor griller – a countertop kitchen appliance with which a single person can grill, bake, boil or roast small portions of food * Bamboo stove – an historical stove made in China in the late 14th century, it included bamboo to form the frame of the stove. The sides were cemented with clay and the inside walls and the ring on top were iron. It was about a foot tall. * Beverage-can stove – a homemade, ultralight portable stove. The simple design is usually made entirely from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Improved Cookstove
One aspect of energy poverty is lack of access to clean, modern fuels and technologies for cooking. As of 2020, more than 2.6 billion people in developing countries routinely cook with fuels such as wood, animal dung, coal, or kerosene. Burning these types of fuels in open fires or traditional stoves causes harmful household air pollution, resulting in an estimated 3.8 million deaths annually according to the World Health Organization (WHO), and contributes to various health, socio-economic, and environmental problems. A high priority in global sustainable development is to make clean cooking facilities universally available and affordable. Stoves and appliances that run on electricity, liquid petroleum gas (LPG), piped natural gas (PNG), biogas, alcohol, and solar heat meet WHO guidelines for clean cooking. Stoves that burn biomass more efficiently than traditional stoves are known as "improved cookstoves", and are an important interim solution in areas where deploying cleaner t ...

Beverage-can Stove
A beverage-can stove, or pop-can stove, is a do it yourself, ultralight, alcohol-burning portable stove. It is made using parts from two aluminium beverage cans. Basic designs can be relatively simple, but many variations exist. Total weight, including a windscreen/stand, can be less than one ounce (28 g). The design is popular in ultralight backpacking due to its low cost and lighter weight than commercial stoves. This advantage may be lost on long hiking trips, where a lot of fuel is packed, since alcohol has less energy per gram than some other stove fuels. Of the available fuels, methanol delivers the least energy, isopropyl alcohol delivers more, butanol is hardly ever used, and pure ethanol the most. Denatured alcohol and rubbing alcohol are frequently used for this purpose, as it often contains a mixture of ethanol and other alcohols. All but isopropyl alcohol burn with a smokeless flame; it can provide both light and heat. History and design The basic design dat ...

Carcinogen
A carcinogen is any substance, radionuclide, or radiation that promotes carcinogenesis (the formation of cancer). This may be due to the ability to damage the genome or to the disruption of cellular metabolic processes. Several radioactive substances are considered carcinogens, but their carcinogenic activity is attributed to the radiation, for example gamma rays and alpha particles, which they emit. Common examples of non-radioactive carcinogens are inhaled asbestos, certain dioxins, and tobacco smoke. Although the public generally associates carcinogenicity with synthetic chemicals, it is equally likely to arise from both natural and synthetic substances. Carcinogens are not necessarily immediately toxic; thus, their effect can be insidious. Carcinogens, as mentioned, are agents in the environment capable of contributing to cancer growth. Carcinogens can be categorized into two different types: activation-dependent and activation-independent, and each nature impacts their ...

Wood Preservation
Wood easily degrades without sufficient preservation. Apart from structural wood preservation measures, there are a number of different chemical preservatives and processes (also known as "timber treatment", "lumber treatment" or "pressure treatment") that can extend the life of wood, timber, and their associated products, including engineered wood. These generally increase the durability and resistance from being destroyed by insects or fungi. History As proposed by Richardson, treatment of wood has been practiced for almost as long as the use of wood itself. There are records of wood preservation reaching back to ancient Greece during Alexander the Great's rule, where bridge wood was soaked in olive oil. The Romans protected their ship hulls by brushing the wood with tar. During the Industrial Revolution, wood preservation became a cornerstone of the wood processing industry. Inventors and scientists such as Bethell, Boucherie, Burnett and Kyan made historic developments in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bisphenol A
Bisphenol A (BPA) is a chemical compound primarily used in the manufacturing of various plastics. It is a colourless solid which is soluble in most common organic solvents, but has very poor solubility in water. BPA is produced on an industrial scale by the condensation of phenol and acetone, and has a global production scale which is expected to reach 10 million tonnes in 2022. BPA's largest single application is as a co-monomer in the production of polycarbonates, which accounts for 65–70% of all BPA production. The manufacturing of epoxy resins and vinyl ester resins account for 25–30% of BPA use. The remaining 5% is used as a major component of several high-performance plastics, and as a minor additive in PVC, polyurethane, thermal paper, and several other materials. It is not a plasticizer, although it is often wrongly labelled as such. The health effects of BPA have been the subject of prolonged public and scientific debate. BPA is a xenoestrogen, exhibiting ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerosene
Kerosene, paraffin, or lamp oil is a combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in aviation as well as households. Its name derives from el, κηρός (''keros'') meaning " wax", and was registered as a trademark by Canadian geologist and inventor Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. The term kerosene is common in much of Argentina, Australia, Canada, India, New Zealand, Nigeria, and the United States, while the term paraffin (or a closely related variant) is used in Chile, eastern Africa, South Africa, Norway, and in the United Kingdom. The term lamp oil, or the equivalent in the local languages, is common in the majority of Asia and the Southeastern United States. Liquid paraffin (called mineral oil in the US) is a more viscous and highly refined product which is used as a laxative. Paraffin wax is a waxy solid extracted from ...
