Incinerating Toilet
An incinerating toilet is a type of dry toilet that burns human feces instead of flushing them away with water, as does a flush toilet. The thermal energy used to incinerate the waste can be derived from electricity, fuel, oil, or liquified petroleum gas. They are relatively inefficient because of the fuel used. History The first commercially successful incinerating toilet was the Destroilet, patented in 1946. Destroilets were used on ships in the 1960s when laws were passed to prevent the dumping of raw sewage into American waterways. In 2011, the Bill & Melinda Gates Foundation launched the "Reinvent the Toilet Challenge" to promote safer, more effective ways to treat human excreta. Several research teams have received funding to work on developing toilets based on solid waste combustion. For example, a toilet under development by RTI International is based on electrochemical disinfection and solid waste combustion. This technology converts feces into burnable pieces and ...

Dry Animal Dung Fuel
Dry dung fuel (or dry manure fuel) is animal feces that have been dried in order to be used as a fuel source. It is used in many countries. Using dry manure as a fuel source is an example of reuse of human excreta. A disadvantage of using this kind of fuel is increased air pollution. Types Dry dung and moist dung Dry dung is more commonly used than moist dung, because it burns more easily. Dry manure is typically defined as having a moisture content less than 30 percent. Dung cakes "Dung cakes", made from the by-products of animal husbandry, are traditionally used as fuel in India for cooking food in a domestic hearth called a Chulha. They are made by hand by village women and are traditionally made from cow or buffalo dung. One dung cake of an average size gives 2100 kJ of energy. Dung cakes are also known as ''goitha'', ''uple'', ''kande'', ''gosse'' or ''thepdi''. These are the cakes of cow dung molded by bare hands with a curvature to keep them stuck to the walls. ...

Caravan (towed Trailer)
A caravan, travel trailer, camper, tourer or camper trailer is a trailer towed behind a road vehicle to provide a place to sleep which is more comfortable and protected than a tent (although there are fold-down trailer tents). It provides the means for people to have their own home on a journey or a vacation, without relying on a motel or hotel, and enables them to stay in places where none is available. However, in some countries campers are restricted to designated sites for which fees are payable. Caravans vary from basic models which may be little more than a tent on wheels to those containing several rooms with all the furniture and furnishings and equipment of a home. Construction of the solid-wall trailers can be made of metal or fiberglass. Travel trailers are used principally in North America, Europe, Australia and New Zealand. The word ''caravan'' (sometimes ''trailer caravan'' in distinction to ''motor caravan'') is regional to Great Britain, while in North Americ ...

Recreational Vehicle
A recreational vehicle, often abbreviated as RV, is a motor vehicle or trailer that includes living quarters designed for accommodation. Types of RVs include motorhomes, campervans, coaches, caravans (also known as travel trailers and campers), fifth-wheel trailers, popup campers, and truck campers. Typical amenities of an RV include a kitchen, a bathroom, and one or more beds. RVs can range from utilitarian – containing only sleeping quarters and basic cooking facilities – to luxurious, with features like air conditioning (AC), water heaters, televisions and satellite receivers, and quartz countertops. Types RVs can be either trailers that are towed by vehicles or vehicles that can be driven themselves. Most RVs have one level, but there are also some with two levels. To save space while traveling, larger RVs often have slide-outs or canopies that open up when parked. RVs that can be driven can be categorized "motorhomes", which will have the engine in front ...

Mobile Home
A mobile home (also known as a house trailer, park home, trailer, or trailer home) is a prefabrication, prefabricated structure, built in a factory on a permanently attached chassis before being transported to site (either by being towed or on a trailer). Used as permanent homes, or for holiday or temporary accommodation, they are often left permanently or semi-permanently in one place, but can be moved, and may be required to move from time to time for legal reasons. Mobile homes share the same historic origins as travel trailers, but today the two are very different, with travel trailers being used primarily as temporary or vacation homes. Behind the cosmetic work fitted at installation to hide the base, mobile homes have strong trailer frames, axles, wheels, and tow-hitches. History In the United States, this form of housing goes back to the early years of cars and motorized highway travel. It was derived from the travel trailer (often referred to during the early year ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackwater (waste)
Blackwater in a sanitation context denotes wastewater from toilets which likely contains pathogens that may spread by the fecal–oral route. Blackwater can contain Human feces, feces, urine, water and toilet paper from flush toilets. Blackwater is distinguished from greywater, which comes from sinks, baths, washing machines, and other household appliances apart from toilets. Greywater results from washing food, clothing, dishes, as well as from showering or bathing. Blackwater and greywater are kept separate in "ecological buildings", such as autonomous buildings. Recreational vehicles often have separate holding tanks for greywater from showers and sinks, and blackwater from the toilet. Definition According to one source: Water coming from domestic equipment other than toilets (e.g., bathtubs, showers, sinks, washing machines) is called greywater. In some sanitation systems, it is preferred to keep the greywater separate from blackwater to reduce the amount of water that ...

Barge
A barge is typically a flat-bottomed boat, flat-bottomed vessel which does not have its own means of mechanical propulsion. Original use was on inland waterways, while modern use is on both inland and ocean, marine water environments. The first modern barges were pulled by tugs, but on inland waterways, most are pushed by Pusher (boat), pusher boats, or other vessels. The term ''barge'' has a rich history, and therefore there are many types of barges. History of the barge Etymology ''Barge'' is attested from 1300, from Old French ''barge'', from Vulgar Latin ''barga''. The word originally could refer to any small boat; the modern meaning arose around 1480. ''Bark'' "small ship" is attested from 1420, from Old French ''barque'', from Vulgar Latin ''barca'' (400 AD). A more precise meaning (see Barque) arose in the 17th century and often takes the French spelling for disambiguation. Both are probably derived from the Latin ''barica'', from Greek language, Greek ''baris'' "Eg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yacht
A yacht () is a sail- or marine propulsion, motor-propelled watercraft made for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with a cabin intended for overnight use. To be termed a , as opposed to a , such a pleasure vessel is likely to be at least in length and may have been judged to have good aesthetic qualities. The Commercial Yacht Code classifies yachts and over as . Such yachts typically require a hired crew and have higher construction standards. Further classifications for large yachts are : carrying no more than 12 passengers; : solely for the pleasure of the owner and guests, or by Flag#At sea, flag, the country under which it is registered. A superyacht (sometimes ) generally refers to any yacht (sail or power) longer than . Racing yachts are designed to emphasize performance over comfort. Charter yachts are run as a business for profit. As of 2020, there were more than 15,000 yachts of sufficient size ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Septic Tank
A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater (sewage) flows for basic sewage treatment. Settling and anaerobic digestion processes reduce solids and organics, but the treatment efficiency is only moderate (referred to as "primary treatment"). Septic tank systems are a type of simple onsite sewage facility. They can be used in areas that are not connected to a sewerage system, such as rural areas. The treated liquid effluent is commonly disposed in a septic drain field, which provides further treatment. Nonetheless, groundwater pollution may occur and is a problem. The term "septic" refers to the Anaerobic digestion, anaerobic bacterial environment that develops in the tank that decomposes or mineralizes the waste discharged into the tank. Septic tanks can be coupled with other Onsite sewage facility, onsite wastewater treatment units such as biofilters or aerobic systems involving artificially forced aeration. T ...

Pathogen
In biology, a pathogen (, "suffering", "passion" and , "producer of"), in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a Germ theory of disease, germ. The term ''pathogen'' came into use in the 1880s. Typically, the term ''pathogen'' is used to describe an ''infectious'' microorganism or agent, such as a virus, bacterium, protozoan, prion, viroid, or fungus. Small animals, such as helminths and insects, can also cause or Transmission (medicine), transmit disease. However, these animals are usually referred to as parasites rather than pathogens. The scientific study of microscopic organisms, including microscopic pathogenic organisms, is called microbiology, while parasitology refers to the scientific study of parasites and the organisms that host them. There are several pathways through which pathogens can invade a host. The principal pathways have different episodic time ...

Natural Gas
Natural gas (also fossil gas, methane gas, and gas) is a naturally occurring compound of gaseous hydrocarbons, primarily methane (95%), small amounts of higher alkanes, and traces of carbon dioxide and nitrogen, hydrogen sulfide and helium. Methane is a colorless and odorless gas, and, after carbon dioxide, is the second-greatest greenhouse gas that contributes to global climate change. Because natural gas is odorless, a commercial odorizer, such as Methanethiol (mercaptan brand), that smells of hydrogen sulfide (rotten eggs) is added to the gas for the ready detection of gas leaks. Natural gas is a fossil fuel that is formed when layers of organic matter (primarily marine microorganisms) are thermally decomposed under oxygen-free conditions, subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other ...

Dry Toilet
A dry toilet (or non-flush toilet, no flush toilet or toilet without a flush) is a toilet which, unlike a flush toilet, does not use flush water. Dry toilets do not use water to move excreta along or block odors. They do not produce sewage, and are not connected to a sewer system or septic tank. Instead, excreta falls through a drop hole. A variety of dry toilets exist, ranging from simple bucket toilets to specialized incinerating and freezing toilets. Types Types of dry toilet, listed in approximate order from simplest to most complex, include: * Bucket toilet – The most basic kind of toilet. May have a toilet seat, with or without a lid. May be accompanied by material (e.g. wood ash, sawdust, or quick lime) to cover excreta after use. * Pit latrine – excluding pour-flush versions with water seal * Urine-diverting dry toilet – urine and feces collected separately * Composting toilet ** Arborloo – shallow pit latrine designed for making compost ** Treebog – ...
