Envirofit
Envirofit International is an American non-profit organization. It develops technology which aims to reduce air pollution and enhance energy efficiency among developing nations. Among its products have been affordable clean burning stoves for poorer communities. It is based in Fort Collins, Colorado, Envirofit was founded in 2003 by Tim Bauer, Nathan Lorenz, Paul Hudnut, and Bryan Willson. History Envirofit International began in 2003 as an adjunct program to the Colorado State University Engines and Energy Conversion Laboratory. The program's goals were to bring sustainable clean energy solutions to help solve health and energy challenges on a global scale. The first product was a retrofit direct injection technology to reduce pollution from two-stroke cycle vehicle engines in the Philippines. This project won the Rolex Award for Enterprise in 2008. In 2007, Envirofit partnered with the Shell Foundation's Breathing Space Program to develop clean cooking stoves. They were des ...

Gasoline Direct Injection
Gasoline direct injection (GDI), also known as petrol direct injection (PDI), is a fuel injection system for internal combustion engines that run on gasoline (petrol) which injects fuel directly into the combustion chamber. This is distinct from manifold injection systems, which inject fuel into the intake manifold (inlet manifold) where it mixes with the incoming airstream before reaching the combustion chamber.. The use of GDI can help increase engine efficiency and specific power output as well as reduce exhaust emissions. The first GDI engine to reach production was introduced in 1925 for a low-compression truck engine. Several German cars used a Bosch mechanical GDI system in the 1950s, however usage of the technology remained rare until an electronic GDI system was introduced in 1996 by Mitsubishi for mass-produced cars. GDI has seen rapid adoption by the automotive industry in recent years, increasing in the United States from 2.3% of production for model year 2008 ...

Stove
A stove or range is a device that generates heat inside or on top of the device, for - local heating or cooking. Stoves can be powered with many fuels, such as natural gas, electricity, gasoline, wood, and coal. Due to concerns about air pollution, efforts have been made to improve stove design. Pellet stoves are a type of clean-burning stove. Air-tight stoves are another type that burn the wood more completely and therefore, reduce the amount of the combustion by-products. Another method of reducing air pollution is through the addition of a device to clean the exhaust gas, for example, a filter or afterburner. Research and development on safer and less emission releasing stoves is continuously evolving. Etymology Old English had a word ''stofa'', meaning a hot-air bath or sweating room. However, this usage did not survive, and the word was taken newly from Middle Low German or Middle Dutch in the 15th or 16th century, later meaning any room heated with a furnace. By the ...

Air Pollution
Air pollution is the presence of substances in the Atmosphere of Earth, air that are harmful to humans, other living beings or the environment. Pollutants can be Gas, gases like Ground-level ozone, ozone or nitrogen oxides or small particles like soot and dust. It affects both outdoor air and indoor air. Natural sources of air pollution include Wildfire, wildfires, Dust storm, dust storms, and Volcanic eruption, volcanic eruptions. Indoor air pollution is often Energy poverty and cooking, caused by the use of biomass (e.g. wood) for cooking and heating. Outdoor air pollution comes from some industrial processes, the burning of Fossil fuel, fossil fuels for electricity and transport, waste management and agriculture. Many of the contributors of local air pollution, especially the burning of fossil fuels, also cause greenhouse gas emissions that cause climate change, global warming. Air pollution causes around 7 or 8 million deaths each year. It is a significant risk factor for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fuel Injection Systems
A fuel is any material that can be made to react with other substances so that it releases energy as thermal energy or to be used for work. The concept was originally applied solely to those materials capable of releasing chemical energy but has since also been applied to other sources of heat energy, such as nuclear energy (via nuclear fission and nuclear fusion). The heat energy released by reactions of fuels can be converted into mechanical energy via a heat engine. Other times, the heat itself is valued for warmth, cooking, or industrial processes, as well as the illumination that accompanies combustion. Fuels are also used in the cells of organisms in a process known as cellular respiration, where organic molecules are oxidized to release usable energy. Hydrocarbons and related organic molecules are by far the most common source of fuel used by humans, but other substances, including radioactive metals, are also utilized. Fuels are contrasted with other substances or de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economy And The Environment
An economy is an area of the Production (economics), production, Distribution (economics), distribution and trade, as well as Consumption (economics), consumption of Goods (economics), goods and Service (economics), services. In general, it is defined as a social domain that emphasize the practices, discourses, and material expressions associated with the production, use, and management of resources. A given economy is a set of processes that involves its culture, values, education, technological evolution, history, social organization, political structure, legal systems, and natural resources as main factors. These factors give context, content, and set the conditions and parameters in which an economy functions. In other words, the economic domain is a social domain of interrelated human practices and transactions that does not stand alone. Economic agents can be individuals, businesses, organizations, or governments. Economic transactions occur when two groups or parties agr ...

Engineers Without Borders
The term Engineers Without Borders (EWB; , ISF) is used by a number of non-governmental organizations in various countries to describe their activity based on engineering and oriented to international development work. All of these groups work worldwide to serve the needs of disadvantaged communities and people through engineering projects. Many EWB national groups are developed independently from each other, and so they are not all formally affiliated with each other, and their level of collaboration and organizational development varies. The majority of the EWB/ISF organizations are strongly linked to academia and to students, with many of them being student-led.Uzair M.

Poverty Line
The poverty threshold, poverty limit, poverty line, or breadline is the minimum level of income deemed adequate in a particular country. The poverty line is usually calculated by estimating the total cost of one year's worth of necessities for the average adult.Poverty Lines – Martin Ravallion, in The New Palgrave Dictionary of Economics, 2nd Edition, London: Palgrave Macmillan The cost of housing, such as the renting, rent for an apartment, usually makes up the largest proportion of this estimate, so economists track the real estate market and other housing cost indicators as a major influence on the poverty line. Individual factors are often used to account for various circumstances, such as whether one is a parent, elderly, a child, married, etc. The poverty threshold may be adjusted annually. In practice, like the definition of poverty, the official or common understanding of the poverty line is significantly higher in developed country, developed countries than in developi ...
