Kerosene, or paraffin, 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 κηρός (kērós) meaning "wax", and was registered as a trademark by Nova Scotia geologist and inventor Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage.
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways.
Lighting or illumination is the deliberate use of light to achieve practical or aesthetic effects. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants.
A kerosene lamp is a type of lighting device that uses kerosene as a fuel. Kerosene lamps have a wick or mantle as light source, protected by a glass chimney or globe; lamps may be used on a table, or hand-held lanterns may be used for portable lighting. Like oil lamps, they are useful for lighting without electricity, such as in regions without rural electrification, in electrified areas during power outages, at campsites, and on boats. There are three types of kerosene lamp: flat-wick, central-draft, and mantle lamp. Kerosene lanterns meant for portable use have a flat wick and are made in dead-flame, hot-blast, and cold-blast variants.
A lantern is an often portable source of lighting, typically featuring a protective enclosure for the light source – historically usually a candle, a wick in oil, or a thermoluminescent mesh, and often a battery-powered light in modern times – to make it easier to carry and hang up, and make it more reliable outdoors or in drafty interiors. Lanterns may also be used for signaling, as torches, or as general light-sources outdoors.
A flashlight or electric torch, usually shortened to torch, is a portable hand-held electric lamp. Formerly, the light source typically was a miniature incandescent light bulb, but these have been displaced by light-emitting diodes (LEDs) since the early 2000s. A typical flashlight consists of the light source mounted in a reflector, a transparent cover to protect the light source and reflector, a battery, and a switch, all enclosed in a case.
A street light, light pole, lamp pole, lamppost, street lamp, light standard, or lamp standard is a raised source of light on the edge of a road or path. Similar lights may be found on a railway platform. When urban electric power distribution became ubiquitous in developed countries in the 20th century, lights for urban streets followed, or sometimes led.
The Tilley lamp is a kerosene pressure lamp.
There have been at least four lighthouses named Chennai Lighthouse or Madras Lighthouse, which face the Bay of Bengal on the east coast of the Indian Subcontinent in Chennai, India.
A solar tuki is a rechargeable solar lighting system that is being implemented in Nepal to replace kerosene lamps commonly used by villagers. It includes two lamps that have white LED lights powered by an individual solar panel. In 2004, Engineers Anil Chitrakar and Babu Raj Shrestha collaborated with their respective organizations, Environmental Camps for Conservation Awareness and Centre for Renewable Energy, to produce, distribute, and further the development of the solar tuki in Nepal. Their organizations sell the solar tuki systems, including solar panel, for $28 U.S. dollars, and the individual lamp is sold for $11.
Renewable energy in developing countries is an increasingly used alternative to fossil fuel energy, as these countries scale up their energy supplies and address energy poverty. Renewable energy technology was once seen as unaffordable for developing countries. However, since 2015, investment in non-hydro renewable energy has been higher in developing countries than in developed countries, and comprised 54% of global renewable energy investment in 2019. The International Energy Agency forecasts that renewable energy will provide the majority of energy supply growth through 2030 in Africa and Central and South America, and 42% of supply growth in China.
A solar lamp, also known as a solar light or solar lantern, is a lighting system composed of an LED lamp, solar panels, battery, charge controller and there may also be an inverter. The lamp operates on electricity from batteries, charged through the use of a solar photovoltaic panel.
Tjärven is the name of a small island and light station surrounded by deep water and located in the sea of Åland, north of the Söderarm archipelago of the coast of Sweden. The lighthouse functions as the entrance to the shipping route for the ports of Kapellskär, Norrtälje and Stockholm.
Nusantara Development Initiatives (NDI) is a nonprofit social enterprise that focuses on women, technology, and social impact. Its flagship program, Program Rumah Terang Nusantara (Mothers of Light Program), aims to end energy poverty and create growth in Indonesian villages by training rural women to become solar lamp entrepreneurs.
South Solitary Island Light is an active lighthouse on South Solitary Island, an island within the Solitary Islands Marine Park, about 15 kilometres (9.3 mi) northeast of Coffs Harbour, New South Wales, Australia. The lighthouse is located at the summit of the island. It is considered the most isolated lighthouse on the New South Wales coast. It was first in New South Wales to use kerosene over colza oil, and the last to do so before converting to electric power.
Cape Moreton Light, also listed as North Point Range Rear Light, is a heritage-listed active lighthouse located on Cape Moreton, a rocky headland located at the north eastern tip of Moreton Island, a large sand island on the eastern side of Moreton Bay, on the coast of South East Queensland, Australia. It marks the northern entrance to Moreton Bay and Brisbane and also serves as the rear light for the North Point Range. With its two distinctive red bands, it also serves as a daymark. It is the oldest lighthouse in Queensland, and the only one to be built by the New South Wales Government before the separation of Queensland, which took place in 1859. It is also the only lighthouse in Queensland to be built of stone.
The Appropriate Technology Collaborative is an American non-profit dedicated to designing everyday technologies for the global poor.
LuminAID is an emergency lighting company and the name of its key product, a solar-rechargeable light that packs flat and inflates to diffuse light like a lantern. LuminAID technology was invented in 2010 by Anna Stork and Andrea Sreshta. The company is based in Chicago.
Ann Kihengu is a Tanzanian entrepreneur, distributor, and winner of the 2010 Africa Laureate of the Cartier Women's Initiative Awards for her work to replace the use of kerosene lamps by distributing solar lamps and solar phone chargers in Tanzania via a network of young entrepreneurs. Kihengu is also a member of the World Entrepreneurship Forum Think Tank.
