Alfredo Moser
Alfredo Moser ( 1951/1952 in Itajaí) is a Brazilian mechanic, and the inventor of the solar bottle bulb, known also as the ‘Moser Lamp’, or the PET bottle lamp. His invention led to the creation of the open-source organization Liter of Light, which offers sustainable lighting to families without electricity access in numerous countries worldwide. Early life Moser was born in rural Santa Catarina in 1951 and began his life working as a farmhand. He later moved to Brasília, where he worked as an auto mechanic. In 1978, he married his wife Carmelinda and then moved to Minas Gerais, settling with his family in Uberaba by 1980. The Moser lamp Conception According to Moser, his inspiration for the invention emerged as a DIY solution in response to the blackouts during the 2001–2002 Brazilian energy crisis. However, the idea dates back to the late 1970s when he was working as a car mechanic for a telecommunications company in Brasília. On one occasion, imagining a sc ...

Itajaí
Itajaí () is a municipality in the state of Santa Catarina, Brazil. It is located on the northern central coast of Santa Catarina and is part of the Vale do Itajaí Mesoregion, on the right bank of the Itajaí-Açu river mouth. It lies at the mouth of the Itajaí River, at 20 feet (6 metres) above sea level. The city has the 2nd largest gross domestic product and the highest per capita income in the State of Santa Catarina. History The city was founded on June 15, 1860, but the colonization of Itajaí had started in 1658 when the Paulista João Dias D'Arzão arrived in the region. In 1750, Portuguese colonists coming from Madeira and the Azores made this region their home. By 1823 it became a prominent region for Portuguese settlers and, at the end of the 19th century, received a great number of German immigrants. Itajaí and most of Santa Catarina State area is prone to torrential storms specially during the Spring season. Floods are frequent and even tornadoes can form. ...

Electricity Sector In Brazil
Brazil has the largest electricity sector in Latin America. In 2024, Brazil added a substantial 10.9 GW of new power generation capacity, with a total installed capacity of 209 GW, of which nearly 85% was renewable. The installed capacity grew from 11,000 MW in 1970 with an average yearly growth of 5.8% per year. Brazil has the largest capacity for water storage in the world, being dependent on hydroelectricity generation capacity, which meets over 60% of its electricity demand. The national grid runs at 60 Hz and is powered 83% from renewable sources. This dependence on hydropower makes Brazil vulnerable to power supply shortages in drought years, as was demonstrated by the 2001–2002 energy crisis.World Bank 2007 In 2023, the output of Brazil's electricity system, serving over 88 million consumers, exceeded that of all other South American nations combined. Anticipated investments surpassing $100 billion by 2029 aim to expand utility-scale and distributed generation, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Incandescent Light Bulb
An incandescent light bulb, also known as an incandescent lamp or incandescent light globe, is an electric light that produces illumination by Joule heating a #Filament, filament until it incandescence, glows. The filament is enclosed in a glass bulb that is either vacuum, evacuated or filled with inert gas to protect the filament from oxidation. Electric current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections. Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external Regulator (automatic control), regulating equipment, have low manufacturing costs, and work equally well on either alternating current or direct current. As a result, the incandescent bulb became widely used in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, an ...

Refraction
In physics, refraction is the redirection of a wave as it passes from one transmission medium, medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and Wind wave, water waves also experience refraction. How much a wave is refracted is determined by the change in wave speed and the initial direction of wave propagation relative to the direction of change in speed. Optical Prism (optics), prisms and Lens (optics), lenses use refraction to redirect light, as does the human eye. The refractive index of materials varies with the wavelength of light,R. Paschotta, article ochromatic dispersion in th, accessed on 2014-09-08 and thus the angle of the refraction also varies correspondingly. This is called dispersion (optics), dispersion and causes prism (optics), prisms and rainbows to divide white light into its constituent spectral ...

Water Chlorination
Water chlorination is the process of adding chlorine or chlorine compounds such as sodium hypochlorite to water. This method is used to kill bacteria, viruses and other microbes in water. In particular, chlorination is used to prevent the spread of waterborne diseases such as cholera, dysentery, and typhoid. History In a paper published in 1894, it was formally proposed to add chlorine to water to render it "germ-free". Two other authorities endorsed this proposal and published it in many other papers in 1895. Early attempts at implementing water chlorination at a water treatment plant were made in 1893 in Hamburg, Germany. In 1897 the town of Maidstone, England was the first to have its entire water supply treated with chlorine. Permanent water chlorination began in 1905, when a faulty slow sand filter and a contaminated water supply caused a serious typhoid fever epidemic in Lincoln, England. Alexander Cruickshank Houston used chlorination of the water to stop the epidem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroponics
Hydroponics is a type of horticulture and a subset of #Passive sub-irrigation, hydroculture which involves growing plants, usually crops or medicinal plants, without soil, by using water-based mineral Plant nutrition, nutrient Solution (chemistry), solutions in an artificial environment. Terrestrial plant, Terrestrial or aquatic plants may grow freely with their roots exposed to the nutritious liquid or the roots may be mechanically supported by an inert medium such as perlite, gravel, or Hydroponics#Substrates (growing support materials), other substrates. Despite inert media, roots can cause changes of the rhizosphere pH and root exudates can affect rhizosphere biology and physiological balance of the nutrient solution when secondary metabolites are produced in plants. Genetically modified plant, Transgenic plants grown hydroponically allow the release of Pharming (genetics)#In plants, pharmaceutical proteins as part of the root exudate into the hydroponic medium.

Solar Panel
A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. These electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in battery (electricity), batteries. Solar panels are also known as solar cell panels, solar electric panels, or PV modules. Solar panels are usually arranged in groups called arrays or systems. A photovoltaic system consists of one or more solar panels, an solar inverter, inverter that converts DC electricity to alternating current (AC) electricity, and sometimes other components such as charge controller, controllers, Measuring instrument, meters, and solar tracker, trackers. Most panels are in solar farms or Rooftop solar power, rooftop solar panels which grid-connected photovoltaic system, supply the electricity grid. Some advantages of solar panels are ...

Polyester Resin
Polyester resins are synthetic resins formed by the reaction of dibasic organic acids and polyhydric alcohols. Maleic anhydride is a commonly used raw material with diacid functionality in unsaturated polyester resins. Unsaturated polyester resins are used in sheet moulding compound, bulk moulding compound and the toner of laser printers. Wall panels fabricated from polyester resins reinforced with fiberglassso-called fiberglass reinforced plastic (FRP)are typically used in restaurants, kitchens, restrooms and other areas that require washable low-maintenance walls. They are also used extensively in cured-in-place pipe applications. Departments of Transportation in the USA also specify them for use as overlays on roads and bridges. In this application they are known AS Polyester Concrete Overlays (PCO). These are usually based on isophthalic acid and cut with styrene at high levelsusually up to 50%.

Bleach
Bleach is the generic name for any chemical product that is used industrially or domestically to remove color from (i.e. to whiten) fabric or fiber (in a process called bleaching) or to disinfect after cleaning. It often refers specifically to a dilute solution of sodium hypochlorite, also called "liquid bleach". Many bleaches have broad-spectrum bactericidal properties, making them useful for disinfecting and sterilizing. They are used in swimming pool sanitation to control bacteria, viruses, and algae and in many places where sterile conditions are required. They are also used in many industrial processes, notably in the bleaching of wood pulp. Bleaches also have other minor uses, like removing mildew, killing weeds, and increasing the longevity of cut flowers. Bleaches work by reacting with many colored organic compounds, such as natural pigments, and turning them into colorless ones. While most bleaches are oxidizing agents (chemicals that can remove electrons from ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
