Solar Powered Radio
A solar powered radio is a portable radio receiver powered by photovoltaic panels. It is primarily used in remote areas where access to power sources is limited. History The solar powered radio first came into existence in the 1950s. An experimental model, developed by General Electric, weighed just 10 ounces and was capable of working without light and recharging. It contained seven solar cells, four transistors and a small battery. In 1954, Western Electric began to sell commercial licenses solar powered radio, including other photovoltaic technologies. In 1957 the Sarkis Acopian, Acopian Technical Co. of Pohatcong Township, New Jersey, was reported as manufacturing the first solar radios for commercial sale to the general public. Advantages Solar powered radios eliminate the need to replace batteries, which makes operating them cost much less. Since they don't require plugs, they can be used in areas where there is no electrical grid or generators. As a result, people in ...

Radio Receiver
In radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves (electromagnetic waves of radio frequency) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information. The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation. Radio receivers are essential components of all systems that use radio. The information produced by the receiver may be in the form of sound, video (television), or digital data. A radio receiver may be a separate piece of electronic equipment, or an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photovoltaic Panel
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors. A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating. The mount may be fixed or use a solar tracker to follow the sun across the sky. Photovoltaic technology helps to mitigate climate change because it emits much less carbon dioxide than fossil fuels. Solar PV has specific advantages as an energy source: once installed, its operation generates no pollution and no greenhouse gas emissions, it shows scalability in respect of power needs and silicon has large availability in the Earth's crust, although other materials required in PV system manuf ...

General Electric
General Electric Company (GE) is an American multinational conglomerate founded in 1892, and incorporated in New York state and headquartered in Boston. The company operated in sectors including healthcare, aviation, power, renewable energy, digital industry, additive manufacturing and venture capital and finance, but has since divested from several areas, now primarily consisting of the first four segments. In 2020, GE ranked among the Fortune 500 as the 33rd largest firm in the United States by gross revenue. In 2011, GE ranked among the Fortune 20 as the 14th most profitable company, but later very severely underperformed the market (by about 75%) as its profitability collapsed. Two employees of GE – Irving Langmuir (1932) and Ivar Giaever (1973) – have been awarded the Nobel Prize. On November 9, 2021, the company announced it would divide itself into three investment-grade public companies. On July 18, 2022, GE unveiled the brand names of the companies it will ...

The #International avoirdupois ounce, avoirdupois ounce (exactly ) is Pound (mass)#Avoirdupois pound, avoirdupois pound; this is the United States customary units, United States customary and British imperial unit, imperial ounce. It is primarily used in the United States to measure packaged foods and food portions, postal items, areal density of fabric and paper, boxing gloves, and so on, but it is sometimes also used elsewhere in the Anglosphere. Although the avoirdupois ounce is the mass measure used for most purposes, the 'troy ounce' of exactly is used instead for the mass of precious metals such as gold, silver, platinum, palladium, rhodium, etc. The term 'ounce' is also used in other contexts: * The #Ounce-force, ounce-force is a measure of force (see below). * The fluid ounce is a m ...

Sarkis Acopian
Sarkis Acopian ( hy, Սարգիս Յակոբեան; December 8, 1926 – January 18, 2007) was an inventor, industrialist, environmentalist, and humanitarian. Early life Acopian was born in the Iranian city of Tabriz in a family of Armenian refugees from the Ottoman Empire. He came to the United States as an immigrant from Iran in 1945. He studied mechanical engineering at Lafayette College in Easton, Pennsylvania. He left Lafayette to serve in the United States Army. After he received an honorable discharge, he graduated from Lafayette with a B.S. in mechanical engineering. Career After graduation, Acopian was employed by Weller Electric Corp., where he designed a power sander and a soldering gun that later became two of their main products. Acopian's own success as an engineer inspired him to start his own business. Taking out a small loan, he founded his own company, Acopian Technical Company, in 1957 to realize his own " American dream". There he designed and manufactured ...

Batteryless Radio
A batteryless radio is a radio receiver which does not require the use of a battery to provide it with electrical power. Originally this referred to units which could be used directly by AC mains supply (mains radio); it can also refer to units which do not require a power source at all, except for the power that they receive from radio waves. History The line-operated vacuum tube receiver was invented in 1925 by Edward S. Rogers, Sr. The unit operated with 5 Rogers AC vacuum tubes and the Rogers Battery-Eliminator Power Unit (power supply). This unit was later marketed for $120 as "Type 120". He established the Toronto station CFRB (an abbreviation of ''Canada's First Rogers Batteryless'') to promote sales of the product. Batteryless radios were not introduced into the United States until May 1926 and then into Europe in 1927. Crystal radio receivers are a very simple kind of batteryless radio receiver. They do not need a battery or power source, except for the power that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Human power is work or energy In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of hea ... that is produced from the human body. It can also refer to the power (physics), power (rate of work per time) of a human. Power comes primarily from List of skeletal muscles of the human body, muscles, but Thermoregulation, body heat is also used to do work like warming Shelter (building), shelters, food, or other humans.
