Solar Power In Israel
The use of solar energy began in Israel in the 1950s with the development by Levi Yissar of a solar water heater to address the energy shortages that plagued the new country.Petrotyranny by John C. Bacher, David Suzuki, published by Dundurn Press Ltd., 2000; Page 7/ref> By 1967 around 5% of water of households were solar heated and 50,000 solar heaters had been sold. With the 1973 oil crisis, 1970s oil crisis, Harry Zvi Tabor developed the prototype of the solar water heater now used in over 90% of Israeli homes.At the Zenith of Solar Energy Neal Sandler, ''Bloomberg BusinessWeek'', 26 March 2008. There are over 1.3 million solar water heaters installed as a result of mandatory solar water heating regul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photovoltaic Arrays At The Israeli National Solar Energy Center
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 Climate change mitigation, mitigate climate change because it emits much less Carbon dioxide in Earth's atmosphere, carbon dioxide than fossil fuels. Solar PV has specific advantages as an energy source: once installed, its operation does not generate any pollution or any Greenhouse gas, greenhouse gas emissions; it shows scalability in respect of power needs and silicon has lar ...

Feed-in Tariff
A feed-in tariff (FIT, FiT, standard offer contract,Couture, T., Cory, K., Kreycik, C., Williams, E., (2010)Policymaker's Guide to Feed-in Tariff Policy Design National Renewable Energy Laboratory, U.S. Dept. of Energy advanced renewable tariff, or renewable energy payments) is a policy mechanism designed to accelerate investment in renewable energy technologies by offering long-term contracts to renewable energy producers. This means promising renewable energy producers an above-market price and providing price certainty and long-term contracts that help finance renewable energy investments. Typically, FITs award different prices to different sources of renewable energy in order to encourage the development of one technology over another. For example, technologies such as wind power and solar PV are awarded a higher price per kWh than tidal power. FITs often include a "digression": a gradual decrease of the price or tariff in order to follow and encourage technological cost red ...

Arab–Israeli Conflict
The Arab–Israeli conflict is a geopolitical phenomenon involving military conflicts and a variety of disputes between Israel and many Arab world, Arab countries. It is largely rooted in the historically supportive stance of the Arab League towards the Palestinians in the context of the Israeli–Palestinian conflict, which, in turn, has been attributed to the simultaneous rise of Zionism and Arab nationalism towards the end of the 19th century, though the two movements did not directly clash until the 1920s. Since the late 20th century, however, direct hostilities of the Arab–Israeli conflict across the Middle East have mostly been attributed to a changing political atmosphere dominated primarily by the Iran–Israel proxy conflict. Part of the struggle between Israelis and Palestinians arose from the conflicting claims by the Zionist and Arab nationalist movements to the land that constituted British-ruled Mandatory Palestine. To the Zionist movement, Palestine was seen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Irradiance
Solar irradiance is the power per unit area (surface power density) received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Solar irradiance is measured in watts per square metre (W/m2) in SI units. Solar irradiance is often integrated over a given time period in order to report the radiant energy emitted into the surrounding environment (joule per square metre, J/m2) during that time period. This integrated solar irradiance is called solar irradiation, solar radiation, solar exposure, solar insolation, or insolation. Irradiance may be measured in space or at the Earth's surface after atmospheric absorption and scattering. Irradiance in space is a function of distance from the Sun, the solar cycle, and cross-cycle changes.Michael Boxwell, ''Solar Electricity Handbook: A Simple, Practical Guide to Solar Energy'' (2012), pp. 41–42. Irradiance on the Earth's surface additionally depends on the tilt of the measuri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
30th Parallel North
Following are circles of latitude between the 25th parallel north and the 30th parallel north: 26th parallel north The 26th parallel north is a circle of latitude that is 26 degrees north of the Earth's equatorial plane. It crosses Africa, Asia, the Indian Ocean, the Pacific Ocean, North America, and the Atlantic Ocean. A section of the border between Western Sahara and Mauritania is defined by the parallel. It is the most populous parallel on Earth, being home to between 247.2 million and 248.0 million people as of 2019. At this latitude the sun is visible for 13 hours, 46 minutes during the summer solstice and 10 hours, 31 minutes during the winter solstice. The sun is at 40.17 degrees in the sky during the winter solstice and 87.83 degrees in the sky during the summer solstice.

Geographic Latitude
In geography, latitude is a geographic coordinate that specifies the north-south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from −90° at the south pole to 90° at the north pole, with 0° at the Equator. Lines of constant latitude, or ''parallels'', run east-west as circles parallel to the equator. Latitude and longitude are used together as a coordinate pair to specify a location on the surface of the Earth. On its own, the term "latitude" normally refers to the ''geodetic latitude'' as defined below. Briefly, the geodetic latitude of a point is the angle formed between the vector perpendicular (or '' normal'') to the ellipsoidal surface from the point, and the plane of the equator. Background Two levels of abstraction are employed in the definitions of latitude and longitude. In the first step the physical surface is modeled by the geoid, a surface which approximates the mean sea level over the oc ...

Research And Development
Research and development (R&D or R+D), known in some countries as OKB, experiment and design, is the set of innovative activities undertaken by corporations or governments in developing new services or products. R&D constitutes the first stage of development of a potential new service or the production process. Although R&D activities may differ across businesses, the primary goal of an R&D department is to new product development, develop new products and services. R&D differs from the vast majority of corporate activities in that it is not intended to yield immediate profit, and generally carries greater risk and an uncertain return on investment. R&D is crucial for acquiring larger shares of the market through new products. ''R&D&I'' represents R&D with innovation. Background New product design and development is often a crucial factor in the survival of a company. In a global industrial landscape that is changing fast, firms must continually revise their design and range of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metric System
The metric system is a system of measurement that standardization, standardizes a set of base units and a nomenclature for describing relatively large and small quantities via decimal-based multiplicative unit prefixes. Though the rules governing the metric system have changed over time, the modern definition, the International System of Units (SI), defines the metric prefixes and seven base units: metre (m), kilogram (kg), second (s), ampere (A), kelvin (K), Mole (unit), mole (mol), and candela (cd). An SI derived unit is a named combination of base units such as hertz (cycles per second), Newton (unit), newton (kg⋅m/s2), and tesla (unit), tesla (1 kg⋅s−2⋅A−1) and in the case of Celsius a shifted scale from Kelvin. Certain units have been Non-SI units mentioned in the SI#Units officially accepted for use with the SI, officially accepted for use with the SI. Some of these are decimalised, like the litre and electronvolt, and are considered "metric". Others, like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Arabic Weights And Measures
The Ancient Arabic unit of measurements were a system of using units to associate with physical quantities. Arabic symbols are used to represent the values. The measurements were based on body measurements and common natural items. The length of forearm, shin and the standard size of a typical village were among the most accepted length units. About surface, usually Jerib or Djerib was the most usual unit which is mostly similar to acre or hectare. Another unit known as Sa was mostly used to measure volume which is approximately equal to 3 liters. Although having similar names, the size of units may differ depending on region. Length See also * Uqiyyah, the Arabic ounce or half-pound, depending on region. * Qafiz, an Arabic unit for measuring volumes. * Sāʿ, an ancient unit of volume, equal to 2 to 4 liters, depending on region. * The Arabic mile (''al-mīl''), a unit of length employed by Arab geographers and scientists.

Imperial Units
The imperial system of units, imperial system or imperial units (also known as British Imperial or Exchequer Standards of 1826) is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments. The imperial system developed from earlier English units as did the Comparison of the imperial and US customary measurement systems, related but differing system of United States customary units, customary units of the United States. The imperial units replaced the Winchester measure, Winchester Standards, which were in effect from 1588 to 1825. The system came into official use across the British Empire in 1826. By the late 20th century, most nations of the former empire had metrication, officially adopted the metric system as their main system of measurement, but imperial units are still used alongside metric units in the United Kingdom and in some other parts of the former empi ...
