Levi Yissar
Levi Yissar was an Israeli engineer and entrepreneur. He built the first prototype Israeli solar water heater. By 1967 around one in twenty households heated their water with the sun and 50,000 solar heaters had been sold. However, cheap oil from Iran and from oil fields captured in the Six-Day War made Israeli electricity cheaper and the demand for solar heaters to drop. Following the energy crisis in the 1970s, the Israeli Knesset The Knesset ( he, הַכְּנֶסֶת ; "gathering" or "assembly") is the unicameral legislature of Israel. As the supreme state body, the Knesset is sovereign and thus has complete control of the entirety of the Israeli government (with ... passed a law requiring the installation of solar water heaters in all new homes (except high towers with insufficient roof area).

Engineer
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professiona ...

Entrepreneur
Entrepreneurship is the creation or extraction of economic value. With this definition, entrepreneurship is viewed as change, generally entailing risk beyond what is normally encountered in starting a business, which may include other values than simply economic ones. An entrepreneur is an individual who creates and/or invests in one or more businesses, bearing most of the risks and enjoying most of the rewards.The process of setting up a business is known as entrepreneurship. The entrepreneur is commonly seen as an innovator, a source of new ideas, goods, services, and business/or procedures. More narrow definitions have described entrepreneurship as the process of designing, launching and running a new business, which is often similar to a small business, or as the "capacity and willingness to develop, organize and manage a business venture along with any of its risks to make a profit." The people who create these businesses are often referred to as entrepreneurs. While de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Water Heater
Solar water heating (SWH) is heating water by sunlight, using a solar thermal collector. A variety of configurations are available at varying cost to provide solutions in different climates and latitudes. SWHs are widely used for residential and some industrial applications (For example: in Israel). A sun-facing collector heats a working fluid that passes into a storage system for later use. SWH are active (pumped) and passive (convection-driven). They use water only, or both water and a working fluid. They are heated directly or via light-concentrating mirrors. They operate independently or as hybrids with electric or gas heaters. In large-scale installations, mirrors may concentrate sunlight into a smaller collector. As of 2017, global solar hot water (SHW) thermal capacity is 472 GW and the market is dominated by China, the United States and Turkey. Barbados, Austria, Cyprus, Israel and Greece are the leading countries by capacity per person. History Records of solar c ...

Household
A household consists of two or more persons who live in the same dwelling. It may be of a single family or another type of person group. The household is the basic unit of analysis in many social, microeconomic and government models, and is important to economics and inheritance. Household models include families, blended families, shared housing, group homes, boarding houses, houses of multiple occupancy (UK), and single room occupancy (US). In feudal societies, the royal household and medieval households of the wealthy included servants and other retainers. Government definitions For statistical purposes in the United Kingdom, a household is defined as "one person or a group of people who have the accommodation as their only or main residence and for a group, either share at least one meal a day or share the living accommodation, that is, a living room or sitting room". The introduction of legislation to control houses of multiple occupations in the UK Housing Act (200 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Six-Day War
The Six-Day War (, ; ar, النكسة, , or ) or June War, also known as the 1967 Arab–Israeli War or Third Arab–Israeli War, was fought between Israel and a coalition of Arab world, Arab states (primarily United Arab Republic, Egypt, Syria, and Jordan) from 5 to 10 June 1967. Escalated hostilities broke out amid poor relations between Israel and its Arab neighbours following the 1949 Armistice Agreements, which were signed at the end of the 1948 Arab–Israeli War, First Arab–Israeli War. Earlier, in 1956, regional tensions over the Straits of Tiran escalated in what became known as the Suez Crisis, when Israel invaded Egypt over the Israeli passage through the Suez Canal and Straits of Tiran, Egyptian closure of maritime passageways to Israeli shipping, ultimately resulting in the re-opening of the Straits of Tiran to Israel as well as the deployment of the United Nations Emergency Force (UNEF) along the Borders of Israel#Border with Egypt, Egypt–Israel border.

1973 Oil Crisis
The 1973 oil crisis or first oil crisis began in October 1973 when the members of the Organization of Arab Petroleum Exporting Countries (OAPEC), led by Saudi Arabia, proclaimed an oil embargo. The embargo was targeted at nations that had supported Israel during the Yom Kippur War. The initial nations targeted were Canada, Japan, the Netherlands, the United Kingdom and the United States, though the embargo also later extended to Portugal, Rhodesia and South Africa. By the end of the embargo in March 1974, the price of oil had risen nearly 300%, from US to nearly globally; US prices were significantly higher. The embargo caused an oil crisis, or "shock", with many short- and long-term effects on global politics and the global economy. It was later called the "first oil shock", followed by the 1979 oil crisis, termed the "second oil shock". Background Arab-Israeli conflict Ever since the recreation of the State of Israel in 1948 there has been Arab–Israeli conflict in the ...

Knesset
The Knesset ( he, הַכְּנֶסֶת ; "gathering" or "assembly") is the unicameral legislature of Israel. As the supreme state body, the Knesset is sovereign and thus has complete control of the entirety of the Israeli government (with the exception of checks and balances from the courts and local governments). The Knesset passes all laws, elects the president and prime minister (although the latter is ceremonially appointed by the President), approves the cabinet, and supervises the work of the government, among other things. In addition, the Knesset elects the state comptroller. It also has the power to waive the immunity of its members, remove the president and the state comptroller from office, dissolve the government in a constructive vote of no confidence, and to dissolve itself and call new elections. The prime minister may also dissolve the Knesset. However, until an election is completed, the Knesset maintains authority in its current composition.
