Edgard Nazare
Edgard Nazare (1914–1998) was a French aeronautical engineer and inventor. He specialized in fluid mechanics, co-founder of the Aeronautical Research Office of Algiers, which became ONERA after the Second World War. Having worked for a long time in the Sahara, he had the opportunity to observe many whirlwinds of sand (dust devil). In 1956 he filed his first patent in Algiers on the artificial cyclone generator, this patent was re-filed later in Paris. Patents * Artificial cyclone generator – French patent 1439849 * Tower construction for solar aero-thermal and aero-cooling stations – has metal framework mounted on central telescopic mast – French patent 8205544 See also * Solar updraft tower The solar updraft tower (SUT) is a design concept for a renewable energy, renewable-energy power plant for generating electricity from low temperature solar heat.

ONERA
The Office National d'Études et de Recherches Aérospatiales ( English: National office for aerospace studies and research) or ONERA, dubbed ''The French Aerospace Lab'' in English, is the French national aerospace research center. Originally founded as the ''Office National d’Études et de Recherches Aéronautiques'' (National Office for Aeronautical Studies and Research) in 1946, it was relabeled in 1963. It is France's leading research center in aerospace and defense. It covers all disciplines and technologies in the field. Numerous high-profile French and European aerospace programs have passed through the ONERA since its creation including the Ariane family of launch vehicles, the Concorde supersonic airliner, the Dassault Mirage family of fighter aircraft and the Rafale, the Dassault Falcon family of business jets, Aérospatiale and later Airbus projects, missiles, engines, radars and many more. Under the supervision of the Ministry of the Armed Forces, it is a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Updraft Tower
The solar updraft tower (SUT) is a design concept for a renewable energy, renewable-energy power plant for generating electricity from low temperature solar heat. Sunshine heats the air beneath a very wide greenhouse-like roofed collector structure surrounding the central base of a very tall chimney tower. The resulting convection causes a hot air updraft in the tower by the chimney effect. This airflow drives wind turbines, placed in the chimney updraft or around the chimney base, to produce electricity. As of mid 2018, although several prototype models have been built, no full-scale practical units are in operation. Scaled-up versions of demonstration models are planned to generate significant power. They may also allow development of other applications, such as to agriculture or horticulture, to water extraction or distillation, or to remediate urban air pollution.. Commercial investment may have been discouraged by the high initial cost of building a very large novel structu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Conversion
Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. In physics, energy is a quantity that provides the capacity to perform Work (physics), work (e.g. lifting an object) or provides heat. In addition to being converted, according to the law of conservation of energy, energy is transferable to a different location or object or living being, but it cannot be created or destroyed. Limitations in the conversion of thermal energy Conversions to thermal energy from other forms of energy may occur with 100% efficiency. Conversion among non-thermal forms of energy may occur with fairly high efficiency, though there is always some energy dissipated thermally due to friction and similar processes. Sometimes the efficiency is close to 100%, such as when potential energy is converted to kinetic energy as an object falls in a vacuum. This also applies to the opposite case; for example, an object in an Elliptic orbit, elliptical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Solar Power
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine. Photovoltaics (PV) were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar panels has fallen, grid-connected solar PV systems' capacity and production has doubled about every three years. Three-quarters of new generation capacity is solar, with both millions of rooftop installatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sustainable Energy
Energy system, Energy is sustainability, sustainable if it "meets the needs of the present without compromising the ability of future generations to meet their own needs." Definitions of sustainable energy usually look at its effects on the environment, the economy, and society. These impacts range from greenhouse gas emissions and air pollution to energy poverty and toxic waste. Renewable energy sources such as wind power, wind, Hydroelectricity, hydro, solar energy, solar, and geothermal energy can cause environmental damage but are generally far more sustainable than fossil fuel sources. The role of Non-renewable resource, non-renewable energy sources in sustainable energy is controversial. Nuclear power does Low-carbon power, not produce carbon pollution or air pollution, but has drawbacks that include radioactive waste, the risk of nuclear proliferation, and the Nuclear and radiation accidents and incidents, risk of accidents. Switching from coal to natural gas has enviro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1914 Births
This year saw the beginning of what became known as the First World War, after Archduke Franz Ferdinand of Austria, heir to the Austrian throne was Assassination of Archduke Franz Ferdinand, assassinated by Serbian nationalist Gavrilo Princip. It also saw the first airline to provide scheduled regular commercial passenger services with heavier-than-air aircraft, with the St. Petersburg–Tampa Airboat Line. Events January * January 1 – The St. Petersburg–Tampa Airboat Line in the United States starts services between St. Petersburg, Florida, St. Petersburg and Tampa, Florida, becoming the first airline to provide scheduled regular commercial passenger services with heavier-than-air aircraft, with Tony Jannus (the first federally-licensed pilot) conveying passengers in a Benoist XIV flying boat. Abram C. Pheil, mayor of St. Petersburg, is the first airline passenger, and over 3,000 people witness the first departure. * January 11 **The Sakurajima volcano in Japan ...
