Palmer Putnam
Palmer Cosslett Putnam (1900–1984) was an American consulting engineer and wind-power pioneer, the son of George Haven Putnam and Emily (Smith) Putnam (1865–1944). Putnam graduated from MIT in 1924 as a geologist after serving in the RAF during World War I. He is known as the designer of the Smith–Putnam wind turbine installed in 1941 in Vermont, the first megawatt-scale wind turbine project. Putnam wrote on the subject of wind power including "Power from the Wind" published in 1948, with an introduction by Vannevar Bush, describing the Smith–Putnam project. His book "Energy in the Future", 1953, was reviewed in the journal " Science". Putnam served as the president of G. P. Putnam's Sons G. P.

Smith–Putnam Wind Turbine
The Smith–Putnam wind turbine was the world's first megawatt-size wind turbine. In 1941 it was connected to the local electrical distribution system on Grandpa's Knob in Castleton, Vermont, US. It was designed by Palmer Cosslett Putnam and manufactured by the S. Morgan Smith Company. The 1.25 MW turbine operated for 1100 hours before a blade failed at a known weak point, which had not been reinforced due to wartime material shortages. It would be the largest wind turbine ever built until 1979. Description The turbine had two blades, in diameter, on the down-wind side of a -foot steel lattice tower. Each blade was approximately wide and long, and weighed eight tons. The blades were built on steel spars and covered with a stainless steel skin. The blade spars were hinged at their root attachment to the hub, allowing them to assume a slight cone shape. The generator was a 1250 kva 600 RPM synchronous generator made by General Electric, producing 2,400 V at 60 cycle ...

Consulting 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 professio ...

Wind Power
Wind power or wind energy is mostly the use of wind turbines to generate electricity. Wind power is a popular, sustainable, renewable energy source that has a much smaller impact on the environment than burning fossil fuels. Historically, wind power has been used in sails, windmills and windpumps but today it is mostly used to generate electricity. Wind farms consist of many individual wind turbines, which are connected to the electric power transmission network. New onshore (on-land) wind farms are cheaper than new coal or gas plants, but expansion of wind power is being hindered by fossil fuel subsidies. Onshore wind farms have a greater visual impact on the landscape than some other power stations. Small onshore wind farms can feed some energy into the grid or provide power to isolated off-grid locations. Offshore wind farms deliver more energy per installed capacity with less fluctuations and have less visual impact. Although there is less offshore wind power ...

George Haven Putnam
George Haven Putnam A.M., Litt.D. (April 2, 1844 – February 27, 1930) was an American publisher, soldier, and writer. He was the president of G. P. Putnam's Sons for its first 52 years, from 1872. Biography The eldest son of publisher George Palmer Putnam and Victorine Haven Putnam, he was born in London, UK where his father had been living since 1841 while establishing a branch office for his New York City publishing company, Wiley & Putnam. In 1848 the family returned to the United States, settling at Stapleton, New York, on Staten Island. Haven's early instruction was at home by his mother and nurse. He was prepared for college, first, by the Rev. Dr. Stephen H. Tyng, who had a class of boys at St. George's Church, of which Dr. Tyng was rector, and his son, Stephen H. Tyng, Jr., instructor of a company of cadets. Haven next entered Starr's Military Academy, Yonkers, New York. In 1857 he attended Prof. John MacMullen's school in upper New York and the Columbia Grammar School ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Geologist
A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, earth science, or geophysics, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field research (field work) is an important component of geology, although many subdisciplines incorporate laboratory and digitalized work. Geologists can be classified in a larger group of scientists, called geoscientists. Geologists work in the energy and mining sectors searching for natural resources such as petroleum, natural gas, precious and base metals. They are also in the forefront of preventing and mitigating damage from natural hazards and disasters such as earthquakes, volcanoes, tsunamis and landslides. Their studies are used to warn the general public of the occurrence of these events. Geologists are also important contributors to ...

Wind Turbine
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. Hundreds of thousands of large turbines, in installations known as wind farms, now generate over 650 gigawatts of power, with 60 GW added each year. Wind turbines are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels. One study claimed that, wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and the most favorable social impacts" compared to photovoltaic, hydro, geothermal, coal and gas energy sources. Smaller wind turbines are used for applications such as battery charging for auxiliary power for boats or caravans, and to power traffic warning signs. Larger turbines can contribute to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Wind turbines are manufactured in a wide ran ...

Vannevar Bush
Vannevar Bush ( ; March 11, 1890 – June 28, 1974) was an American engineer, inventor and science administrator, who during World War II headed the U.S. Office of Scientific Research and Development (OSRD), through which almost all wartime military R&D was carried out, including important developments in radar and the initiation and early administration of the Manhattan Project. He emphasized the importance of scientific research to national security and economic well-being, and was chiefly responsible for the movement that led to the creation of the National Science Foundation. Bush joined the Department of Electrical Engineering at Massachusetts Institute of Technology (MIT) in 1919, and founded the company that became the Raytheon Company in 1922. Bush became vice president of MIT and dean of the MIT School of Engineering in 1932, and president of the Carnegie Institution of Washington in 1938. During his career, Bush patented a string of his own inventions. He is kno ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

DUKW
The DUKW (colloquially known as Duck) is a six-wheel-drive amphibious modification of the -ton CCKW trucks used by the U.S. military during World War II and the Korean War. Designed by a partnership under military auspices of Sparkman & Stephens and General Motors Corporation (GMC), the DUKW was used for the transportation of goods and troops over land and water. Excelling at approaching and crossing beaches in amphibious warfare attacks, it was intended only to last long enough to meet the demands of combat. Surviving DUKWs have since found popularity as tourist craft in marine environments. Etymology The name DUKW comes from General Motors Corporation model nomenclature: * D, 1942 production series * U, Utility * K, front wheel drive * W, tandem rear axles, both driven Decades later, the designation was explained erroneously by writers such as Donald Clarke, who wrote in 1978 that it was an initialism for "Duplex Universal Karrier, Wheeled".

Smithsonian (magazine)
''Smithsonian'' is the official journal published by the Smithsonian Institution in Washington, D.C. The first issue was published in 1970. History The history of ''Smithsonian'' began when Edward K. Thompson, the retired editor of ''Life'' magazine, was asked by the then-Secretary of the Smithsonian, S. Dillon Ripley, to produce a magazine "about things in which the Smithsonian nstitutionis interested, might be interested or ought to be interested." Thompson would later recall that his philosophy for the new magazine was that it "would stir curiosity in already receptive minds. It would deal with history as it is relevant to the present. It would present art, since true art is never dated, in the richest possible reproduction. It would peer into the future via coverage of social progress and of science and technology. Technical matters would be digested and made intelligible by skilled writers who would stimulate readers to reach upward while not turning them off with jargon ...

Smithsonian Institution
The Smithsonian Institution ( ), or simply the Smithsonian, is a group of museums and education and research centers, the largest such complex in the world, created by the U.S. government "for the increase and diffusion of knowledge". Founded on August 10, 1846, it operates as a trust instrumentality and is not formally a part of any of the three branches of the federal government. The institution is named after its founding donor, British scientist James Smithson. It was originally organized as the United States National Museum, but that name ceased to exist administratively in 1967. Called "the nation's attic" for its eclectic holdings of 154 million items, the institution's 19 museums, 21 libraries, nine research centers, and zoo include historical and architectural landmarks, mostly located in the District of Columbia. Additional facilities are located in Maryland, New York, and Virginia. More than 200 institutions and museums in 45 states,States without Smithsonian ...
