Query: Who developed the first wind turbine to create electricity?
The first windmill used for the production of electric power was built in Scotland in July 1887 by Prof James Blyth of Anderson's College, Glasgow (the precursor of Strathclyde University). Blyth's high, cloth-sailed wind turbine was installed in the garden of his holiday cottage at Marykirk in Kincardineshire and was used to charge accumulators developed by the Frenchman Camille Alphonse Faure, to power the lighting in the cottage, thus making it the first house in the world to have its electric power supplied by wind power. Blyth offered the surplus electric power to the people of Marykirk for lighting the main street, however, they turned down the offer as they thought electric power was "the work of the devil." Although he later built a wind turbine to supply emergency power to the local Lunatic Asylum, Infirmary and Dispensary of Montrose, the invention never really caught on as the technology was not considered to be economically viable.
In 1654, Otto von Guericke invented the first vacuum pump and conducted his famous Magdeburg hemispheres experiment, showing that teams of horses could not separate two hemispheres from which the air had been partially evacuated. Robert Boyle improved Guericke's design and with the help of Robert Hooke further developed vacuum pump technology. Thereafter, research into the partial vacuum lapsed until 1850 when August Toepler invented the Toepler Pump and Heinrich Geissler invented the mercury displacement pump in 1855, achieving a partial vacuum of about 10 Pa (0.1 Torr). A number of electrical properties become observable at this vacuum level, which renewed interest in further research.
On July 31, 1790 inventor Samuel Hopkins of Pittsford, Vermont became the first person to be issued a patent in the United States. His patented invention was an improvement in the "making of Pot Ash by a new apparatus & process." These earliest patent law required that a working model of each invention be produced in miniature.

In 1902, the first modern electrical air conditioning unit was invented by Willis Carrier in Buffalo, New York. After graduating from Cornell University, Carrier found a job at the Buffalo Forge Company. There, he began experimenting with air conditioning as a way to solve an application problem for the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, New York. The first air conditioner, designed and built in Buffalo by Carrier, began working on 17 July 1902.
The Cooke and Wheatstone telegraph was an early electrical telegraph system dating from the 1830s invented by English inventor William Fothergill Cooke and English scientist Charles Wheatstone. It was the first telegraph system to be put into commercial service. The receiver consisted of a number of needles which could be moved by electromagnetic coils to point to letters on a board. This feature was liked by early users who were unwilling to learn codes, and employers who did not want to invest in staff training.
Engineers such as John Smeaton, Peter Ewart, , Gustave-Adolphe Hirn and Marc Seguin recognized that conservation of momentum alone was not adequate for practical calculation and made use of Leibniz's principle. The principle was also championed by some chemists such as William Hyde Wollaston. Academics such as John Playfair were quick to point out that kinetic energy is clearly not conserved. This is obvious to a modern analysis based on the second law of thermodynamics, but in the 18th and 19th centuries the fate of the lost energy was still unknown.

The carbon microphone was independently developed around 1878 by David Edward Hughes in England and Emile Berliner and Thomas Edison in the US. Although Edison was awarded the first patent in mid-1877, Hughes had demonstrated his working device in front of many witnesses some years earlier, and most historians credit him with its invention.
The prediction that light represented a transmission of energy in wave form through a "luminiferous ether", and the seeming confirmation of that prediction with Helmholtz student Heinrich Hertz's 1888 detection of electromagnetic radiation, was a major triumph for physical theory and raised the possibility that even more fundamental theories based on the field could soon be developed. Experimental confirmation of Maxwell's theory was provided by Hertz, who generated and detected electric waves in 1886 and verified their properties, at the same time foreshadowing their application in radio, television, and other devices. In 1887, Heinrich Hertz discovered the photoelectric effect. Research on the electromagnetic waves began soon after, with many scientists and inventors conducting experiments on their properties. In the mid to late 1890s Guglielmo Marconi developed a radio wave based wireless telegraphy system (see invention of radio).
Sir Hiram Stevens Maxim (5 February 1840 – 24 November 1916) was an American-born British inventor, best known as the creator of the Maxim gun, the first portable fully automatic machine gun. Maxim held patents on numerous mechanical devices such as a mousetrap, hair-curling irons, and steam pumps, and laid claim to inventing the lightbulb. He also experimented with powered flight but his large aircraft designs were never successful, however, his "Captive Flying Machine" amusement ride, designed as a means by which to fund his research while generating public interest in flight, was highly successful.
Morey's first patent, in 1793, was for a steam-powered spit, but he had grander plans. Morey realized that steam could be a power source in the 1780s, and he probably appreciated a steamboat’s potential from work on his father’s ferry and the locks he designed along the Connecticut river. In the early 1790s he fitted a paddle wheel and steam engine to a small boat and powered it up and down the Connecticut River. Legend has it, this was done on a Sunday morning, when the town was at church, to avoid ridicule if he failed.
The most important aspect of this craft was the paddle wheel. It was an old idea – supposedly dating to antiquities – and previously tried with a steam engine. Jonathan Hulls of England used a rear-mounted paddle wheel in 1737 but an inefficient method of turning the steam engine’s reciprocating motion into the circular motion hobbled it. In 1789, Nathan Reed of Massachusetts experimented with a paddle wheel, and considered patenting it, but eventually patented a different method instead. The American John Fitch experimented with side-mounted paddle wheels, but in 1791 used and patented oars instead. Morey's may have been the first successful use of a steam power paddle wheel, which was the best method of propulsion until the propeller, invented by Fitch, was perfected.
William Grove produced the first fuel cell in 1839. He based his experiment on the fact that sending an electric current through water splits the water into its component parts of hydrogen and oxygen. So, Grove tried reversing the reaction—combining hydrogen and oxygen to produce electricity and water. Eventually the term "fuel cell" was coined in 1889 by Ludwig Mond and Charles Langer, who attempted to build the first practical device using air and industrial coal gas. He also introduced a powerful battery at the annual meeting of the British Association for the Advancement of Science in 1839. Grove's first cell consisted of zinc in diluted sulfuric acid and platinum in concentrated nitric acid, separated by a porous pot. The cell was able to generate about 12 amperes of current at about 1.8 volts. This cell had nearly double the voltage of the first Daniell cell. Grove's nitric acid cell was the favourite battery of the early American telegraph (1840–1860), because it offered strong current output.
In 1857, Édouard-Léon Scott de Martinville invented the phonautograph, the first device that could record sound waves as they passed through the air. It was intended only for visual study of the recording and could not play back the sound. The recording medium was a sheet of soot-coated paper wrapped around a rotating cylinder carried on a threaded rod. A stylus, attached to a diaphragm through a series of levers, traced a line through the soot, creating a graphic record of the motions of the diaphragm as it was minutely propelled back and forth by the audio-frequency variations in air pressure.
Modern thermostat control was developed in the 1830s by Andrew Ure (1778–1857), a Scottish chemist, who invented the bi-metallic thermostat. The textile mills of the time needed a constant and steady temperature to operate optimally, so to achieve this Ure designed the bimetallic thermostat, which would bend as one of the metals expanded in response to the increased temperature and cut off the energy supply.
The first microphone that enabled proper voice telephony was the (loose-contact) carbon microphone (then called transmitter). This was independently developed around 1878 by David Edward Hughes in England and Emile Berliner and Thomas Edison in the US. Although Edison was awarded the first patent in mid-1877, Hughes had demonstrated his working device in front of many witnesses some years earlier, and most historians credit him with its invention.
Renewable Energy Business.  Influenced by architect, inventor and philosopher, "Buckminster Fuller", who believed in the importance of "renewable energy", Osborne began to focus on the renewable energy business in the late 1970s by building "passive solar homes" and selling energy-saving wood stoves. In 1981 he developed the first "wind energy" project (consisting of five 25-kilowatt "wind turbines") that sold energy to an "electric utility" in Texas. in 1983, he signed on as the first distributor in Texas for "Solarex", a now-defunct maker of "solar cells" used then as power sources for such things as ranch gates, railroad signals and other places where stringing power lines was difficult or expensive. In the 1990s he ran the Texas operations for "Zond Energy", which is now part of "GE Wind Energy", the largest U.S. "wind turbine" maker. Throughout the 80's and 90s, Osborne documented and leased the wind resource for Texas wind fields. Many of his exploits are documented in the book, "The Great Texas Wind Rush".
The first person to use resonant circuits in a radio application was Nikola Tesla, who invented the resonant transformer in 1891. At a March 1893 St. Louis lecture he had demonstrated a wireless system that, although it was intended for wireless power transmission, had many of the elements of later radio communication systems. A grounded capacitance-loaded spark-excited resonant transformer (his "Tesla coil") attached to an elevated wire monopole antenna transmitted radio waves, which were received across the room by a similar wire antenna attached to a receiver consisting of a second grounded resonant transformer tuned to the transmitter's frequency, which lighted a Geissler tube. This system, patented by Tesla 2 September 1897, 4 months after Lodge's "syntonic" patent, was in effect an inductively coupled radio transmitter and receiver, the first use of the "four circuit" system claimed by Marconi in his 1900 patent "(below)". However, Tesla was mainly interested in wireless power and never developed a practical radio "communication" system.
The inventor Ding Huan (fl. 180 AD) of the Han dynasty invented a rotary fan for air conditioning, with seven wheels 3 m (10 ft) in diameter and manually powered. In 747, Emperor Xuanzong had a "Cool Hall" built in the imperial palace, which the "Tang Yulin" (唐語林) describes as having water-powered fan wheels for air conditioning as well as rising jet streams of water from fountains. During the subsequent Song dynasty, written sources mentioned the air conditioning rotary fan as even more widely used.
Around 8000 engines were produced to power the tanks, making this engine the UK's first mass-produced internal combustion engine. Many more of these engines found applications powering generators in workshops, hospitals and camps. The success of this venture yielded £30,000 in royalties and led to Harry Ricardo being able to buy the land and set up the company on its present site in 1919.
Soon after leaving the Edison company, Tesla was working on patenting an arc lighting system, possibly the same one he had developed at Edison. In March 1885, he met with patent attorney Lemuel W. Serrell, the same attorney used by Edison, to obtain help with submitting the patents. Serrell introduced Tesla to two businessmen, Robert Lane and Benjamin Vail, who agreed to finance an arc lighting manufacturing and utility company in Tesla's name, the Tesla Electric Light & Manufacturing. Tesla worked for the rest of the year obtaining the patents that included an improved DC generator, the first patents issued to Tesla in the US, and building and installing the system in Rahway, New Jersey Tesla's new system gained notice in the technical press, which commented on its advanced features.
In Denmark wind power was an important part of a decentralized electrification in the first quarter of the 20th century, partly because of Poul la Cour from his first practical development in 1891 at Askov. By 1908 there were 72 wind-driven electric generators from 5 kW to 25 kW. The largest machines were on 24 m (79 ft) towers with four-bladed 23 m (75 ft) diameter rotors. In 1957 Johannes Juul installed a 24 m diameter wind turbine at Gedser, which ran from 1957 until 1967. This was a three-bladed, horizontal-axis, upwind, stall-regulated turbine similar to those now used for commercial wind power development.
A wind turbine is a windmill-like structure specifically developed to generate electricity. They can be seen as the next step in the development of the windmill. The first wind turbines were built by the end of the nineteenth century by Prof James Blyth in Scotland (1887), Charles F. Brush in Cleveland, Ohio (1887–1888) and Poul la Cour in Denmark (1890s). La Cour's mill from 1896 later became the local powerplant of the village Askov. By 1908 there were 72 wind-driven electric generators in Denmark, ranging from 5 to 25 kW. By the 1930s, windmills were widely used to generate electricity on farms in the United States where distribution systems had not yet been installed, built by companies such as Jacobs Wind, Wincharger, Miller Airlite, Universal Aeroelectric, Paris-Dunn, Airline, and Winpower. The Dunlite Corporation produced turbines for similar locations in Australia.
Forerunners of modern horizontal-axis utility-scale wind generators were the WIME-3D in service in Balaklava USSR from 1931 until 1942, a 100-kW generator on a 30-m (100-ft) tower, the Smith–Putnam wind turbine built in 1941 on the mountain known as Grandpa's Knob in Castleton, Vermont, United States of 1.25 MW and the NASA wind turbines developed from 1974 through the mid-1980s. The development of these 13 experimental wind turbines pioneered many of the wind turbine design technologies in use today, including: steel tube towers, variable-speed generators, composite blade materials, and partial-span pitch control, as well as aerodynamic, structural, and acoustic engineering design capabilities. The modern wind power industry began in 1979 with the serial production of wind turbines by Danish manufacturers Kuriant, Vestas, Nordtank, and Bonus. These early turbines were small by today's standards, with capacities of 20–30 kW each. Since then, commercial turbines have increased greatly in size, with the Enercon E-126 capable of delivering up to 7 MW, while wind turbine production has expanded to many countries.
Burton Wold Wind Farm was the first to be erected in Northamptonshire. Construction work on the site began in December 2005, and the wind farm became operational in May 2006. It comprises 10 turbines with a total nameplate capacity of 20 megawatts. These 10 turbines have the ability to produce electricity for an average of 10,000 homes each year, the equivalent of 25% of all the homes in the borough of Kettering. The E70-E4 turbines were supplied by Enercon Gmbh of Germany, who are one of the leading manufacturers of wind turbines in the world. Each turbine is 64 meters tall to the hub, the rotor blades have a diameter of 71 meters which gives the turbines an overall height from the ground to the vertical tip of a blade of 99.5 meters.
In 1977 Boeing won the NASA and US-DOE contract for the design, fabrication, construction, installation and testing of several 2.5-megawatt wind turbine models in the United States. The first four MOD-2 models went into operation during the early 1980s. The dedication ceremony for the first three turbines was held on April 17, 1980, at Goodnoe Hills, Washington. On September 2, 1982, a fourth began operating at Medicine Bow, Wyoming. The Bonneville Power Administration bought the generated electricity of the Goodnoe Hills turbines and integrated it into the regional power grid. During the periods of May 1981, the three turbines at the Goodnoe Hills site formed the first wind farm in the world. The Goodnoe Hills site was primarily a research project for Boeing, Bonneville Power Administration, NASA and the Battelle Memorial Institute. The Solar Energy Research Institute also evaluated the suitability of megawatt-class wind turbines as a source of electricity. During 1986, the MOD-2 wind turbines of Goodnoe Hills were dismantled. In 1985, the last full year of operation, the combined electrical output of the three turbines was 8,251 megawatt-hours. The Medicine Bow MOD-2 wind turbine was sold for scrap in 1987. In 2008, the Goodnoe Hills Wind Farm opened on the same site with 47 REpower 2.0 MW wind turbines for a combined nameplate capacity of 94 MW. enXco/Power Holdings owns the wind farm, with PacifiCorp as the power purchaser.
