Windmill
A windmill is a structure that converts wind power into rotational energy using vanes called sails or blades, specifically to mill grain (gristmills), but the term is also extended to windpumps, wind turbines, and other applications, in some parts of the English speaking world. The term wind engine is sometimes used to describe such devices. Windmills were used throughout the high medieval and early modern periods; the horizontal or panemone windmill first appeared in Persia during the 9th century, and the vertical windmill first appeared in northwestern Europe in the 12th century. Regarded as an icon of Dutch culture, there are approximately 1,000 windmills in the Netherlands today. Forerunners Wind-powered machines may have been known earlier, but there is no clear evidence of windmills before the 9th century. Hero of Alexandria (Heron) in first-century Roman Egypt described what appears to be a wind-driven wheel to power a machine.Dietrich Lohrmann, "Von der ...

Golden Gate Park
Golden Gate Park, located in San Francisco, California, United States, is a large urban park consisting of of public grounds. It is administered by the San Francisco Recreation & Parks Department, which began in 1871 to oversee the development of Golden Gate Park. Configured as a rectangle, it is similar in shape to but 20 percent larger than Central Park in New York City, to which it is often compared. It is over three miles () long east to west, and about half a mile () north to south. With 24 million visitors annually, Golden Gate is the third most-visited city park in the United States after Central Park and the Lincoln Memorial. History Development In the 1860s, San Franciscans began to feel the need for a spacious public park similar to Central Park, which was then taking shape in New York City. Golden Gate Park was carved out of unpromising sand and shore dunes that were known as the Outside Lands, in an unincorporated area west of San Francisco's then-curren ...

Dutch Windmill (Golden Gate Park)
The Dutch Windmill is the northern of two functioning windmills, the other being Murphy Windmill, on the western edge of Golden Gate Park in San Francisco, California. It was completed in 1903, and placed on the San Francisco Designated Landmark list on December 6, 1981. History In the 1870s and 1880s, Golden Gate Park was planted on sand dunes and required substantial irrigation. In 1902, the Park Commission authorized the construction of two windmills to pump groundwater for park irrigation rather than purchasing water at exorbitant costs from the Spring Valley Water Company. The Dutch Mill was completed one year later and pumped 30,000 gallons per hour. Electric water pumps replaced the need for windmills in 1913, and the mill fell into disrepair. By the 1950s, the mill was in a state of ruin. Restoration In 1964, the San Francisco Citizens Commission for the Restoration of the Golden Gate Park Windmills was formed and led by Eleanor Rossi Crabtree, daughter of former San F ...

Agricultural Buildings And Structures In California
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals ( grains), vegetables, fruits, cooking oils, me ...

Wind Power In California
Wind power in California had initiative and early development during Governor Jerry Brown's first two terms in the late 1970s and early 1980s. The state's wind power capacity has grown by nearly 350% since 2001, when it was less than 1,700 MW. In 2016, wind energy (including that supplied by other states) supplied about 6.9% of California's total electricity needs, or enough to power more than 1.3 million households. Most of California's wind generation is found in the Tehachapi area of Kern County, California, with some large projects in Solano, Contra Costa and Riverside counties as well. California is among the states with the largest amount of installed wind power capacity. In recent years, California has lagged behind other states when it comes to the installation of wind power. It was ranked 4th overall for wind power electrical generation at the end of 2016 behind Texas, Iowa, and Oklahoma. As of 2019, California had 5,973 megawatts (MW) of wind power generating capac ...
