Harkleroad Wind Turbine
The Harkleroad wind turbine is a wind turbine in Novato, California. It was built to generate electricity. It appears in Northern California along U.S. Route 101, a heavily traveled freeway. Around 1960, Sam Harkleroad designed and constructed three unusual structures on a plot of land in Novato, Marin County, California: * A round home that rotates * A home built in 1959, with a roof shaped as a hyperbolic paraboloid * A workshop building, with the Harkleroad wind turbine on the roof Sam Harkleroad Sam Harkleroad was born on October 20, 1909, and grew up on a farm in Fresno.

Sam and his wife were very nice people, they had a Daughter, Renee Israel. Harkleroad was a contractor, who liked to use recycled materials. The Harkleroad structures are on a street named Harkle Road. Round house The round house once appeared in a Popular Mechanic ...

Novato, California
Novato (Spanish for "Novatus") is a city in Marin County, California, in the North Bay region of the Bay Area. At the 2020 census, Novato had a population of 53,225.

Mexican era In 1839, the Mexican government granted the Rancho Novato to Fernando Feliz. The rancho was named after a local Miwok leader who had probably been given the name of Saint Novatus at his baptism. Subsequently, four additional land grants were made in the area: Rancho Corte Madera de Novato, to John Martin in 1839; Rancho San Jose, to Ignacio Pacheco in 1840; Rancho Olómpali, awarded in 1843 to Camilo Ynitia, son of a Coast Miwok chief; and Rancho Nicasio, by far the largest at , awarded to Pablo de la Guerra and John B.R.

The Los Angeles Times
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

Hyperbolic Paraboloid
In geometry, a paraboloid is a quadric surface that has exactly one axis of symmetry and no center of symmetry. The term "paraboloid" is derived from parabola, which refers to a conic section that has a similar property of symmetry. Every plane section of a paraboloid by a plane parallel to the axis of symmetry is a parabola. The paraboloid is hyperbolic if every other plane section is either a hyperbola, or two crossing lines (in the case of a section by a tangent plane). The paraboloid is elliptic if every other nonempty plane section is either an ellipse, or a single point (in the case of a section by a tangent plane). A paraboloid is either elliptic or hyperbolic. Equivalently, a paraboloid may be defined as a quadric surface that is not a cylinder, and has an implicit equation whose part of degree two may be factored over the complex numbers into two different linear factors. The paraboloid is hyperbolic if the factors are real; elliptic if the factors are complex conjugate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 range of ...

Saddle Roof
A saddle roof is a roof form which follows a convex curve about one axis and a concave curve about the other. The hyperbolic paraboloid form has been used for roofs at various times since it is easily constructed from straight sections of lumber, steel, or other conventional materials. The term is used because the form resembles the shape of a saddle. Sometimes referred to as a hypar, the saddle roof may also be formed as a tensegrity structure. Mathematically, a saddle shape contains at least one saddle point. The historical meaning is a synonym for a gable roof particularly a ''dual-pitched'' roof on a tower, also called a ''pack-saddle roof''.Passmore, Augustine C.. "Saddle Roof".
