Southwest Windpower
Southwest Windpower (SWWP) was a wind turbine manufacturer established in 1987 based in Flagstaff, Arizona, United States. The company specialized in small, reliable battery charging wind generators that complement photovoltaics (solar energy or PV) in supplying energy to rural areas. Southwest Windpower closed for business in the first quarter of 2013. The remaining Skystream assets were acquired by Xzeres wind in July 2013. Xzeres CEO Frank Greco had been the CEO of Southwest Windpower. Certifications In 2000, SWWP became the first wind turbine manufacturer to receive Underwriters Laboratories (UL) and International Electrotechnical Commission (IEC) certification, for its AIR series wind turbines. Southwest Windpower’s latest turbine, the Skystream 3.7, has a rotor diameter of about and can generate up to half an average U.S. home's energy in optimal winds. It is the first residential-scale wind generator designed specifically for the grid-connected home or small business ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Engineering Companies Of The United States
Engineering is the practice of using natural science, mathematics, and the engineering design process to solve problems within technology, increase efficiency and productivity, and improve systems. Modern engineering comprises many subfields which include designing and improving infrastructure, machinery, vehicles, electronics, materials, and energy systems. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis for applications of mathematics and science. See glossary of engineering. The word ''engineering'' is derived from the Latin . Definition The American Engineers' Council for Professional Development (the predecessor of the Accreditation Board for Engineering and Technology aka ABET) has defined "engineering" as: History Engineering has existed since ancient times, when humans devised inventions such as the wedge, lever, wheel and pulley, etc. The term ''engineering'' is derived f ...

Wind Turbine Manufacturers
Wind is the natural movement of air or other gases relative to a planet's surface. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth. The study of wind is called anemology. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet ( Coriolis effect). Within the tropics and subtropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can prevail. Winds are commonly classified by their spatial scale, their speed and direction, the forces that cause them, the regions in which th ...

Helium
Helium (from ) is a chemical element; it has chemical symbol, symbol He and atomic number 2. It is a colorless, odorless, non-toxic, inert gas, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the Chemical element, elements, and it does not have a melting point at standard pressures. It is the second-lightest and second-most Abundance of the chemical elements, abundant element in the observable universe, after hydrogen. It is present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this in both the Sun and Jupiter, because of the very high nuclear binding energy (per nucleon) of helium-4 with respect to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. The most common isotope of helium in the universe is helium-4, ...

Airborne Wind Turbine
An airborne wind turbine is a design concept for a wind turbine with a rotor supported in the air without a tower, thus benefiting from the higher velocity and persistence of wind at high altitudes, while avoiding the expense of tower construction, or the need for slip rings or yaw mechanism. An electrical generator may be on the ground or airborne. Challenges include safely suspending and maintaining turbines hundreds of meters off the ground in high winds and storms, transferring the harvested and/or generated power back to earth, and interference with aviation. Airborne wind turbines may operate in low or high altitudes; they are part of a wider class of Airborne Wind Energy Systems (AWES) addressed by high-altitude wind power and crosswind kite power. When the generator is on the ground, then the tethered aircraft need not carry the generator mass or have a conductive tether. When the generator is aloft, then a conductive tether would be used to transmit energy to the gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Germanischer Lloyd
The was a classification society based in Hamburg, Germany. It ceased to exist as an independent entity in September 2013 as a result of its merger with Norway's DNV (Det Norske Veritas) to become DNV GL. Before the merger, as a technical supervisory organization, Germanischer Lloyd conducted safety surveys on more than 7,000 ships with over 100 Mio GT. Its technical and engineering services also included the mitigation of risks and assurance of technical compliance for oil, gas, and industrial installations, as well as wind energy parks. History On 16 March 1867, a group of 600 shipowners, shipbuilders and insurers met in the big hall of the Hamburg Stock Exchange on the occasion of the founding convention of Germanischer Lloyd. On behalf of the founding committee, the merchant and shipowner August Behn signed the statute of the young institution. The founding committee consisted of representatives of shipowners J. C.

Megawatt Hour
A kilowatt-hour (unit symbol: kW⋅h or kW h; commonly written as kWh) is a non-SI unit of energy equal to 3.6 megajoules (MJ) in SI units, which is the energy delivered by one kilowatt of power for one hour. Kilowatt-hours are a common billing unit for electrical energy supplied by electric utilities. Metric prefixes are used for multiples and submultiples of the basic unit, the watt-hour (3.6 kJ). Definition The kilowatt-hour is a composite unit of energy equal to one kilowatt (kW) multiplied by (i.e., sustained for) one hour. The International System of Units (SI) unit of energy meanwhile is the joule (symbol J). Because a watt is by definition one joule per second, and because there are 3,600 seconds in an hour, one kWh equals 3,600 kilojoules or 3.6 MJ."Half-high dots or spaces are used to express a derived unit formed from two or more other units by multiplication.", Barry N. Taylor. (2001 ed.''The International System of Units.'' (Special publication 330). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
