Pump

A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps.

Pumps operate by some mechanism (typically reciprocating or rotary), and consume energy to perform mechanical work by moving the fluid. Pumps operate via many energy sources, including manual operation, electricity, engines, or wind power, come in many sizes, from microscopic for use in medical applications to large industrial pumps.

Mechanical pumps serve in a wide range of applications such as pumping water from wells, aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas or for operating cooling towers. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and penile prosthesis.

Pump (film)

Pump is a 2014 documentary film by Josh Tickell and Rebecca Harrell Tickell. The film explores the history of petroleum-based fuel consumption, the use of the Internal combustion engine and the geopolitics involved with petroleum. The film then explores in-depth on the alternative energy options for vehicles that are either readily available for use or can be on a mass scale.

Funding for the film came from Patrón tequila founder John Paul DeJoria, Rhino Films executive Stephen Nemeth and the Fuel Freedom Foundation.

Wind (band)

Wind is the name of a German musical group that mostly plays "schlager" music. The band is still active, more than 20 years after its foundation.

History

The group was started in 1985 by the composer Hanne Haller. The members of the band at that time were Alexander "Ala" Heiler, Christiane von Kutschenbach, Rainer Höglmeier, Willie Jakob, Sami Kalifa and Petra Scheeser.

The group has participated in the Eurovision Song Contest for Germany three times. The first time was shortly after the formation of the band, in Eurovision 1985. With the song "Für alle" ("For All") they finished second, just behind the winning duo Bobbysocks from Norway. In 1987 Wind returned to the contest, performing "Laß die Sonne in dein Herz" ("Let the Sun in Your Heart") in Brussels, Belgium. Once again they achieved a second place, this time behind Johnny Logan who represented Ireland. "Laß die Sonne in dein Herz" has since become the band's trademark tune, including welcoming visitors to their official website. Wind entered Eurovision for a third time in 1992 in Malmö, Sweden, with the song "Träume sind für alle da" ("Dreams Are For Everyone"). This time they were not as successful, finishing 16th of 23 participants. According to John Kennedy O'Connor in his book The Eurovision Song Contest: The Official History, Wind are the only act to ever finish second in the contest on two occasions.

Wind Mobile

Wind Mobile is a Canadian wireless telecommunications provider operated by Globalive. It was one of several new mobile carriers launched in Canada after a government initiative to encourage competition in the wireless sector, alongside Mobilicity (later acquired by Rogers Communications) and Public Mobile (later acquired by Telus). With 940,000 active subscribers, Wind is Canada's fourth-largest mobile operator.

Wind initially launched mobile data and voice services in the Greater Toronto and Hamilton Area, Ontario on December 16, 2009 and two days later in Calgary, Alberta. Since then, Southern Ontario has been the main target of network expansion: first with Ottawa in Q1 2011, and then with about half a dozen additional regions, the most recent being Brantford on July 3, 2014. In Western Canada, coverage was added to Edmonton, Alberta and has expanded around Edmonton to include Sherwood Park, Fort Saskatchewan, St. Albert and Edmonton International Airport; additionally, British Columbia was also added for most of Greater Vancouver area plus Abbotsford and Whistler.

Air (classical element)

Air (also sometimes called Wind) is often seen as a universal power or pure substance. Its fundamental importance to life can be seen in words such as aspire, inspire, perspire and spirit, all derived from the Latin spirare.

Greek and Roman tradition

Air is one of the four classical elements in ancient Greek philosophy and science. According to Plato, it is associated with the octahedron; air is considered to be both hot and wet. The ancient Greeks used two words for air: aer meant the dim lower atmosphere, and aether meant the bright upper atmosphere above the clouds.Plato, for instance writes that "So it is with air: there is the brightest variety which we call aether, the muddiest which we call mist and darkness, and other kinds for which we have no name...." Among the early Greek Pre-Socratic philosophers, Anaximenes (mid-6th century BCE) named air as the arche. A similar belief was attributed by some ancient sources to Diogenes Apolloniates (late 5th century BCE), who also linked air with intelligence and soul (psyche), but other sources claim that his arche was a substance between air and fire.Aristophanes parodied such teachings in his play The Clouds by putting a prayer to air in the mouth of Socrates.
