saab 2000
Saab decided to build the 2000 in December 1988 due to perceived demand for a high speed turboprop which could approach the speeds of jet aircraft while retaining the efficiency provided by turboprop engines. The Saab 2000 first flew on 26 March 1992 and entered into scheduled airline service in 1994, a few months after its certification by the Joint Aviation Authorities in March and the Federal Aviation Administration in April.
The Saab 2000 had a 15% greater wingspan than the Saab 340, and being over 24 ft. 9 in. (7.55m) longer could fit up to 50 passengers. The 2000 was the first commercial aircraft to use the 4,591shp Rolls-Royce AE 2100 turboprop engines (then built by Allison), driving slow turning six-bladed Dowty Rotol propellers. One engine was mounted on each wing, as in the 340, with the engines placed farther from the fuselage than those of the 340.
Sales of the Saab 2000 were fairly limited. The major initial customer was Crossair, a regional airline which had Swissair as a 56% shareholder. Crossair took delivery of 34 aircraft and was still operating the type in 2005. Due to limited demand, Saab ceased production of the Saab 2000 in 1999.
By the year 2000, 54 Saab 2000 aircraft remained in service. The primary reason for the low sales was the success of the newly introduced low-cost regional jets such as the Bombardier CRJ and Embraer ERJ 145 family which provided better performance and passenger comfort for the same initial price. Some smaller airlines, including Eastern Airways in the UK, have subsequently acquired 2000s at low cost and operated them on regional routes which experience lower passenger numbers.
In June 2006, Pakistan finalized the purchase of six Saab 2000 turboprop aircraft to be equipped with the Saab-Ericsson ERIEYE Airborne Early Warning system. Revised in May 2007 due to renegotiation with the Government of Pakistan, only five aircraft will be delivered, four of which will be equipped with the Erieye system. On April 3, 2008, the first Saab 2000 Erieye AEW&C was rolled out and presented to Pakistan Air Force officials during a ceremony in Sweden.

tesla
Nikola Tesla (Serbian Cyrillic: Никола Тесла; 10 July 1856 – 7 January 1943) was an inventor, mechanical engineer, and electrical engineer. He was an important contributor to the birth of commercial electricity, and is best known for his many revolutionary developments in the field of electromagnetism in the late 19th and early 20th centuries. Tesla's patents and theoretical work formed the basis of modern alternating current (AC) electric power systems, including the polyphase system of electrical distribution and the AC motor. This work helped usher in the Second Industrial Revolution.
Born an ethnic Serb in the village of Smiljan (now part of Gospić), in the Croatian Military Frontier of the Austrian Empire (modern-day Croatia), Tesla was a subject of the Austrian Empire by birth and later became an American citizen. Because of his 1894 demonstration of wireless communication through radio[citation needed] and as the eventual victor in the "War of Currents", he was widely respected as one of the greatest electrical engineers who worked in America. He pioneered modern electrical engineering and many of his discoveries were of groundbreaking importance. In the United States during this time, Tesla's fame rivaled that of any other inventor or scientist in history or popular culture. Tesla demonstrated wireless energy transfer to power electronic devices as early as 1893[citation needed], and aspired to intercontinental wireless transmission of industrial power in his unfinished Wardenclyffe Tower project.
Because of his eccentric personality and his seemingly unbelievable and sometimes bizarre claims about possible scientific and technological developments, Tesla was ultimately ostracized and regarded as a mad scientist by many late in his life. Tesla died with little money at the age of 86 in a hotel suite in New York City.
The SI unit measuring magnetic field B (also referred to as the magnetic flux density and magnetic induction), the tesla, was named in his honor (at the CGPM, Paris, 1960).
Tesla was born to Serbian parents in the village of Smiljan, Austrian Empire near the town of Gospić, in the territory of modern-day Croatia. His baptismal certificate reports that he was born on 28 June (N.S. 10 July), 1856, to Father Milutin Tesla, a priest in the Serbian Orthodox Church. His paternal origin is thought to be either of one of the local Serb clans in the Tara valley or from the Herzegovinian noble Pavle Orlović. His mother, Đuka, daughter of a Serbian Orthodox Church priest, came from a family domiciled in Lika and Banija, but with deeper origins to Kosovo. She was talented in making home craft tools and memorized many Serbian epic poems, but never learned to read.

maserati gt
Maserati 5000 GT (1959–1965) were thirty-four 2-door coupé automobiles, made by Maserati of Italy.
The first car in the Tipo 103 series, was the Shah of Persia, delivered to Mohammad Reza Pahlavi, who had been impressed by the Maserati 3500. He commissioned Maserati's chief engineer Giulio Alfieri to utilize a slightly modified 5-litre engine from the Maserati 450S on the 3500GT's chassis. Carrozzeria Touring developed the superleggera tubing and aluminum body of the two-seater coupe. The second car, also by Touring, was displayed at Salone dell'automobile di Torino 1959.
In 1960 the engine got some modifications and received a displacement of 4940cc with a bigger stroke and a smaller bore; in the new configuration engine developed 340 bhp. After three bodies by Touring, the main body partner since 1960 became Carrozzeria Allemano which did 22 of the cars. Other builders were Pietro Frua (3), Carrozzeria Monterosa (2), Pininfarina (1), Ghia (1), Michelotti (1) and Bertone (1). At least one convertible Allemano was made.
The 5000 GT was sold at prices around USD 17000 (twice the cost of a Maserati 3500), and in many respects individualized to the desires of its celebrity buyers, including Aga Khan, Italian industrialist Gianni Agnelli, sportsman Briggs Cunningham, actor Stewart Granger, Ferdinando Innocenti, Basil Read, count Giuseppe Comola, and president Adolfo López Mateos. Over time, some of the cars were added to Alfredo Breners collection, that was auctioned in 2003.
