This article: The sea offers a very large supply of energy carried by ocean waves, tides, salinity differences, and ocean temperature differences which can be harnessed to generate electricity. Forms of 'green' marine energy include tidal power, marine current power, osmotic power, ocean thermal energy and wave power. Tidal power uses generators to produce electricity from tidal flows, sometimes by using a dam to store and then release seawater. The Rance barrage, 1 kilometre (0.62 mi) long, near St Malo in Brittany opened in 1967; it generates about 0.5 GW, but it has been followed by few similar schemes.The large and highly variable energy of waves gives them enormous destructive capability, making affordable and reliable wave machines problematic to develop. A small 2 MW commercial wave power plant, "Osprey", was built in Northern Scotland in 1995 about 300 metres (1000 ft) offshore. It was soon damaged by waves, then destroyed by a storm. Marine current power could provide populated areas close to the sea with a significant part of their energy needs. In principle, it could be harnessed by open-flow turbines; sea bed systems are available, but limited to a depth of about 40 metres (130 ft).Offshore wind power is captured by wind turbines placed out at sea; it has the advantage that wind speeds are higher than on land, though wind farms are more costly to construct offshore. The first offshore wind farm was installed in Denmark in 1991, and the installed capacity of European offshore wind farms reached 3 GW in 2010.Electricity power stations are often located on the coast or beside an estuary so that the sea can be used as a heat sink. A colder heat sink enables more efficient power generation, which is important for expensive nuclear power plants in particular. contains an answer for the question: What type of power does the Rance barrage provide?, what is it ?
Ans: Tidal power

This article: During the rage of Hurricane Katrina, Detective Andy Devereaux discovers the body of his former partner in a close to underwater warehouse. Quickly forgetting about his discovery, he joins a newly transferred detective named Stan Johnson (Curtis "50 Cent" Jackson) trying to end a conflict involving looters. Post-Katrina, Andy and Stan are now partners. They work with corrupt detectives Pepe and Barney, who are caught up in the murder of an undercover narcotics agent. Investigating the escalating police corruption in New Orleans is FBI Agent Brown. Brown brings up his thoughts to Police Captain Friendly who insists he is doing his best to solve the problems in his department. Meanwhile, police therapist Nina Ferraro tries to help the detectives with their struggles, with little avail. She is particularly interested in Andy, whose father, also a detective, was murdered in the line of duty. Things are complicated further with Agent Brown's investigation into Andy and his crew. Brown tells Andy that he has an informant who is leaking out the details, and Andy, disbelieving at first, begins to resign himself to the fact that one of his men is betraying him. After Captain Friendly is assassinated by a local gangster named Chamorro, Andy, Stan, Pepe, and Barney decide to take the law into their own hands and go after Chamorro. While interrogating Chamorro, they find out that Brown has been supplying the drug dealer with information about the police raids, to help his own investigation. In a violent shootout, Barney accidentally shoots and kills Pepe. Andy and Stan escape, only to return to the warehouse where they met. There Andy realizes that Stan is the informant. After the two start arguing, Brown shows up and there is another shootout, ending in Brown's death. Andy comforts a sobbing Stan, then Andy kills his partner, as he possibly did with his previous one. contains an answer for the question: What is the rank of the man the drug dealer kills?, what is it ?
Ans: Captain

This article: In London, Grainger's charm, good looks and talent (with some assistance from the local Australian community) ensured that he was quickly taken up as a pianist by wealthy patrons. He was soon performing in concerts in private homes. The Times critic reported after one such appearance that Grainger's playing "revealed rare intelligence and a good deal of artistic insight". In 1902 he was presented by the socialite Lillith Lowrey to Queen Alexandra, who thereafter frequently attended his London recitals. Lowrey, 20 years Grainger's senior, traded patronage and contacts for sexual favours he termed the relationship a "love-serve job". She was the first woman with whom he had sex; he later wrote of this initial encounter that he had experienced "an overpowering landslide" of feeling, and that "I thought I was about to die. If I remember correctly, I only experienced fear of death. I don't think that any joy entered into it".In February 1902 Grainger made his first appearance as a piano soloist with an orchestra, playing Tchaikovsky's first piano concerto with the Bath Pump Room Orchestra. In October of that year he toured Britain in a concert party with Adelina Patti, the Italian-born opera singer. Patti was greatly taken by the young pianist and prophesied a glorious career for him. The following year he met the German-Italian composer and pianist Ferruccio Busoni. Initially the two men were on cordial terms (Busoni offered to give Grainger lessons free of charge) and, as a result, Grainger spent part of the 1903 summer in Berlin as Busoni's pupil. However, the visit was not a success; as Bird notes, Busoni had expected "a willing slave and adoring disciple", a role Grainger was not willing to fulfill. Grainger returned to London in July 1903; almost immediately he departed with Rose on a 10-month tour of Australia, New Zealand and South Africa, as a member of a party organised by the Australian contralto Ada Crossley. contains an answer for the question: What is the last name of the pianist who offered the man with "rare intelligence" free lessons?, what is it ?
Ans: Busoni
