Two aeroderivative gas turbine generators produced by GE Aircraft Engines in Evendale are providing power for the Queen Mary II, the world's largest and most expensive transatlantic liner, which set sail Monday for Fort Lauderdale, Fla., from Southhampton, England. The LM2500+ generators are modified jet engines that produce power rather than thrust to run the liner's electrical system and move it through the water. The turbine generators are teamed with four diesel generators. Each of the gas turbines contributes 25 megawatts to the ship's more than 118 megawatts of power. Thousands of people lined the waterfront to wave off the 150,000-ton Cunard Line ship as it embarked on its first fare-paying passenger journey, which is expected to take 14 days. The vessel includes a spa, five swimming pools, 2,000 bathrooms, 3,000 telephones, 4,500 steps and hundreds of works of art.
