Lester Allan Pelton (September 5, 1829 – March 14, 1908) was an American inventor who contributed significantly to the development of hydroelectricity and hydropower in the American Old West as well as world-wide. In the late 1870s, he invented the Pelton water wheel, at that time the most efficient design of the impulse water turbine.
A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation.
The U.S. Chemical Safety Board (CSB) highlighted flaws in both equipment and industry safety procedures, contributing to the oil spill in its report. [51] The CSB concluded that a primary contributor to the spill was a malfunctioning blowout preventer (BOP). The investigation discovered that the BOP malfunctioned due to miswired control systems ...
Deepwater Horizon was an ultra-deepwater, dynamically positioned, semi-submersible offshore drilling rig [7] owned by Transocean and operated by the BP company. On April 20, 2010, while drilling in the Gulf of Mexico at the Macondo Prospect, a blowout caused an explosion on the rig that killed 11 crewmen and ignited a fireball visible from 40 miles (64 km) away.

The Pelton wheel or Pelton Turbine is an impulse -type water turbine invented by American inventor Lester Allan Pelton in the 1870s. [1][2] The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many earlier variations of impulse turbines existed, but they ...
June 1 – Oil began washing up on the beaches of Gulf Islands National Seashore. [88] June 4 – Tar balls arrive on beaches in Pensacola, Florida. [89] June 5 – Obama makes third trip to Louisiana since the disaster began, visits Grand Isle, Louisiana for the second time in two weeks.
Caused in the aftermath of a blowout and explosion on the Deepwater Horizon oil platform, the United States federal government estimated the total discharge at 4.9 MMbbl (210,000,000 US gal; 780,000 m 3). [ 3 ] After several failed efforts to contain the flow, the well was declared sealed on 19 September 2010. [ 10 ]
An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution. The term is usually given to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on land. Oil spills can result from the release ...
