Mark Quashie (born January 24, 1967), better known as The Mad Stuntman, is a multi-platinum selling American electronic dance artist born in Trinidad and Tobago.
 Quashie's moniker was inspired by the 1980s action/adventure television program "The Fall Guy" which starred actor Lee Majors as a Hollywood stuntman, moonlighting as a bounty hunter.
 Making his home in Brooklyn, NY, The Mad Stuntman was introduced to platinum-selling producer/DJ Erick Morillo by popular Panamanian reggae artist El General, who is dubbed the "Father of Reggaeton".
 Morillo was looking for an act to be featured on his upcoming single "Go On Move" and to ultimately join him on tour as a group.
The water engine is a positive-displacement engine, often closely resembling a steam engine with similar pistons and valves, that is driven by water pressure.
 The supply of water was derived from a natural head of water, the water mains, or a specialised high-pressure water supply such as that provided by the London Hydraulic Power Company.
 Water mains in the 19th century often operated at pressures of 30 to 40 psi, while hydraulic power companies supplied higher pressure water at anything up to 800 psi.
The Water Engine is a 1992 television film based on David Mamet's play of the same name.
