Sorcha Mowbray Biography & Facts
In the Back to the Future franchise, the DeLorean time machine is a time travel device made by retrofitting a DMC DeLorean vehicle with a flux capacitor. The car requires 1.21 gigawatts of power and needs to travel 88 miles per hour (142 km/h) to initiate time travel.
The control of the time machine is the same in all three films. The operator is seated inside the DeLorean (except the first time, when the remote control is used), and turns on the time circuits by turning a handle near the gear lever, activating a unit containing multiple fourteen- and seven-segment displays that show the destination (red), present (green), and last departed (yellow) dates and times. After entering a target date with the keypad inside the DeLorean, the operator accelerates the car to 88 miles per hour (141.6 km/h), which activates the flux capacitor. As it accelerates, several coils around the body glow blue/white while a burst of light appears in front of it. Surrounded by an electrical current similar to a Tesla coil, the whole car vanishes in a flash of white/blue light seconds later, leaving a pair of fiery tire tracks. A digital speedometer is attached to the dashboard so that the operator can accurately gauge the car's speed. Various proposals have been brought forth in the past by fans of the movie franchise for why the car has to be moving at 88 mph to achieve temporal displacement, but actually the production crew chose the velocity simply because they liked how it looked on the speedometer, modified for the movie. The actual speedometer on the production DeLorean's dashboard only goes up to 88 mph, and the car itself was criticized for being underpowered by plutonium.
Observers outside the vehicle see an implosion of plasma as the vehicle disappears, leaving behind a trail of fire aligned with the DeLorean's tires (which can also appear in midair), while occupants within the vehicle see a quick flash of light and instantaneously arrive at the target time in the same spatial location (relative to the Earth) as when it departed. In the destination time, immediately before the car's arrival, three large and loud flashes occur at the point from which the car emerges from its time travel. After the trip, the exterior of the DeLorean is extremely cold, and frost forms from atmospheric moisture all over the car's body. Vents on the back heat the vehicle after time travel.
A few technical glitches with the DeLorean hinder time travel for its users. In the first film, the car has starter problems and has a hard time restarting once stopped, much to Marty's repeated frustration. In the second movie, the destination time display malfunctions and shows random dates (mostly January 1, 1885), which partially cause Doc to be sent to 1885. In the third movie, the flying circuits (added by Doc in 2015), fuel line, and fuel injection manifold are damaged, preventing the car from moving under its own power.
The time machine is electric and requires a power input of 1.21 gigawatts (1,620,000 hp) to operate, originally provided by a plutonium-fueled nuclear reactor. In the first movie, following Marty's accidental trip from 1985 to 1955, Doc has no access to plutonium in 1955, so he outfits the car with a large pole and hook in order to channel the power of a lightning bolt into the flux capacitor and send Marty back to 1985. During Doc's first visit to 2015, he has the machine refitted to fly in addition to standard road driving, and he replaces the nuclear reactor with a Mr. Fusion generator that uses garbage as fuel.Although the Mr. Fusion unit provides the required power for the time machine, the DeLorean is still powered by an internal combustion engine for propulsion. The fuel line is damaged during Marty's trip to 1885 in Back to the Future Part III; after he and Doc patch it, they attempt to use whiskey as a replacement fuel since commercial gasoline is not yet available. The test fails, damaging the car's fuel injection manifold and leaving it unable to travel under its own power.
Doc and Marty consider options to reach the required 88 mph (such as pulling it with horses, which fails because the car barely breaks 30 mph) and ultimately settle on pushing the car with a steam locomotive. They replace the DeLorean's standard wheels with a set designed to mate with train rails. For the extra power needed to push it up to speed, Doc adds his own version of "Presto Logs" (a chemically treated mixture of pressed wood and anthracite) to the locomotive's boiler and chooses a location with a straight section of track long enough to achieve 88 mph.
The power required is pronounced in the film as "one point twenty-one jigowatts", with a jigowatt referring to "one billion watts." The spelling of jigowatts is used in the script and was also the spelling used in the closed-captioning in earlier home video versions of the film. However, the correct spelling is "gigawatts". Although rarely used, the "j" sound at the beginning of the SI prefix "giga-" is an acceptable pronunciation. Later versions of closed captioning, such as in the 2020 DVD Trilogy release have corrected the spelling to gigawatts. In the DVD commentary for Back to the Future, Bob Gale states that he had thought it was pronounced this way because it was how a scientific adviser for the film pronounced it.
The flux capacitor, which consists of a rectangular-shaped compartment with three flashing Geissler-style tubes arranged in a "Y" configuration, is described by Doc as "what makes time travel possible." The device is the core component of the time machine.As the time machine nears 88 mph, light coming from the flux capacitor begins pulsing more rapidly until it becomes a steady stream. Doc originally conceived the idea for the flux capacitor on November 5, 1955, when he slipped on the edge of his toilet while hanging a clock in his bathroom and hit his head on the sink. A similar, but possibly steam-powered, flux capacitor is also seen in the chimney headlamp of Doc's second time machine, the Time Train, at the end of Back to the Future Part III.Although the films do not describe exactly how the flux capacitor works, Doc mentions at one point that the stainless steel body of the DeLorean has a direct and influential effect on the "flux dispersal", but he is interrupted before he can finish the explanation. The flux capacitor requires 1.21 gigawatts of electrical power to operate, which is roughly equivalent to the power produced by 15 typical commercial airplane jet engines.
The instruction manual for the AMT/ERTL DeLorean model kit says: "Because the car's stainless steel body improves the flux dispersal generated by the flux capacitor, and this in turn allows the vehicle smooth passage through the space-time continuum."
The time circuits are an integral part of the DeLorean time machine. They were built with an input device and a display. The display was divided into.... Discover the Sorcha Mowbray popular books. Find the top 100 most popular Sorcha Mowbray books.
