Description

From Wikipedia: "The Mr. Fusion Home Energy Reactor is the name of a power source used by the De Lorean time machine in the Back to the Future trilogy. It can be seen towards the end of Back to the Future when "Doc" Emmett Brown pulls into the McFlys' driveway after a trip to the year 2015, and is an obvious parody of Mr. Coffee machines, which were very popular at the time of filming. Ironically, the coffee maker from which the prop was made was actually made by Krups. The Mr. Fusion Home Energy Reactor converts household waste to power the time machine's flux capacitor and time circuits using nuclear fusion. (It is thought that this is cold fusion.) In the film, Mr. Fusion allows the De Lorean time machine to generate the required 1.21 gigawatts needed to travel to any point in time. The energy produced by Mr. Fusion replaces plutonium as the primary power source of the De Lorean's time travel and flight capabilities. However, as stated in Back to the Future III, the car is still driven by its original internal combustion engine. Just as with the flux capacitor itself, the Mr. Fusion may also be considered a deus ex machina, allowing the characters to sidestep the ardurous power-generation requirements that the plot of the first film hinged upon."
