That's 12.21 gigawatts! Can't you just hear the professor saying "twelve point twenty one"!
- No, it's not. He says "one point twenty-one". Bttf4444 22:34, 7 November 2008 (UTC)
- I'm guilty of opening the door for speculation about what was "suggested" by the ending of Back to the Future. Watching it in the theater in 1985, I came away with the impression that the brief glimpse of the future suggested that someday, cars would have a little reactor on the back and that we wouldn't have to pay $1.29 for a gallon of gas. Doc's rummaging through the garbage, Marty asks him what he's doing, and he says "I need fuel!" and then puts beer and then the can into Mr. Fusion. I was right about not paying $1.29 per gallon in the future, but the 1989 sequel explained that cars didn't operate on Mr. Fusion units and that there would still be gas stations in 2015. Still, the Texaco station is offering something to do with fusion power in addition to its gasoline. Thoughts, anyone?
- It seems a lot of people were confused about the purpose of Mr. Fusion. One printed book of movie bloopers that was published between the release of BTTF II and BTTF III claimed it was a mistake that there were gas stations in 2015, asking, "What do cars run on in the future, gasoline or fusion?" Seeing a purchased-over-the-counter fusion reactor on the back of a car is an outlandish visual joke that violates the known laws of physics, so audiences forgot that a car only runs on 170 horsepower (126,800 watts), which is miniscule compared to a fusion or fission reactor. (Maybe fusion provides the energy needed for cars that were built to fly but hoverconverted road cars still needed gasoline to drive on the ground.) Audiences also seemed to forget that Doc Brown had said "one pellet, one trip" and he had to load 1.21 Gw of fuel between time travel trips. They also didn't notice that it's a "home" energy reactor and it incongruously sticks up where Doc had loaded the plutonium. Western Union 16:46, 11 June 2009 (UTC)
