Doc: Hey, hey, keep rolling, keep rolling there. No, no, no, no, this
sucker's electrical. But I

need a nuclear reaction to generate the one point twenty-one gigawatts
of electricity that I need.

Marty: Uh, plutonium, wait a minute, are you telling me that this
sucker's nuclear?

Doc: Unfortunately no, it requires something with a little more kick,
plutonium.

Marty: This is uh, this is heavy duty, Doc, this is great. Uh, does it
run on regular unleaded

gasoline?

Doc: It's taken me almost thirty years and my entire family fortune to
realize the vision of that

day, my god has it been that long. Things have certainly changed around
here. I remember

when this was all farmland as far as the eye could see. Old man Peabody,
owned all of this.

He had this crazy idea about breeding pine trees.

Marty: The flux capacitor.

Doc: That was the day I invented time travel. I remember it vividly. I
was standing on the edge

of my toilet hanging a clock, the porces was wet, I slipped, hit my head
on the edge of the sink.

And when I came to I had a revelation, a picture, a picture in my head,
a picture of this. This is

what makes time travel possible. The flux capacitor.

Marty: What, I don't get what happened.

Doc: He's fine, and he's completely unaware that anything happened. As
far as he's concerned

the trip was instantaneous. That's why Einstein's watch is exactly one
minute behind mine. He

skipped over that minute to instantly arrive at this moment in time.
Come here, I'll show you

how it works. First, you turn the time circuits on. This readout tell
you where you're going, this

one tells you where you are, this one tells you where you were. You
imput the destination time

on this keypad. Say, you wanna see the signing of the declaration of
independence, or witness

the birth or Christ. Here's a red-letter date in the history of science,
November 5, 1955. Yes, of

course, November 5, 1955.

Marty: He's alright.
