OLD BROWN: Electrical. But I need a nuclear reaction to generate the 1.21 jigowatts of electricity I need...
(YOUNG) BROWN: 1.21 JIGOWATTS? Kid, you're outta gas, going no place fast.
MARTY: Huh?
BROWN: Look, I'm sure that in 1985, plutonium is available in any corner drug store. But in 1955, it's a little hard to come by. And unless you figure on driving out into a nuclear test site while an A-bomb's going off, I'm afraid you're stuck here.
MARTY: But isn't there some other way to generate that kind of power?
BROWN: 1.21 jigowatts? Oh, sure. We can tile the Hoover Dam with a very long cable. Or we can build a turbine on the back of this thing and you can drive it over Niagra Falls. Or you can drive across the country at 88 miles an hour and hope that you get struck by a bold of lightning.
MARTY: Lightning! Hold the phone, Doc---check this out!
