Yeah, man, let him do his thing or just off him. Don’t let him wallow in this measly existence.
Current Biff is, I’d like to think, misguided. Mad-dog Tannen, on the other hand, is just a criminal assface.
Doc found the lost city of Atlantis. They hooked him up.
With what? Even if he could mine uranium, he wouldn’t be able to enrich it significantly, much less manufacture plutonium.
Do we ever see j/giga spelled anywhere? I always thought “Jigawatts” is a unit the movie dudes just made up, that’s way bigger than “giga”.
I thought the same thing - that it was fictional
Well, I think it’s time for me to say nitey-ya’ll.
Happy St. Crispin’s Day everyone!!
Even nuclear plants use steam turbine as the final drive cycle. As do almost every coal plants. So when he said the train/time-machine runs on “steam”, that’s just vague enough to be feasible.
Most likely answer is, he refined his flux capacitor and realized version 1.0 was just incredibly inefficient. Doc probably figured out how to run a flux capacitor v 2.0 on far, far less power.
Good night.day. We few, we happy few.
Good night, dude. Henry Vee tomorrow!
I think it’s just spoken. According to Wikipedia, the estimate of 1.21 gigawatts probably is pretty close for an average lightning bolt, so they probably used a real term with an odd (to us) pronunciation.
Nite Thot, my bruther.
Good night TFG!
Happy St. Crispin’s Day everyone!!
We few, we happy few, we band of buggered! 
Except that amount of steam power produced by a nucular plant would require a coal plant the size of a small city to replicate.

Maybe. I still call bullsorrybarb on it. 
Well, he said it runs on steam, he never said it’s not nuclear. He probably replicated a version of Mr. Fusion, since refining a fissionable material will require a city-sized manufacturing facility.
Maybe he pulled the lightning trick again, went to the future, upgraded, and then returned to the past.
Of course, how would he know where lightning would strike?
Wait, so is Doc the only one in the BttF-verse, past, present and future, to discover time travel? Do other people discover time travel also?
Since Doc is by far the smartest person in this town, and they never apparently travel anywhere else, spatially speaking, how would you know? If your past changed, you’d never notice, because it had always been that way from your perspective. So unless another time traveller altered their timeline while they were outside of it (like Old Biff did), they’d never be any the wiser…
I’m just wondering, wouldn’t a great way to test time travel be to simply right a note right now that says “hi, I’m your great, great grandfather, or whatever. When you get this note, please time-travel back to 10/24/2008, Friday, 10:05PM Pacific Time.” And make a pledge, in my mind, that I’d give this note to my grandson, with explicit direction that he’d give the same note to his grandson, and so on. If no one shows up in five minutes, then time-travel is never going to be invented.
I’ll tell you in five minutes if anyone shows up.
What if it’s not invented until your great, great, great-grandson’s time?
Or what if your descendants are idiots who can’t follow simple instructions?
Nope. No one showed up. Therefore, I’ve just proven that no one invents the time machine, ever!
(Either that, or my entire bloodline gets killed off in 200 years in a flying car accident. 2 days before time machine is invented.)
