Finally! A use for junk mail.

Well, we won't have the Miami Gators going to the AL. That spot was filled by the Astros.

Sony's engineers are not the only ones exploring the concept of paper-based batteries.

In 2009 a team of Stanford University scientists revealed they were working on a battery created by coating sheets of paper with ink made of carbon nanotubes and silver nanowires. They said their work might ultimately lead to a device capable of lasting through 40,000 charge-discharge cycles.

JEEZ "science" writers. This "battery" appears to be a fuel cell in which paper is a chemical component that winds up being oxidized. The Stanford effort is actually a battery in which paper is a STRUCTURAL component.

And what about the Ink on these papers?

timharrod: Presumably the flight gear is also gas-powered.

Lighting destroyed the flying circuits and damaged he time circuits. That is why 1955 doc built that mass of tubes on the hood.

Sony's prototype looks pretty promising. I'd wager it's only 5-10 years from commercial release.

Well....

Baron Harkonnen: And why was the DeLorean powered by Mr. Fusion at the end of Back to the Future (Doc Brown dumps a half-drunk beer can into the DeLorean to power it then), but in Back to the Future III, the DeLorean goes back to being a gasoline powered car that can't fly?

/And Doc Brown, the inventor of time travel, is unable to convert kerosene into a usable gasoline substitute that just needed to function for a few minutes.

Before Marty went back, he didn't have the parts to rebuild the time circuits - and he'd already made his peace with staying in that time period, so he didn't have a thought to making his own gasoline. When Marty arrived, they only had ~five days or a week before Doc would get shot. Of course, you might point out they might have longer if Doc just holed up and avoided Tannen until everything was ready, but that would have been risky (more risky than trying alternatives, like a too-powerful alcohol for a fuel, to get up to speed).

That said, I don't know how long it would take to convert kerosene into a gasoline substitute, though I'm pretty sure the second first thing they tried destroyed some part that would take Doc 'a month to rebuild.'

Oh yeah, I forgot about those! Loved that show when I was a pup

Cubs still suck.

Disney did it better.

Anything that needs fed needs to poop as well. Where does this battery poop?

So how much waste paper do you have to feed this to get 1.21 gigawatts?

Why try to convert kerosene to gasoline? Gasoline was a natural byproduct of many hydrocarbon cracking methods in use at the time. In fact, the first gasoline pump was put into service in September of 1885 (hand powered, and only stored one barrels worth). Doc Brown could have gotten his gasoline from the same place the town store got their kerosene.

BECAUSE ITS A FARKING MOVIE YOU ASSWAD.

Seriously, get a better hobby nerdlinger.

Aratech 74-Z speeder bike or GTFO.

/Goddamn better not be obscure.

There was another simple solution in BTTF 3. When Marty goes back to rescue Doc, there are actually two Deloreans present. The one Marty traveled back in, and the same one Doc hid in the cave to be discovered in 1955. All they had to do was syphon some gas from that one, and then leave it there as he did before.
