October 21, 2015.

 

If you are a fan of science fiction, you may or may not remember the seemingly innocuous date dialed up in a DeLorean in the Back to the Future film trilogy (the second film, to be precise). Of course, it was just a film, but just in case:

And on a slightly more serious note, one Japanese inventor has made a real-life imitation of the DeLorean from the movie. It can even run on cotton fibers made into bioethanol from old clothes! See here.

 

 

Tokyo (CNN) - Entrepreneur Michihiko Iwamoto has realized a lifelong dream: to own a DeLorean time machine.

 

And there's no better time to do so: October 21, 2015, is the date to which Doc and Marty travel in "Back to the Future II."

 

Iwamoto's, recently shipped to Japan, has been fitted with key parts: a speedometer (set to 88 mph), a flux capacitor and a Mr. Fusion, which converts trash into a renewable energy source.

 

The movie, which Iwamoto, now 51, first watched when he was 21, has made a lasting impression.

 

"I totally believed that in the future, there would be a car that runs on garbage," Iwamoto said of the scene in which Marty and Doc fly in a trash-fueled DeLorean in "Back to the Future II."

 

"But years went by, and that didn't happen. So I thought I'd develop it."

 

In 2007, Iwamoto started JEPLAN, short for Japan Environment Planning company. Its focus is developing recycling technologies, and one of its current projects, which took five years to produce, is to create bioethanol from old clothing. 

 

Simply put, cotton fibers are broken down during a fermentation process and turned into energy. The DeLorean that Iwamoto purchased runs in part on this fuel.

 

Iwamoto has taken the time machine to shopping malls across Japan to raise awareness and to collect donations of old T-shirts and jeans in order to create fuel.

 

"I wish to promote a recycling-orientated society," he said. "But more than anything, I am very happy that I could relive the scene of the movie that I saw 30 years ago."

 

Yes!! I really liked watching these Movies. Hoverboards are Awesome (Hope they make more SOON!)

Thanks Facebook news feed!

 

(But yes, I to think it's cool that back to the future day has some inaccuracies and accurate predictions)

You know whats really weird:

Back to the Future 2 is now a movie entirely about the past.

my reaction when I found out what today was:

I totally love this movie, after seeing all the images now feeling like watch it again!
