The flux capacitor is the core component of Doctor Emmett Brown's time traveling De Lorean DMC-12 in the 1985 movie Back to the Future, its two sequels, and the animated series. Brown states that the flux capacitor "is what makes time travel possible."
It is not made clear in the movie exactly how the flux capacitor works. It consists of a box with three small, flashing incandescent lamps arranged as a "Y", located above and behind the passenger's seat of the time machine. As the car nears 88 miles per hour, the light of the flux capacitor pulses faster until it has a steady stream of light. The stainless steel body of the De Lorean also has a beneficial effect on the "flux dispersal" as the capacitor activates, although Doc is interrupted before he can finish explaining it fully.
At the end of the third film in the series, when Doc Brown has converted a locomotive into a time machine, the flux capacitor is located on the front of the train, in place of the lamp.
Spoiler warning: Plot and/or ending details follow.
On November 5 1955, Doc Emmett Brown came up with the idea of the flux capacitor after slipping and bumping his head while standing on his toilet to hang a clock. The idea came to him in a vision he had after being knocked out.
In order to travel through time, the vehicle integrated with the flux capacitor needs to be travelling at 88 mph (140.8 km/h), and requires 1.21 gigawatts of power (1 210 000 000 watts), originally supplied by a plutonium-powered nuclear reactor. However, for the time machine's return trip (from 1955 back to 1985), plutonium was not available, so a lightning rod was connected directly to the flux capacitor and was used while the vehicle sustained 88 mph. Plutonium was used once again for a trip forward in time at least 30 years, and at some point thereafter the plutonium reactor was replaced by a "Mr. Fusion" home energy generator from the future that was fueled by extracting hydrogen atoms from garbage.
The DeLorean once again came back to 1985 and proceeded to travel to 2015, where it was stolen and taken back to 1955 and returned back to 2015 without the Doc's knowledge. When they returned in 1985, they found it was a different present, so they traveled back to 1955 to fix the timeline. The De Lorean was again struck by lightning in the year 1955, this time by accident. The lightning created an overload and destroyed the time circuits, causing a random time to be selected which sent the De Lorean back to 1885. It was then hidden in the Delgado mine for 70 years, "... because suitable replacement parts will not be invented until 1947." This is presumably a reference to the invention of the transistor. It was recovered from the mine in 1955 and repaired by Doc Brown's 1955 counterpart, thus restoring it to working order. Since both gasoline and garbage were available, the next trip back to 1885 was performed under the car's own power.
Due to lack of gasoline and a broken fuel line, the De Lorean's final trip from 1885 to 1985 was partially powered by a steam locomotive pushing the vehicle up to 88 mph while using Mr. Fusion to generate the 1.21 gigawatts required to activate the Flux Capacitor and break the Time barrier. At the very end of the third movie, Doc returns to 1985 in a time machine made from a train. This uses a flux capacitor that Doc was able to power using steam.

Every capacitor has actually a flux running through it. That does not make it a "flux capacitor" as used in Back to the Future, though. :-)
You CAN travel back in time as long as you store every state of the universe along the way. See more about that in the Scientific American article about Time Travel from 2002, and later issues.

Stand on your toilet, fall over so you hit your head on the sink. When you wake up you'll know all about the Flux Capacitor
And we all know that that's what makes time travel possible.

Call Michael J. Fox; I think they let him keep the car with one in it after the movies were over. He would let you make a donation to his charity for it most likely.
