DeLorean Time Machine VS the Space Shuttle
FACT: The power required to operate the Flux Capacitor in the DeLorean time machine is 1/10 that of a Space Shuttle at launch.
THE MATH BEHIND THE FACT: The power required to operate the flux capacitor is 1.21 GW gigawatts according to Dr. Emmett Brown in the film Back to the Future.
Unit conversion:
1.21GW (gigawatts)
1.21GW x 109W (watts)
Comparisons as power:
~~ ( 0.1 ~~ 1/10 ) x power of space shuttle at launch (~~ 1.2x10^10 W )
