Ok well. I figure we need 2 lists going... I for the actual flux capacitor, and the second for a separate bank account to fund the power required.
If it takes 1.21 gigawatts to power it up, and at roughly 10 cents per kilowatt hour, that is roughly $121,000USD an hour. And if we are going to go up to 88miles per hour and then stop the power sucking, then it should only cost us a fraction of that every use. (I wonder if they make a deep cycle discharge plutonium battery???)
We probably don't want to vary too much from the original, or else fear being stuck in a void of all time, so we need a DeLorean too. There's a third list! It can do 0-60 in 10.5 seconds so like 15 seconds to do 88. Therfore 0.004167 hours.
That means every time we run the thing, 1 way, it will cost us about $504USD.
So to sum it up:
Flux Capacitor: Maybe we can make some with bubble gum, LED's, and duct tape? So like, $20USD
Power: $1008USD Round Trip to anywhere in time.
DeLorean: $15,500USD (http://www.chooseyouritem.com/autos/...00/141385.html)
