No, really. I'm serious.

2. Sorry. I lent mine to my Dad and he left it in 1932.

6. Just go to home depot, they have everything you need there to make your own.

7. Yes, I have several. But I must know WHY you wish to utilize one.

:sigh:...nevermind.

9. I have a time machine, but I don't like to use it because it makes my electric bills sky high!

Let us see: a human weighs 60kg, 1 gram of matter has a rest mass of 90 terajoules. (1 terrajoule = 1,000,000,000,000 Joules)

1 Watt = 1 Joule per second

So, it go just 1 second back in time, it would take 60,000,000,000,000 (with 13 zeros, or 6 x 10^13) kilowatts.

Electricity costs 0.04 euros per kilowatt. That means 2,400,000,000,000 euros!

Here is how this works. The first second worth of energy is enough energy to travel infinitely fast in space (not back in time) and would result slowing your reference frame of time by half. The second worth of energy would begin to send you back in time, but only at the rate you are currently moving forward! That is to say that if you are 20 years old, it will take 20 years of time travel to go back before your birth.
