       | perpetual motion is kind of guaranteed by quantum mechanics

       | Isn't perpetual motion the basis of the whole universe?

       | I mean, it hasn't stopped yet, right? And it technically does all
       | the work we do?

       | indication that you can somehow extract anything from this.

         | Pulsing is just standing still, but with a bit extra flair.
