The Matrix! (Score 1)

Loved the movie, but ended up coming out of it with a real bad taste in my mouth - the robots had to spend all that energy keeping people alive and running the Matrix so they could generate their energy from the heat that human bodies generate? I was (and am still) furious about it. Even though the laws of thermodynamics aren't my favourite laws of physics (things would be so much easier without them), they are still laws of physics. You can't put energy into a closed system and expect more energy out than you put in!

Arg.

They could have done some much better pseudoscience (eg. they needed the human mind's fuzzy logic processing power, and the matrix has problems encoded into it for people to solve), but no. They had to use the human body's heat output.
