Conservation of Energy

Wanna go to the market with me? We need a few things.
Nah, I'm working on a new project, and I may be close to a breakthrough.
What project? You've been lying on the damn couch all day!
That's the point. It's all about conservation of energy. A very important principle these days.
What about me? I'd like to conserve some energy.
Sorry, you're not part of the algorithm.
How do I get to be a part?
Get me some ice cream while you're out and I'll see what I can do.
