That sounds really neat!

The environmental equations I have trouble with tend to be the ones that don't lend themselves to being measured in a single unit. Is it better to use cloth kitchen towels (which use cotton fibers, require heat and water and soap to be expended in washing, and can transmit food-borne illnesses) or paper towels (which use trees, are processed with chemicals, and go into landfills)? That's not just about energy; it's about waste management and resource usage and health. I haven't yet heard of anyone figuring out a good general way to address the more complex situations that day-to-day environmentalists face.
