Let's face it: Everyone doesn't want the planet to heat up like a warmed-over burrito and we'd all love to do something about global warming, but it's just that it's so much fun and convenient to pollute the air with our cars, power plants and cigarettes.

That's the deadlock that mankind is trying to break. We all want a good Earth and at the same time we don't want to stop living large, so the X Prize organization is organizing a contest in hopes of finding the most convenient solution possible.

With million at stake, mechanics and automotive engineers from around the world will try to come up with a clean and fuel efficient car that can save the world. The ultimate goal? Make the four-wheeler run a hundred miles per gallon.

These are the rules of the contest:

• Be simple to understand and easy to communicate
• Benefit the world - this is a global challenge
• Result in real cars available for purchase, not concept cars
• Remain independent, fair, non-partisan, and technology-neutral
• Provide clear technical boundaries (i.e., for fuel-efficiency, emissions, safety, manufacturability, performance, capacity, etc.)
• Offer a "level playing field" that attracts both existing automobile manufacturers and newcomers
• Attract a balanced array of private investment, donors, sponsors, and partners to help competitors succeed (e.g., manufacturing assistance, testing resources, etc.)
• Make heroes out of the competitors and winner(s) through unprecedented exposure, media coverage and a significant cash award.
