As you've probably heard, the first privately funded spacecraft made it into space today. This is good news for people such as Lance Bass- it gives them one more potential avenue for getting to Mars. Did you know that if Lance were to go to Mars, he would produce roughly a ton of poo? It's true, assuming a trip of 2 years. That's a lot of poo, even if it is catchy, repetitive, appealing-to-the-general-public poo. What to do with all that poo? Don't forget that Lance is likely to have some co-astronauts, who will produce a similar amount of poo, though I think theirs would be less prone to 5-point harmony.
One elegant solution is to harness the intrinsic power of poo (what have I been telling you all this time?), recycling it for drinking water, food, and even, possibly, fuel. There is a bacteria called Geobacter that can pull the double duty of breaking down organic matter and generating electricity.
