<p>Poo is mostly water and will volitize relatively soon. Anything not volitile will become extreamely light weightn when it cooks in the sun.</p>

I liked the poo cannon too but I just realized that since it would take more than one poo to eject each piece of space junk, you would get rid of the metal junk but would be left with a lot more pieces of frozen poo flying around, a potentially more dangerous situation, right?.... <br>

I love the idea of trash cannons!<br>
<br>
And do check on PsyTek's links to the USAF Space Fence.<br>
One of the main purposes for the Maui astro observatories and supercomputing center is space debris tracking.<br>
They have some science-y scopes up there, but original DARPA funding was for debris tracking.<br>
One project they have is a laser satellite tracker/measurement system where they bounce a laser off sats to get high res distance measurements.<br>
hmm, maybe I can interest some of their techs in our program.<br>
