Hi,
If Bok is Phil, the admin of this site, he allready has one code for just allowing this action to happen in his forum, so he is out of competition, because he will get other things to do (ranking the best ideas). So you can declare one idea to someone else.
Asteroids@home + Trajectory@home is only one idea in my opinion, because this is essential to know, where a deflected spacerock is heading after the trajectory change. I wouldn'tbe wise to play with "god's rules" without knowing, if this spacerock will hit earth the next orbit revolution.
I can think of a given scenario, like Apophis hitting earth and then trying to hit him with different kind of lasers on different hit-surface-areas, or by gravity tracktor pulling by a space-ship with different counter-masses and analyzing where the comet/asteroid will head afterwards.
This is tricky, because how should a DC project space debris? NORAD does this, but they are reallllly god supported and they are only able to track junk the size of a 2€ coin. And can you explain the garbage collection to me how to use DC?
I really like your distributed idea system . hopfeully I don't have to rank your idea in case there will be more then 10 posted idea
