Ok, this is out of left field but here goes. A solution, in the future, for storing Earth bound reactors nuclear waste, maybe store it on an asteroid, the moon or a space barge. You could eventually launch the space barge toward the sun. You could do the same thing with an asteroid but it would take alot more to change it's course. You could also store nuclear waste on the moon, but I don't want the moon to be a dumping ground. Better to keep the moon for colonization.
