Two things:
- We could shoot negative and positive charged particles so that the total
beam will be neutral and thus not fade away completely.
- Or we could not use particles but instead EM-radiation (eg. a MASER)

I've an idea too, lets hybernize this discussion and defreeze it after a
century. No, without irony, a while ago I suggested something similar, but
the problem is that we cannot predict AT ALL what would be possible then, so
get back to Earth (figuratively) and try to use what we have.

I don't think it will happen. Yeah ofcourse, billions will die (not just
because of old age) but thousands will survive (probably the ones with the
most money and the smartest brains)

Maybe Europe will take over after becoming united.
