 how many exo-system Plutos could one expect to be out there?
 I'd say may be debris fields of Plutos for harvesting
 are more realistic?

 We
 quite literally have no idea of what’s out there between
 the stars.

 We don’t have
 the ability to see things that small, dark and cold; they
 could be common, they could be incredibly rare. We won’t
 know until we can look.

 Heck, look at how much we’ve learned about
 Pluto in the last few months. I guaran-damn-tee you that if
 you suggested last year that we would find water icebergs
 ‘floating’ on a solid nitrogen ‘glacier’ people
 would have looked at you like you were crazy.

Yep, I remember, way back when,  I first read about the discovery of Pluto & how it was predicted.
Towards the end of the article it stated that Pluto turned out to be to small to produce the perturbations that predicted it's existence.
First thing I thought was, "Well then, what *was* causing it?"
The article didn't say & over the years the only thing I could get was, "Well, the original calculations must've been in error."!
WOW, talk about a fantastic coincidence!
Who would've ever believed it if it hadn't actually hapened?
