>>a bit of nuke power that never came from the sun
Well, actually all of the elements that feed that power originally did come from either this sun or the one before it, as massive atoms need a star to nova to create them.
Our little sun may have a bit of heavy elements --well make that ionized nuclei in the plasma-- but but like our heavy stuff they all came in from the neighbors. Of course, way back when the package arrived the earth and all the other planets were just a big 'sun ring' so in that sense I guess everyone's right but me ]-(
