Solar Stirling is kind of cute, what is the ErOEi for those? Most of the
other solar things have very very long return tails; lots of energy to
make and install solar cells and not a lot of return; Solar heating
seems to have been a much better bang-for-the-buck.

Well, really, when you get right down to it, solar stirling *is* a kind of
solar heating.

I haven't found actual eroei but I have found some efficiency stats.
20-30% for solar stirling (as opposed to, what, 12% for pv?).
