    Polystrate fossils are a key indicator of this being true. Maybe not those overlapping one-or-two layers, but the fossilized trees that cut through many layers, as that logically sets the date of those layers to be the same (geologically speaking; before the tree can rot). Although I don’t know this to be true, I would not be surprised to find an unbroken chain of fossilized trues from the top of the geologic column right to the bottom, which would prove this idea writ large…



  • Thanks for the thoughtful reply. I think the “shipyard guys” are trying to tackle 1 & 2 (as well as lessening the concrete on #3). Though, I would be surprised if your numbers for #3 are right… it seems odd to me that a ton of concrete would produce about a ton of CO2 (but maybe it’s just one of those counter-intuitive things!). Thorium is interesting for #3/mining because it is produced (unrefined) by rare-earth mines (unlike special-purpose uranium mines). As for #4, I would argue simply that it is “better than coal” insomuch as we have neither found a good way of dealing with the fly-ash and soot-ash from coal power plants (yet they operate); i.e. ash ponds & coal ash impoundments.
