A bit off topic from the above post, but hey, it’s not as if I’ve got any statement saying that comments are supposed to be in response to the post, so until/unless I explicitly state that then I’ll respond in kind.
That being said, our comments here may disappear from this post once this blog switches over to its new blogging platform in a few days as I’ll also be using a new commenting platform. On top of that, the EROEI Primer that you quoted from will not be re-appearing on the new blog, although it will be completely re-written and posted at a later time. So supposing that I manually migrate comments over or something I may not migrate over this discussion.
Anyhow, about your comment.
To be honest I’m not completely sure what you’re saying there, as I don’t quite see what recognizing that the energy on this planet came from the sun (and other stars, which came from…) has to do with the amount of microorganisms in a gram of soil. Nor am I even sure what you mean by needing to state “the boundaries within” when talking about closed systems. The universe… is finite?<!—25th October 2017 9:56am->
