Zhang, Holden (Hong-Quan)
Holden (Hong-Quan) Zhang has a PhD in Fluid Mechanics and joined the University of Tulsa in 1998. In 2019, he published Revive Eden: Green Sahara Now.  which investigates the disappearance of the Green Sahara and the possibility of reversing that event, not just in the Sahara, but in other desert regions also. In chapter nine of the 2nd edition of his book, he outlines his Atlantis theory.
Additionally, he recently published a YouTube video(a), in which he places Atlantis in what are now the chotts of Tunisia and Algeria. Although Zhang endeavours to present this as a new idea, it is not. In fact, it has been around for about a century, with continuous support ever since.
Zhang claims that his theory matches Plato’s description of Atlantis 100%! Wrong again; Plato clearly states twice (Tim.25a-b & Crit.114c) that Atlantean territory included some of North Africa along with part of southern Italy as well as a number of the islands in the Central Mediterranean region. So, in my opinion, Zhang is only partly correct regarding the extent of Atlantean territory. Nevertheless, I think he has made a useful contribution to the Atlantis debate.
A full written outline of Zhang’s theory is also available online(b).
I was amused to read in the same 2021 paper that Zhang wrote as follows about Aristotle’s description of the Atlantic Sea,
“This is not a description of the Atlantic that we know, which is not shallow, calm or lying in a hollow and which he refers to as a ‘sea,’ not an ‘ocean’.”
In 2018, on page 158 of Joining the Dots, I wrote;
“This is not a description of the Atlantic that we know, which is neither shallow, calm nor lying in a hollow and which Aristotle also refers to as a ‘sea’ not an ‘ocean’.”!!!!!
A further paper by Zhang was published in 2022 in support of his theories. This time he used details from ancient Egyptian Pyramid Texts.(c) >Zhang offers a video to accompany the paper(d).<
