I looked at this as Senior Thesis project in Engineering College. One of the problems was the so-called Coriolis forces acting on the fluid. These forces would be nil at the equator and on the Poles.
Does the author know of the guy who tried this in a mine shaft in So. America?

About once a month at Sigma Xi headquarters, we liven up the lunch hour with an American Scientist Pizza Lunch talk. In these informal lectures, scientists describe new research to nonscientists. The series is light on jargon but heavy on solid science. Each Pizza Lunch offers an in-depth look at its subject, whether it's bedbugs or the smart grid.

JSTOR, the online academic archive, now contains complete back issues of American Scientist from its inception in 1913 (as Sigma Xi Quarterly) through 2005.
The table of contents for each issue is freely available to all users; those with institutional access can read each complete issue.
