RE:Let's start imagining a different scenario >>>Reuters has it @ 1 centavos on 3-21-2021...
the carry trade, interest - is a few pennies short of [-]900%..
the other item that lingers is the Vent Fans ! is that mine pulling water ?
think HVAC... i.e. large medical center in chicago - lots of lake humidity in the summer.. --> @ nite the center will Chill Air on the Top Floors.. and then dump (air) in the early am to drop temp..
if there is a balast shaft midpoint.. then they may be starting a new tunnel - headed nor to alaska..
if it's @ the end of the current digg.. then they may hav a water problem.. or the hygrometer of the wet and dry bulb are out of saftey standards
