EEEEEK! I'll remember this! Based on other warnings in other threads relative to oxygen depletion, carbon monoxide, etc, if I ever do build a tear drop, it will have permanent open vents.
I've had a fascination with "dry ice" for a long time. When living in SW Colorado, I often hiked in an area called Sand Canyon where there was a riser for a CO2 wellhead. It was covered in thick ice all year long, even in the most blistering days of summer. Here's a bit of information about this CO2 deposit:
The McElmo Dome is one of the largest known pure CO2 source fields in the world, with over 20 trillion cubic feet of CO2 in place. Kinder Morgan CO2 is capable of producing and transporting approximately 1.5 billion cubic feet per day of CO2, making us the largest transporter of CO2 in North America.
On the extremely off chance any of you are familiar with this area, it's west of Cortez, Colorado, on the McElmo Canyon Road, near Canyons of the Ancients National Monument.
Cortez is better known as the place you stay if you are getting ready to drive up to Mesa Verde National Park.
