I know when I put my whirlybirds on the house, they did pretty much nothing until I put some eaves vents on the shady side of the house and then the temperature differential went from 5 deg lower than ambient to 15 degrees.
Of course, this may not be needed if there is already good airflow from under or through floorboards etc, but I thought I might mention it anyway.
By the way, how do you keep warm if there is no slit and half the pod is open to the sky? Are you able to heat inside (bar heater etc) without causing too many thermal currents?
Cheers

There's good ventilation between the dome and the walls in the POD
.
Warmth is acquaired the same way as out in the field
... layers of clothing, freezer suits, etc. Because there is no separate warm room, heating is not on. Too many thermal currents. Having said that, it is naturally far warmer in the POD than without. Radiation loss is less than 50%, there is exscellent shielding from the wind etc. I haven't used a dew shield or a dew heater on full power since I've been in the POD.
