Reflector Dome Tent

Parabolic Dome Tent Focuses Heat On Single Hot Spot

When camping in extreme cold conditions, it's important to keep warm - especially to keep the head warm. While the rest of the body can be covered with clothing and sleeping bag for warmth, the face typically has to be kept exposed and uncovered. Covering the face only leads to CO2 and moisture buildup from breath.

We can have a tent with a parabolic dome shape which could focus all infrared waves onto a single spot at the interior. That spot would be where the occupant's face/head would be.

Perhaps a small safe heat source could be hung just below the central apex of that parabolic dome. Maybe it would be a small candle or small oil lamp (see links). A small central aperture at the central apex of the dome would allow rising smoke to escape. But the bulk of the heat radiating from the heat source would be caught by the parabolic dome and reflected/refocused onto our thermal focal point, where the occupant's face would be. This would allow the occupant to sleep comfortably without catching a cold.

       So you'll notice I linked to small lamp-style burning heat sources. That's because burning heat sources tend to be the most energy-dense, and we'd like our heat source to last as long as possible - at least through the duration of the night. I picked small oil lamps because they're more portable. If you were camped in a tent in the Scottish highlands or in high mountains, you probably won't find much more than scrubgrass in the upper reaches, and won't have lumber conveniently available to burn.
