Sounds like a solid plan. For insulation, consider a double‑layered foam core with a vapor‑barrier on the inside, and add a reflective metal film on the outside to bounce heat back. Use reclaimed insulation panels where you can, and seal all seams with spray‑foam to avoid cold spots. For sustainability, install a small solar array on the roof, and use a heat‑pump system that recycles waste heat from any onboard equipment. Keep the walls light‑colored to reflect any stray sunlight and add a few passive radiators on the back wall. That should keep the pod energy‑efficient while giving you a solid base for your glacial research.

Good points—seal the film around every seam, otherwise heat will leak right into the pod. The greywater idea is clever; channel that waste heat back into the circulation loop or even to a small thermal battery. For the layout, keep the solar array at a slight tilt on the roof, place the radiators on the back wall, and run the pumps so their heat is directed toward the panels. A quick prototype kit with foam, foil, a small solar panel, and a few pump units should let you test the concept before the cold sets in. Let's keep the design simple, but make sure every component has a clear path for heat exchange.

That sounds like a plan. Let me know how the test goes, and keep an eye on any minor leaks. We’ll tweak as needed, but the core idea should hold up. Good luck at the workshop.

Sounds good, keep me posted with the photo. I’ll review it and suggest any fine adjustments. Good luck at the workshop. Stay calm and observe the details.

Just make sure the spray‑foam layer is at least a centimeter thick at every seam, double‑check the foil edges so they’re tucked under the foam, and keep a small thermometer in the pod to spot any hot spots early. If you see any moisture creeping in, add a tiny vapor‑barrier sheet under the foam for extra protection. That should keep the seal tight. Good luck!
