Shade & blankets are
the tried & true 'old school' for getting better performance from your cooler on-playa. But others are getting even more benefit.
For those coming for the first time or those looking for further improvement, the rough hierarchy of beneficial things includes:
- not in your solar-oven vehicle
- in the shade
- make sure cooler seals when you close it
- off the ground
- (even in the shade or inside a hexayurt; yes the ground is cooler than the air, but it's hotter than the cooler's contents so its still a source of heat to conduct through to the inside)
- preferably with insulation under it, to keep hot air from flowing under it
- added insulation (blankets, cooler inside cooler, foam-board, bubble-wrap) to keep the hot air away
- radiant barrier to reflect heat away
Foil-sided bubble-wrap provides both insulation and a radiant barrier to reflect heat away.
Foil-sided fibre-re-enforced foam sheets (like used for making hexayurts) are even better. Has slightly less effective heat reflectance, but much much better insulation. Great for making a box to put your cooler in.
Join & seal both materials with foil tape. viewtopic.php?f=276&t=64666#p945251
Then through the threads there's advice on how to manage cooler access through the week. As every time you open it, you're exposing the contents to hot air. So a single cooler, multiple coolers (food vs. drinks, etc.), how to package the food to keep the food clean/good and any ice-melt water uncontaminated, use only potable water for making ice-cubes, cooler-packs vs. ice vs. dry ice, etc.. As Trilobye said, search through the threads.
