hello Blackie- Good points here regarding use of available tarps. Ive learned over the years that if I only have one tarp, I find the happy medium between me and the tarp. In other words- in a hot environment, the closer the tarp is to you, the more hot it will be. This being said- maintaining that space between you and the tarp is critical in how well you will stay cooler. Thanks for another video and when you and Bear going to do another video? Take Care-
Thank you. Interesting, someone has intelligently explained how the principles of house construction and particularly the eaves and attic spaces relate to outdoor cloth shelters. Your integration of the thermodynamics allows the viewer to expand on the concepts. You and the guys at This Old House truly complement each other. The millenia of human habitations began with simple shelters made from locally sourced materials oriented to fit the geography and its weather. People with better shelters lived better and their social group had better opportunities to thrive. We all decend from successful hunter gatherers. Your lessons honor our collective legacies.
Not quite. You don't have the Venturi effect until you have a narrowing of the flow path in a channel. Then the pressure is higher where the flowing air is backed up, and the pressure is less where the pathway is narrow and there are fewer flowing air molecules. Blackie is talking about convection, where hot air rises. He also talks about radiation, where a hot object shines infrared heat radiation onto you from above.
Blackie, Great Video and Outstanding Information. Thanks for sharing. I Greatly Appreciate All your Hard work and Sharing Your Wisdom and Experience and Knowledge Thanks Again. You Are The Master Woodsman and Bushcrafter. Tim L. U.S. Army Vet.
I like to hike during day for +-6 months, and at night for another +-6 months. The night protects me from heat. At least in Poland. Much less water needed
If you have and can risk using a gold-foil upper tarp, that reflects infrared better than anything. Even a white tarp will reflect a lot of the heat and light if you don't have to worry about giving away your position.
Excellent ! Creating an airspace between two tarps is exactly the same as we were taught in the service for desert/arrid deployment ... dig down about 2-3 ft., build a 3 side sand wall appx 6" to a foot high. Lay tarp #1across and secure. Build a 2 side 6-8" "wall", and stretch tarp #2 across it, and secure it. You have the air space to deflect/vent the radiant heat. Your shelter is 15-25 degrees cooler
Pretty work Blackie, Thanks for going to the trouble to video and presenting an organized lesson with demonstration and explanation of why and what. PS. If back in the day, my school teachers had been as organized in their lesson plan as you are, I would have paid better attention and retained more. Thanks again for another great lesson.
I’ve seen times when the heat and humidity were so high that the sweat on my skin was so thick I could scrape it off with my knife. That’s a dangerous combination for sure.
A quick way to cool off is put a damp gaiters or bandanna on the top of your head. It absorbs the heat from your body quickly, and will give you some relief from the heat. It does the opposite off what a hat does in the winter time.
Blackie .. would a one of the reflective blankets turned shiny side up as your bottom tarp help even more with the cooling effect .? Question 2. The sun lense you gave away at your gathering .. where can I get one of them .. ?
You don’t need to wet your clothes, I just wet my neck gaiter, ring it out and pull it over your head. By cooling your head , you will feel a lot cooler. That gaiter will absorb your heat from your head. It will also dry it. Lol.
thanks for watching
Good video Blackie , thanks for sharing , God bless !
Thanks from Savannah GA
HOT is the word here this time of year.
Blackie.....genius! Thank you for the great explanation! Stay cool and take care...Robin
Useful information, thank for detailers o what it happening and why.
Reilly good video.
Really helpful to understand the differences of heat transfer and how to keep yourself cool under those hot situations
Thanks for the great explanation Blackie! Such a wealth of knowledge!!!!
Always great information, thanks again.
Blackie, thank you for the content please keep it coming.
Great video! Thank you for sharing your vast knowledge. Looking forward to the next video.
thank you
I'll have to give this a try because it's gonna be getting ridiculously hot here very soon in Tennessee.
Appreciate it 👍👍
Great information, true about shade, unfortunately we camp mostly in pine forest very little hardwoods
Excellent tip thank you
It does help a lot. That's for video.
Great information
Great, as usual
I have had this on my mind thanks Blackie

Great video and Lesson, Blackie. I thought shade was shade. 👍😓
Great Ideas!
Fantastic explanation!

Excellent presentation and explanation
Thanks for the info
This is a great technique. It goes back way before WWI. Probably predates ancient Egypt.
Pretty sure that air flow you were talking about is known as the Venturi Effect. I like it !

Then the pressure is higher where the flowing air is backed up, and the pressure is less where the pathway is narrow and there are fewer flowing air molecules.

Thanks Blackie
glad to do it

I also place wet clothing on the top of the tarp to dry and remove some of the heat.
Thank you Blackie, I appreciate your double tarp method. I will take any break from the heat I can get.

Great set up, reminds me of the directions for downed aircraft in WW2 with parachutes. It's a reverse of the winter double walled tent.
Thank you. Must get real hot in the Deep South. 🇺🇸 🇳🇿

Well I guess you kinda already answered that question .. I had to pause for a little while for company

That works for moderate heat but when it gets 110-120 in the shade you will be toast if all you do is rely on a wet scarf.
For optimal results you need some air flow/ movement to create condensational cooling
People with breathing problems doesn't need to be under nor in a pine forest.
Not when the pollen is active. I have breathing problems from the Covid but when it's dormant I don't have any major issues
Thanks!
