I know you are in competition with Corporal's Corner, BUT I know you are not in competition with Corporal's Corner. I hope that makes sense. You both teach, but you both teach so diametrically different. You and CC are both great. Thank you. P.S., I certainly have time to learn from each of you!
Love your videos, but i gotta kind of disagree with you on windblocks, as an ex military survival instructor, we used to teach that if possible , while in mountainous terrain, find an area with large boulders too set up a camp fire, that blocks the wind, but the rocks also absorb heat and will radiate the heat back out even after the fire has gone out (as long as the fire has burned for a while), but finding a natural rockfall that is safe enough, or a small depression in the side of a cliff, just have too be careful that while the rocks are absorbing heat they are not going too fall from fracturing due too expansion from the heat, so only certain rocky terrain/boulders, but it works
About that heat reflectors, you were mixing up two different heat transfer mechanisms there, Dan. Namely convection, which is through movement of warm air, which does indeed get blown away by the wind, and radiation. Radiation you can reflect, not very well with a stone or wood, but partially. A mylar blanket is great for this, see Far North Bushcraft and Survivals videos for this.
My backyard fire ring is a semi circle made of bricks. The smoke hugs the wall and doesn't chase me. My clothes don't even smell like smoke.
A panel creates a low pressure zone, which will cause the fire to "point" at the wall. Same phenomena responsible for smoke following you around a campfire. Can easily simulate this yourself by blowing on a lighter from behind a piece of paper--the flame counterintuitively moves toward the paper
A space blanket or even a black plastic garbage bag will reflect infrared. If you put a layer of that over the heat reflector, it will work pretty well. I used to use a space blanket on a stick frame about 2.5 ft high as a reflector when I camped. I found that putting it at least 4 ft from the fire would keep it from melting. I would set it up to reflect into my lean-to with the prevailing wind hitting the back of the shelter. It is fairly easy to make it a shallow chevron shape so that it will kind of focus the heat where you want it. That worked really well; even in late winter. It made a good difference to how comfortable it was to sit or cook there when it rained or snowed.
Lots and lots of experts on here , don't know why they bother watching anyone else's videos ! All they do is make attempts at correcting Dans or others techniques ! If you're so good .. start your own channel instead of trying to one up the WELL established channel ! Maybe you will get a spot with Canterbury ! Guarentee you there is very little you will contribute to these guys experience !
The survival industry is a gimmick. Bush crafting isn’t survival it’s Boy scouting, enjoying the outdoors.. Survival is an emergency.
All the times I’ve been camping, I’ve never come across a perfectly cut square rock slab like that!
The "reflector panel, wind shield, fill-in-the-blank-with-your-favorite-name-for-it, is indeed a useful tool if you are gonna be onsite for at least 3 days. It does reflect heat, but not enough to make a difference. ( Use a thermal imaging scope and see ), it might deflect a bit of wind, but you addressed that well enough already - but what it DOES do is direct the heat and smoke toward the surface of your panel/shield (
There is no one best way to do anything. My number one rule for anything outdoors is assessment.
My scouts will use a military casualty blanket(tarp grade space blanket w/ grommets) for fire reflectors. They build the frame and mount it shiny side to the fire. Works well and added to a Kochanski type super shelter..they stay toasty.
Some years back, my boys and I were in some colder, wetter conditions than we expected in AZ high country and despite our best efforts, we just couldn't get a fire hot enough to burn well...and rather than retreating to our tents, we grabbed some flashlights and went looking for better wood. Led to an awesome discovery- someone had left behind some scrap plywood pieces that we set up as break/reflectors and it concentrated so much heat, we had a roaring hot fire in no time. So from then on, I carry a sheet of plywood cut up into roughly 2' x 2' sections and we employ that as a starter method in cold weather- never fails, and it gets things hot in a hurry. Makes the sitting by the fire so much more enjoyable!
Well if you want to set up a heat reflector you need a material that reflects infrared radiation. So you need something shiny or white. A light yellow or light gray color can work too. So if you find a painted plywood board in those colors for an example it can work as a heat reflector. Best option is if you have one of those silvery emergency blankets with you to set up around the fire.
My 2 pence is, living on the moors all the wood is wet and damp, we were camping in winter and the wood was frozen, it was -8C and we really needed dry wood to burn so the heat reflector acted as a wood dryer of sorts, we would take the logs out of the slots to burn while putting frozen wood back into it to dry it some, this worked and we had a comfortable night ever though it was a faff to do.
#1 way to spot a tourist camp site here is the stone fire ring… cute… but not going to actually stop the fire. Safer to clear the entire area around the fire of leaves and debris that could catch.
Most of the heat that you get from a camp fire is in the form of radiant heat. The properties of objects determine how good they are at adsorbing or reflecting that radiant heat. Good reflectors like mirrors and shiny metal sheets are rare in the bush. Light colors reflect more heat energy dark colors adsorb more. I grew up in Phoenix AZ. I could walk barefoot on concrete in the summertime but not asphalt. There is a huge difference between them and it is all because of the color. If you use logs for a reflector wall split them and face the light color interior to the fire. Or better yet make it out of light color stone. Putting a reflecting wall behind you instead of on the other side of the fire is effective too. Another thing these reflecting walls do it create a draft that pulls the smoke upward instead of toward your eyes.
Hello from romulus Michigan brother thank you for sharing your knowledge and expertise and for taking us on your adventure through the woods and GOD-BLESS
Good video & tips. I think the thing with walls or anything that blocks the wind is that it prevents dissipation and not so much the reflection thing. I've used simple mylar blankets to trap the air around the 🔥 and it seemed to work pretty well.
Also, bear in mind that CcB is eastern US, It doesn't get dry here but a few weeks a year. Small grass fires are rare and make the local news and will be talked around town for a couple of weeks. This past summer (2023) is the first time I've ever heard of a local government merely asking people to reduce water consumption. This was because we had less than 1/4" (6mm) of rain over the span of a month.
