What a wonderful idea! Why not try using natural convection currents to save on fan electricity, the top edge would be hottest especially due to the angle the panel is on. I bet the air is much hotter on the outside edge too, how much heat is being wasted being reemitted? You can siphon /circulate the hottest air from the outside panel too. Is there such thing as a one way greenhouse coating for the film to block thermal heat from escaping but allow it to pass in from sunlight? would a concave shape minimise reflections of the sunlight? Would increasing surface area of your corrugated sheet on the inside AKA a heatsink allow better transfer of heat?

I love that even though the propane + oxygen + variable flow rate didn't heat the steel as you had thought, you kept all of this footage here! I love that you show the whole scientific process.

When i was inte special forces in Sweden in the 80's wax was the only option. Other waterproof materials was to noise, and t

Hi, any tips and tricks for a decent waterproof stuff for my shed lol I want to keep it the original wood colour that I bought it like, and did buy wood preserver that was supposed to be waterproof but it's still seeps through the side panels

would it be possible to maximize the surafce area without covrring a large portion of the sun. like if you want to cool more than the space you have. i have been thinking a sort of a flower design. if the infrared heat that is supposed to go directly into the sky instead hits another surface of the same paint than would it still work. i think there would be some loss but not that much compared to the convinience of having the thing be compact. also what if you sandwich the paint between two layers of that plastic layer that is used to cover the paint from the outside air convecting the paints surface too much. if you did that eould you be getting twice the surface area compared to the normal setup? sorta like a lotus plant design it would look pretty awesome to. you could fit a lot of surface area if the efficie cy drop is not that much. i think the idea is good enough but the problem would be making the petals leaves what ever those plants have . you could make it a strict box design but that will have stiff right angles which might not work as well. this feels like something you might have already considered. which makes me think it might not work. so the two maib questions are how much would the efficiency be worse. i read somwehre dont remember where that lets say you have the paint on the ground directly facing the sky the paint only emits the infrared in a cone shape from the paints surface. and they get worse at sending it at steeper and steeper angles. so it would have to be sorta a lotus look a like. also would sandwiching the paint between two layers of plastic would that really double the surface area even if its less effiicient since the paint would have to the stading up right ? origami lotus. i think this could work. i just need to know a little what you think of it. i have watched this video too many times and cant get any info on any of these questions i guess the only way is to just make the stuff.

I enjoyed the entire vid good job man and you taught me something that i will be using in the near future to replace my boat tarp. Thank you.

whoa!!

aka Never use your wife's sewing iron *L* I liiked the whole thing! wow...my head is overloaded with ideas! thanks!

I like to use your wax mix and method of applying except I like to do it on a hot day. Leave item outside and apply when it’s warm.

You would have gotten a much more uniformed and less distorted swing by using a single per pendulum instead of it being doubled.

Hello! I don't know if this will get seen, but when I tried, the powder flashed a bit too quick. I mixed the 4/2/1 weight ratio of potassium nitrate/sulfur/lampblack, but the powder in the sparker burns quite quickly, almost as if it was black powder ratios. If whats left falls off, it does turn molten and emit sparks, but the violent start sometimes knocks off a bit of the powder. Any suggestions to make the mixture less flammable? Also! the spark pattern does not follow the traditional 3 stages. ALSOALSO, the powder is definitely grayer than what you have

It's cool, I might even use this method. My biggest concern it obviously flaking of the wax. However, my other concern would be how much weight this might add to the clothes or tarp... 🤔 maybe I missed it in the video, but any thoughts?

All good! Thanks

I really liked this. What is Gortex

Great VoD! How would be the process of washing this wax coated jacket though?

Us residents only!

What happens if you leave it molten and paint it on with a paintbrush?

Another outstanding video Ben! While watching, I started thinking about other ways to evenly apply the wax mixture and my first thought was to somehow spray it on while the wax was still a liquid. I did a quick Google search and found a few spray guns designed specifically for spraying hot wax. So now I'm pondering different ideas for a DIY version....Maybe modifying a cheap sandblaster kit since the nozzle and tank are usually metal, meaning more options for heating the wax and for cleanup. Or maybe using the nozzle + heating element from a hot glue gun to help ensure the wax is sprayed out in liquid form. I would love some feedback/suggestions from yourself or others.

Nice one

What is this mineral oil? I am not sure what would be the equivalent in Europe, but there is nothing sold directly under that name. In UK it should be paraffinum liquidum, right?

Brilliant 😊

"unauthorized" if I own it it's authorized.

This could be a great waterproofing solution for canvas tote bags here in Seattle.

How about adding iron oxide to your recipe to add color snd filling in pores in cloth

How can you add UV protection?

dangerous. got it. brb going to try this at home.

Two questions I have after watching this: What is your process for filtering larger batches? Have you tried applying the pigment similar to how you would a plaster?

Absolutly amazing. I´ve looking for just that. great i found it on youtube. so many thanks from germany !

You should combine this water proof and the heat reflective paint. Maybe it will work. Gonna try this also on a cloth to be used as tarp.

Next he should use it on a Sterling motor.

I am going to make your paint. I am using it for a novel atmospheric water generation system which might or might not work. thanks for all the videos

Even after 6 years that's so cool!

I have some rhodium that needs melting so I can sell. You think this is a reasonable way to try. I'm not in financial position to buy an oxyacetylene setup

I would be interested in mixing a fire retardant

So, the wax that you are using is the same wax that's used for candle making, right?

I came here after looking up your previous waterproofing video for a friend. I was very excited to see an update! I'll probably be using this technique in the near future on some of my jeans, as I've put straight wax on them in the past but as you demonstrated you really can't get an effective amount of 100% wax on fabric without reducing the flexibility (definitely a problem when waxing pants!!!)

What I tell my girlfriend 13:50

Great video. Thanks for the explanation..

Wait ... how do you wash these clothes 🤔

I would think that using an outer shell that you water proofed with a inner liner shirt to get the same waterproof jacket that is also insulated to keep you warm. I hope to try this by next fall 2024. Thanks for a great video.

Other than environmental issues, does this function better than the naptha/silicon sealer?

Have you ever been told that you look like Ted Cruz?

Wouldn't bee's wax work better? If I remember right, it's more flexible and doesn't crumble like paraffin.

Instead of an outside flapper valve try an o ring inside the barrel. The force of the vacuum will cause your projectile to double as the valve and instead of pulling the piston out at the breach drill some vent holes just forward of that point. Now I have to try it

I'd be interested in knowing the weight of your jacket before and after the treatment.👍

I love when somebody shows me handy tricks that my grandparents might have used. I especially appreciated the “button” trick, and the knot tutorial.

Not only free of salt, but also distilled) So any bad water might be used)

I have another question. Does this wax-oil mix already have a UV-resistant property for fabric? Or should I add something to it when it's molten? And if you answer yes to the latter, what should I add to the mix?

You're really doing a public service with this🔥🔥

Very informative. Thanks for sharing. I subscribed.
