    Just a few pointers:
    1. The sand is not a heater--it is a heat sink. The 'heater' design in the video is actually not a very good design at all.
    2. The combustion of the wax & vegetable shortening is where the heat is generated. The sand just absorbs the more intense heat from the flame & stores it & then re-radiates it at a slow rate.
    It would be better to suspend the pail of sand above the candle to heat it than the method that was used in the video. You would also not have to buy expensive copper to heat the sand.
    The purpose of a heat sink is to absorb an intense heat source so that it doesn't rise too quickly out of the zone where the heat is needed. For example, if your heat rises quickly to the ceiling in a room, then it takes quite a long time for a candle to heat a room because it can only output so much heat per unit of time.
    By heating the sand, the sand absorbs the heat & re-radiates it more slowly at the level that a person can benefit from that heat because that heat will rise slower than from the flame of the candle. The sand isn't a heater--it is a heat sink that absorbs higher heat intensity & releases it more slowly.
    Also note: There is more energy per $ from paraffin wax than from Crisco Shortening, so it would be better to use multiple candles below the metal bucket that is filled with sand. Here's the data:
    Material MJ/kg) $/kg MJ/$
    Paraffin Wax 47.38 3.86 12.27 (more heat per $)
    Crisco Shortening 38.56 6.02 6.40 (~ half as much heat per $--burn wax instead)

      I watched a vid showing dry coffee grinds soaked in wax.
      The idea is that its a little block of slow burning fuel thats perfect to add to a fire.
      Waterproof too.
      I made a small and big one.
      Not sure how to try it out though.
      I think I might put a wick in, and see if it burns like a candle.
      If its bollox, then at least it might have a nice aroma.
      The Viet cong used a 50 cal casing for light when moving in the tunnels. They stuffed it with cotton wool and soaked it in petrol. Very efficient because its a small flame.
      That lasts a long time, but if youre holding it in front of you it blinds you slightly. But, they just put a finger on the top and its extinguished.

    The total energy (heat) produced is a constant. Heating the sand with copper does not increase the heat produced. It simply elongates the amount of time the heat is distributed.

    • @teardowndan5364
      @teardowndan5364 26 วันที่ผ่านมา +44

      Yup, same energy released to a controlled environment, effectively same effect apart from specific heat from the "thermal battery" delaying things at both ends.
      A thermal battery makes more sense when you have a high-intensity heat source that puts out more heat than you can immediately use and then release it over time later. That is the principle behind earthen fireplaces. Thick walls to store heat while the fire is burning, then release it overnight after the fire is put out so the choke can be closed to avoid drawing cold air in.

      Yes, the heat in the candle only makes so much heat. The heat doesn't get any hotter just because it's surrounded by sand. But I can see how this might be a fair little heater in a car in an emergency situation, because it gives a long burn and will maintain the heat in the sand rather than dissipate as quickly. Keeping one in the trunk of your car if you live in the snowy areas might be a lifesaver if you are stranded in freezing weather.

    You do not want to keep the vegetable shorting in the can it came in. It will eventually catch on fire, because it is not metal. Best to use an old three wick glass candle jar. Line up in a straight row to be under the copper strip using bees wax birthday cake candles. You can use 2 - 3 candles. Also do not use plastic terra cotta color plant feet, use the actual pottery terra cotta plant pot feet. The plastic ones will melt, also will become a fire hazard. Do not use a zinc dip metal pail. Do not use a metal pail with a wood handle. If you use a terra cotta pottery plant pot you risk the heat cracking it. Make sure you have at lease two inches of sand between the bottom of the pail and the copper strip.

      @nessay720 20 วันที่ผ่านมา +47

      @ I have the same can, the trim is metal, but the body of the can is foil, plastic, and paper. Crisco no longer uses all metal cans for their shorting product. The materials that they are using now, does not keep the product fresh for as long as the metal container does. Manufacturers are taking shortcuts and trying to make sure you buy the product more often.

    • @nessay720
      @nessay720 20 วันที่ผ่านมา +31

      Also the plant feet you can tell they are plastic. I have the same ones, I also have the real terra cotta pottery ones. So I can look at it and tell the difference. This ideal will work, but you have to use the right items, keeping safety in mind. There is a video on TH-cam of someone else doing this, he shows you the right way f doing it, with all the safety precautions and measures the amount of heat this ideal can produce. This video has the concepts, but not the precautions. Like not all metal cans are made a like. Lowe’s metal cans are hot dip in zinc and you should not use them for this project because of the fumes they may give off. You’re better off buying a fire place ash can, because although they are normally painted black they are made to hold hot ashes and not give off unwanted fumes.

    Nice construction! Suggestion, put the lid back on the crisco can while you fill the bucket with sand. Then there is less chance of getting the sand into the crisco. Also, I would use two copper bands, perpendicular to each other, which would heat all four sides of the bucket of sand.

    I read an old Popular Mechanics article that showed how to build a heat sink from cinder blocks, filled with sand, built in the crawl space / basement but underneath a wood stove. Ingenious idea in that old book.

    • @justinw1765
      @justinw1765 19 วันที่ผ่านมา +14

      You can use a similar idea for solar heating purposes. Stack up a bunch of cinder blocks filled with sand in an area that gets consistent sun. Paint the outside as dark black as you can. Put some reflectors around it. Wrap or cover it (with a bit of an air gap) in some kind of translucent material (acrylic lets in even more visible light than glass). By the end of the day, that pile will get warm and stay warm for most of the night (to keep it warmer longer at night, put an IR reflector over it after the sun goes down so it won't lose heat to the cold vacuum of space). Then pipe the warm air into whatever area you need warmed.
      In the summer, you can put an ultra white, sky-window IR radiator material over it, and turn it into a system that cools. See Night Hawk In Light's videos about making ultra white, sky window IR radiating materials (one of which is just a specifically sized calcium carbonate).

      No, you'll just heat up a pot and that will need more calories. If the burning flame is inside a structure or home it is 100% output. No waste at all. You cannot do anything to it to give the heat a better effect. All you can do is slow the effect which ultimately makes it less effective. And that's exactly what this thing does.

    Soapstone holds heat probably better than a majority of stones. I notice that the area around soapstone rocks, the snow melts away fast. Especially large soapstone. Be good to use pieces of soapstone in the sand...

    • @justinw1765
      @justinw1765 19 วันที่ผ่านมา +4

      Soapstone is on the expensive side. Meanwhile, soapstone is essentially made up of compressed talc, and powdered talc is relatively inexpensive. It won't be as good, because the material is not compressed and there will be plenty of air pockets within any powder, which reduces the heat capacity.
      The property involved here is called specific heat capacity. Interestingly, water has far higher heat capacity than many other common materials, way more than sand and even way more than soap stone. To put things into perspective, soap stones specific heat capacity is 785.2 J/Kg while water's is 4182 J/Kg. Fully dry sand is around 800, salt is around 880, and aluminum is almost 900. That last one might surprise you. Aluminum's ability to store relatively large amounts of heat though, is offset by its very high thermal conductivity. Aluminum is a great material to use if you want to store up the heat and then release it more quickly. You can help aluminum to store the heat by insulating it well, and then when you need the heat, you remove the insulation. This is helpful if one has cheaper electricity at night or during specific parts of the day, you can run a heater in aluminum during that time and when electricity is more expensive, you turn it off and uninsulate it.

      Why does everyone want to use pain in the rear copper ? putting the candles under the sandpot is much better than some hokus pokus copper strips. There is no better way to exchange the heat from the candle to the sand than to put the candle under it, so the flame from the candle does or almost touches the bottom of your sand pot. This eliminates any hokus pokus copper strips that are hard to come by and always are very expensive and way too complicated to heat a damm pot full of sand. Set the sandpot on some bricks to shim it up to work with your candles. Lastly even one or a few candles stink up the place with soot, in the olden days there was a lot of lungdesease because of candle soot.

      I’ve heard that 100 proof alcohol burns very hot & very clean; also that indoor fireplace fuel burns slower and safely, (lung-wise). If true, could these be an effective, long-storing fuel sources for either the under battery burn version, copper core version, or some combination of both, followed by say, indoor safe fuel candles under sand battery to regulate & slow heat dissipation? When I’ve thought about these designs over the years, cast iron has appealed to me as a vessel both for the sand heat sink and, (in smaller form), to hold liquid fuel, such as alcohol, more safely than cat food or tuna cans. I don’t know if alcohol would react with cast iron to produce additional fumes, but if unseasoned, there wouldn’t be other oil residues, though burning off ahead of time might be good if factory residue might be an issue? Unsure how to research this question, or if it’s just out of my league, but design is fun to ponder… I love the comment section too. Interesting channels with heat sink trials are Riverside Homestead, (crisco candles & firebricks) and Desertsun1, (alcohol with stove pipe as well as copper sand battery trials). Good stuff, (here and there). Thx all for time & thoughtful comment contributions. Such educational dialogue. 👍

    a candle gives off about 100 watts of heat. normally the heated air mostly rises as convective heat and mixes in the air already in the room. in this setup the same 100 watts is used to heat a pail of sand and the 100 watts of heat becomes mostly radiant heat as the same 100 watts of heat radiates in all directions from the metal sides of the bucket. same amount of heat as you get from a normal tealight candle. same 100 watts of heat. this contraption with the enormous fuel supply would just last much longer, but by the time it started to radiate any heat you would have already frozen to death so what would be the point...

      That assumes a perfect conversion of the approximately 80 BTUs of heat to the bucket of sand. That's not nearly going to happen. It's impossible for the copper to absorb all the heat being released by the candle. There will still be plenty of convective heat even before the radiant heat begins. This is, in essence, a less efficient immediate heat source for a longer term one, albeit at lowered but still appreciable efficiency. Never forget the curse of entropy. While perhaps not ideal, if you're already in a situation where this setup would lead to hypothermic death if the crisco candle were to operate at lowered efficiency, then you have a lot more immediate problems. While this isn't an ideal setup and I will agree that it may not be the best idea in many circumstances, you're applying frictionless void logic to it, which is never something that you should apply to a survival situation.

    As much as adding copper strips or tubing will greatly help the transfer of thermal energy to the sand bucket heat sink its never going to put out more than roughly 80 -100 BTU an hour and depending on the temperature differential you are trying to overcome its probably a sad choice in an emergency. Your body produces(looses) around 4x that amount at rest, i.e. you are a better heater than this candle is. At best this is a " better than nothing, warm up my hands" device.

Filled the bowl with sand and buried the candle in the sand. I lit the candle and pushed the 7 into the sand with the short side just touching the copper. I didn't test for hours because soot started dripping down. Not sure if it was the shortening or the taper I put in the crisco. The next test will be with a cooking oil candle that is just a one inch wick threaded through a stainless steel scrubber chunk. The wick is for oil lamps.
    Getting ready to make some forever wick olive oil candles and the person from the video stated that the olive oil doesn't bother his breathing, allergies are great, plus the olive oil burns hotter.

    Despite what a previous commenter ab_ab_c bashed about your design, I think it's brilliant! It's a very cheap and simple design which I like. The commenter is more wrong than right about what he said, especially regarding the sand; it is mostly an insulator here. It is definitely NOT a heat sink. The copper is the star heat sink in this show; it distributes the heat throughout the sand "good enough". This design keeps the heat centralized to the local area excellently and then only slowly dissipates the heat because of the sand. That is what you want in something that has max efficiency in KEEPING a room heated, not how fast you can heat a room. Love it. keep up the good work. Of course this design has inefficiency due to a flame losing a lot of heat to air, but the heat that is not lost and kept in the sand is a fantastic idea. ab_ab_c's alternate suggested idea, I hate to say, is garbage and would not retain any significant amounts of heat compared to your design in the vid because once again, sand is NOT a good heat sink!

    Neat idea, but I'm not really sure what the point of the copper/sand is for actual heating efficiency. If the whole thing is in the area you want to heat, all the heat from the candle/fat burning is already being released into the room. The sand/copper is just being heated by the heat that would've otherwise been used to heat the air surrounding the candle flame. The room with the heater is for all intents and purposes a closed system, so you're not losing any heat produced by the flame copper or not.
    I'd recommend rigging something up where you could suspend a tea kettle filled with water over the flame. It would accomplish the same slower-release of heat, but would also make the air more humid as the water converts to steam. Humid air 'feels' warmer to humans, and you could always use the hot water for tea/coffee/soup.

      It still will radiate heat from the sand itself, so no heat is ever lost.

      If you blow out the candle... the heat will still be there in the sand that's why they call it a sand battery or a heat sink.

      Do you have any consistent sun near a 1st level window? If so, it would be very easy for you to build either a direct Solar-air heating system, and/or a Solar battery thermal air heating system.
      I wish I had the sun to do this on my property, but our property is just way too shaded. The few areas that do get sun for more than an hour or two, are too far away from any windows to be practical.

      What I meant by Solar heating wasn't a large south facing window, but rather Solar collectors outside of a window that pipe in hot air through an insulated window insert.
      These solar collectors are large, highly insulated boxes, painted ultra black (inside), with thermal absorbing materials inside, and reflectors on the outside. Basically sort of like Solar ovens, and they can get quite hot inside (a properly insulated and set up Solar oven can reach around 400* F after a couple hours of direct sun).
      There is a guy in Canada where they have quite low temps, and he does all his daytime heating with Solar collectors. At night, he has to run his wood stove, but using the Solar collectors saves him _a lot_ of wood because he rarely ever has to run the stove during the day.

      I have a homemade (not parabolic) mirror that tracks the Sun and focuses the sunlight on a single line one foot in length and gets the temperature upwards of six thousand degrees fahrenheit. That is too hot for anything except stainless steel. So what I do is run peanut oil through the system.
      I can heat 40 gallon of peanut oil on a clear day in about 40 minutes up to 500°F and then use that in a heat exchanger or to heat air or water or whatever you like.
      Currently, I use the mirror to make charcoal, because cooking oil is just too dangerous & I'm 75.

    Two things to think about. One, yes sand holds heat, and it'll give off heat after the candle flame goes out. For about as long as it took the candle flame to heat up the sand in the first place. You don't gain anything, You just shift the heating down the timeline a bit.
    Secondly, a candle flame gives off about 100 BTU of heat per hour. That equates to around 29 watts. You're not going to heat a space or a room. But it will make a nice hand warmer.

    One thing I'd suggest is a second copper strip perpendicular to the first, forming a +, over which you could place the water dish for a small terra cotta pot.
    The second strip will help heat the sand more evenly.
    The crossed copper strips should support the terra cotta dish and still allow air flow to the candle, while the dish will help to contain and reflect the heat of the flame back onto the copper strips.
    This should help to increase the efficiency of the assembly.

    • @justinw1765
      @justinw1765 19 วันที่ผ่านมา

      Copper coil is hollow and filled with air, so it will depend on the relative mass of either the copper strip or copper coil as to what will work better. If you're going to use a copper coil, you can turn it into a *heat pipe* and/or fill it up with a highly thermally conductive material, and then it will work much, much better.
      To make a heat pipe, you cut a strip of thin fiberglass cloth as long as the coil, run it through from one end to the other (this just acts as a wick for the water). You seal up one end of the copper coil. You put in a little distilled water into the coil. Then take a torch and heat up the whole coil and then seal the other end (quickly, before all the water evaporates out) while it is still hot. It helps to pinch that end before heating it up, so that it limits the water vapor escaping some (you don't want to pinch it completely closed so that it pressurizes and potentially becomes an xplosive of sorts. After all the whole point of this heating is to get rid of the air). Pre-pinching that end also helps to make using solder to seal it easier and faster.
      If you haven't seen a heat pipe in action, I suggest looking it up. It turns regular old copper tubing into something more closely resembling a super conductor (of heat). That is because as the water inside phase changes from a liquid to a gas, it carries a tremendous amount of heat with it (as it spreads through the inside of the tubing), and in turn the copper is pretty good at conducting that heat through.
      And by putting the water under vacuum, you've lowered its boiling point quite a bit, much closer to regular room temps. (Depends on how hard the vacuum is though).

    Either this is stupid, or there is a very specific application where this might do something valuable. The source of heat/energy is the candle and the crisco. If you just burned them by themselves (no copper or bucket of sand) they would introduce the same amount of heat, at approximately the same rate, into the room. In this case, a portion of the heat is absorbed by the sand/bucket first, which would somewhat delay it from heating the room air. A candle flame just isn't much heat. Maybe it would keep a utility closet from freezing if you lost power to your house. I doubt it would add any warmth to an ice fishing shed. What's a real application for this? In the size of room he has it in, it would do practically nothing heatwise. Can someone please explain this to me.

      If you can convert more of the heat into direct, radiant heat and then reflect it towards your body, then it would have some merit. No iteration of a single candle though, will appreciably heat up an average room (not unless the room is both very small and extremely well insulated).
      But to convert it into more radiant heat, you should ditch the sand and copper, and instead suspend a high temp black painted metal can (with a few very small vent holes in the top) above the flame. The metal will heat up and then reemit IR (in the more correct range). Then put an IR reflector in between the shape of a U and V near it, with the open end pointed to you, and with you sitting near it.
      You can get some local, direct, radiant heating with this set up, but the issue is that you have to stay in that one position for awhile to get warm, and again, your room most likely isn't going to warm appreciably.
      Anyways, this is a similar principle of how a camp fire outside on a bitterly cold, windy night can still warm you despite no insulation around the fire and you, the heat sink of the outside, etc i.e. its direct, radiant heating which is very efficient at very _locally_ warming human bodies (but not large spaces necessarily).

    Interesting project. Thanks for sharing it with us.
    I do have a couple of initial reactions to the idea, though.
    First of all, heat rises - and, this design attempts to direct the heat downward. I don't think this is particularly efficient. The copper element also represents a significant expense in what could otherwise be a cheap project.
    What I would suggest is, perhaps, use two metal buckets, one lower chamber that would have air holes at the bottom. Install a few angle brackets near the top to support the upper bucket that would hold the sand. So, you would have the upper bucket containing sand positioned over the Crisco candle in the lower bucket. You might want to also put a few exhaust holes at the top of the lower chamber.
    This would allow the candle to directly heat the sand from below. The heat would continue to rise until all of the sand was heated.
    I think I would probably install other candles in the Crisco can so that I could produce more heat. Having just the one flame extends the burn time, but reduces the area that could be effectively heated.
    Thanks, again!

      There is some merit to converting more of the released heat into direct, radiant heat. Otherwise, the candle by itself will neither heat the room or _you_ appreciably, if barely at all. By converting more of it into radiant heat, you can at least somewhat _locally_ heat you/your body more so (again, of course the room will not appreciably warm, because it is just not enough heat being released).
      Same principle why a camp fire outside, despite bitter cold temps, wind, no insulation, and all that heat sink of the ambient conditions, can still warm you up if you are close enough to it. It's direct, radiant heating which is more efficient at warming human bodies than indirect heating via conduction and convection (which is what most traditional heating relies more on i.e. you heat up the air which gradually transfers heat into the surrounding objects, which then the combo eventually warms you up).
      It will work even better if you take a piece of cardboard, paste some aluminum foil on it with the shiny side on the outside, and fold it into somewhat between a U and V shape, and put that on the other side of the candle/sand/metal bucket/copper, and you sit right near and across from that. You will get even more direct IR heating in this case, because you are directing and reflecting the IR more specifically towards you. (IR normally acts like a diffusive light that goes out in all directions/360* equally from the source of heat. But you can reflect it to harness/concentrate it some).
      But if you want to use radiant heating, you will need to instead suspend a high temp painted metal can above the flame so that it gets warm enough to re-emit in the IR range. (That, or a catalyst mesh, which would be even better, but more expensive and harder to source). Meanwhile, you can take out the sand, copper. Keep the metal bucket just for safety reasons (or use a more shallow tray).

Another question - what if you used a wick (like in a kerosene lantern) in place of the candle?

    Wonder if he didn’t fill it all the way to the top with sand & maybe left about 2-3 inches off the top of the bucket & drilled some holes & maybe used a smaller can of Crisco or other cooking oils in a can, maybe 🤔 …would it help produce more heat outwards. (Hope that makes sense) but all in all it would work for an emergency situation. Very creative. Much love.💗
