....these *'Sand Battery Air Heaters'* are amazing. l use a clay pot, fiII with sand, pIace the bent copper 'L' against the clay pot side, with the 'L Shape" facing inward (saw it in one of your videos). l then pIace on tea candle under each 'L' (in this case, there are five), and one in the center....light the candIes, and piace a red brick on top. The sides of the clay pot get hot, aIong with the brick. l need to get a fan to set on top. ...Thank you for aII of your great ideas!!! :)
@@desertsun02 the brick makes it more of a radiative heater as well as a convective heater, maximizing both for best use of heat conversion, instant heat as well as heating air quality is good - using fresnel collectors to charge them in 20 minutes is an investing idea, would love to see an update with FLIR and air temp readings, timelapse etc.
sure. the fans are heat powered stove fans. they sell dozens of them on amazon. probably best to use a small or medium sized one with this project. even the small ones move plenty of air (without being too bulky). that smallest one i used is only 15 dollars. the copper is listed as 24 gauge (but sometimes it seems a little thicker than that (so 22 gauge would probably be okay too). the length and width of the copper sheet can vary, so it's okay to 'eyeball' that to the size that will fit the pan you are using. i put it all the way down to the bottom (so the fan has a sturdy base to sit on). the easiest way to get the copper is to look on amazon. here's the link to kind i used tinyurl.com/bdejbay4
I've been thinking of using an old aluminum turkey roaster or old old copper bucket. I need sand and some copper strip. Got tea light candles, but was thinking alcohol stove might be good too, since I have a ton of 90% isopropyl and denatured alcohol as well...
you could even use a large stainless pan if you wanted too. yes, alcohol burner should work good too. (i was thinking of using tea lights made with beeswax). i just wish they weren't so expensive.
sounds good 🙂✔ i particularly recommend the 4 tea-light model, that one really cranks out the heat. tip: walmart sells 50 and 100 packs of tealights super cheap (usually $2.50 to $5.00)
daaamn wild I just replied to your two year old video about this, and was going to message you to make a sand battery air heater... and clicked and saw you just uploaded this!! great job, presentation is very good. would love to see durations and air temps of the main flow. try a solar collector for 10-20 minutes and see how long that runs inside and how it warms a room
Quick question(s). Approx how many square feet would you say you get out of each heating unit? Is one unit enough to heat a room to a comfortable temperature and roughly how long does it last? I really appreciate it. I’m rural so these are potential life savers.
hi. it's hard to give exact square feet. i'm currently using it as a space heater. the 4 tealight model with the smaller fan is just like sitting in front of a store bought space heater. works amazing. you can adjust size and strength of the unit by "adding or subtracting" candles, copper, and sand. the tealights themselves typically burn 4 or 5 hours at a time (plus you'll get heat long after they go out). you can also use extended burn tea lights if you want. those can burn 6 hours or 8 hours or even 10 hours at a time.
hi there. they are powered by the heat of the candles. how they work: the base of the fan is metal and actually 'soaks up' the heat off of the copper plates. that heat is transferred to a small thermo-electric device in the fan (called a peltier module or peltier chip). that little device turns heat into electricity and then transfers that energy to the fans motor.
@lisaannwhite4080 awesome! i'm glad you're making the project. tip: the bigger unit with a small to medium size fan seems to be the most effective combination (for maximum heat).
hi yes. i get that copper on amazon. if you search for copper sheet metal 'one pound scrap pack' it comes up. currently it's $17.80. here is the link tinyurl.com/bdejbay4 note that when you buy it this way, they sell you all sorts of sizes and shapes. you can also buy specific sizes but it costs a bit more that way.
I'm sure home depot sells the copper.I would even try a craft store.They might have pieces for crafts or experiments.I found spools of thin copper wire there.
hi. yes, amazon sells lots of these kinds of stove fans. they probably have over 50 different ones. i recommend a small or medium sized one with a starting temp of 122F(50C) (that's the most common type, so you'll have many to choose from)
hi. i never burn more than a few candles or tealights at a time so it's pretty low on any emissions. i've heard beeswax candles and tealights burn cleaner (but they cost more). tealights, in general, burn cleaner than the traditional style taper candles, so that's also a plus
@@MarshaMarshaMarsh4 Room temperature tests would be interesting. That said, assuming you've got some insulation in your walls, if you've got a hot object in a cold room, are you seriously expecting the room to remain cold? That sounds like some crazy magic.
I'm so glad you do these experiments , it helps me out so much, I always look forward to seeing what else you come up with, keep it up!
You have 100% of my support. Just keep doing everything you do!
thank you 🙂🔥

you bet. it's great to hear that you've made the project. the brick will add even more thermal mass (and should be a solid place to put the fan)

an update with timelapse of a clock and these, and some thermometer readings would make this a very scientific video! great job
You're a genius. The Universe has blessed you with positive energy. I love your videos!✨️🪷💚💚💚
hi there. i'm glad you like the vids 🙂✔🔥
Cool. Could you provide a list of materials? Such as what kind of fans you are using, gauge and size of copper sheets etc?

...you couId aIso use 'Crisco' shortening and a candIe in a canning jar pIaced in a large clay pot or metal bucket...they Iast for days :)
I may have to use this as a emergency heat source /Christmas gift. 😊

How the fans work
hi there. they are powered by the heat of the candles. how they work: the base of the fan is metal and actually 'soaks up' the heat off of the copper plates. that heat is transferred to a small thermo-electric device in the fan (called a peltier module or peltier chip). that little device turns heat into electricity and then transfers that energy to the fans motor.
Ordered the supplies and am going to give it a go. Thank you!
@lisaannwhite4080 awesome! i'm glad you're making the project. tip: the bigger unit with a small to medium size fan seems to be the most effective combination (for maximum heat).
can they heat a smaller space effectively if there is no power?
are these more effective at heating than just putting lit candles on the table?
Do you have a source or link to that thin copper? Maybe in one of your other videos?
hi yes. i get that copper on amazon. if you search for copper sheet metal 'one pound scrap pack' it comes up. currently it's $17.80. here is the link tinyurl.com/bdejbay4
note that when you buy it this way, they sell you all sorts of sizes and shapes. you can also buy specific sizes but it costs a bit more that way.

What type of stove type fan are you using, is it on amazon. This set up looks great-feel a project coming on. Keep up the brilliant videos please.
hi. yes, amazon sells lots of these kinds of stove fans. they probably have over 50 different ones. i recommend a small or medium sized one with a starting temp of 122F(50C) (that's the most common type, so you'll have many to choose from)
Where do you buy copper at?
hi. best place i know of is amazon. this is the link to what i use tinyurl.com/bdejbay4
I'm slightly afraid for your health with all the candle emissions, but your projects are always fun~
hi. i never burn more than a few candles or tealights at a time so it's pretty low on any emissions. i've heard beeswax candles and tealights burn cleaner (but they cost more). tealights, in general, burn cleaner than the traditional style taper candles, so that's also a plus
@@desertsun02 Excellent to hear~

“It worked” 🐽 😂- your click bait!
hi. clickbait? no clickbait. this project is 100% real. 🙂
@ did it though? Test the room temp 😉 🙃
@@MarshaMarshaMarsh4 ...yes, it does work!!! l heat a space using these *'Sand Heaters'* :)
yes, these definitely work. (especially the one with 4 candles). that thing is amazing.
