I really love the solution for heating the sand, really simple and effective. Great video! I wish I had the skills to connect a bigger version of this up to my central heating. Heating the battery with cheap overnight electricity and using it during the day would be great for winter. Decarbonises heating and should be much cheaper than oil or gas
Brilliant! What about using a solar panel to power it during the day, then by using a copper coil circuit, pump water through it at night to use the heat? Or atleast a test on the size of solar panel to size of sand battery for maximum efficiency? There are many possiblities with this, thanks for sharing.
Yes,... the power source can be anything to heat the sand battery. And also the system can be made in many ways.
Can I ad cement and heat whit rocket oven ?
What I would love to do is run or at least preheat my backyard foundry. Copper/bronze take a lot of fuel…. Even if I could save a small amount it could mean a lot of savings
Fantastic idea!! thinking outside the box. I was thinking about making a sand battery using a rocket stove and waste oil to heat the battery, but this idea is so much better and easier. I have a wind generator that I would use to power the carbon sand battery, that way I wouldn't need batteries or need as many of them. Robert should try this one. Again, great idea and hope you follow through with more infor on this idea.
Thank you. Yes I will look more into this sand battery
OK, I am trying to build one like yours. I dried the sand and that does not have any conductive. So I used some undried sand and that is conductive, so how much moisture is in your sand. I am using graphite, will that work? or do I have to use carbon black? I have used about half of the graphite and the lowest ohms reading was in the 50's. it is going to take a lot of graphite. if carbon black is better, could you provide a link to get some, most of the carbon black on amazon seems to be non-conductive or for dyeing. I think this idea of conductive sand used in a thermo mass storage device is a game changer.
@@stevejorgensen8123 Hi! My sand is dry because the sand battery heat up over 100 deg C which means that all the water is evaporated. Yes, you can use graphite. 50 ohms os not so bad, because in this case if the ohms are higher then you need higher voltage. Also more you press together the conductive sand more conductive will be.
@@cayrex Thanks for the reply. I tried to compact it and the graphite make it slick, won't stay compact, but did get the ohms down to 50-60 area. Hooked up the battery charger at 6VDC and no go, no current flow. increase voltage to 12 VDC and still no current, increase to 14 VDC and still no current flow. I added some salt and little water, thinking that would improve current flow, no go. I must be missing something or doing something wrong.
@@stevejorgensen8123 Uf, for around 60 ohms you will need higher voltage
Just FYI, love your videos. They are as good as TV shows. Matter of fact I think I’m going to go back and binge your channel!
I also found stainless mesh helped avoid hot spots which became a problem with a tin can as electrode .
Does that replace the copper pipe? How would it be arranged? Thanks!
@@ashmcconnell3868 I had mine go into the bottom and back up again like a u turn but no hard creases !
@@Buzzhummajust wondering if you done more on this. Just starting my journey
@@thomaslloyd82 no i moved on as i found it very messy with graphite and the hot spots where a problem .
Next time to measure glossy metallic object or foil, just put drop of cooking oil over it and smear and you will be able to get temperature reading.
The copper may just seem hotter than the sand because it's a much better conductor. Try painting the pipe flat black to be able to get a reading.
Wow, thank you very much.
This week I foubd,an element heater that uses only 25Watt. I will try it in my sandstove and,will make than a new video.
Great idea, thanks again! 💗
Great and iteresant experiment.
Can you put on bottom layer of gypsum(plaster paris), layer of carbon black with electrical contact with Cu-tube and rest of sand above carbon black whithout mixing with sand?
resistance at the media to copper electrode interface is probably higher than the average? So maybe increased it there.? I'm am wondering what the most durable (oxidation ,corrosion) electrode materials will be. Maybe I'll make one too.
I suppose you could use a peltier device to generate the power after it's hot. It seems a simple thing to try. I'll have to give that a go. Thanks for sharing.
I like the idea. The sand at the beach near where I live is interspersed with a large amount of Iron crystals. I wonder how well it would conduct?
Hmm,.... the iron will be more in form of iron oxide, which is not so conductive.
Hello beautiful video. I wanted to know if you used normal sand or red clay for this experiment?
Thank you. Just normal sand which you can get in construction store.
Unless your using a solar panel to power this, you might as well just use a basic electric heater. The purpose of a sand battery is to store extra energy for later use when the sun isn't up to provide the energy, be it electric or heat.
Correct,... the sand battery store the heat for later.
I was thinking about using a 100 watt incandescent globe encased in clay and keep the bottom exposed to utilise the light at night and then the heat for charging phone or lighting led . Not sure if globe will break with expansion though .
I wonder if you could use this same concept to make a dummy load to test shortwave transmitters?
I like this! Yet, I wish you could tell us more about the following: 1. Did you wet the sand with any electrolyte? Or was it dry? 2. Did you wet the Carbon Black with any electrolyte? Or was it dry? 3. If wet with electrolyte, please measure the voltage, Since then you are making a battery that is dependent on a chemical reaction. If not, then I truly wish you well and hope you are making a follow up video.
I dont wet anything,... no sand and no carbon. The device go o er 100C so in that case the electrolyte will evaporate.
@@cayrex Thanks, now to replicate a little of your effort for us DIY'ers, can you recommend where you got YOUR CARBON BLACK from ? Did you make your own? If, yes then please explain. Another video?
@@cayrex bro if we put on it the peltier cell can have a good power ? Is nice idea if can use in this way for turn on one computer ect...
great work. So what did you use as the carbon black? Something like n220-n330?
Hi Cayrex2, thanks for the great video. I'm not sure about the heat capacity of a pure black carbon powder, but how about to use it without sand? Melting T is higher than sand as well as conductivity of heat and electricity. Have anyone tried it?
Any idea as to efficiency? Would there be a maximum temperature it should reach? Could it be used similar to an ETS unit (electrothermal storage) that can reach very high temperatures?
No idea about efficiency for now. The temperature is based on the power input. Lower power lower temperature and so on. The temperature can be way higher as I get for now
🇨🇦/🇺🇸... Fascinating idea!!!!
How long would a small can like that take to discharge all of its stored heat? How far away can you feel it?
That would depend on the temps starting inside the battery, the temp outside the battery, any insulation on the battery, and how you are drawing the heat out, I.e. are you letting the heat dissipate or do you have air or water running through it?
Excellent
Excellent Job Man ! BRAVO
scrap copper pipe as heater.connector.. gold!
Where do you get carbon black? I tried to google and can't find it. I only found small can of carbon black sells for $16 in amazon. Wasn't sure if that's the same kind. Can you tell me where I can get it? Thanks!
Oh I order the carbons direct from companies like Imerys for super p cabon black or timcal.
Wrap it up in rock wool and put in another container and see how long it can stay hot . I will be putting a tec on mine when they arrive and charge my phone and some led lights 👍🏻
I have several Tec devices to try.
@@cayrex excellent . I guess you sit it on one with a cpu heat sink in ice water ?
IS the black sand a mixture of sand and normal charcoal? Thanks
No,... it is mixed with carbon black. But it can be used a graphite also. Because the carbon black is harder to find.
Hi,Where do you buy that carbon black.
Thank you...very helpful 😊
Best one yet
Genius idea Cayrex.
The paper isolation will probably burn, maybe a piece of mica?
Is that black stuff from your stove or do you buy it?
On high temperatures, yes. Good idea about mica,.... also can be used ceramic or glass wool, etc
@@cayrex And the black stuff? Here in HU is nothing available under this name as "carbon black".
@@lorifilm I think that conductive carbon black is a bit harder to find because is a special stuff for special applications. For that reason you need to search in other countries. Search for super P carbon black, ketjen black, super c45 or c65, acetylene carbon black,..... and so on
@@cayrex Hvala! You can get it in slovenia? (assumed from the sodium silicate bottle)
Good work!
I moved on from the graphite sand battery as the graphite was just was to messy to deal with but conductive carbon might be ok . Don't use graphite ! 😂
Hahahaha
Wow. What if u use a higher voltage? Will there be problems?
Yes,... more temperature 😃
Very cool
Try it with limestone rock dust passing 200 sive.
What is the best way to get the carbon black? Is it normal graphite powder?
Carbon black and graphite is not the same. But you can use graphite. The point is that you make the sand conductive
@@cayrex thank you for your response!
@@TomorrowTom1337 ah, no problem
خطوات موثير ✌
I have a 12 4amps power supply which should be ohms?
Hmmm around 5 to 10 ohms I think
@@cayrex thanks for your reply can i use graphite instead of carbon black?
@@CarTVvNEWcars yes
@@cayrex to what maximum degree can it reach
@@CarTVvNEWcars With good power source,... 500, 800 C,... more
If you insulate with aerogel you be a millionaire. Assuming cheaper way make aerogel.
Heating from 3 Volts: ruclips.net/video/wlElWcbmk_A/видео.html
For god's sake this idea simply will not work at this scale and it also will not die
300kg of sand at 200c going to say 50c when it won't really heat the room is only
.01 kWh
Let that sink in.
That means you can run a 1000w heater for .01 hours
Thats a few minutes at best.
Hahah calm down,.... is just a different idea of sand battery wich uses conductive sand instead of some sort of heating elements.
Why 2 Plus and 2 Minus?
Because for the current. That I am sure that I get all the current to the device. Thicker is the cable lower is the current drop or I my case more cables. Some times I get the problem when I use thin crocodile clips or simillar thin cables.
Yu don’t arf tork funney Bor!
Goodonya
