I'm an engineer working with Nitinol, Ive been working on a way to power a ranch using a Nitinol engine that uses a sand battery for its needed heat exchange during the nightime hours. I dont know why anyone isnt working with this very simple and very effective technology but they should be. Its something most handy people can build and easily power their homes

Maybe make a big metal spiral (or few of them), like in electric oven, then put them inside the sand, to heat it up to at least 250-300 Celsius or much more! Can end up requiring few kW of power (with few spirals), but looks like a decent idea to test it. And it would be great, if you really decided to repeat the experiment with bigger container! ♥

This is certainly an interesting thought. I work at a sand mine where I dry sand with a giant rotating oven and send it to a silo; and a month after filling it, it still comes out of the silos very hot. I had not thought about how it held heat but it certainly is giving me a few creative ideas.

Gravel is better suited for this purpose, because of the gaps between the individual stones they can easily be heated by passing hot air through them and then there is no need for copper tubes

5 hours for 5kg is not bad at all. It would be a pretty good system to put a sand battery in a basement of a home and store all the heat in there.

except the method to heat it was very expensive

Maybe we should be putting sand batteries underground for better insulation? Another possibility is that we can store cold as well as heat. The idea is to create a temperature differential. It doesn't really matter if your thermal storage is hotter or colder than the ambient. So we could store heat in the day to power the night, and cold in the night to power the day. With refinements, there might be a way to use the heat differential between the heat store and the cold store to get a higher differential that's sustainable over the time it would take secondary system to charge its hot and cold sides. Or maybe you would need to rotate 3 or 4 systems depending on the recharge time. That's something for the research to figure out. That's a simplification as temperatures are more complicated than that, but it's the general idea. It's going to be fun watching the tech develop in this area.

One of my favorite topics! I wanted to build a prototype where I would put some sand in a (heat-insulating type)cement box, and have the heat transfer with (compressor)parts salvaged from AC. The whole thing(heating included) would run on some solar panels, so long term energy storage testing could have been made possible..

I wanted to build it too, with double sheet metal enclosure with glass window on the outer enclosure and vacuum between those two metal enclosures. Would use mirrors to direct sun energy trough that mirror to heat internal enclosure with sand inside. There would be pipes around outer encloser and it would be well insulated. So when you want to heat the water that you are pushing through those pipes, you just lower the vacuum between those two enclosures and the heat from inside enclosure start to heat outer one with pipes..

I would like to see you use a sand battery to heat a greenhouse at night. Heat the sand with a 12-volt electric hot water heater heat element that gets it's electricity directly from a solar panel. It would never actually be switched off. When the sun is shining the electricity from the solar panel heats the sand. At night when the sun is not shining the hot sand gives up the heat to the greenhouse. Can you do that?

The DIYers who have tried this found that they needed to swap out the water heater for a stove coil. The water heater element was burning up without being submerged in water to cool it. Also expanding the stove coil so that the heat dispersed better throughout the sand seemed to have better results.

sand will heat up slowly and release the stored heat slowly to air. With waters higher storage capability, it's like this would drain the sand of heat much faster than air.

Instead of using a liquid with a low boiling temperature, you can use a water's vacuum boiler/heat exchanger to produce steam. Vacuum boiler brings the boiling point of water significantly down

Please build a bigger one. Also, test using electric heating element vs hot water to put heat in storage and other loops to carry heat out to be used for room heating, cooking/baking, drying food for preservation, drying clothes, and distlling water for safety.

What if you heated the sand with the same technique used to make a fluidized bed?

Try using molten lead as the conductor, or mercury, instead of air. Make the spiral tubing and checkout the tubes/kg of sand.

I am thinking a sand battery can be used to store direct solar radiation heat for use as radiating heat in the nighttime. The sand can be heated during the day and moved into a house or my main idea being into a camper or van. Ideally it doesn't have to be moved, but that means it would have to direct dangerous high amount of concentrated solar into the middle of a living space during the day. Too dangerous at first glance. This method can be used to provide supplemental heat above which a more controlled heating method such as the standard heating method can control the temperature, and its use will clearly go up as the sand loses its heat later in the night. Another idea that many others have had before me too is to use a sand battery to be able to convert to electric energy at night (or any future time before heat has naturally dissipated). Converting sand heat into electricity is an interesting challenge that I don't think has been attempted on a DIY / personal scale. Finally, it may be possible to produce a sand 'cartridge' which is a box shaped container of sand that can be heated with an array of concentrating mirrors. This box can be be the shape of a mattress or half of that possibly. After the sun sets, it can be slid into a frame space carefully located under a mattress, the frame which has insulation on all sides. The top side can be adjust to release more or less heat. This might be practical in van camping where the mattresses tend to be in the back of the van and there is usually space underneath them for storage. A real simple analog albeit small scale, is the hot water bottle which I previously thought as laughable but is an excellent method to maintain warmth and is used by many people.

I've been thinking the same thing. At this point in thinking about it I'd like a rocket heater on a dolly with the sand as mass. The large rubber tires make it easy to move outside to fire up the rocket heater to heat up the mass before night fall. Then put the rocket heater fire out and wheel it indoors to radiate the heat for hours. Even without a fan on it, it would slowly release through the night which is fine. Separating the rocket heater from the mass would be tricky to make resilient but if it could be done you could add more mass (sand) and a more powerful rocket heater that's stationary outside.

What hot air being injected directly underneath/in the sand to cause liquefaction? To get the temperature up quicker; at higher volumes of sand, more air inlet manifolds (injection points) maybe be embedded in the sand.

Wow nice video! :D We are working on it to turn the heat from the sand back to electricity. And many cases we can use the waste heat from the turbine condenser so the efficiency goes up significantly. Total efficiency can be as high as 90% for combined heat and power plant. You can also wonder why we just don't stop all the cars and condensing power plants which has similar efficiency, 20-30%? XDD

They have done this in Denmark

The surface area, where the heat loss happens, increseas slower than the volume. That's why this technique works best with large units. Sand is also poor heat conductor, so in a way it's an insulator itself.

Please make a larger sand battery that's on a dolly. You heat it up outside and then roll the dolly sand container to indoors to radiate for hours. Perhaps it can be heated with rocket mass stove using the sand as a thermal mass. Maybe the rocket mass stove is integrated with the sand on the dolly. The above dolly/sand/rocket mass would be practical tool to heat a home in an emergency or supplement a heat pump when it's less than -15C outside.

One thing to consider, just like it is inefficient to convert heat to energy, it is inneficient to convert energy to heat to store it, it is better to produce thermal energy and store it which can be done with modified renewables

One UBS powered mini desk fan. Be sure to set that milk can on something to insulate it from the floor. One 12 volt car battery. Solar panel of sufficient wattage to charge the car battery from the drain overnight. From the solar panel to the car battery. Battery to the heating element. Mini fan to a socket UBS charger hooked to the battery (drain on the battery will be negligible). Fan to stir the heat coming off the milk can. Will sufficiently heat a 12 foot by 12 cabin over night for sleeping. And the remaining heat at the top of the can will heat an 8 in frying pan to cook your breakfast.
