Good idea. Woodsmen used to dig a pit for their campfire and put large rocks in it. When ready to sleep they filled in the fire pit with dirt and slept on it. I tired it once in Alaska. It was cold for about 20 minutes but then it got so hot we had to move. It was still warm in the morning. Dirt/rocks can store a lot of heat. Parabolic mirrors could direct a lot of energy to be stored in dirt.
Shared everywhere. Great show! It would be amazing if these guys contacted Australian government, they have dug massive open cuts in Gippsland, Victoria and they stuck the poor here to live in the smog and poisoned water. Thanks in advance.
Im a retired power engineer. The bigger issue in Australia is cooling demands. And guess what? You can freeze a mass just as readily as you can heat it.

A very nice interview, could we please have an interview about Heliogen they are taking solar CSO to the next level by being able to reach 1500 °C which open the door to new exciting fields like carbon free hydrogen and cement production.
Its been three years since I first saw this idea. And 18 months since I buried a 750gal tank in my back yard here in Saskatchewan. I am completely off grid up here in an 1800 sq ft home built in the 70's. I added an extra 16kw of solar to my system. Even on cloudy days the batteries are full ASAP and Im dumping between 4-12kw of energy into that tank an hour. Every day of the year. It was not hard to justify the solar. Its replacing a $3000 heating oil bill. Top of that tank right now is 581C. At the end of February before the days are long enough for me to start moving the needle the other way? It will be around 190C
The issue is how to dig a 100 foot deep hole for a sand pit that won't leak or contact ground water. So it takes a lot of concrete to build the underground storage...actually Evacuated tube solar water heaters are very effective at heating such a project and circulate the heat like a closed loop geothermal system.
Great stuff !!! i really hope they succeed. Here in Canada we already have molten salt technology but again it is much more expensive than what these guys are talking about. Thx. for the video.
So many engineers working on our future! There is hope! (However sometimes I think that these smaller companies could benefit for spokes persons that are native English speakers. Phew, that was hard to follow,)
Yes here in America we have quarries in the middle of every major city I have 3 in my backyard...this is good for towns not cities since has to be 3 miles away
thats quite practical for the region from they are, those countries produce lots of excess electricity n they can either sell that or use that excess for heating like they are doing, and also for houses with solar systems which produce excess electricity and the area is not connected with a grid for Net Metering thats good solution, quite clever large scale implementation thats an amazing channel, i found it after watching Liquid Metal Battery solution
Even in a warm area, you still need hot water for dishwashers, laundry machines, and bathing. Also in the desert it can get cold at night in the winter. You may not need much heat but you do need some. What is nice in the warmer areas of the US a system for a home could be much smaller and affordable. Also in warm areas people often have swimming pools and if they are not heated it feels too cold. Many people, (especially children, elderly or handicapped), like a swimming pool to be in the 80's or even close to 90 degrees, and even more in a hot tub. To keep a swimming or therapy pool very warm year round is expensive. The swimming pool and hot tub industry would be very interested in this technology. More people would want pools if they were affordable to heat. Keeping a pool warm can also be a big expense for hotels, resorts, schools, colleges, community centers, rehabilitation facilities, and health clubs.Think how much it must cost a hospital to provide so much hot water for all those people and to launder many sheets and blankets, and to sterilize things.
Zack and Jessie, always great information. Have you done any research into the “Trompe, compressed air” apparatus? Great technology that should be resurrected.
I have an AGA heat storage cooker. Overnight it heats up a big brick inside using cheap grid electricity from nuclear power stations which cannot switch off. Then a fan keeps the ovens hot by blowing hot air around the brick and the ovens. The Aga cooker was invented in 1922 by the Nobel Prize-winning Swedish physicist Gustaf Dalén (1869-1937), who was employed as the chief engineer of the Swedish AGA company (Swedish Aktiebolaget Svenska Gasaccumulator, English Swedish Gas Accumulator, Limited).
So combine this storage with plasma jet incineration for urban waste and solve many problems at once. The waste slag can be ground as the filler for the heat storage medium.
Yes usually heat is as the lowest tier of energy, and is the waste product resultant from inefficiencies in the machines that engineers are developing. But in this case their are addressing the need for heating of living spaces and industries, without burning carbon based fuels. You have to consider the problem being solved. Yes there are countries where too much heat is the problem. But there are also countries where cold temperatures are the problem. Those places are far from each other and had it been feasible to just transport the heat from countries in the tropical climates to countries nearer to the Arctic climates we would have already build something that could do so. But it isn't so people have instead been burning polluting fuels for many years. The problem of heating and cooling is a local problem. Which is why solar cells on the roof powering an aircondition is a good solution in hot countries and this is a good solution for heating homes in cold countries.
First question that comes to mind which was not asked - house do you use the heat? Perhaps heated air circulating through pipes. But can this be used for making steel?
very interessting how exactly is the sand heated - regular electric heaters or some diods (which require a lot of peack power) or maybe some microwaves or infrared heaters?
IF there is no requirement, what about crushed glass. It can not be used to replenish beaches, but can it be used for energy storage? Can the heat be used to run steam generator.
But do you have the amount of energy stored per cubic metre at say 500degrees C Also what form of resistive heaters are use ie nichrome ? Also you say A metre insulation of material rockmineral or what is best ?
Wow, a thermal pile. I have a house that does that. It heats up buried gravel & rocks when electricity is cheap and stores the heat. This is only decades old technology.
>3600 square foot home. Water, gas & electric costs per year, combined? $1920 a year. $160 a month. You can heat pressurized brine above 100C. Also a decades old method.
The heat pumps have almost nothing to do with this heat collector. The heat pump leverages the difference between outer and inner temperature difference given that outer temperature is granted for free and unlimited. Thus, we cool the outer air to heat inner air, while colled outer air in the outer thermal exchanger is continually exchanged with a bit warmer outer air. But the heat in the heat storage is not free. It is not like outdoor air. Not that abundant and heated for free by Sun. And as was mentioned, the operational temperature range is not that practical or even feasible for the heat pump to improve the situation. The water heat collectors whether built upon the sand heat collector infrastructure or locally (inside the buildings) would be a good addition as they can save heat generated by solar heat collectors (non-electric), and glycol-water solution also known for its high thermal capacity. And yeah, water in a static separates in thermal layers by its amazing nature. Out there are a lot of heat collectors/exchangers that are very good in the distribution of heat of the different temperatures from one whole water-based liquid body. They use the number of horizontal heat exchanging loops at different heights to withdraw heat of appropriate temperatures for heating floors, showers, etc. And it is a very flexible system.
Heat loss is proportional to the temperature differential. Therefore this can only be efficient if stored short term. I dont see this being a game changer.
They were talking about several hundred degree differences though. And the heat capacity of the overall storage system is key, as that tells you how long you can maintain that heat flux. In many ways this is most useful when your purpose is to generate heat from the stored energy, which is of obvious benefit in cold places like Finland, or Wisconsin, or Minnesota. If your purpose is to generate electricity it may not be as useful. But there are many situations where heat is what you're after. Regardless, sticking thermocouples or Stirling engines in there could be useful. And yes, putting in the solid metal "batteries" is, as we Americans say, a no-brainer - to test. They will "steal" some of the heat of course, but there is i expect a tradeoff curve of electricity generated by the hybrid system of dirt + metal batteries versus heat capacity reduced.
@@alvarofernandez5118 Exactly. Thermal systems do better when the maximum temperature is as close as possible to the working and ambient temperatures. The greater the difference the larger is the heat loss.... And then insulation becomes a major cost factor.
I wonder how they would heat the sand thoroughly. In a natural desert the heat is stored only at the top of the sand while the sand inside is cooler. They would have to churn the sand to get it all thoroughly heated
This video would have to go door to door in the appropriate district, because if the demand doesn't come directly from Home-owners who do Vote, vested interests will prevent anything happening they don't collect the Rent on.

There must be Some joke in there about buying hot sand from the dessert? Indeed, we need massive Energy Storage that costs pennies. Sand is Also suitable as low temperature Storage where IT can be Used to store heat from summer, for heating distributed heated homes in Winther. A pilot project in my country does just that and to compensate for the lower upstream temperature Of the water in the heating Grid, heatpumps are installed at the customers. That way No high tech batteries are needed and insulating an Underground blob of sand, so IT keeps warm for 6 months, is not as difficult as IT sounds.
Well, the heating of the Sand, comes from wind and photovoltaic. I get that, but even if the electricity acquired from those power plants is cheaper, you are still paying for electricity to heat and store. Ok...what happens when wind and photovoltaic aren't available from the power plants , do you buy at higher prices just to make your system work? What if the electric grid is down? Actually what you're selling is another alternative to Storage. Heat Storage. Why not just generate electricity from that specific cheap excess electricity from wind and solar right at the point of need? I watched the whole long video and I agree that your system is "green & novel" but here in the USA , because of Energy and Power laws and regulations within any city, your system is not favorable, although a pretty good system. Best wishes to you and hope you can incorporate vertical windmills above your Heat Storage buildings to offset costs.
I have a 105 amp alternator and one flywheel from exercise bike and one washing machine motor and 200amp isolator. Under 500$ for continuous electricity off grid. No electricity Bill's.
But to heat a sky scrapper or cool it or make fresh water from salt water.. no bike can do the job by itself.. their systems isn't made for off-grid for sure.. it's been made for a resilient grid.. and make it even more resilient..
If you ask me tough.. I'll prefer everyone off grid.. but they don't want that and we can't force them, then there's solution for thems like the one from polar night
And *WHERE* does all the sand come from? There is a worldwide sand shortage. Even if you use round sand: what huge area are you going to excavate and transport? Huge sand mining operations? Industrial scale Earth destruction to get all the sand? You have to dig-out the same area you fill in, volume is 1:1, right? And NO, you CAN'T use the Sahara desert. That provides phosphate to the Amazon rain forest. (It used to be a fertile area with lots of stored biological nutrients that are 100% needed to support the Amazon. It replenishes phosphorus that the forests use, by weather deposition). Are you aware of the wordwide sand shortage? Please google it. Farmland is being ripped up, massive deforestation, Mekong Delta is being stripped by sand dredging, environmentalists are being murdered by sand cartels. It's a scarce recourse. Even non-concrete sand has a large environmental footprint. Please do your homework guys. ...

A private geothermal system. Instead of using magma they use excess wind power or excess solar. Excellent idea.

Not only viable as green energy, but as a business by bying electricity when it's cheap, and selling it as heat with a profit. Good idea.
Could you cool it to -100°C for the summer?
Might be hard to cool with waste "coolth". No magnifying glass etc.

I watched the whole long video and I agree that your system is "green & novel" but here in the USA , because of Energy and Power laws and regulations within any city, your system is not favorable, although a pretty good system.
Best wishes to you and hope you can incorporate vertical windmills above your Heat Storage buildings to offset costs.

Heat pump
just add steam turbines (regular, hit-or-miss, tesla) for steamed sea wated to have stored heat (compare to stored hydro) electricity generation
your faith has healed you, not knowledge, stop touching me
knowledge will make you dumb, have the skill instead
base on faith, not law, any type
sea water desalination combo heat storage plant
with those turbines combined, three parts

I have a 105 amp alternator and one flywheel from exercise bike and one washing machine motor and 200amp isolator. Under 500$ for continuous electricity off grid. No electricity Bill's.

But to heat a sky scrapper or cool it or make fresh water from salt water.. no bike can do the job by itself.. their systems isn't made for off-grid for sure.. it's been made for a resilient grid.. and make it even more resilient..
If you ask me tough.. I'll prefer everyone off grid.. but they don't want that and we can't force them, then there's solution for thems like the one from polar night
And *WHERE* does all the sand come from?
There is a worldwide sand shortage.
Even if you use round sand: what huge area are you going to excavate and transport? Huge sand mining operations? Industrial scale Earth destruction to get all the sand? You have to dig-out the same area you fill in, volume is 1:1, right?
And NO, you CAN'T use the Sahara desert. That provides phosphate to the Amazon rain forest. (It used to be a fertile area with lots of stored biological nutrients that are 100% needed to support the Amazon. It replenishes phosphorus that the forests use, by weather deposition).
Are you aware of the wordwide sand shortage? Please google it. Farmland is being ripped up, massive deforestation, Mekong Delta is being stripped by sand dredging, environmentalists are being murdered by sand cartels. It's a scarce recourse. Even non-concrete sand has a large environmental footprint.
Please do your homework guys.

@Craig Whitley It's basic high-school supply and demand.
Perhaps you would do well to actually learn of the problem, instead of making assumptions.
Isn't Hydrogen still clean energy? Converting H2O to hydrogen. How much carbon is produced from burning hydrogen? Burning grease from fast food restaurants in diesel engines smells like french fries 🍟!🤔👍😍 Every car in America burning Grease smells better than carbon monoxide?🤔😆
I’ve got a much better process
@30:22 why you try to explain what you dont understand ? Take it easy 😂😂😂
