All fun and games until some guy falls in it and turns to sandman

Thank you for telling us what it was in Celsius for the rest of the world Edit: for all the haters in the comment,thanks for the likes 😄

“Without much loss” is a vague way of saying, “I dont know the efficiency, there’s a good chance its useless”.

The "future" when this was used in the 70s and earlier using dirt, water, and rocks, as heat storage. Use it to store heat from the summer, cooling the homes, and heating them with that heat in the winter.

I wish there were details on how the energy leaves the sand.

"Hey sorry my phone was dead, I forgot to charge my 100 tons of sand"

we use the same kind of technology where we store it in the ground/mountain rock underneath the house. The heat it stores there is then used to re-heat the house over the year.

Ah, sand bombs. My favorite

The battery: _is made of a ton of sand_ Anakin Skywalker: _[confused screaming]_

You forgot to say how they convert the heat back to electrical energy. It would be nice to know the overall efficiency after all conversions, as well.

america be like:- sand need democracy 😂😂

Very impressive, now she has to explain how to fit a 100 ton, 23 ft battery in my two bedroom house.

I feel like America’s gonna invade countries with lots of sand -oh wait

Grandpa had a 1,000 gl. Tank that he had flu pipes and water lines in , the tank was full of sand. He would burn wood or Cole in a berner made in the side of the tank. This would heat the sand during the day, so he didn't have to leave a fire unattended at night. He got most of the parts from pulling out an old boiler. From a house that he was remodeling, the owner wanted a gas furnace put in. And he only had to go out a few times a day to stoke the fire. And it was always nice and toasty in the mornings when we were having breakfast, after which he would start stoking the fire again. Once again old technology being used in a new way.

“Who cares when you have space?!”😆😂

The future of not having enough sand lol

In Spain, in the Tabernas Desert, there's a MASSIVE solar farm which uses a similar method however, replace sand with salt, it's more expensive, however, it stores the heat muuuuuuch better than just sand, look it up, it's awesome :3

The only downfall is that the neighborhood cats keep pooping in it

so ur telling me we invented all these genuis and increasingly complicated battery designs just to end up with the conclusion that literally just heating up sand is the most efficient way to store energy lmao

i cant wait for sand powered cars

"Sorry I'm American" is the most non-American thing I've ever heard 😂

Phase 1: Heat up sand Phase 2: ??? Phase 3: Get energy back

Looks like the dessert is gonna be a mega battery.

BUT, hear me out, how about we do the same thing with water and instead of heating it, we place it higher so we can use it later for energy. Hydroelectric dam would be a catchy name I think.

If it can use desert sand, great! We have that in abundance with little use for it. If it relies on beach/sea/ocean sand, then it's not good, because that's actually a relatively scarce resource.

" I don't like sand"-Anakin Skywalker

"sorry I'm an American" Justice

Yes I definitely have space to store 100 tons of sand in my 2 bedroom apartment

Sand is a problem because there's an air gap inside. Poor conductor. Plus, the tubing will get cooled down so that the ambient heat can't reach there anymore. That's why molten salt was a consideration but it requires much more heat.

This is what we need in Africa. Convert the Sahara into a battery for the continent 😎

deserted regions with sand bout to get some freedom soon

This lady believes in unicorns

There is actually a shortage of sand in the world due to concrete construction.

You skipped the step where the heat becomes electricity.

I feel supercharged now

Forgot to note it takes up a shit ton of space and is not efficient to transfer back into electricity.

Concrete industry just entered the chat.

Thanks, my HOA hates it

Don't apologize for being an American; don't apologize for being you.

This would be useful for people in cold climates to supplement their heating instead of relying solely on oil or gas. Good stuff.

My dumbass thought the sand would turn to glass if you do that.

The problem isn't heating the sand, it's getting the heat back into electricity

Ok boys now we wait for BasicallyHomeless to make a sand powered PC

I had a similar idea before I knew about it. it's good to see it being used successfully somewhere by someone

There was old tech called a storage heater - basically a big lump of concrete with a heating coil in it, in an aesthetically pleasing box. It would be heated by low cost off peak electricity at night and during the day keep the house warm. Similar principle.

Watching this, I was thinking: that's very similar to the sand battery I heard about in Finland. Then I realize, you are talking about that exact battery.

It might hold heat but getting heat back to electricity is one of many kinds biggest challenges (to do efficiently)

That’s pretty neat. Couple of questions: 1: How long does it take to heat up to 1000c using waste heat from solar? (I looked it up, and the actual idea is to heat up to 1000c, not 1000f) 2: how much heat loss are we talking from just sitting around? Not that much isn’t an answer if you’re planning on using this tech to heat people’s homes, especially if it gets cold in the winter. 3: how efficient is it? Extended from 2, if we’re talking about using it to heat homes in the winter, how do you plan on transporting that heat to each location? If you’re doing radiant heat, and just moving hot water, the plumbing used to transport it will waste even more heat, and simply dump it into the ground through the pipes. If you plan on using the heat to heat steam to power a turbine, you’re wasting just as much energy by using electric heating, and that’s before you even think about how many watts you could even generate off of these things by hooking them up to a steam turbine generator. After looking into it, even a few sources that have a clear bias towards “sustainable energy” solutions are skeptical about how useful this actually is. The best thing I’ve seen said about it from a source that actually seems to put some critical thinking into the matter is that it could be a way of harvesting a little extra energy out of solar, but it isn’t going to do what everyone claims it can, and it is by no means efficient.

Is this why I feel so "energized " when I go to the beach?

"Sorry I'm an American." These Canadian immigrants are getting better at hiding their French accents.

Thanks for the conversion to real units

This is something you would see in Arrakis

Well, I hope we use desert sand. We already have a sand crisis.

“I hate sand. It’s rough and coarse and gets everywhere”

Nickle hydrogen batteries seem like the better option to be honest

These cost over 200,000 bucks and can provide enough to power one small single family home for a few day in fairly cold weather to just a day in severely cold weather.

Every energy resource is “cheap” and “Abundant” until more than three people need it to get to work every day.

Need more details into this

More importantly it's far safer. Even if they reached the energy density of lithium by actually superheating it I'd argue that dealing with 100 tons of molten glass would be far easier than just 10 tons of lithium cells going up in flames

*Sand mafia enters the chat*

I was an engineer at a major aerospace corp, and our pilot plant used sand... soaked with car oil.

I love unique battery designs. My favourite are analogue batteries like ones that use water displacement (pump water up when energy is abundant; let water out to spin turbines when energy is scarce).

I dont like sand - A certain jedi

This is cool, but I've never laughed harder then when I heard "excess wind and solar power."

Take it with a grain of "salt" or should i say "sand". The efficiency isn't nearly as close in reality towards their claims. It costs $200,000 USD, not for the sand or the storage tank but for the insane Solar array you need to keep it warm. It is more cost effective to use that energy created by solar panels to directly use that energy for heating, lights, fridge... And it probably costs $3000 in equipment per home to do so.

Thank you for telling us how much energy they can hold and how great the efficiency would be! Oh wait…

Sounds like geothermal energy but with more steps

Some lightsaber wielding guy would be very mad when he found out about this battery

I knew a guy who built his own system like this to heat his home. The problem with sand heating and cooling is that it expands and contracts. When it contracts it settles deeper. Then it expands as it heats up and hydraulically destroys the container. I wonder how they got around that. Maybe with something that holds it in smaller units....but it's not just a big can of sand. That just doesn't work.

"with the right insulation"... exactly. Also, with the right efficiency, with the right cost, with the right energy production source, with the right...

Sand cools very quickly 😂😂😂

"sorry im an American" 😂😂😂

another thing we wouldn't need if we went nuclear energy

This is how my house stores energy. House is 20 years old and stores the energy in the ground below it using a system of pipes in the piles below the home.

Imagine the amount of energy it will take to heat that thing up every time.

I find it pretty cool when we talk about long time storage but the reverse conversion into electricity isn't very much efficient... So maybe it isn't that amazing

Make sure you only use non-concret grade sand, because there is a shortage of that type.

Everyone thinks sand is plentiful, but there's actually a sand crisis.

Sand shortage moment

Sand is one of the most critical ressource on the planet, controlled mainly by the black market

Anakin: *Somewhat satisfied*

Imagine every house having one of these and a tornado goes through the neighborhood.

I love the fact that she, as an American, did not just assume that all the audience will be American and did the conversion for us ❤❤

Gravity batteries are more useful since the potential energy can be converted to electricity.

Ah yes a sand battery. That's exactly what my Tesla needed.

Sand doesn't grow naughty little tendrils and turn its container into a spicy pillow, so there's that.

First, you crush on her, then you subscribe...

Sand is a dwindling resource.

Used for district heating. BBC did an excellent video on it last year.

Would be interested to hear about the new iron-air batteries that being used for utility-scale electrical storage.

It also doesn't explode in a nearly inextinguishable fire if all hell breaks loose.

Let’s see it stay that hot when it’s -35 degrees here

Isn't sand projected to be a scarce ressource in the near future?

I feel like this is an electric-earth type pokemon

brb gonna use a sand timer for my phones now

Not only will it not work but people keep forgetting about winter

And environmentally friendly. Wow, no corrosive and toxic chemicals. Before watching my assumption was a method to capture static electricity in sand, but this is cooler. Simplistic, little to no moving parts, easy to mass produce.

I need that to replace the battery in my EV.

For heating homes alone, yes it's a game changer

glass be like: seriously
