This Battery is Made of Sand

This is a battery made of sand. It’s 23 feet tall, filled with 100 tons of sand, and could be one solution to energy storage. Here's why.

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 😄

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

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

[bcataiji]

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.

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.

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.

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

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

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.

[benzonex]

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

[maniv]

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

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

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 better than just sand, look it up, it's awesome :3

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

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.

[gerharddamm]

I swear to god if this can only use beach and river sand and not excess desert sand… 😡
