[00:00:01] Speaker 1: Musique C'est du bois croustillant qui peut tenir la température vraiment bien. Il a une capacité thermique très haute. C'est quelque chose de très cher. On n'a pas besoin de ce type de sable dans un short. Musique Le l'eau chauffée pour la batterie de sable vient d'ici.

[00:00:48] Speaker 2: Musique Il circule dans le bâtiment et l'eau utilisée va retourner dans la batterie de sable. Elle sera rechargée et retournée à l'éleveur. C'est un coup d'électricité. Vous avez toujours l'éleveur là-bas. Ce n'est pas dépendant du monde extérieur.

Summary

The speakers describe a sand battery heating system. Heated water circulates through a building and then returns to the sand battery to be recharged, providing a self-contained heat source not dependent on outside conditions, though certain high thermal-capacity materials are expensive and unnecessary for this setup.

Key Takeaways

A sand battery can store heat effectively due to high thermal capacity.
Hot water is heated at the sand battery and circulated through the building.
The return water goes back to the sand battery to be reheated, creating a loop.
The system can remain operational without relying on external conditions or sources.
Some high-performance thermal materials are costly and may be unnecessary for this application.
