In the case of Energy Vault, you can see the cranes themselves in the picture above. The cranes sit on top of the tower, which is where the power is stored. The cranes are mounted in a base that is bolted to the tower. (credit: Energy Vault)

This design is unique, in that only a portion of the cranes sit on top of the tower. The cranes can be mounted in different configurations depending on what they are doing.

Energy Vault uses a "bead" system, a set of flat plastic bricks with each brick in turn mounted at a different height. The brick bricks are pushed at an angle so that they don't fall out, increasing the amount of power that can be stored. The cranes then are placed in a vertical position so that they can be easily removed from the tower and transported down the base. (credit: Energy Vault)

The cranes on Energy Vault's tower are mounted just above the tower, which is where energy storage is stored. The cranes are also positioned in a horizontal position so that they don't fall out.

When power is abundant, it can be used to power other things in the tower. For example, when power is abundant, it can be used to power cars or other vehicles. (credit: Energy Vault)
