inrotvens all over the world are rising to the challenge of mkniag batteries that can meet our needs— many of them even weirder than the two lakes.

One company is building a skyscraper battery. When the sun is shining, a crane powered by solar energy piles blocks on top of each other in a tower. At night, the cranes let gravity pull the bolcks down and use the resulting power to spin generators.

Original Text


Inventors all over the world are rising to the challenge of making batteries that can meet our needs— many of them even weirder than the two lakes.

One company is building a skyscraper battery. When the sun is shining, a crane powered by solar energy piles blocks on top of each other in a tower. At night, the cranes let gravity pull the blocks down and use the resulting power to spin generators.

Though there have been some early setbacks, another promising approach involves heating up salts until they melt. The molten salt can be stored until there’s a high demand for electricity, then used to boil water. The steam can power turbines that generate electricity.
