As wind power, solar power and other power plants increase, it becomes very difficult to store more electricity. California's new startup team Advanced Rail Energy Storage (ARES for short) proposed an innovation: converting electrical energy into gravity potential energy storage.

The specific method is to use extra electricity to drive the electric train, pull the big rock to the hillside, and when the train stops at a high place, the energy is converted into potential energy. When the train carrying the big stone goes down the mountain, the train's motor will be turned into a generator, which will continuously convert gravity into electricity. This method is low cost, environmentally friendly, and safe, and the train and large stones are readily available, as long as there are hills.
