The answer is yes, yes.
1. How the earth’s gravity is generated is the effect of gravity. The technology of using the gravitational potential energy of water to generate electricity is already very mature;
2. Tidal power generation also uses the influence of the moon's gravity on the earth's seawater to generate electricity;
Okay, the above are all old sayings, let's talk about unrealized and promising things:
According to quantum physics theory, gravity also originates from positive gravitons, which are an energy level higher than the nuclear energy currently known. Today, the use of nuclear fission to generate electricity has been industrialized, and controllable research on nuclear fusion is intensifying, but Gravitons are currently just speculation (scientists are already using them to explain cosmic phenomena) and are still in the demonstration period. If humans master this energy, let alone generate electricity, they can immigrate to Mars and take a few-day trip outside the solar system. .——This shows how huge this energy is.
