Why can’t energy be harnessed through gravity?
We already harness energy from gravity… just not in the way your friend thinks. Hydroelectric dams use their height to store potential energy in a reservoir.
The Short Answer
We already harness energy from gravity… just not in the way your friend thinks. Hydroelectric dams use their height to store potential energy in a reservoir. The height difference between the water and the turbines means that gravity is used to move water past turbines thus creating energy.
