swansont Posted February 28, 2021 Share Posted February 28, 2021 Yes. One effort is hydroelectricity. Gravitational PE of water is converted to rotational KE of a turbine, which makes electricity. also: https://deciwatt.global/gravitylight bypasses the need for water Link to comment Share on other sites More sharing options...
iNow Posted February 28, 2021 Share Posted February 28, 2021 I find the advanced rail energy storage system to be a cool idea, but may not be precisely what’s being sought by the OP https://interestingengineering.com/energy-storage-trains-work-power-gravity Link to comment Share on other sites More sharing options...
studiot Posted February 28, 2021 Share Posted February 28, 2021 One of the oldest still working machines in the world is powered totally by gravity. Gravity is so reliable. Link to comment Share on other sites More sharing options...
MigL Posted February 28, 2021 Share Posted February 28, 2021 And for really esoteric methods ... Throwing a mass tangentially around a rotating Blacjk Hole, stealing some of the BH's angular momentum through the frame dragging effect, and having the mass come back with much higher kinetic energy.

Photon Guy Posted March 1, 2021 Share Posted March 1, 2021 How about a water wheel, isn't that harnessing gravity to power a motor? If you've got a waterfall and you build a water wheel, you're using gravity to make the wheel move. Link to comment Share on other sites More sharing options...
