Thanks for your sharing. Perhaps in the future once gravity is better understood, we will know if it can be depleted.

I imagine 200 years ago nobody worried overly much about burning coal or later, kerosene etc. The atmosphere is a pretty huge volume and besides, the rain cleans the air. ... one can imagine sentiments like that being directed at anyone complaining about air pollution.

Hmm... for example, the scheme of solar or tidal energy to move water uphill, then grab hydroelectricity? is an example of storing gravity? is that a valid characterization?

And yes, you immediately got the worry; that accessing gravity would at scale over a few hundred years, be a danger.
