On: Ask HN: Is gravity a renewable energy source

[aspiretoreality]

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.

[airbreather → aspiretoreality]

In the uphill concept, consider gravity as the spring or rubber band that is stretched.
