Thats actually quite substantial considering how big a roof can be, but it will be interesting to see how this scales up.
that equation would certainly look very different in drier areas.
I think this would only really be relevant in drier areas. Areas where you can just to catchment don’t need to worry about this.

Not entirely sure what you meant by this, but if you mean only dry areas benefit from this, I’m not sure. Most of the world is losing groundwater. Capturing any, especially in sub/urban areas might have a measurable impact.

I live in the Midwest and would love free water for my garden
