It's a community of hackers passionate about the way things work. Picking it apart helps everyone understand the inputs and outputs of a system to understand how feasible it is, and what the tradeoffs are. What would you prefer, a generic "that's nice"?

As far as I can tell, the author just kinda glossed over the brine situation. Some minerals can be sold, but his solution for the excess salt was just to turbulently mix it back into the ocean, if I'm reading correctly. The sibling comments here explain why that isn't trivial (cost and wildlife impacts). I found them illuminating!

He addresses brine, but not the waste products that come from brine, and only addresses it in one sentence:

> The resulting depleted brine is piped back to the ocean where it is thoroughly mixed with sea water and discharged.

This is not nearly as easy as this sentence implies.

They provide some detailed and constructive thoughts. What exactly does your comment provide? Some sort of complaint which could be solved by yourself by not going into the comments or not reading theirs, hope this helps you in the future.
