This is a pretty blatant case of greenwashing one of the most destructive financial firms on the face of the planet. Even if this system is utterly ridiculous in terms of cost/benefit, Goldman Sachs is a company that can afford to experiment with it in an effort to appear less evil.

- fiatmoney 12y agoWhy would they need to flush the water? If they did, and it's not coming into contact with any major contaminants, why couldn't it go more or less directly back into the water supply after maybe a trip through a treatment centre? For that matter, wouldn't it be even more efficient to use something like seawater? They are on an island after all.
- msandford 12y agoThere's no reason it needs to. If you put some copper sulfate in the water it will keep the microbes at bay and allow you to re-use the water either indefinitely or very good approximation. You could also make a strong brine which would prevent microbial activity and also lower the freezing and melting point allowing you to move more heat with less water on the air conditioning side. It might make your chillers for making ice less efficient, though.
