  • I think the article author is completely confused and doesn’t understand what’s happening. There are hints of what’s happening in this paragraph.

    Fresh water—or treated wastewater—is placed on one side of a membrane. On the other side is seawater, made even saltier by concentrating leftover brine from a desalination process. The difference in saltiness pulls the fresh water across the membrane, increasing the pressure on the saltwater side. That pressure is then used to drive a turbine, generating electricity.

    I don’t think any fresh water is being used. I think what’s actually happening is…

    Very salty wastewater (from the desalinization plant) is placed on one side of a membrane. On the other side is seawater. The difference in saltiness pulls the wastewater across the membrane, increasing the pressure on the saltwater side (or maybe the other way around). That pressure is then used to drive a turbine, generating electricity. The waste then is just water that’s saltier than sea water, but less salty than what came from the desalinization plant.




















  • Please allow me this opportunity to jump in and complain about the minority, but not insignificant number, of people that don’t seem to be aware that that is even an option (just taking your foot off of the gas/accelerator to slowly decelerate).

    Every couple weeks or so I seem to find myself behind someone that’s always either accelerating, or braking, with the brake lights repeatedly flashing on momentarily for no apparent reason. It’s like they realize that they’re going just a little faster than they want, and definitely don’t want to accelerate any more, so the only thing they know to do is hit the brake, instead of just taking their foot off of the accelerator. So they’ve hit the brake and now they’re going too slow, so foot moves off the brake and back to the accelerator. Rinse, lather, repeat.

    End rant. Thank you for this opportunity to vent.
