A Call For Humor!

Actually, it was the original Expedit, not the Kallax -- although they may do it, too.
I was multi-tasking at the time I posted.

The horizontal shelves are one piece, the vertical ones are not -- but the shelf units are square, so they can be assembled 90 degrees out of phase, as it were.
Laden with LPs, the lives of the misassembled shelves are nasty, brutish, and short.

Well, when I build my DIY record shelves I used 38 mm spruce for the verticals and 19 mm spruce for the horizontals and the back side. Very stable. I'd never trust the Kallax to bear serious weight due to its hollow material.

Really? They expect THIS to supply a significant portion of San Diego’s drinking water? … By 2035, when they finally figure out how to open the valves?

Disclaimer: it was 1 of 3 pictures from the WSJ, but that’s how they arranged the legend! :)

I’m no Chemical Engineer, but that’s an Oxygen line and I’m guessing that under pressure it could pass a fair amount of O2 to inject into a water stream to use as a purifying agent.

Though I know that water aerators kill microbes by exposing the beasties to oxygen in the air, I’d intuit that injecting pure oxygen into a water stream would be more effective than mere air, albeit probably more expensive.

Add additional lines and water streams and this probably scales effectively.

Any ASR Chem Es who know water purification who might want to chime in?

Yup. Killing microbes and removing several types of nasty contaminants that will bind to the oxygen and fall out as solids.
