This is the coolest thing you’ll see today…or for quite a while.

I know where the dead trees and leaves are stacked up. If only someone, I’m looking at you Harris County, would come get them.

The Titan sub implosion hearing is underway, and there’s new information that has been released to the public. It seems that the failure point wasn’t the carbon fiber hull itself, but the join of the hull to the titanium ring onto which the forward dome was attached.

From newly released footage of the wreck (see vid below), the forward dome separated and was found intact, while the entire contents of the interior - including the occupants - imploded into the aft dome.

Wasn’t that always the suspected cause: the connection between disparate materials?

That’s always been high on the list of possibilities. In fact, joining carbon fiber / resin to titanium is particularly problematic and is generally viewed as “forbidden” in design. Stockton Rush is recorded bragging how he used the “forbidden” design because he was such a badass rule-breaker.

Fuck that piece of shit.

His arrogance sunk his efforts eventually :man_shrugging:t3:

Not his alone, unfortunately.

Sorta is, he fired anyone that dared to disagree with him.

I was referring to his arrogance sinking his passengers efforts to continue to live.

To me, the only truly sympathetic character on that voyage was the kid who went only to appease his Dad.

The resulting water probably has trackers added to it. No way I’m drinking that.

Part of the problem with desalination, anywhere, but especially away from the ocean, is what to do with all of the concentrated salt water it produces. Brine disposal isn’t as easy as you might think.

What is this liters/day bullshit. These are American engineers at an American test site. Seems like Texifornia is educated in this, but what is general potable gallons per intake gallons for brackish water?

True, but as energy gets cheaper and cheaper, that task gets easier and easier. It’s just a mixing/dilution issue, correct?

If you’re in the desert like that guy is just dump that shit on the ground what are we a bunch of ecofreaks around here.

It depends on the concentration and the technology used. For reverse osmosis, you typically get 25-30% freshwater and 70-75% waste. Electrodialysis is a bit more efficient, and with brackish water it may be also. But you’re still looking at probably at least 50% of your total volume being waste you have to manage.
