Out of all the things we've seen in the tech world of late, for some reason the ability to land a rocket on a pad like this just blows my mind. Just...wow.

Interesting stuff. When I left the beverage industry because of COVID the new rage was CO2 refrigerant systems. The were cheap but they were notoriously unreliable and were not field serviceable. The only fix was to swap the piece of equipment out. That sure is not very efficient.

Pretty much any Samsung Appliance these days.

That probably gets you a new refrigerator every year. I believe the problem with CO2 refrigerant is the operating pressures are too much of a challenge for the solder joints and the evaporator coils.

Ad Astra is a fairly good take on this.

That story is a take on the Fermi Paradox,

although the writer / director said he was really going after a Conrad Heart of Darkness story line.

Saw an article about this and "dug" a little deeper. Pretty incredible engineering. If it appears interesting to you the explanatory video is worth the 9 minute watch. https://www.churchofjesuschrist.org/fea ... s?lang=eng

Millau Viaduct, a perfect example of where engineering meets art. Cantilevered high over the Tarn gorge in southern France, and yawning 2,460 meters (8,070 feet) in length, the Millau Viaduct is the world’s tallest bridge, with a structural height of 336.4 meters (1,104 feet).
