And you can’t disrupt the meeting by interrupting the prayer until they kick you out, because then presumably your employer would fire you, I assume? 'Cause if not, you should definitely ruin their motherfucking christofascist bullshit.
Maybe read the article? It’s talking about a new kind of sail that’s literally a giant kite attached at the end of a line and kept flying hundreds of feet in the air above the ship by computer control. Not a spinnaker or kite sail; something closer to a parafoil.
That’s why this is different and they aren’t talking about going back to fully-rigged sailing ships.
(Actually, who are we kidding? They couldn’t care less how hard and dangerous the work was. The real reason they like this new design because it doesn’t have masts to get in the way of loading cargo.)
400% efficiency is good, but it’s not better than the ∞% efficiency you get from something that doesn’t require fuel input to begin with. (I’m pretty sure the Technology Connections guy would agree on that point.)
If nothing else, think of it this way: even if you still want to use air conditioning to make sure you get all the way down to comfortable room temperature or whatever your target is (which a Qanat, although able to achieve a >15°C ΔT, might or might not be able to do reliably), it’ll still give you a big head start and greatly reduce the amount of energy needed. It’s a lot like using a ground-source heat pump instead of an air-source one. What’s not to like‽
Obviously, you use the tech in the situations it’s appropriate for. If your office building happens to be in Phoenix, AZ, then a qanat might be a pretty good idea!
Frankly, ceasing to design homes and factories that way was a mistake. Stack effect ventilation is no less of an important part of green building technology today than it ever was.
Wikipedia claims “greater than 15 °C.” Besides, even if you supplement it with air conditioning, that’s 15 °C less ΔT worth of electricity you have to pay for.
Modern plumbing uses pressurized pipes that are completely full of water, and can thus flow uphill, as long as the elevation gain doesn’t exceed the head pressure from the water tower or pumps. That makes such pipe systems relatively cheap and easy to build.
In contrast, qanats require large conduits with space above for the air to flow through, using open channel flow. That means the entire system needs to be designed with a gentle downhill monotonic slope. That’s doable (the wastewater and stormwater sewer systems are designed that way, for example), but it’s more expensive and would require a lot of re-work if you wanted to convert over the existing water distribution system.
This type of sexism is doubly stupid. At least in my experience, women in male-dominated fields tend to be exceptionally good at what they do because the ones that aren't passionate about the work don't find it to be worth staying because of the sexism. If I were going to be biased, I'd be biased in favor of having a woman work on my car!

There have been screenshots of pro-admin/anti-mod comments that were clearly written by chatGPT (e.g. including the "as a neural network" or whatever boilerplate). They could be fakes or false flags, but it wouldn't surprise me if they were real.
The "Lemmy is too complicated" part I can believe is organic from normie Redittors, though.
