I once read an article which was about how we are willing to spend thousands to save one particular dog, or one particular injured bird, instead of donating that money to "animal habitat preservation" or something similar which will save thousands of diverse animals. And then there's the whole industrial farm-animal raising thing, where billions of animals are systematically tortured. But nobody cares, because it's n…

Just because the act is irrational or sub-optimal does not mean it is insincere. In many respects, the "rational" response would be to shoot the dogs with a rifle and donate the rescue funds to an animal shelter.

There's an entire episode of the HBO Chernobyl TV series dedicated to the decision to kill the animals in the area, rather than trying to rescue them. Yes, many of the animals would have been radiation hazards, or already doomed to death, simply because of their proximity to the reactor explosion and absorption/consumption of radionuclides over time, but the same can be said for the people living and working in area. The decision to destroy all of them rather than trying to work out which ones could be safely rescued saved the resources it would have taken to make the determination and do the rescues. Those resources were probably better used to mitigate the enormous hazards associated with the destroyed reactor.

In this case, there may be an argument that the resources directed towards rescuing the dogs could be better put towards mitigating the hazards of volcanic eruptions in general, but I wouldn't and won't be the one to make that call.

What a wildly toxic reply. Are you really insinuating that people are saving poor trapped animals due to some selfish motivation? Is this how you see the world? If so, I'd rather be what you call "Naive".

It's worse. There's a whole industry on Facebook/YouTube of people who "save dogs stuck in cement" which they put into that situation, and the videos get tens of millions of views. https://www.four-paws.org/our-stories/publications-guides/fa... https://dogtime.com/advocacy/79431-fake-dog-rescue-videos

While the situation is sad, it makes me incredibly happy there are people who worry this much about another living being.

Whenever I hear about tech helping save lives it always fills me with joy to think about all the effort that went in to building this tech, to all the people who involuntarily helped make that tech become a reality.

They should drop a trap with food if the dogs are still ambulatory. Avoids having to hover and make multiple trap attempts, and risk running out of power in flight. It's also easier to pick up a trap with a dog in it than trap a dog terrified of the giant buzzing thing above them. And it ensures they don't half-net a dog only to have it fall out en-route.

> than trap a dog terrified of the giant buzzing thing above them.

That's what the food drops are for. Once they associate the drones with food they shouldn't be very scared of them.

Helicopters cannot handle the potential heat. Drones have issues with payload and control. This is an Ironman situation. Someone call Yves Rossy.

Seriously. This looks like an opportunity for one of the many jet/wingsuit contraptions that have appeared in recent years. Does anyone have a number for that guy spotted over LAX?

I think the 4minutes will be very hard. But since the limiting factor is the battery and the dog probably not cooperating, why not first fly a solar panel (to charge the drone) or an unpowered trap (to give enough time to catch the dog) to allow to rerisk the limitations…

Good idea. I'm not sure why drone charging stations with auto landing pads aren't a commerically sold product yet. I've seen a lot of implementations in masters theses and stuff. If your robot vaccum can do it, your drone can do it.

steerable dirigible, like the goodyear blimp, with suspended cable and basket?

It would crash. A dirigible requires a temperature difference between the ambient (surrounding) air and the air inside the lift bladder. Or the same temperature but different density. The heat of the lava would create an area of lower air density which would result in a significant loss of lift as it crosses. I guess you could compensate with a high altitude crossing, but it still sounds dangerous.

This situation was covered in season 3 of Avatar The Last Airbender, and that is exactly what happened. Such a great show.

The Yves Rossy jet-powered wingsuits seem to be always air launched, i.e. they get airborne out of another aircraft. There is no ground launch.

You might be thinking this kind of "jet pack" contraption:

And I'm not saying that those are "safe" exactly, but flying them at low altitude over hot lava would be a whole new risk.
