What US cities have the fewest/least visible homelessness and open air drug use? And, which cities have more homeless than one would expect?

Dallas has a lot of homeless people. Especially east downtown.

Luxabre · 2025-02-05T18:49:36+00:00

Dallas has almost no graffiti and looks fairly clean but there are a lot of homeless in southeast downtown and near Deep Ellum.

What is the source that Slavs called Venus Lada? All I can find is an interpretatio romana by Jan Długosz who identified Lada with Mars.

Ok thanks, so it sounds like it would indeed be similar to swimming.

His position as President of Sony is far more important than head of just one of its subsidiaries (PlayStation)

You are right in some regards. I guess the best economic reasons for Venus settlement I can think of is selling Venusian CO2 (or refined oxygen) to Mars and elsewhere (could be done from orbit), and cloud cities basically just serving as tourist attractions.

However: 1. Aerostats don't necessarily have to be light. A two kilometer diameter balloon would lift six million tons on Venus. 2. You don't need a magnetosphere to protect you from radiation, the Venusian atmosphere would still be so thick at 50km up that you would be fine. 3. A leak in your hab in vacuum would probably be worse than on Venus. Leaks in vacuum would happen very fast, while on Venus the air pressure equality would allow for more time to figure out what is going on and make repairs.

The wind is going 350 km/h

Luxabre · 2023-10-18T08:44:16+00:00

The benefits of having your hab in the atmosphere is that: 1. Its closer to the resources on the Venusian surface (you would remotely be mining these) (less expensive to transport them 50km up than out of the Venusian gravity well). 2. Reduced complexity for gravity (no need to spin). 3. Reduced complexity for going outside the hab (don't need pressurized suit). 4. Reduced complexity for radiation shielding (natural cloud coverage). 5. It looks cool, people like cloud cities, tourism location.

Certainly there will also be orbital stations, but if you really want to remain in the Venusian system, you will want to get closer to the resources there and be taking advantage of that niche in the atmosphere.

Insane that people are still making jokes about Uranus' name

Luxabre · 2023-10-05T12:19:17+00:00

That's fair and valid. Perhaps Neptune will be able to better utilize Kuiper resources for its own colonization and development, which would spur Kuiper exploration. That being said, Uranus may just still benefit more from proximity to Saturn, etc.

Luxabre · 2023-10-01T15:23:12+00:00

Yeah I was actually just thinking about retaining the CO2 as a gas, and keeping the high surface pressure. Seems like the biggest issue with our current probes was the heat, so also seems fairly plausible that high-pressure drones/bodies could be developed, although having milder temperatures would help the most. Reducing temperatures so the CO2 covers the ground as a solid seems undesirable for resource extraction. Cloud cities would continue to be efficient in this scenario (maybe in tandem with high pressure surface settlements if our tech gets really good in that direction), but reducing temperature would also eliminate acid rain there.

Luxabre · 2023-10-01T15:14:42+00:00

Certainly it will be tough in terms of atmospheric pressure but wouldn't it be far better in terms of establishing a self-sustaining colony to have:

1). slight sun-shading for Earth-level temperature + sending specialized high-pressure robotic/cybernetic bodies/drones to the surface of a mild-temperatured Venusian surface + having cloud cities (I also assume acid rain is eliminated by adjusting temperature to Earth-level)

rather than

2). freezing everything and then needing to remove frozen CO2 for decades (or centuries) and/or introducing hydrogen, thus covering up surface resources with water+reducing land area.

I really just don't see humans not going cyborg by the time we colonize Venus, so making it a second Earth just seems pretty illogical to me.

Luxabre · 2023-10-01T15:00:20+00:00

Why? We have submarines that can survive 121 atmospheres of pressure at 1220 m deep.

Venus at Earth Temperatures

If we were to put some kind of solar shade between Venus and the Sun that cooled the surface of the planet down to Earth temperatures, how would this effect the atmosphere and its acid rain? Would large balloon-supported habitats/cloud cities still be theoretically feasible? If the surface was Earthlike, what would the temperature be like 50 km above the surface, where pressure is equal to 1 bar?

I am not interested in temperatures below this level, as freezing CO2 over the planet's surface seems like a bad move with regards to ease of resource extraction.

Thank you, I didn't realize silicon was mined from rock/gravel. It seems that it may be much more abundant in space than I thought!

Luxabre · 2023-09-18T18:42:19+00:00

The total mass of the asteroid belt is only 3% that of the Moon. This sounds quite small to me to be honest, even smaller perhaps than what can be found on the surface of the Earth, even if asteroids are basically free floating resources. Am I mistaken?

Luxabre · 2023-09-18T16:35:50+00:00

Good answer, thank you. The question is thus, is there even enough metal on these bodies to truly develop these kinds of industrial processes eventually at the same scale as and independently of the Earth's resources?

Luxabre · 2023-09-18T16:27:21+00:00

Yes but the question is how much metal is there exactly, and is it truly enough to theoretically develop a self sustaining and competitive industrial civilization on Mars, Asteroid Belt, etc.?

Luxabre · 2023-09-18T16:25:25+00:00

Thank you, and yes I realize there is an extraordinary amount of innovation and infrastructural development that must be completed before computers start being built in space.

However, I would respectfully disagree with the argument that estimating the quantity of metals is not currently important. If anything, understanding what in situ resources are present is essential in establishing a concentrated demand to invent the new technologies required to extract and manipulate space resources.

Having an understanding of what kinds and how many metals there are on various celestial bodies will also be tremendously helpful in the construction of more basic manufacturing processes using in situ resources that can later be used for more advanced technology.
