> In fact, the fly ash emitted by a power plant—a by-product from burning coal for electricity—carries into the surrounding environment 100 times more radiation than a nuclear power plant producing the same amount of energy.
> In a 1978 paper for Science, J. P. McBride at Oak Ridge National Laboratory (ORNL) and his colleagues looked at the uranium and thorium content of fly ash from coal-fired power plants in Tennessee and Alabama. To answer the question of just how harmful leaching could be, the scientists estimated radiation exposure around the coal plants and compared it with exposure levels around boiling-water reactor and pressurized-water nuclear power plants.
> The result: estimated radiation doses ingested by people living near the coal plants were equal to or higher than doses for people living around the nuclear facilities. At one extreme, the scientists estimated fly ash radiation in individuals' bones at around 18 millirems (thousandths of a rem, a unit for measuring doses of ionizing radiation) a year. Doses for the two nuclear plants, by contrast, ranged from between three and six millirems for the same period. And when all food was grown in the area, radiation doses were 50 to 200 percent higher around the coal plants.
Definitely doable. But then there's no longer any special appeal to living on Mars, as opposed to: living in rotating space habitats among the asteroids.
If we reformulate Musk's goal as being: "Create off-site backups of human civilization", then I think asteroid mining & space habitats have a better shot at bootstrapping this process than colonizing Mars.
Once we are leveled up this way in resources and technology, building settlements on Mars can be a side-effect of this outcome. Just like the burgeoning scientific outposts on Antarctica are a side-effect of our current civilization.

Short Thread: staying with some friends and last night after everyone went to bed I could not figure out how to turn off the large ceiling light in their living room. There is a wall controller that seemed fairly straightforward.
There is a large main light, a smaller light on top that faces up, several levels of brightness, and a fan. Each time I tried to turn off the upward facing light, something else would turn on. After ten minutes, I woke up my wife to ask her to help. It only got worse.
Each time we thought everything was off, a few seconds later something else (or everything else) would turn back on. Minute twenty, I started laughing out of sheer frustration at what felt like a Myst puzzle. Couldn’t wake our friends cause they have a small kid.
Suddenly, we solved it. Everything went off and stayed off and after waiting a full minute we realized it was gonna stay that way. This is circa 1am. I finally went to sleep.
This morning we asked about what the deal was with the light. The answer has broken me.
Our friends are in a newly built condo complex. The fan controls use a binary code to connect to the fans. Additionally the controls were only supposed to have a signal reach of 30 feet. They reach much, much further.
There are almost 40 units within reach. Based on the binary code limitation there’s only 16 possible code options. So everyone in this building controls the main light and fan of at least one other person; maybe more.
From 12:30 to 1am last night, I was engaged in a proxy war with up to three other apartments, as they in turn, set my fan to high and my lights to the brightest setting, until everyone gave up.
Our hosts have been here for six months and have found a way to live with it by imagining who in their building they might be interacting with. This one guy who they think particularly might be an asshole and they have suspicions about when he’s running the show.
I am staying here again tonight. I look forward to wrestling control of the lights from what is essentially angry ghosts in my own personal AITA post.
My inclination is to go Full Lawful Good and turn off everyone’s lights tonight at 10pm to make sure we all get a good night of sleep and wake up rested and ready for a productive Saturday.
The light is off. War is over.
These are fair questions. Where are they not tolerated? And by whom?
I beg your pardon?
Who exactly is holding a gun to humanity's head?
Are you thinking of entire populations or do you have specific individuals in mind?
And what does your plan look like?
HRC's secret email server and the leaked Kash Patel emails couldn't be more different.
The first one is, in the words of a federal District of Columbia judge: "one of the gravest modern offenses to government transparency". [1]
The second one is the malicious leaking of some private emails. These emails are frankly none of our business (unless you are part of Kash Patel's family or friends).
