Among the dreams of mars trips and a space elevator, which continue to sucker people and are nothing but perpetual-motion-level idiocy,

Like man flying; you're the idiot. I will say it bothers me when people still talk about a space elevator, when a space catapult or Lofstrom Loop is a more more realizable engineering endeavor. Zubrin designed a Mars space mission back in the 1980's; its thoroughly plausible to attempt, even limiting the project to 1980's technology.

a moon colony is something that will happen.

Not necessarily, because a permanent colony is a stupid thing to attempt. Its stupid because its not economically sustainable if it requires Earth support to exist. Until scientists determine there are vast pockets of Moon ice, or an exploitable economic good, like He3 or "valuable" metals in Moon craters, a Moonbase is not self-sustainable or economically worth it for a government to attempt.

Regardless of other reasoning or misgivings, the ability to start and maintain any presence on the moon is the first step to an interplanetary mission with humans.

Its a waste of money. Its like requiring a colony on the Azores before attempting to find a continent exploring the western sea.. If the project could dismantle the Moon colony as soon as it reaches its first year of sustained existence, then it wouldn't be economically damaging to a Mars attempt, which would be much more rewarding from an engineering standpoint.

Enigma2175 explained things pretty well. Try Googling "rods from god" or "project thor" or start here, https://en.wikipedia.org/wiki/... to quote,

The typical depiction of the tactic is of a satellite containing a magazine of tungsten rods and a directional thrust system. (In science fiction, the weapon is often depicted as being launched from a spaceship, instead of a satellite). When a strike is ordered, the launch vehicle would brake[1] one of the rods out of its orbit and into a suborbital trajectory that intersects the target. As the rod approaches periapsis and the target due to gravity, it picks up immense speed until it begins decelerating in the atmosphere and reaches terminal velocity shortly before impact. The rods would typically be shaped to minimize air resistance and maximize terminal velocity.

Though it does seem the original idea was closer to telephone pole size.

The problem with expecting the tax load to fall on everyone but the very wealthiest, is that when that idea has been tried, it ended in a succession of wars: here's an example.
One of the revolutionary demands was equality before the law, as in many monarchies in Europe the nobility were the only ones electing the legislature, and paid no tax. Bloodshed ensued.

And even if you manage to accelerate the crowbar enough to drop straight down, it would vaporize before it hit the ground.

Not necessarily, particularly since you wouldn't want to drop it straight down. You get to choose the entry trajectory and the trajectory that uses the least delta-v also has the best profile for entry (dropping the perigee just low enough that the rod re-enters). A steel rod has a good ballistic coefficient so it won't heat nearly as much as most of the objects that enter the atmosphere (space vehicles, asteroids, etc.). And even if part of the rod ablates away as long as a decent portion still strikes the target the weapon would be effective, there isn't a ton of difference between getting hit with 20 KG of steel at orbital velocities vs. 15 KG of molten steel and 5 KG of white-hot iron plasma.

Smart. If you don't want outside entities are eroding your country's autonomy

44% of Indian children are malnourished. 72% of Indian infants are anemic.

So not so "smart".

Malnutrition in India

In China, the number of malnourished children is negligible. They are welcoming to foreign investment, and have done it without "eroding the country's autonomy".

30 years ago, China and India chose dramatically different paths. It is now obvious which turned the wrong direction. Economic isolation doesn't work.

There are no barriers to better budgeting.

You need to read Boots theory of socio-economic unfairness to understand why I think you are mistaken in your point of view.

The reason that the rich were so rich, Vimes reasoned, was because they managed to spend less money.
Take boots, for example. He earned thirty-eight dollars a month plus allowances. A really good pair of leather boots cost fifty dollars. But an affordable pair of boots, which were sort of OK for a season or two and then leaked like hell when the cardboard gave out, cost about ten dollars. Those were the kind of boots Vimes always bought, and wore until the soles were so thin that he could tell where he was in Ankh-Morpork on a foggy night by the feel of the cobbles.

But the thing was that good boots lasted for years and years. A man who could afford fifty dollars had a pair of boots that'd still be keeping his feet dry in ten years' time, while the poor man who could only afford cheap boots would have spent a hundred dollars on boots in the same time and would still have wet feet.

This was the Captain Samuel Vimes 'Boots' theory of socioeconomic unfairness.

The exclusion zone is actually 2600 km^2, or 1000 mi^2. Someone at the BBC who has no business writing anything with numbers apparently read that as miles (not mi^2), and converted to 4184 km, which he rounded down to 4000 km^2.

A 30 km evacuation radius yields a 2827 km^2 circle. So pretty close to 2600 km^2.

The design of the plant at Chernobyl used a positive void coefficient. Basically, when the cooling water starts to boil (creating voids in the water), that increases the rate of nuclear fission. No western nuclear plant was ever designed like this because of how stupidly dangerous it is. All western nuclear plants use a negative void coefficient - the cooling water boiling slows down the rate of fission. An accident like Chernobyl could never happen at a western plant. The Soviets were trying to get energy for as cheap as possible and cut all sorts of corners designing their plants, including using a positive void coefficient .

Chernobyl began as a test where they intentionally shut down the automatic safety systems, then didn't react in time when the rate of fissioning began to go out of control. Due to the positive void coefficient design, once the boiling water began boiling, the heat generation began to increase exponentially. The fuel vaporized and exploded, blowing the reactor and containment building apart, and throwing radioactive debris and vapor into the atmosphere and countryside.

The accident at Three Mile Island was actually pretty similar in terms of buildup. They shut down a bunch of safety systems for a test, then didn't monitor the instrument readings closely enough (or more likely, the people monitoring them weren't trained well enough to understand what the readings meant - Homer Simpson as incompetent nuclear plant operator is actually a reference to TMI). The temperature went up, the cooling water boiled, and the fissioning stopped. The increased temperature was enough to melt the fuel rods, turning the reactor into useless slag. But it was all contained within the steel pressure vessel exactly like designed (there's a second reinforced concrete containment vessel around the pressure vessel in case it fails). The concern at the time was that a reaction between the fuel rod cladding and water had created hydrogen gas at sufficient pressure to crack both containment vessels, so they evacuated around the plant out of an abundance of \caution. But it turned out not to have been a concern as the hydrogen vented. It's a tiny molecule so can permeate through things that are designed to contain water and radioactive materials. (It's the reason the buildings at Fukushima blew apart. There's supposed to be a vent or fan which exhausts hydrogen into the atmosphere, but apparently that wasn't working at Fukushima so it built up until it reacted with atmospheric oxygen in an explosion that blew apart the exterior building. It did not affect the pressure vessel or the concrete containment vessel.)

The comparison I like to draw when people point to Chernobyl as an example of problems with nuclear power is Banqio. The worst power generation-related accident in history was actually the failure of a series of hydroelectric dams. During intense rain, a series of earthen dams used to hold water for generation at a hydroelectric power plant failed. The resulting flood and devastation killed about 170,000 people, destroyed nearly 6 million buildings, and left 11 million people homeless. But no western country uses earthen dams for hydroelectric power. So citing Banqio as an example of why hydroelectric power is dangerous and shouldn't be used, is like citing Chernobyl as an example of why nuclear power is dangerous and shouldn't be used. They're both irrelevant outside of the Communist bloc, since the rest of the world never did anything so stupidly dangerous.

There are about 240 million 911 calls each year. There are about 900,000 sworn police officers nationwide. That's about 266 calls annually per police officer. Given there are about 240 work days per year (5 per week, 2 weeks vacation, 2 weeks of holidays), that's a little more than 1 call per day. There were about 10,550,000 arrests in 2017, or about 1 per month per police officer. So they're responding to about 22 more dispatches (from 911) than they are arresting. What are the odds your average police officer will only arrest things he sees happening on the street, and not any from the 22 dispatches per month?

No one realized that those parts of the airplanes weren't as important to protect because the planes still returned though they were hit there. Protecting the parts where the returning planes didn't get hit was much more important, as obviously, planes hit there never made it back.

I've been on my own GABA influencer journey and wanted to mention an already easy to get substance, at least outside of Russia where it is a prescription only substance, that I'm 99% sure many people take already with great effect. And that it also focuses on the same GABA alpha receptors like they mention targeting in the paper, though the paper's substance is attempting to be selective about where they trigger things. Most GABA alpha items are used for anxiety, at least when given out by prescription. GABA itself is a relaxing/calming neurotransmitter.

Phenibut is pretty cheap, seemingly safe at high doses (yes people take WAY more than the typical prescription dose used in Russia for fun), and the way people talk about it I think it can have some of the same effects as the goal of this new substance when used in moderation. Phenibut doesn't only affect GABA, but seems to release a bit of Dopamine too...the reward chemical.

For a more global GABA increaser for the brain...Inositol. Taking GABA won't get into your brain because it doesn't pass through the blood brain barrier easily. Inositol definitely calms me initially, and makes me more ready for sleep. It was originally misclassified as a B vitamin, and is generally safe up to really huge doses. I've read 6-12g/day is a typical dose for anxiety. I can't seem to stomach more than a gram a day, and I'm getting lots of nausea and other side effects. So not my "magic bullet" solution. But it's another cheap, safe option for GABA manipulation/influence.

I'm not advocating anything here. Please research anything you put in your body. And yes, you can hurt yourself if you take too much phenibut. Or if you take too much for too long, your body will start to downregulate those receptors and you won't get the same effects. And stopping suddenly will be VERY uncomfortable from what I read.

But many people already use GABA beta substances daily (alcohol). The alpha vs. beta refer to a fast vs. slow change substance, as I've understood it. The alpha receptor is designed to react quickly to changing levels of triggers (agonists). The beta, much more slowly. Hence how large a dose of alcohol we need before we can feel it (comparatively), compared to a pill like typical benzodiazepines.

And one of the reasons healthy eating helps calm us is the probiotic organisms we'd be encouraging create GABA in our guts for us. Those eat fiber and other things, are killed off by alcohol, and generate GABA and many other helpful substances we cannot. This is one of the reasons that changes in gut flora is so scary/bad for many people.

For those curious to read more...Google it, :D. There are tons of articles and reddit posts on experiences, and safe places to order from. Below is a wikipedia article on the two GABA receptor types as I'm sure I'm not explaining it all well.

You can't point at the cleanup costs, any more than you can point out how cheap it is for a dude to dig coal out of the ground and burn it or someone who just randomly put a wind turbine on his house and now claims to get free electricity.

The best method we have is levelised cost of energy. I don't know if LCOE for nuclear includes cleanup costs - I would guess not as it's rare that they need to deal with it, but as you note it might not be that much anyway.

The most interesting thing though is the LCOE of renewables continues to fall, while nuclear seems to be pretty steady in terms of cost.

Note: I'm not super opposed to nuclear. But I prefer the idea of small, more decentralised power generation + smart grid. Ultimately though most of what I read in LCOE terms seems to indicate that nuclear is just more expensive. (You can make the argument that nuclear is expensive because of regulatory pain, which is fair - but doesn't really help much. Expensive is expensive! )
