Indeed. With all of the stuff that we have no clue about there in our solar system, why spend so much time on the second-best studied body on the solar system? I'd take a single Titan-exploring tiltrotor VTOL craft over a hundred new lunar rovers.
"Love" is the nice way to put it. "Largess at the expense of all other solar system exploration" would be more accurate. Here's a graph. And it's always the same stupid justifications - how many times can we pretend to be excited about "revelations" that Mars was once in its past a wet place? Or that we're going to stumble into life any time soon in its perchlorate-rich, destroys-organics-on-contact regolith?
And it's not just huge amounts of money that they're wasting - they're also throwing away most of the remainder of our plutonium supply. At least there's money to start making it again, but it'll take time. Plutonium is precious, and it's needed for outer planet missions.
I hate to be the one to tell you but academia generally pays poorly outside of the US. More so in a country like Russia that is still clawing its way back up from the economic collapse that occurred during the transition from communism to capitalism.
Perhaps if most of the country's wealth wasn't concentrated in the hands of a handful of corrupt oligarchs who live like a modern version of Roman emperors they'd be able to pay researchers a living wage.
You don't need "antigravity" (which in all likelihood is impossible). Diamagnetic hoverboards would be possible... if we could make ridiculously powerful, compact halbach arrays in the board. Also you'd need a clever mechanism to detect and deal with flying over ferromagnetic material, or otherwise it's going to smack into your board really hard.
The problem is, sewage treatment systems have a lot of trouble (at present, let's just simply say "can't") filtering them out. They go into the sewage, they will go into the sea.
Setting up filters for particles as small as 1 micron for all sewage going out into the ocean is obviously going to be a massive expensive. Who wants to pay for that so that people can keep sticking bits of plastic in cosmetics?
Seriously, whose bright idea was it to make bits of plastic, bite-size for plankton, looking like fish eggs, whose very design intent is to wash out into the ocean? And no, while they're not harmful to us, they absolutely will be to plankton - if not immediately (how healthy do you think you'd be if you wolfed down an entire meal-sized chunk of plastic?), then with time. Plastics act as chelators for heavy metals and a number of organic poisons, to such a degree that they might even be economical to mine. There's simply no way that this isn't going to have an impact.
And it's so stupid when one can just use soluble crystals (salts, sugars, etc) instead of plastic.
The article is also based on some terrible reasoning, like:
That means there will be no asteroids left in the Solar System, because they all will have struck Earth, in another few hundred million years. Think someone’s overestimated something there? Yeah, me too. Let’s take a look with the flaws in our fear-based reasoning.
Yeah, in a universe where our solar system is some sort of perfect steady state. Which, of course, it is not. Asteroids collide or - more commonly, come close to other bodies and gravitationally interact - and throw each other into different orbits. When that happens, non-Earth-crossing asteroids can become Earth-crossing ones. For example, one of the candidates for the K-Pg extinction event is a Batisma-family asteroid. This family came from an asteroid breakup 80 million years ago.
A person well versed in the field would be aware of the fact that asteroids are not in some sort of unchanging steady state. Which is why they're the ones paid to do the research on the subject.
And more to the point, we really don't have a good handle on what's out there. We have trouble making out dwarf planets in the outer solar system. We really have no bloody clue what could be on its way into the inner solar system, apart from studying how often major events happen.
And on that note, another flaw in his logic, given that until recently, the vast majority of Tunguska-style events would never even have been detected, having occurred over the oceans, remote deserts, the poles, etc. So by all means it's perfectly fair to say that the fact that an asteroid hitting earth is more likely to hit a remote uninhabited area is perfectly fair. But saying that while mentioning the rarity of inhabited areas having been hit in the past is double-counting. The historical record is evidence of how often they hit populated areas, not how often they hit Earth.
Lastly, his claim that only one person has ever been "hit by an asteroid" is ridiculous. 1500 people were injured by the Chelyabinsk one in 2013 badly enough to seek medical attention. Yes, they weren't "hit by rocks", but that's not what large asteroid impacts do; they mostly or completely vaporize by exploding in the atmosphere and/or on impact. And there's lots of reports throughout history of people getting struck by asteroids; just because they weren't documented by modern medical science doesn't mean it never happened. Seriously, what's the bloody odds that the only person to ever in historical times be hit by an asteroid would be in the 1950s in the middle of a first-world nation? Now what's the odds that someone being hit in the 1950s in the middle of a first-world nation would be well documented, publicized, and believed?
Just a lot of really bad arguments.
Can you imagine the dystopian dictatorship where trekkies come to power? All of the halls of power full of people walking around in spandex and fake ears and brow ridges, the fed directed to work toward the absolution of currency, the military directed to accelerate development of phasers and for all recruits to undergo "Kobayashi Maru" training.... NASA would finally get their proposed $18,5 billion dollar annual budget passed - except that the bill would have the word "annual" crossed out and the word "monthly" written in its place. National anti-bullying legislation would be passed, probably with a name like Spock's Law. And of course they'd insist on referring to the UN as the United Federation of Planets.
Seriously though, I don't see the level of cooperation required for this project persisting long enough to pull it off.
Of course given history, there will be disruptions, but it'll work out in the end. They are easily startled - but they'll be back, and in greater numbers.
Interestingly, Google still has 288 hits on this decades-old and decades-unused email adress.
LEDs have lifespans of what, 50-100k hours? So maybe a couple decades. And some will significantly outlive their design life, as is always the case with failure curves. The solar cells should be good for decades, until the contacts corrode.
One *could* design devices to last for thousands of years. But that's not usually a design constraint
There's no guarantee that ECCS are independent and can operate in the vent of station blackout. The HPCI used in Fukishima, for example, is a steam turbine-driven pump but not a generator, and it has electrical components that require operation. Which is why it didn't prevent meltdown.
The primary turbines are not designed to operate on the amount of power generated from decay heat alone.
Small upgrades, this already happens.
Large upgrades, by phasing out old units and building new ones. The complex as a whole remains.
Taking down an old unit is BTW a very large task ("decommissioning"), can take decades and comes at extreme expense. Which is part of why plant operators try to keep their old units going as long as possible, even when they've become expensive to operate.
Could you, so that we know where you're coming from, elaborate on where renewables "dont cut it"?
These "some environmental groups" include the governor of New York, who is trying to get the plant permanently shut down.
It's not fringe radicals who think it's a bad idea to have a nuclear plant right next to the largest population center in the United States.
Right, because generators the size needed to operate nuclear power plants are the sort of thing that you just pick up at any corner hardware store and "drive up and plug in"?
here's what one of those generators looks like. A nuclear power power plant may have a dozen or more in their generator building. Even replacing just one is not some sort of couple day task. These things take prep work and a lot of labour to acquire, move, install and set up. Weeks to months. That's all assuming that the generator building itself is still usable; a failure in such a large generator, or the sort of external event that can take out such a large generator, is not exactly some sort of low energy event.
Back before Fukushima people like you were all over Slashdot harping about how major nuclear disasters couldn't happen again, that it's only possible with old Soviet designs like Chernobyl that are horribly misused. Quit being so damned short sighted. Unforseen events and cascading failures do happen. You can't just act like "the list of causes of major that have already happened is the entire comprehensive list of what could cause major failures".
If you scram, lose your grid connection and lose your generators, you will likely get a Fukushima-like event. Two of the three happened here. Let's not pretend that the concept of something taking out the generator room, or otherwise preventing its power from working the pumps - generators which are only rarely tested - is such a preposterous concept. And let's not be silly and act like massive pieces of industrial equipment can just be plopped down and hooked up like a little Honda generator.
