https://newatlas.com/energy/quaise-deep-geothermal-millimeter-wave-drill/ Standard crazy nonsense, or viable method? The capital costs are probably crazy, what with amounts to a science-fiction-esque energy beam doing the work, but if it's only a third as effective at drilling as they claim, that's still a little amazing.

in re the capital costs on that, 100 days of supplying a megawatt of energy in each location you're going to install this is probably not going to be cheap minimal in comparison, one assumes, to the energy you'll get back out, but

If they really are going to drill at a fossil power plant, it shouldn’t be to hard to get a wholesale power rates. At that point, $30-80 per MWh is going to give a range of $72,000 to $192,000. Peanuts compared to what it is going to cost to set up the rig and cabling to go so deep.

sure, all of the setup is minimal in comparison to future production, like i said, if it works as intended anyway, it's a wild idea, and it would be awesome if it actually works. unlike actual fusion, i suppose we'll find out in the next five.

There are a ton of decommissioned power plants out there where they keep the switchyard active, there is a lot of existing infrastructure that would have to be changed if they don't usually. Power availability and cost is nothing in the grand scheme. What matters is the condition of the turbine, generator, and GSU. It becomes a lot less appealing to retrofit an old plant when you need to throw $100 million to catch up on the deferred maintenance in fossil plants that have a shutdown date in the next few years.

Power availability and cost is nothing in the grand scheme. I didn’t think about that part of the process. Unless they attempted this at a steam plant that was just shut down, it is pretty safe to assume that anything left of the old generation station is useless junk. Once the generation station stops operations, things fall apart incredibly fast. The turbine bows and becomes useless unless it is kept spinning at all times. Without water in it and maintenance, the boiler starts to rust apart pretty quickly. Even the concrete foundations start heaving and cracking from temperature changes without the constant heat at all times (this is probably location dependent). While it might still be advantageous to use a former generation site to attempt this drilling scheme, it’s probably more due to the fact that there is ample transmission connections available, and the land will be vacant/cheap due to all the toxic crap that leached into the ground. Not because they can just retrofit an old steam unit. There may be a few that are in good enough repair to prototype the system, but that will definitely be the exception.

i think their whole idea is to capture those plants as they're shuttered, not reopen already-closed ones (though i suppose those would also work, equipment condition depending).

Finland will seek to extend the life of the current reactors in Loviisa until 2050. To make them not reliant on russian technology and just because we need them to keep going.

Should be easy to do, thankfully studies are showing Neutron Embrittlement has not been as much of an issue as was predicted, same thing is happening in the US with old reactors.

this is probably better to post in The War thread, but hearing local radio news say "another Chernobyl was adverted" wrt to Russian capturing control of a nuclear power plant is depressing. like it a nanometer of progress is threaten to fallback lightyears because of Putin's tiny dick problems.

It was also overblown. While there was risk to damaging the reactors, it was nowhere near as bad and was unlikely to end up being a Chernobyl event. The firefight was actually the opposite direction of the reactors anyways. Also, the VVER series has a proper containment building which is designed to handle impact of an aircraft, sure a shell could damage it, but you'd need to really try to damage the core enough to cause enough coolant loss for a meltdown, or damage the Emergency Cooling systems generators.

The firefight was actually the opposite direction of the reactors anyways. According to Wikipedia the VVER design doesn’t have the positive void coefficient problems of the RBMK so the worst that would possibly happen is a meltdown. Whilst this would be a nuclear catastrophe, it’s not a power excursion, core explosion, and raging graphite fire. Media loves to use Chernobyl as a benchmark but it really was an inherently dangerous design run in an inherently dangerous fashion under a regime that didn’t tolerate dissension. That’s my take anyway.

And even with all the problems inherent to the design, I remain unconvinced that it would have been run that way if its positive void coefficient was known to the planners and operators. Chernobyl #4 is one of the best examples of the Swiss cheese model we have.

Chernobyl #4 is one of the best examples of the Swiss cheese model we have. Long and sort: Don't let an idiot like Dyatlov convince you to run the reactor recklessly. If you can't get power, turn the reactor off. The entire thing was because they tried to force power out of a stalled reactor by directly doing exactly what you should not do with a reactor, any reactor. Yeah, its a super good example of the human element of the swiss cheese model.

What's the Swiss Cheese model? Because normally in anything involving engineering I'd associate "Swiss" with "intricately engineered to overperfection and quality". I.e watches, chocolates, etc.

CommieGIR posted:or damage the Emergency Cooling systems generators. This was the thing that I was worried about while watching it unfold. I had heard that most of the reactors had already been shut down, and I would assume the rest would be once the firefight broke out. But that means that the power for cooling either came from external sources (the city that some Russian troops had just come thru) or external diesel generators. And I don't know where those generators, or their fuel sources, were in relation to the fighting. Also I doubt that whoever planned the site had an active firefight between large scale forces as a high priority during the facility design.

I had heard that most of the reactors had already been shut down, and I would assume the rest would be once the firefight broke out. The EDGs only need to be run during the cooldown period or while the reactors are active, once the reactor is cold shutdown after 2-3 days, its easier to lose electricity. Ideally, you never want to lose it, but the cooldown period is what is important to cover.

I.e watches, chocolates, etc. Despite being a dense solid block, Swiss cheese has holes. Look at a thin slice of Swiss cheese and there will be holes that allow something to move from one side to another. Now stack it next to another slice and some holes will be blocked, while others may line up. The more slices you add, the less chance there is of something being able to make it through from one side to another. In risk management it's used as an analogy for different layers of protection. Equipment, training, processes, checks, all add an extra layer which while they may have holes are less likely to line up with a hole in all the other layers of protection.

As is the response. A big part of designing appropriate defense in depth for risk management controls is making sure that the blind spots don't overlap too much, and it's a step that's often missed.

The analogy doesn't involve slicing a block, it's taking random slices. And even then the Swiss cheese name is just shorthand for a plane with holes in it rather than intended to be too literal.

ShadowHawk posted:Google Trends shows a very sharp growth in interest in electric and hybrid cars. This is great news. For decades the most popular vehicles have been heavy, luxurious, and gas-guzzling trucks, despite the fairly high upfront sticker prices (the average Ford F-150 sells for $47,000 new, which is more than a Tesla Model 3). I think it’s pretty clear that highly-subsidized gas prices have been discouraging people from particularly valuing gasoline efficiency or exploring greener options. Hopefully this change in consumer spending continues and doesn’t get blunted by Republican attempts to double down on gas subsidies, deregulation, and fuel tax cuts. Creating the conditions for systematic investment in green tech is the surest path forward.
