Here is a white paper released by Fervo that describes what they've done in more detail: https://eartharxiv.org/repository/view/5704/

I think carbon-intensity (gCO2eq/kWh) is a much more important metric than the use of specific generating technologies. Looking at the data [1], Germany has one of the dirtiest ele…

> Synthesizing h2 from methane is also done by electrolysis Most hydrogen is currently synthesized from steam reforming of methane [1], not electrolysis. [1] https://www.energy.gov…

>This shows that Nuclear power might actually be a hindrance towards an electrified future, as governments have historically put to much faith in it, which was ultimately unwarrant…

Yes, for example Switzerland uses two of their nuclear power plants for district heating [1][2]. China has also started using it for district heating in Haiyang [3]. [1] https://en…

> Nuclear power plants are not "carbon free." They have significant operational needs (indirect emissions), making them of the most expensive sources of electricity available today…

> Demand is usually the highest when PV output is also the highest Not quite, the mismatch in timing between solar generation and energy demand has been called the "duck curve" [1]…

Current geothermal technology requires very favorable geological conditions which significantly limits where it can be deployed. If EGS turns out to be both safe and viable it will…

There's no evidence that they are being used to breed plutonium. In fact the BN-800 burns a mixture of uranium and plutonium to reduce their weapons stockpile.

> the economics for fast reactors have never worked (not even in Russia or China) Russia currently has two sodium-cooled fast reactors that are producing power, the BN-600 and BN-8…

From what I've read[1] it looks like we should be able to use nuclear fission for a significant amount of time (>1000 years). This would involve using uranium and thorium as well a…

Realtek does contribute directly to the kernel, but I think it depends on which internal team is handling the device support. For their PCIe 802.11ac and 802.11ax wifi cards Realte…

It does not appear that this particular electricity shortage is caused by moving away from fossil fuels. The coal plant shutdowns mentioned in the article were outages (2 unplanned…

I think Dell and HP offer somewhat comparable sites. Dell: https://www.dell.com/en-us/shop/partsforyourdell/index HP: https://partsurfer.hp.com/search.aspx

Why did you omit the response you received from a netty developer that showed a large performance improvement[1]? Focusing entirely on the few cases where people report regressions…

I think we are in agreement. I was responding to the comment that stated "BTRFS delivers „classic“ RAID1 and more/better.", which is what I am disagreeing with. Requiring that moun…

I would argue btrfs does not deliver "classic" RAID1. Last I checked if you lose 1 disk in a 2 disk btrfs RAID1 setup and then reboot, it will be unable to mount the filesystem unt…

How could someone demonstrate the safety of these systems if their very association with those systems is a sufficient reason for you to doubt them? If the research and experiments…

With modern reactor designs the inherent safety mechanisms mean that humans are not in the loop to reduce reactivity or remove decay heat. Here's an example from Argonne National L…

What's a scenario where passive safety systems, say those of a HTGR with TRISO fuel, fail and cause it to go prompt critical? I'm genuinely curious about this, as everything I've r…

Why is the runaway scenario unavoidable for nuclear fission? Pressurized water reactors for example have negative void and temperature coefficients, and from what I've read about p…

I thought it went: USB 3.0 (5Gbps) == USB 3.1 Gen 1 == USB 3.2 1x1, and USB 3.1 Gen 2 (10Gbps) == USB Gen 3.2 2x1. Yet the article states: >Accordingly "USB 3.1 Gen 2" became "USB …

Here's a post from one of the OSv developers on performance compared to Linux in 2020 [1]. It paints quite a different picture compared to those benchmarks from 2013. > While ideal…

I was thinking of Copenhagen Atomics' Waste Burner design where they describe their passive walk-away safety features as "Prime minister safety" [1]. > The CA Waste Burner has a se…

My understanding is that these reactors are designed to have a lot of passive safety features (e.g. if all operators walk away the reactor will cool itself and go sub-critical), so…
