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 electrical grids in western Europe. [1]…
> Synthesizing h2 from methane is also done by electrolysis Most hydrogen is currently synthesized from steam reforming of methane [1], not electrolysis. [1]…
>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 unwarranted, instead of investing in renewables.…
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]…
> 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, and by some estimates their indirect…
> 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][2]. Peak demand is normally in the…
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 mean that geothermal power plants can…
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-800. They also have another sodium…
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 as breeder reactors. [1]…
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 Realtek devs wrote and upstreamed rtw88[1]…
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 and 1 planned) [1] rather than…
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 and ignoring all of the reports of…
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 mount options be changed whenever there is…
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 until you change the mount options so that…
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 of nuclear engineers, scientists, and…
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 Laboratory: > In the first test, with…
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 read suggests this is essentially…
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 potential future reactors designs (e.g.…
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 3.2 Gen 1x1" and "USB 3.1 Gen 1" was…
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 ideally a unikernel like OSv could provide…
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 set of systems governed by the laws of…
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 quite the opposite of what you are…
