Fresh PWR fuel is ~4% U-235 and the rest is non-fissile uranium/cladding. ~95% of the potential energy still locked in the "waste" after spending ~2 years in the reactor. Breeder reactors would mean converting greater fraction of this mass into usable energy.

Running PWR core has be at +150 Bar to have +300*C outlet temp - so if something goes wrong it goes wrong like Fukushima. The fuel can stay in the core only until economics say running the plant at less than 100% design power isn't profitable. Every 18/24 months the plant is needs to shutdown for maintance few a weeks to months. I don't like PWRs.

"regular, i.e. non-breeder" MSRs that would just use uranium would be a massive improvement - both in safety and efficiency. Heat a massive silo of (secondary coolant) salt to +500*C with MSR, do the reactor repairs while this reserve runs the turbines, resume MSR. The issue is - politics, fear, and too little research in handling molten salts.

You should look at mitochondria:

  • The power plant of the cell.
  • Runs on a proton-gradient.
  • ATP synthase is essentially a molecular turbine and a generator.
  • oh. a turbine. Damm thing spins ~18000 rpm at medium throttle, pumping out elec- ATP. ATP.

Oops.. it's turbines all the way down.

The scientists didn't joke about that tokamaks will be a great neutron factory/highest neutron flux available. Yes, neutron activation of the reactor walls/components is a problem that we need to solve. However, transmutation of lithium to tritium is required for the reactor to work in the long term, so having a high neutron flux source is a plus in this regard. (and a negative in all aspects of structural integrity...)

The volume amount of activated material that would come out from tokamaks is a fraction compared to the literal tens of tons half-burnt uranium that takes way too long to decay to safe level. The more angrier the radioactivity, the less time it takes to decay away.

I have heard that Windows tends to 'nuke' the EFI boot partition if it's shared with Linux. I'm not sure if it's valid to have two EFI partitions on the same disk, but if the box can handle a second EFI boot partition, that would be a safer option.

There is also the issue that normal windows shutdown does not mean shutdown, but "hibernate". In this state, touching any of the partitions the windows was previously using could corrupt them if mounted in Linux. (The same applies in reverse, and would be even more dangerous.) This doesn't prevent dual-booting, but some care should be taken that the swiched-from-OS was actually shutdown.

Be in one fraction at once. H2O consist of differerent quantum-mechanical portions: para-water and ortho-water.

And it only gets weirder.

paljastusNo. Don't google para-hydrogen. You will break your brain.

Now, provide an example that you cannot, is impossible, to translate into French.

And I'll accept your claim of unknowing is better than knowing.

That implements a ******* VM in which all of the byte code runs in, and rest of source is just byte code listings that the linker magically gathers into a working program.

Just do sysrq+s, sysrq+c (triggers panic) and flip the power switch for instant power off.

Every technology invented is a dual edge sword. Other edge propulses deluge of misinformation, llm hallucinations, brain washing of the masses, and exploit exploit for profit. The better side advances progress in science, well being, availbility of useful knowledge. Like the nuclerbomb, LLM "ai" is currenty in its infancy and is used as a weapon, there is a literal race to who makes the "biggest best" fkn "AI" to dominate the world. Eventually, the over optimistic buble bursts and reality of the flaws and risks will kick in. (Hopefully...)

BioShock infinite was ok experince on linux, I have completed it twice. (The native binary runs via its own internal translation scheme, so I suggest running via dxvk/proton instead for more speed.) I would say however that it'll be a lot more hollow and straight forward "pipe run" than its predecessors. I own bioshock 2, but it's dead, obsolete M$hit only version that i haven't played since it eated my save files three times.

1st problem is that the mercury will highly likely poison the fusion plasma. The blanket is already a hard engineering problem to have it work in a "regular fusion reactor". 2nd problem nobody has said anything about is that you get a mixture of radioactive isotopes out of (a supposedly working) a transmutation reactor. This adds to required enrichment processes: to get 100% mercury-198 (from 10%) and possibly a purification of the freshly radioactive gold.

I'd imagine radioactive gold is pretty much worthless. The Au-197 is metastable, and to my flaky understanding will emit gamma-rays, not to mention the other isotopes generated around Au-197.

 

Me 2023: It will take only a few weeks, right? RIGHT?

A year later: I re-wrote the entire damm plugin. Have a good day.
