And for rocket fuel you don't generally want something that will happily donate the entire fuel supply with the slightest provocation.

True, but rockets being filled with stuff that needs cooling to very low temperatures in order to not make the rocket go kaboom in a second are not quite seldom, when you think of the ones that require liquid oxygen or hydrogen.

Really this sounds like it would make another fun article in the "things I won't work with" blog

The author of that blog has already commented on N6.

Any sort of combustion-level heat in the presence of nitrogen and oxygen creates lots of messy NOx byproducts (that are all atmospheric pollutants), so, yeah, unlikely to be a pure N6 -> 3(N2) reaction without at least restricting its decomposition environment to exclude O2.

Given the high detonation speed of N6 I would consider it conceivable that almost all of the N6 decomposes into N2 and expands into a not-so-hot-anymore gas before it has a chance to get into contact with the O2 of the surrounding air. But we certainly need to wait for the results of the planned detonation tests before we can really know.

Submission + - N6 aka Hexanitrogen synthesized for the first time, twice as energy dense as TNT (nature.com)

ffkom writes: The air around you mostly consists of Nitrogen, which exists in happy little monogamous pairs of two atoms per molecule, also known as N2. Researchers from the University of Giessen, Germany, recently managed to synthesize for the first time in history N6 molecules, and those appear to be pretty angry little molecules, as they detonate at more than twice the energy density than good old TNT:

A kiloton of N6 is 1.19×107mol, which can release an energy of 2.20×109kcal (9.21terajoules) based on the enthalpy (H0). Considering that the standard kiloton TNT equivalent is 4.184terajoules, N6 can release 2.2 times the energy of TNT of the same weight. On the basis of the documented TNT equivalent based on weight for HMX (1.15) and RDX (1.15)50, N6 can release 1.9 times the energy of HMX or RDX with the same weight.

In interviews the researchers contemplated the possibility of using N6 as rocket fuel, given its superior energy density and that its reaction product is just N2, so basically air, but no smoke, no CO2 or other potentially harmful substances.

Whether you are presiding an authoritative regime in the east or some billionaire's oligarchy in the west, LLMs are welcome, because using them, you only need to adjust one system prompt according to your wishes, instead of brain-washing thousands of civil servants to follow your rule. And this will only get "better" when robots become competent enough to replace police and armed forces, which today may still have residues of an individual moral compass.

Submission + - Sizewell C Reactor cost has doubled to £38 billion but could triple to &po (energyvoice.com)

AleRunner writes: "The total tally for the UK’s latest bet on nuclear power, Sizewell C, is highly likely to rise above the cost of Hinkley Point C." reports Energy Voice continuing, "Taken together, the impact of project overruns and inflation could push up the estimated £38 billion price tag of the nuclear power project, in 2024 prices, by between almost £10bn and £20bn or more." and later states "This would make Sizewell C one of the most expensive nuclear power stations in history; despite advances in EDF’s European pressurised reactor (EPR) technology, and the wealth of experience gained developing nuclear projects.". despite the increases, the article states that "Sizewell C is expected to be up to a quarter more efficient than previous reactors, and that economy of scale should lower the cost of power for the consumer. The project is expected to deliver 'electricity system savings of £2 billion a year on average once operational', the energy department said"

No, I don't need to give you apologies for my correct analysis of your behavior. If you go and shit in the middle of the street I judge you. If you go and hand over other people's data to the big corporates I judge you. No problem here. I'm not putting everyone else down, just those people that choose to do evil. Especially those people that do it so thoughtlessly that they probably aren't even aware of having done it.

Comment Re:Costs (Score 1) 88

It's not enough. The value of electricity is extremely variable based on both location, time and the extent to which it fits with previous plans for electricity. The price that they pay will vary depending on time but if they are coming in with new, unpredicted, demand then the cost of satisfying it becomes even higher and they should be paying even more per unit than the other people that are more or less following what was predicted.

On the other hand, if the AI people can move their demand to places and times with spare electricity, for example the North of Scotland when it's windy, that would mean they could quite rightly get very cheap electricity and not really cause any problem for anyone.
