"Dual use"

What concerns me is that many years ago, I got in deep merde for the following.

Attempted to source a broken Gen 2 night vision tube for my radiation detector project.

Got as far as finding one, decided it was too expensive (£68) and the following afternoon

had a strange phone call from someone at <agency>

Went like this.

"Hi Mr (full name) living at (address) we have been notified that at (time) you searched for

these modules on a device with IP address xxxx... on a laptop, just to make you aware that

this is a serious matter and we have investigated. As of yet no charge has been filed

but please be aware that if this happen again we won't be as understanding."

Not good!

Iran launches 'biological capsule' to low Earth orbit

Conundrum1885

500kg?

That's not big enough for a WMD.

IIRC, the smallest feasible gun-type physics package is about a ton and that is assuming 90% enrichment on the uranium.

Switching to a composite design with a 239Pu "bullet" wouldn't help, that just makes things more complicated.

Looked into this after watching "Oppenheimer" for reasons, even if somehow they could perfect implosion there is

no way to test it without someone noticing.

Implosion is extremely finicky and the margin for error exceedingly small, even in 1945 there were doubts.

Wasting this much fissionable material is ludicrous, they would be better off using it for fuel.

Now if they could nail down the timing (cough laser detonation /cough) but that adds yet more complexity

and laser diodes with this sort of switching speed are themselves dual use.

Disclaimer: I have looked into this but lack a Q-clearance.

Re: The impending win11 downgrade approaches...

Also have one of these. I looked into upgrading its CPU to an i7 but barely worth it as its only a single step in generation.

The chip in there works fine if you don't want to play 1080p or better video.

Conundrum1885

This machine

Is less than 2 years old, and ALREADY obsolete because it has an older TPM and thus not supported.

CPU is recent (9th gen), GPU same so it *should* work.

To be honest, I know of folks who will take their chances and not upgrade 10, still running a 7 machine here.

Checked and to get something that will support 11 is simply beyond my price range.

Microsoft need to seriously look again at continuing to support older TPM and CPU even if a paid upgrade.

The differences between 1.4 and 2.0 or 2.2 are just not that large.

What really sucks is that most of the older machines WILL RUN 11 but some bean counter just arbitrarily

decided not to support them even though the hardware is fully compatible.

Re: I met a catgirl once.

Staff, not servants.

Got me thinking, an alien ecosystem might yield something that has superhuman intelligence but has a fraction of the body mass because alien biology.

Could the infamous "Black-eyed children" be something this?

What about the Grey aliens?

I often wonder if the strange reports of elves, faerie folks or something like them may be ancient alien encounters.

At least theoretically, something could be grown in a lab from cloned cells with a complex computer program running in a superconducting

3-D reactive lattice with sub quantum limit features, potentially less than 10cm on a side but with a truly insane number of connections

approaching that of a dozen human brains that can operate at a speed in the hundreds of GHz range if you measured on such a scale.

Once you've got that sort of technology, any organic body would work.

Grow the body around the "brain" so to speak, as the biological body matures the neural net becomes more complicated.

Conundrum1885

I met a catgirl once.

She was.. Furry nice.

Gets coat.

Actually did read somewhere that at least theoretically with the right amount of genetic tinkering it might be possible to modify a house cat to have a higher intelligence.

Whether it would be possible to make it as smart as say a gorilla is unclear, then the limiting factor would be developmental.

An average cat lives at most a handful of years, not enough time to learn anything useful even with optimal teaching methods.

Perhaps a better option might be to write the genetic code from scratch, once the key to human level intelligence is known designing a body able to house a brain

that can think and reason at human level but only be a third of the mass isn't ridiculous if you look at Homo floresiensis or one of the other archaics.

There are a number of optimizations present in the human brain due to evolution but if starting from scratch might not be needed.

Re: Quantum slipstream

Well at least theoretically, there may well be a dark matter flow through Earth. Its got an apparent seasonal fluctuation and may or may not affect certain types of radioactive decay very slightly. Only for some isotopes with a very specific structure within the nucleus though.

In this case, the heavier isotopes may react more so extrapolating based on the known data https://www.nature.com/articles/s41598-020-64497-0 a hypothetical isotope of Laforgium aka Unhexquadium (atomic mass 164) with optimal neutron number may be significantly affected. Think of it like the quantum version of a particle accelerator driven sub-critical reactor.

Due to Newton's first law if you can get a unidirectional effect then absolutely the device should produce thrust in the opposite direction.

Might not be significant on the ground but certainly measurable if not useful in space.

I actually did contact CERN not so long ago but think they are waiting on a physics paper before getting back to me.

Not yet having enough of the specific isotope to even test it in the laboratory is inconvenient.

Did look into 'cold fusion' of plutonium 239 and lutetium 184 layered in an ultracentrifuge under high energy pulsed electrical discharge via superconducting energy transfer, yielding Element 165, which might decay into metastable 164.

Would only get a very small (as in a few dozen atoms) quantity per run but enough for testing at least.

Another method might be to use an ion multipactor with 239Pu and a beam of 184Lu produced externally as its got a very short half life, again the problem is tuning that reaction to not break up the newly formed element as fast at it is formed.

Perhaps focus a laser beam on each axis and a WB8 like arrangement to boost reaction efficiency by adding energy to the system?

Quantum slipstream

Looked into actually building a power core (technically a miniature nuclear power plant) but using a quantum field based reaction.

In theory I could build it for a tenth of that cost, but need materials not currently found in nature.

All feasible with terrestrial technology otherwise, if someone can get me even a few grams of this I can use existing materials

and generate a torsional field using dark matter flux at altitude.

Think warp nacelles though it would be limited to a fraction of light speed, this would get me to the Moon and back without

the need for conventional rockets though RCS thrusters would be a useful and necessary backup.

The slight snag is generating a >44T sustained field inside the central core to control the reaction and help regulate, though

can further throttle it using external X-ray emitter tubes of my own design and other methods.

Think of it as a radiometric downconverter that uses intense static magnetic fields to align the spins allowing a reaction to

take place without criticality which allows for a far more compact device.

Also need to build two of them in case one goes bad, with cross connectivity so in an emergency situation the craft is

still controllable.

Interestingly it would work best above 55K feet so can test this simply using a high altitude balloon, this is an approach

I believe pioneered by NASA.

Sharing here in the hope that others had the same ideas.

Can confirm

I also had "Arc Eye" from messing with near UV lasers AND UV LEDs. You'd think I'd learn but didn't know that back reflections even with UV blocking goggles were enough.

Did some tests, and typical green gas welding goggles DO NOT BLOCK narrow band UV from an LED, especially not the sort used for light reactive nail varnish or glue.

Exceedingly painful, and symptoms can be delayed by hours or in some cases days depending on wavelength and exposure time.

Incidentally you can get a mild dose from being outside on a sunny day.

Some fluorescent tubes with specific glass (ie BLB) are less harmful but still not something you'd want to stare at for days on end.

Now, had the Shenzenite manufacturers who sent me the diodes with NO WARNINGS WHATSOEVER or even a datasheet actually done the right thing, I'd have

known that these were in fact hazardous to the eyes.

Was told that they were near UV ie 410nm not as it turned out closer to 370 according to my Note 4 and testing LED vs known UV-B diode.

After speaking to an optician who berated me about not using £xp£n$iv£ eyewear they confirmed no permanent damage had been done.

I did actually consider writing to the manufacturer but its a game of Whack-A-Mole with these folks.

Interestingly UV-C (230-320nm, 2-130mW) can be had if you know where to look, these really will ruin your day.

iPhone 15 Pro Max users report seeing ghostly OLED apparitions

RE. Re. But it's made with Titanium!

Judging by how expensive the iPhone 15 is, I am absolutely sure that they contacted Asgard Supreme Commander, Thor, and had alien metals included in the design.

Latest science news, it seems that 33 Polyhymnia may contain elements that up until now have only existed in science fiction with a Z of 164 or higher.

Someone's almost certainly getting the Nobel Prize if the existence of these elements is actually discovered in meteorites, though it would be exceedingly unlikely

they may exist near the surface of the Moon, just under the surface where mass concentrations (mascons) exist.

I have a standing bet with some physicists that at least one ultra-superheavy element may be superconductive at or near room temperature, in combination with more

ordinary elements.

Because if you're going to travel to the stars, having abundant high Tc and high Jc materials is a good starting point to build a drive with.

More down to earth it seems, deuterium is the magic sauce in at least one prototype OLED display as it emits brighter light without degrading as quickly due to that

extra neutron improving the quantum transition that makes OLEDs emit light. Google "spin triplets" ...

I still say that if Atlantis rises from the waves in peacetime, we should call the first such element "Naquadah" or "Laforgium" or something similar.

The UK's bad encryption law can't withstand global contempt

Conundrum1885

A while back

I found an unbreakable encryption algorithm which is a matrix multiplication using pressed DVD slack space.

The key here is a one time pad which is the ISBN of the disc in question, first ensuring that

the recipient HAS a readable copy then encoding it, putting the disc back in its packet and

giving it to a charity shop in a pile of DVDs to make recovery very difficult.

Then sending the resulting file via an SD card in the post, in the unused space with a firmware hack that

detects someone has put it in the wrong machine and if so immediately zerofills the slack space then

deletes itself.

Good luck cracking that!

Added steps: sending the ISBN using a burner phone, and then rather than burning the phone,

sell it to some bratling for like £4.20 having first ensured that the number is wiped, etc to use as THEIR

burner phone :-)

RRAM chips

Back in the day an early version of a similar (IIRC based on SrTiO3) technology made it into greetings cards.

Interesting note, if they went after the applications where capacity is less important than quality ie for recording video, then they might be onto something.

Having a few odd distortions in a video is a minor irritation, and can potentially be worked around in software by pre-mapping the chip and simply doubling up

on the areas where distortions exist then do on-the-fly corrections.

One thing I could do with is a 25x compatible chip that can store 1-4 GB but only be the size of an 8 pin BIOS IC, however none exists.

Yes there are microSD cards but its not the same and 128Mbit is about the upper limit if you want it to be compatible.

SMR

Some folks here looked into these.

Believe that the idea of using a two-fluid MSR is also being floated.

The mechanism with these is using a liquid fluoride salt in a conventional reactor pin, with any gases evolved being vented under controlled

conditions. The outer salt which is the primary coolant is less harmful as it has no nuclear fuel within.

A somewhat more radical variant uses a modified liquid metal reactor with the fuel suspended within the liquid as tiny capsules

so that criticality only takes place within the highly optimized core that also has control and neutron reflective elements included.

Hybrid design that relies on very thin layers of moving metal driven by gravity, so if anything goes wrong they simply cut off or divert

the fuel flow around the core and it shuts off. Fully throttled and far safer due to minimum inventory of potentially dangerous actinides.

It could feasibly be adapted for space use as parts can be sent up by rocket, with far lower risk than sending up a conventional

fully stocked core if the empty re-entry proof Ir fuel capsules are reused between launches (hey there SpaceX)

Kessler

Fun fact: Russia once had a "Space Laser" but it failed on launch.

I often wonder if its even possible to make something that can fire a multi-MW beam in orbit,

one of the biggest problems is disposing of the resulting heat as COIL lasers are horribly

inefficient being essentially a rocket motor with a laser cavity.

Even the best solid state laser diodes are only 65% efficient even with clever tricks like

recycling the waste heat using TPV modules.

As with many of these hypothetical devices, its nearly impossible to create a beam that can

do much more than damage a distant CMOS sensor which is trivial to mitigate with filters.

Unless your satellite happens to be directly below and can hit something important like a

support beam then its likely that more damage could be done just by using a projectile.

Did look into unconventional devices like a "gravity beam" but this is even more complex

and also suffers from much the same issues as a laser.

Copper shortage keeps green energy, tech ventures grounded

Re: Possible solution....

It seems that one possible approach might be to use hydrides, specifically LaH10X where X is the magic ingredient that permits metallic hydrogen to be stable at near ambient pressure.

I often wonder why palladium sulfur hydrides aren't used, in this case the formula would be LaH10PdS or similar, with the Pd nanoparticles in the La bulk acting as the hydrogen host and the sulfur acting as the catalytic agent permitting Cooper pairs to form at room temperature but more sensible pressure.

The trick would be to get the right mixture, a regular lattice made using nanotech might work here.

RTSC

Not a total loss, seems that room temperature superconductors or at least "better than copper" ones may be possible.

Many years ago I read of a material that fitted the description, using polymers but think the problem was mass production.

In theory at least, using a dual core fibre where electrons and holes flow along separate paths may be more efficient and a

way to increase conductivity over pure copper.

The useful part here, Type III ie dual bipolaron where pairs of electrons and holes with reversed electron spins to achieve

ballistic conductivity may be an efficient way to send energy over very large distances.

At smaller scales using Cu/Ag or something similar for very small yet efficient coils may be possible.

This would also help tame the tendency of pure Cu to produce problematic dendrites at the low end of the discharge curve,

and it does seem that plating this over a conductive polymer core would also reduce the mass of Cu in a given battery.

Likewise, replacing Al (a terrible conductor) with something else would again reduce Ohmic heating within the battery

Its not actually that hard to imagine replacing Cu with Cu/Au or Cu/Au/Sn as an alternative conductor if gold itself wasn't such

a sought after metal.

There was an article not so long ago in Electronics World (tm) about certain manufacturers running into issues with a change in material supplier, as RAM chips are particularly sensitive in this way. Now if memory serves the issue was somewhat resolved using advanced screening and better encapsulant.

Its emerged again with GDDR6, as the feature size is so much smaller even a few electrons out of place can be very bad.

To some extent the more expen$ive cards mitigate by doing at least basic inline correction and/or running at a lower clock rate.

In this case the risk to the end user is near zero, the sort of radioactivity that can affect these is below the threshold of most sensors (α, β) and in fact barely detectable. My sensors only ever saw one case of this and it was 60Co contaminated steel on a USB port, independently verified by a third party with better equipment.
