Back in the 1970s, in Scotland, I saw British subs with bow planes like this. I've always thought bow planes look cool on a submarine.
Our nuclear-powered ballistic missile submarine never released any radioactive substance into the air or water. The primary system (the reactor itself, the primary coolant piping, and the main coolant pumps) was hermetically sealed, with welds. Primary coolant (pressurized water) flowed through pipes in the steam generator, boiling feed water to supply steam to the main engines and turbine generators.
I find this meme a bit hard to believe.
On the other hand, our submarine had no sewage treatment of any kind. When we were at sea, our shit and piss went into the North Atlantic.
The engine room bilges were pumped into a Waste Oil Collecting Tank (WOCT), and not into the ocean. The main engines and turbine generators were steam turbines. They leaked a small amount of lube oil into the engine room bilge. For obvious reasons, this oil could not be pumped into the ocean. It floated into the top of the WOCT, which was only rarely pumped out, and then only from the bottom.
A couple of decades back my wife and I had a most conspiratorial looking lunch with a Russian friend. We had worked together on a LEO satellite based networking system - much like Starlink. The satellites would be launched on Russian rockets - my friend had inherited a Russian satellite company (with 25,000 employees) when the Soviet Union broke up. We met in Paris at a Vietnamese restaurant. My friend used to build Russian spy satellites. And I had worked near people who built US ones. As part of our conversation we chatted about tracking cars and submarines. I wonder if John Le Carre was sitting at a nearby table, listening?
I had not really thought about the difficulties of reading license plates from way up there - the atmosphere plus the oblique angle to see a vertical license plate - creates a lot of distortion.
But tracking of ballistic missile submarines - he explained how they did massive signal processing of ocean wave patterns to detect large objects moving under the surface.
(I had worked on a prior project where we built systems, much as seen in the movies War Games and Dr. Strangelove. These systems lived in places like Cheyenne Mountain. An operator could, at the push of a button display the locations all US and Russian submarines. One of the buttons would change the maps on the wall displays to change the outlines of the continents from shoreline to edge of the continental shelves - most submarines tended to stay in the deeper water out beyond the edge of those shelves.)
When I was still in the Navy, we heard about submarine detection schemes that tried to detect the effect on the earth's magnetic field. Our submarine was more than 400 feet long.
I've never heard of this wave-pattern stuff before.
Of course sound was the primary way of detecting submarines. Soviet submarines were faster than ours, but noisier. Or so they said. We heard a lot about hydrophones installed deep under the ocean.
How deep we normally were was closely guarded. We couldn't be too deep or our VLF antenna wouldn't work well enough. Also, we couldn't be too deep to launch.
So how deep could we go? Back in the day, that was also carefully guarded. We had snap on covers for many of the gauges and dials in the Control Room to use while in port. One of those was the depth gauge.
The Navy also guarded the design of submarine screws. It affected the sound they made. I qualified Throttleman, so I can tell you that not cavitating was hugely important.
Of course now every single one of the FBM submarines of my day are gone. Recycled. If you look on Wikipedia, you'll see the test depths of those 41 subs. They look right to me. For present-day subs, you'll see "+800 ft."

1291. The final Crusader strongholds have fallen, and with them the illusion that faith alone can hold the Holy Land. Yet the Knights Templar return from the East carrying a different prize: the knowledge of Arabic numerals and the revolutionary accounting methods of Liber Abaci. These are tools that measure, connect, and bind — capable of building a network of credit and trust across kingdoms, independent of papal blessing.
When Lord Amaury is murdered on pilgrimage, his friend, Brother Etienne of Chartres, inherits a fragment of an unassuming ledger. In its margins are strange marks — the sign of a hidden architecture of influence. Each symbol unlocks a node in a network stretching from Acre to the Hebrides, mapping the flow of power in the only language that never lies: numbers.
But numbers have no creed. To the Holy See, they are a threat, a rival scripture without saints or miracles. To the Temple, they are the means to replace the authority of Rome with the quiet dominion of commerce. Between these visions, Etienne must decide: should such knowledge be guarded, destroyed, or set free beyond the reach of any master?
The Ledger of Light is a mystery of ideas as much as action — a meditation on the nature of truth, the seduction of control, and the eternal tension between revelation and secrecy. In the dim lamplight of monasteries, on the crowded quays of Avignon, and in the shadowed halls of power, one question burns: when the light of knowledge falls, can any institution — Church, Order, or State — remain unchanged?
*Not a Spoiler* Bitcoiners should take historical note. The French King was utterly broke while the Templars were based and had ample savings. They were a good mark...

An AI-powered monitoring system developed by a team of Chinese researchers has been put into operation in biomanufacturing companies.
The system can accurately predict and control the fermentation process, promoting the transformation of the biological fermentation industry.
Previously, engineers had to monitor production lines 24 hours a day. Now, AI model will analyze the data, to ensure that the fermentation process is always in the best state.
As a strategic emerging industry, biomanufacturing faces core challenges in achieving precise optimization and efficient scale-up of fermentation processes.
Israel’s latest plan to occupy Gaza City reveals that the assault on Gaza is more than just a war over territory. It is a war to extend, suspend, and dictate the tempo of killing and destruction - to exhaust Gaza into submission.

I absolutely will not get into the habit of posting food pictures but it’s so rare for me to find poutine for sale in this country (UK) that I really could not resist. Also, how was I not going to buy a burger called “Big Mary”?
Canadian fast food giants MB Chicken (known as Mary Browns in Canada) have open 4 branches in the UK one of which is in Preston where we’re currently at for the day.
I had a Buffalo Big Mary with my poutine. My verdict ? 10/10 for quality of food and flavour. Absolutely would eat again and again if they ever open a branch nearer me!

Supercapacitors cannot store as much energy as batteries per unit of weight, but they can be made from very cheap components, so it is possible that in the right circumstances, they might be able to store energy more cheaply.
A lifepo4 battery (the cheapest energy storage you'll find) retails at about 70€ for 1kWh of storage. This is incredibly hard to beat, but, capacitors can be made from charcoal and sand...
One of the major limitations of capacitors historically has been the need for layering, each layer requires a plate to inject and remove the power. What's between two plates is called a cell, and each cell is limited to about 1-3 volts.
Plates are typically made out of activated carbon, this is charcoal that has been chemically altered to increase it's surface area. Charcoal is full of small internal passageways from what were once the grains of the tree, the activation process opens these up more. Activated charcoal can reach surface areas as high as 2000 square meters per gram.
The reason why this area is important is because in an electrolytic capacitor, the electrolyte liquid acts as both an electrode and an insulator.
At it's most fundamental, a capacitor is just two electrodes, one positive, one negative, and an insulating material between them. Electrons build up on the surface of the electrodes and that's what gives you your storage.
The storage capability of a capacitor depends on three things: 1. Size of the 2 electrodes (bigger is better) 2. Distance of the gap (less is better) 3. Permittivity of the insulator. Permittivity is just a material property and it's not that important to the discussion.
Electrolytic capacitors are special because the "distance" between the liquid and the carbon it's soaked in is around 1 nanometer, and the size of the carbon electrode can be thousands of square meters, even though it's physically only the size of a marble.
So you might think it's simple, take two giant pieces of activate carbon, put them in an electrolyte bath and you're done... Well, not so fast.
Even though the electrolyte can easily soak all the way through the carbon, the charge can't - or more specifically, it can but it takes ages to complete, so charging and discharging your capacitor will take months.
If you want fast charge and discharge, you need layers. But now you can't just throw carbon in a bucket, now you need to create a carbon coated roll of foil and roll it up.
Commercial super-caps make about 6 watt-hours per KG of weight so unless you can improve on that, you need around 166KG of materials to store 1kWh, which is what can be stored with a 70€ battery.
If the materials are actually charcoal, sand, salt, and water, then there's actually a chance of making an economically competitive supercap, but if you need thin layers of rolled metal foil then forget it.
My idea comes from a practice that is common with "HHO" electrolysis projects. An electrolysis cell is basically nothing more than an electrolytic capacitor with slightly too much voltage being applied, causing it to break down the electrolyte. However, electrolysis is still limited to just slightly more voltage than an electrolytic capacitor, i.e. 1.2-2 volts. But you can see in the picture that 12 volts is being applied. This is because the cell contains "floating plates" (blue in the diagram). The floating plates are not connected to anything, but the electrolyte brings power to them, converting them into active electrolytic plates. So as a result of the floating plates, the voltage between any two plates in the diagram is only 2 volts.
The second part of my idea comes from the fact that a floating plate does not really need to be electrically contiguous. People have successfully used screens as plates, once the screen becomes electrically charged, the electrons don't just "go through the holes". Furthermore, if the screen were broken into parts and some part was not electrically charged, then it's a conductor, which makes it a better path than passing through the electrolyte.
So if the floating plates do not need to be connected to anything, and they do not even need to be large contiguous objects, then there's no reason why you couldn't use a slurry of metallic particles suspended in the electrolyte and let them self-organize into "virtual" floating plates.
This is the foundation of an idea which I'm calling The Mud Cap.
In a pot that is near 200C, create a mixture of: 1. Deionized water 2. Electrolyte such as Na2SO4 (0.1M) 3. A thickening agent such as xanthan gum (0.1-0.5%) to make a syrup-like consistency 4. A temperature based gelling agent such as agar (1%) to make the mixture gel when the temperature drops.
Mix a small portion of this mixture with activated carbon particles in the 25-100um size range. Keep mixing and adding liquid until the electrical breakdown voltage and capacitance of the mixture reaches it's peak.
Pour into a chilled mold causing solidification before the particles have a chance to settle.
Attach electrodes to the resulting block (using graphene paint to promote conductivity) and you have your capacitor.
---
If the average particle size is 50um, the average gap between particles is 50um, and 95% of the particles are not touching other particles, you can expect that electricity will pass through about 95 plates for every 1cm of thickness. Therefore if you consider 1v to be your cell voltage limit, you should have a 95v capacitor from 1cm of this material.
The way to measure breakdown voltage of the mixture is using a probe with 2 plates held 1cm apart and connected to a volt meter and a 200v DC power supply. You briefly connect the power supply sending 200v to the plates which is almost certainly too much for the capacitor and will begin making hydrogen, then you disconnect the power supply and watch the voltage fall until it stabilizes (you have charged this small part of the capacitor).
The major challenge is what's known as percolation. You want as high a percentage of carbon as possible, but too high and it will just bridge conductive paths through the water and kill the cell. Larger carbon particle sizes, and the addition of thickeners such as the xanthan will increase the percolation threshold. I think a good but realistic goal is 50% carbon by volume, but that's including the internal pore structures of the carbon as as "carbon volume".
Estimating the capacitance without building one is a challenge. Amateur Youtubers have had little trouble reaching energy density that is on par with commercial supercaps. One might imagine that with 50% carbon, this design would achieve 50% of the storage because the "plates" are only half dense. But on the other hand, this design also removes 90% of the metal, so it might come out a wash.
You could even remove more metal, by making a 10cm wide capacitor running at 1,000 volts. You could even eliminate more metal by using a rod down the center of a 20cm diameter tube. If you're okay with 10,000 volts then your tube (tank) is 2 meters in diameter. 10,000 volts is of course challenging to work with, but it is possible. Automotive and oil furnace ignition systems operate in this range, it's high but it's not "spooky tesla coil power" range. Conveniently, a 2 meter wide tank is about the maximum size you want to deal with, even for stationary power storage, so everything arrives at it's limit at the same time.
But what will this store? A 3000F commercial supercap is about 1/2 liter of volume and stores 7 watt-hours. You need 143 of those to store 1kWh of energy, which means about 71 liters. So with our 1000v in a 20cm wide tube, we would be looking at 2.26 meters of height.
So like 8 inch 7.5 foot tall tube storing 1kWh and replacing a 70€ battery. In the 10,000v 2 meter example, 2.26 meters of height would get you 100kWh of storage, the equivalent of 7,000€ worth of batteries.
So while the weight and volume is huge compared to lithium ion, the cost feels like it's right on the precious of being economical for stationary power storage.
