Jet Fuel is a fascinating story. We don’t measure it in litres, we measure it in weight, because fuel expands/contracts with temperature while weight stays constant. Jet fuel’s specific gravity is ~0.8, so 1 litre ≈ 0.8 kg (lighter than water). It’s also worth noting that jet fuel is essentially a highly refined kerosene, far less volatile than gasoline, which makes it safer to handle in large quantities. On a long-haul, fuel can be close to half the aircraft’s total weight at departure. On the A350-1000, that can be ~129 tonnes. At most major international airports, this much fuel doesn’t turn up in a tanker. It’s stored in a depot and delivered through a network of underground hydrant pipes to each stand. The “tanker” you see is really a pump truck connecting the hydrant to the aircraft and metering the exact uplift. When I moved from the A340-600 to the A350-1000, one of the things that struck me most was just how much simpler and smarter the fuel system became and how much less fuel we required for the same journeys. On the A340-600, we needed a rear trim tank in the tail to keep the aircraft in balance during cruise. It worked beautifully, but it added complexity. The A350 doesn’t need that, instead, it uses tiny fractions of flap in cruise, together with the latest wing aerodynamics, to keep perfectly in trim. London → New York comparison (typical figures): - A340-600: ~80–90 tonnes of trip fuel - A350-1000: ~50–60 tonnes of trip fuel That’s roughly 30–40% less fuel, saving ~25–30 tonnes on a single flight, which also means about 80–95 tonnes less CO₂ (rule of thumb: 1 tonne of jet fuel ≈ 3.16 tonnes CO₂) 📸 by ig/captainchris

This is the exact moment that I decided to go off-grid in 🇵🇹 Portugal 😂 After being connected to another department and put on hold for 30 minutes, Portugal's electricity provider EDP hangs up on me, for no reason, the second time If you've ever dealt with companies in Portugal, you'll know that every single interaction is just hair pullingly bad: every small problem turns into a giant Kafka-esque nightmarish ordeal that'll stretch out for months trying to get it solved. The level of sheer incompetence of Portuguese companies is just beyond your imagination, I've never experienced this anywhere living all over the world, and I've lived here for a few years now and speak Portuguese Why are Portuguese companies so bad? - nepotism -> they use gov connections/bribes to get monopolies on entire markets, so they don't have to compete much - low competition -> low quality products and services - very exploitative of their workers -> they pay low, treat them like shit, so workers don't care about their work - that makes the companies anti-customers -> they treat you like shit too - all of this is -> very very bad for Portuguese society at large and good for a few rich Portuguese families who control things here People regularly ask me "why are you still in Portugal if so much stuff sucks?", well, because I love it here for the climate, the clean air, the nature, the food, and the people are amazing I feel there's no other solution for me than to just go completely off-grid for my sanity: 📡 I already got Starlink to get internet from space 💸 I've closed my Portuguese bank accounts, and use Revolut to pay my tax 🔋 I'm now getting solar panels + batteries (to quit EDP) 💧 Possibly harvest rain water? If it's not too hard, anyone knows? 🔌 Then disconnect and go 100% off-grid Everything in Asia is so easy and fast compared to here, but that might have made me weak over the years... Being in Portugal everything is difficult, so maybe that makes me stronger? Or maybe I'm just coping though (I can see all the ppl in Asia like Dominik Sobe ツ laughing now over their perfectly cooked Nasi Goreng delivered to them with a smile 😁) P.S. the reason I had to call today was as Kafkaesque as you can imagine: when changing the name on the electricity contract to me, EDP signed me up to their healthcare plan (who knew an electricity provider had healthcare?), they also signed me up to pet insurance (I don't have a pet), and a EUR 600 on-call technician per year (I also don't need that), when all I asked was to change my name on the contract

🚨14 MINUTES BEFORE THE PRESIDENT ANNOUNCED PEACE PROGRESS WITH IRAN, SOMEONE DUMPED $580 MILLION IN OIL FUTURES. Oil crashed 10% that day. And that’s just one entry on the list. On the morning of March 23, between 6:49 and 6:50 AM, roughly 6,200 oil futures contracts worth $580 million changed hands in a single minute. The normal volume for that window is about 700. At 7:04 AM, Trump posted on Truth Social that the US was having “productive conversations” with Iran and pausing strikes. Oil crashed more than 10% that day. Whoever sold first was perfectly positioned. Nobody knows who it was. A senator flagged another $1.5 billion in stock futures traded minutes before a separate Iran post. A Nobel economist called the pattern “treason.” The White House called the accusations “baseless and irresponsible.” But that was just one day. Here’s the bigger pattern. CNN used AI to cross-reference Trump’s financial disclosures against his Truth Social posts. His disclosure lists over 21,000 transactions. What they found. At least 44 stock purchases across 21 different companies. Each made within a week BEFORE he posted a flattering message about that company, its CEO, or its products. The clearest example. In early April 2025, his accounts bought between $200,000 and $500,000 in Nvidia. Days later he praised the company’s US expansion and promised “all necessary permits will be expedited and quickly delivered.” Same pattern with Tesla, Palantir, Micron, and American Eagle. Buy first. Promote to millions of followers after. Then there was the tariff episode. On April 9, 2025, he posted “THIS IS A GREAT TIME TO BUY!!!” Four hours later he paused his own tariffs. The market soared 9.5%. The White House says his money sits in fully discretionary accounts run by independent firms. That he gives no input and gets no advance notice of any trade. He denies all wrongdoing. But watchdogs note he never used a blind trust. So he can always see what he owns. And he was over a year late on disclosures the law requires within 45 days. Now here’s the part that ties it all together. Days ago, Trump Media launched “Truth API.” A data feed built for high-frequency trading firms. It delivers his Truth Social posts to Wall Street in milliseconds. Machine-readable. Before you or I would even see them. Their own CEO said the quiet part out loud. “Markets already move on Truth Social posts.” So the company is now selling hedge funds a head start on the words of the most market-moving man alive. Proving any of it in court is nearly impossible. His posts are public the instant he makes them. And the agencies that would investigate report to him. So the trades stay legal. The posts keep moving markets. And now there’s a subscription to get them first.

AUKUS, Mistakes and Opportunities In 2016, Japan offered Australia state-of-the-art, diesel-electric, ultra-quiet submarines with the option of local production at the Henderson shipyard. The Australian government rejected the proposal, claiming its goal was always nuclear-powered submarines. Instead, Australia decided to spend roughly A$4-5 billion extending the life of its ageing Collins-class fleet until the 2040s . enough money to have bought seven-eight Japanese Taigei-class submarines outright. If that’s really what the government wanted, the Americans and British certainly sent them the bill for AUKUS. Australia is footing almost the entire cost: A$368 billion over three decades. - The United States receives US$3 billion from Australia to expand its industrial base, build more Virginia-class submarines, and then sells 3–5 second-hand boats back to Canberra. - The United Kingdom receives around £2.4 billion from Australia for design and infrastructure work, shares some development costs, and ends up using the exact same SSN-AUKUS design for its own future fleet at essentially no extra cost. I’m genuinely intrigued by how they managed to sell the Australians on this deal. I’d love to meet and congratulate the American and British negotiators – true sales geniuses. Nuclear submarines must have been a childhood dream of that Australian government; there’s no other explanation. But the problems don’t end there. Just as the Americans have cancelled over 300 programmes and thrown away more than US$200 billion in the last 20 years, the British have serious and very recent issues with their own naval projects. It feels like a structural disease in the Western defence industry. - The Astute programme is more than a decade late, costs have tripled, only 5 of the planned 7 boats have been delivered, and engineering problems keep cropping up. - The Dreadnought class (replacement for the Vanguard ballistic-missile submarines) has ballooned by billions and is now delayed well beyond 2030 because of failures integrating propulsion systems and Trident missiles. - And the crown jewels – the Queen Elizabeth and Prince of Wales aircraft carriers – are operational but chronically short of compatible F-35s and cost a staggering £10 billion in overruns. - The Type 45 destroyers suffered catastrophic electrical failures that left them inoperable for years, and the Type 26 frigate programme has been repeatedly cut back, reflecting completely misplaced priorities. And a programme that is supposed to deliver eight submarines to Australia sometime around 2050–2060 is extremely unlikely to proceed as planned, not only because of budgets and operational complications, but because underwater drones are evolving fast and China is leading that race. The Americans and British have a long naval history, but they are also visionaries who understand perfectly well that the future lies in decentralisation: swarms of UUVs, lithium or solid battery submarines, or even small nuclear-powered ones using micro-reactors. These platforms cost 10–20 % of today’s conventional SSNs to maintain, are lighter, and leave far more internal volume for weapons – meaning smaller, cheaper, and more heavily armed submarines. And what does Australia get left with? Far more than just a submarine partnership with Japan – an entire security ecosystem. By 2026-2028, Japan plans to have the HVPG hypersonic glide vehicles fully operational with ranges up to 2,000 km. Their upgraded Type 12 missiles will reach 1,000–1,500 km and can be launched from ships, aircraft, and land batteries. This is enough to cover and protect the entire Australian coastline for thousands of kilometers. And finally, a 3,000 km-range hypersonic missile is being integrated into the Taigei-class and its successor. That arsenal is far beyond anything currently fielded by any Western nation and only Russia and China have comparable systems.

Fast food deserves fast production too. This KFC-style commercial was built with Nano Banana 2 + Seedance on Creatify AI Prompt: [16:9 Cinematic Aspect Ratio | 15 Seconds | Ultra-Realistic, High-Production Ad Film] IMPORTANT CHARACTER CONSISTENCY NOTE: Only ONE single consistent character appears throughout the entire video the same uploaded reference woman in every single frame, from 0s to 15s. Do not duplicate her, do not generate a second version of her, and do not let her face, body proportions, or identity shift or morph at any point. Her facial features, face shape, skin tone, and eye color must remain exactly identical in every frame. WARDROBE & CONTINUITY LOCK: She wears a mustard-yellow knotted crop top, high-waisted denim jeans, and a light beige apron tied around her waist, sleeves slightly rolled up, hair tied in a loose bun with a few loose strands. The apron stays tied on for the entire video it must NOT disappear, change position, untie, or reappear differently in any shot. Her hairstyle, clothing, and accessories must remain 100% consistent from the first frame to the last, with no sudden changes in outfit, hair, or styling between cuts. NO GLITCH / NO ANOMALY RULE: The video must have zero visual glitches, no flickering artifacts on her body or face, no extra limbs, no duplicated objects, no morphing hands, no random object teleportation, and no unnatural warping during transitions. All elements must stay spatially consistent and appear/disappear only through natural, intentional actions never abruptly or without cause. VOICE & DELIVERY NOTE: She speaks in a natural British (Received Pronunciation / soft London) accent throughout. Her voice should carry real emotional texture not flat or robotic with natural breath, subtle vocal fry when tired, and a genuine laugh, not a scripted one. Pitch and volume should rise and fall based on her emotional state in each moment: 0–3s line ("I still have so much left to do..."): Low volume, low pitch, tired sigh-like tone, trailing off slightly at the end sounds drained and flat, almost muttered to herself. 3–5s line ("Okay, one bite won't hurt."): Slightly hushed, playful, a small guilty smile in her voice, pitch lifts a touch on "won't hurt" like she's convincing herself. 5–7s (no dialogue): Only a sharp, involuntary inhale/gasp sound as she bites breathy, high-pitched micro reaction, almost startled. 7–11s line ("Wait... did that seriously just happen?"): Voice rises in pitch and pace, breathless with disbelief, volume increasing toward the end of the sentence, genuine excitement creeping in. 11–15s line ("This isn't just chicken. This is cheat-day magic."): Confident, warm, higher energy and volume than any previous line, a light laugh embedded before she speaks, ending on an upbeat, slightly playful high note for "magic" full smile audible in the voice. PRODUCT NOTE (Bucket Appearance): The KFC packaging is a medium-sized cylindrical paper bucket, wider at the top than the base. It is white with two bold vertical red stripes on opposite sides. Centered on the front is the classic black-line illustration of Colonel Sanders' face bald head, glasses, thick mustache, and beard with a black bow tie beneath it, and the word "KFC" printed in bold black uppercase letters below the illustration. The bucket has a slightly textured, matte paper-cup finish with a rolled/folded rim at the top edge. It is filled generously with golden-brown, deep-fried crispy chicken pieces piled slightly above the rim, with visible crispy, ridged breading texture and light steam rising from it. This exact bucket design, color, size, and branding must remain identical and consistent in every single shot throughout the video. 0–3s: A bright, airy kitchen on a sunny morning white marble countertops, open wooden shelves stacked with jars, a large window above the sink letting in soft natural light, and fresh vegetables scattered across a cutting board. The young woman stands at the counter, visibly tired, chopping vegetables slowly for a salad, occasionally pausing to rub her wrist, surrounded by unwashed dishes, a grocery list stuck to the fridge, and a timer ticking on the oven for something else she's cooking. She mutters under her breath (per voice note above), "I still have so much left to do..." 3–5s: A knock at the door she wipes her hands on her apron (apron remains tied throughout), walks over, and returns holding the KFC bucket exactly as described above, light steam rising from the freshly delivered chicken. She sets it on the counter beside her half-made salad, lifts a golden, crispy fried chicken leg piece toward the camera. She grins and says softly (per voice note above), "Okay, one bite won't hurt." 5–7s: Extreme macro slow-motion shot as she bites into the crispy skin the crunch detonates with deep, cinematic intensity. The impact sends a burst of energy through the kitchen: the curtains above the sink billow outward, the vegetable peels and grocery list flutter into the air, the oven light flickers, and golden light particles swirl around her. Her hair sways loose from its bun in the sudden gust as time seems to hold still for a beat. Her outfit and apron remain exactly as before. Only her sharp inhale/gasp sound (per voice note above) no spoken dialogue. 7–11s: The energy settles into a vibrant, glowing atmosphere. The kitchen comes alive on its own vegetables chop themselves into neat piles, the salad bowl assembles itself, the oven timer stops with a satisfying ding as the dish inside finishes perfectly, and dishes stack themselves clean in the rack. She watches, stunned, and says (per voice note above), "Wait... did that seriously just happen?" Bold animated text sweeps across the bottom third of the frame: "Kitchen: Sorted." She remains the same single character in the same outfit throughout. 11–15s: She laughs, looks at the chicken leg piece in disbelief, then confidently raises the same KFC bucket toward the camera. The camera pushes in with bright, glossy cinematic lighting as she smiles wide and says (per voice note above), "This isn't just chicken. This is cheat-day magic." The scene ends on the same KFC bucket glowing in warm sunlight, with the logo appearing top-center and the tagline sliding in from the side: "KFC One Crunch. Zero Effort."
