Step one: Fill everything. Tub, pots, buckets, bottles. You have maybe 45 minutes of water pressure left. That's the cleanest water you'll see for a while. Step two: Confirm the scope. Your house, your block, or your whole region? Battery radio or car radio tells you what you're dealing with. Starlink Mini gives you full details if you have it. Step three: Send one text to family with your status. Then put the phone in low power mode. Cell towers may not last long. Step four: Fridge and freezer stay shut. Snap a photo of both interiors so you don't have to guess. Eat in order: fridge first, freezer second, pantry last. Step five: Stay out of stores. Whatever's in your pantry is the plan. If this is a big event, everyone else is about to panic. Avoid crowds. Step six: Shrink your living space. One small room, blankets over windows and doorways. Critical in winter, similar approach for extreme heat. Step seven: Combustion stays outside. Generators, grills, camp stoves. Carbon monoxide kills more people in blackouts than anything else. This one is life or death. Step eight: Run dark and quiet. Don't be the brightest, loudest house on the street. That makes you the most interesting house. Generator during the day, blackout curtains at night. Step nine: Get comms up. Cell towers may fail within a day or two. Battery radio for info in, GMRS for local family communication out. Step ten: In a big blackout, nobody is coming to help you. Plan accordingly. A few things worth knowing: Blackouts historically last hours to a few days, but the 2003 Northeast blackout affected 55 million people and the 2021 Texas grid failure killed over 200 people. Big events do happen. And likely will happen with more frequency. A whole house generator is great, but a small portable generator with 3 to 5 gallons of stabilized fuel plus a portable power station covers most scenarios and doesn't announce itself to the whole neighborhood. Water heaters hold 40 to 80 gallons of usable water. Learn how to drain yours from the bottom valve. That's a free reservoir most people forget. Practice this before you need it. A weekend without power at home tells you exactly where your gaps are.

💎Scientists and engineers from the UK Atomic Energy Authority (UK Atomic Energy Authority) and the University of Bristol (University of Bristol) have successfully created the world’s first carbon-14 diamond battery. This new type of battery has the potential to power devices for thousands of years, making it an incredibly long-lasting energy source. The battery leverages the radioactive isotope, carbon-14, known for its use in radiocarbon dating, to produce a diamond battery. Several game-changing applications are possible. Bio-compatible diamond batteries can be used in medical devices like ocular implants, hearing aids, and pacemakers, minimising the need for replacements and distress to patients. Diamond batteries could also be used in extreme environments – both in space and on earth – where it is not practical to replace conventional batteries. The batteries could power active radio frequency (RF) tags where there is a need to identify and track devices either on earth or in space, such as spacecraft or payloads, for decades at a time, thus reducing costs and extending operational lifespan. “Diamond batteries offer a safe, sustainable way to provide continuous microwatt levels of power. They are an emerging technology that use a manufactured diamond to safely encase small amounts of carbon-14,” said Sarah Clark, Director of Tritium Fuel Cycle at UKAEA. The carbon-14 diamond battery works by using the radioactive decay of carbon-14, which has a half-life of 5,700 years, to generate low levels of power. It functions similarly to solar panels, which convert light into electricity, but instead of using light particles (photons), they capture fast-moving electrons from within the diamond structure. Professor Thomas Scott, Professor in Materials at the University of Bristol, said: “Our micropower technology can support a whole range of important applications from space technologies and security devices through to medical implants. We're excited to be able to explore all of these possibilities, working with partners in industry and research, over the next few years.” A team of scientists and engineers from both organisations worked together to build a plasma deposition rig, a specialised apparatus used for growing the diamond at UKAEA’s Culham Campus. This development is the result, in part, of UKAEA’s work on fusion energy. The expertise gained in fusion research is helping to accelerate innovation in related technologies.

NEWS: BYD has launched its next-generation battery energy storage system. It has a unit capacity of 14.5 MWh, the highest globally to date. The energy storage system achieves an ultra-large capacity of 10 MWh within a space equivalent to a 20-foot container, BYD said. For a 1 GWh storage plant, it will cut the number of required units by more than half, reduce land use by one-third, and trim cell count by 76%, according to the manufacturer. It uses BYD’s self-developed 2,710 Ah Blade Battery cell, which the company claims is the largest energy storage cell in the world. "This next-generation cell delivers three times the capacity of conventional storage batteries, boasts a cycle life of over 10,000 cycles, and reduces the total lifecycle cost per kilowatt-hour to below $0.014 – a milestone that could reshape the economics of large-scale storage." BYD says it can cut project-level levelized costs (LCOS) by 21.7%. For a typical 1 GWh installation, total costs related to equipment procurement, transportation, and installation are expected to drop by around 30%. In addition, BYD has launched its new GC Flux grid-forming inverter solution, which covers the 2.5–10 MW capacity range. According to BYD, the inverter boasts a performance level approximately 38% higher than common industry standards and a maximum power density of 1,474 kW/㎡, which is around 130% above typical values in today’s market. The system provides an overload capacity of up to 3x for 10 seconds and reaches a peak efficiency of 99.35%.

Elon Musk: Humanity is becoming a superorganism. “What is the Internet fundamentally? It's not a place you get email or post pictures or something. Really, the Internet is like the nervous system for humanity. Previously, communication was more like osmosis. In order for information to travel, somebody would have to call someone with a phone or write them a letter, and then that letter would be carried by another person, by a series of people to the destination. Now, communication can happen instantly from any place in the world to anyone else, and does not need a human to carry it. At a cellular level, a small primitive multicellular creature will just communicate by osmosis from one cell to the next, or diffusion, essentially. But once you have a more sophisticated organism, you have a nervous system. The speed at which information can travel is much faster and the accessibility of information is fundamentally different. Now, with the Internet, you could be in the middle of the Amazon jungle with a satellite connection, and you have access to all the world's information. Whereas previously, even if you lived in the Library of Congress in the U.S. where the most books are, you still would only have access to a fraction of the world's information. This is basically humanity becoming a superorganism to the degree that's not possible unless you have sort of essentially instant light-speed communication from anywhere to anywhere, as opposed to osmosis diffusion.” Axel Springer Pioneer's Talk, December 1, 2020

I just built a Brand Operating System inside Claude Cowork 🤯 A connected system of files that every skill automatically reads from, so your hook writer, brief generator, and script writer all speak in your exact brand voice. All inside Claude Cowork. Perfect for DTC brands and agencies tired of generic AI output that sounds like every other brand in their category. If you're opening a new Claude chat and re-explaining your brand, re-pasting your voice guidelines, and re-describing your customers every single time, a Brand OS fixes the entire loop: → Build 3 foundation files once per brand → Every skill you create reads from the Brand OS automatically → Hook writer pulls your voice + customer pain points → Brief generator pulls your positioning + angles → Script writer pulls the brief + brand DNA → Every output is calibrated to your brand on the first pass No re-briefing Claude on every chat. No editing for an hour to fix generic AI phrasing. No creative that sounds like it could belong to any brand. What you get in the playbook: → The exact Brand OS file structure I use → Templates for all 3 files you can fill in for any brand → The architecture that makes every Claude skill 10x sharper → The exact setup for agencies running a Brand OS per client For agencies: this is how you build a perfect, reusable knowledge base for every client on your roster. Set up the Brand OS once per client, and every campaign after that is already calibrated. I put together a full playbook with the file templates, the architecture, and the exact setup process so you can build your own Brand OS for your brand or your clients. Want it for free? > Like this post > Comment "OS" And I'll send it over (must be following so I can DM)

John Ternus, Apple's SVP of Hardware Engineering, explains why Apple deliberately made the iPhone harder to repair, and why the math says it was worth it: In a conversation with MKBHD, John frames the design challenge by asking you to imagine two extremes: "Sometimes for me I find it helpful to kind of think about the book ends. Like if you imagine a product that never fails, right? That just doesn't fail. And on the other end, a product that maybe isn't very reliable but is super easy to repair." His position is clear: "Product that never fails is obviously better for the customer. It's better for the environment." When pushed on whether infinite repairability and infinite durability have to be mutually exclusive, John acknowledges they aren't always, but explains why the tension is real, using the iPhone battery as an example. Batteries wear out. If you want to extend the life of the product, they need to be replaced. But in the early days of iPhone, one of the most common failures wasn't the battery, it was water: "Where you drop it in the pool or you, you know, spill your drink on it and the unit fails. And so, we've been making strides over all those years to get better and better and better in terms of minimizing those failures." That work led Apple to an IP68 rating, the point where customers fish their phones out of lakes after two weeks and find them still working. But there was a cost to achieving that level of durability: "To get the product there, you've got to design a lot of seals, adhesives, other things to make it perform that way, which makes it a little harder to do that battery repair." That's the deliberate tradeoff. Apple chose tighter seals and stronger adhesives, knowing it would make battery replacement more difficult, because the reliability gains were worth it. John argues the math backs this decision: "It's objectively better for the customer to have that reliability and it's ultimately better for the planet because the failure rates since we got to that point have just dropped. It's plummeted, right? The number of repairs that need to happen and every time you're doing a repair, you're bringing in new materials to replace whatever broke." His conclusion reframes the entire repairability debate: "You can actually do the math and figure out there's a threshold at which if I can make it this durable, then it's better to have it a little bit harder to repair because it's going to net out."
