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.

Sean has built DUDE Wipes to over $150M. It's one of the strongest brands on planet Earth. In this video, he addresses the age-old question of how to invest in Brand Marketing in a world that's obsessed with measuring the short-term return from performance marketing. As a recovering performance marketer myself, learning this lesson was one of the most humbling but value-unlocking realizations in the journey to the 9-figure exit We learned many of the same lessons Sean gives here, which helped us gain confidence in broadening the set of people we were reaching (via paid, unpaid, and everything else) with content and tactics that aimed to reach tons of ppl AND increase the probability the Brand came to mind when the buyer went in-market vs. focusing all efforts on converting those already in-market to get a good ROAS number Btw, I was one of those marketers who, for too long, lived by the idea that if it didn't show up in the reporting within our short-term attribution window, it didn't exist. But hey, my loss is your gain, so here are the 6 most helpful lessons and quotes from the video 1. It's about balance. "If you're too focused on branding or too focused on performance, you're going to end up hurting yourself because you're going to be stuck in one lane" 2. Only when you invest in Brand can you fight increasing acquisition costs with performance marketing "You have to be spending on performance marketing where you can track the return and understand how to acquire customers. Then you have to be spending on building the Brand where it's not as trackable, and that'll actually make your performance work better." 3. Do it all. Find what works for YOU at YOUR stage "Sampling, getting your product in people's hands. Experiential marketing. You have to do everything well, and then you have to find the mix that works the best for your Brand. And that's going to change over time." 4. Ignoring Brand early on is a deadly trap "So early on you may have to be spending typically more on performance because the dollars really got to work for you. One pitfall is that people ignore brands early on because of that. They get lost in the Meta D2C loophole, and that's like a drug." 5. The Brand has to be able to stand on its own outside of the Meta Loophole "You're only, you're only as good as your last hit as your last click. As soon as you stop paying that money -if it's all DR Advertising based, you don't mean anything to anybody and your Brand can't live on its own" 6. Saying you don't have the money to invest in Brand is a lazy excuse. "That doesn't need to cost a lot of money in the beginning. That's where we learned the guerrilla tricks. You should always be a guerrilla building your Brand. Don't use the excuse of 'oh well, we don't have the funds to build a Brand'. We never had the funds. We built a Brand, so it's not about the resources. Be resourceful. Be creative. Find ways to get your Brand out there" #brand #performance #marketing

💎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%.

Guys, you won’t believe what happened to my brother yesterday. 😭 He got home around 11 p.m., parked his car outside and went to sleep. The next morning, he came out to use the car and noticed the bonnet was open. He opened it and… his battery was gone! 😭💔 He called his mechanic and told him he was scared to buy another battery because the thieves might come back. Later that evening, they went to a battery shop to get a replacement. The first shop was closed, so they entered another one. Guys… guess what my brother saw on the floor? HIS OWN BATTERY! 😭😭 He had written his name on the battery because it was brand new, so there was no mistake. They asked the person who brought it, and he claimed he bought it from someone else. They called that person… And it was the actual thief! The most shocking part? The thief was just a 13–14-year-old boy. 😭 He even demonstrated exactly how he opened the bonnet and removed the battery. That’s the video you’re seeing here. And guess how much he sold a ₦120,000 battery for? ₦15,000! 😭💔 Imagine waking up to discover your battery is gone, then finding your own battery in a shop the next evening. 😂😭 This country sha… you really have to watch everything. Car owners, please secure your cars properly. And parents, we really need to pay attention to what these young boys are getting involved in. Have you ever experienced something like this before?
