Remember when Bill Gates said electric semi trucks would “probably never be a practical solution”? “The problem is that batteries are big and heavy. The more weight you’re trying to move, the more batteries you need to power the vehicle. But the more batteries you use, the more weight...

More Batteries vs. Submarines Now that the German TKMS and the French Naval Group have massively adopted lithium-ion batteries, following the Japanese lead, this is consolidating as a major trend, just as I had predicted. The next stage will be solid-state batteries, and at that point, we'll essentially be discussing only speed and submerged endurance in comparison to nuclear submarines. Since solid-state batteries are lighter, they will allow for a greater number to be installed, freeing up space for more powerful propulsion systems. Naval Group has already sold a version of the Scorpène to Indonesia capable of remaining submerged for up to 80 days. That's with lithium-ion batteries. Imagine what this could exceed, more than double, with solid-state batteries. In practical terms, a more powerful engine combined with solid-state batteries in the proportions that Naval Group is now using in the Scorpène would provide three times the speed, meaning something like 10–15 knots at constant speed while maintaining around 50 days submerged. This would give a range of 40,000–50,000 km, requiring less than one hour on the surface for a fast recharge. For speeds above 25 knots, simply adding more batteries and a better engine would suffice, as the solid-state system has high power output. All this at 15–20% of the cost of a nuclear submarine. And if the choice is to power the batteries with a micro-reactor, it would cost 25–35% of a conventional nuclear one. Then someone will say: “But a nuclear sub can stay submerged for years.” That makes no difference at all, since even with around 60 days of endurance, the crew still needs to surface to resupply provisions. The big advantages remain: battery-powered subs are superior in silence, and speed can be addressed with larger battery packs.

Today I saw a semi-truck completely flipped over. I bet a Tesla Semi won’t have this problem… No vehicle can eliminate every crash, and physics always wins. But this is exactly why I believe electric trucks equipped with technologies like FSD are the future. Every year, around 500,000 crashes in the U.S. involve large trucks. More than 5,000 people lose their lives, and over 160,000 are injured. Rollover crashes are especially dangerous for truck drivers because of the massive weight, high center of gravity, and the forces involved. Tesla designed the Semi with safety as the priority from day one. It has a low center of gravity bc the battery pack sits beneath the cab, helping improve stability. It also includes advanced cameras, automatic emergency braking, lane departure warnings, and other driver-assistance features that can help reduce the chances of serious crashes. Technology won’t prevent every single accident, but if we can use better engineering and smarter software to reduce even a small percentage of these crashes, that will save thousands of lives over time. I can’t wait for the day when seeing a flipped-over semi becomes much rarer than it is today bc of the Tesla Semi.

If you think it is "cute" or "funny" to be constantly pestered about your weight and called "fat" (even as a joke) when you are extremely thin, you are part of the problem. You normalize the idea that you need to develop an ED in order to be "fit".

Did you know that electric vehicles can go back into Thermal Runaway weeks later? The ‘smoke’ you see isn’t actually smoke, it is a highly flammable, toxic and explosive vapour. Some of the key components are: HCN - Hydrogen Cyanide C6H6 - Benzene C7H8 - Toluene C2H4 - Ethylene H2 - Hydogen O2 - Oxygen CO - Carbon Monoxide CO2 - Carbon Dioxide HF - Hydrogen Fluoride NO2 - Nitrogen Dioxide HCI - Hydrogen Chloride CH4 - Methane It is important to note I’m not against Lithium Ion Batteries (or EVs), they can be a good thing and will no doubt change lives and innovation for years to come, however the technology currently is way ahead of the solution in the event of an incident. We need urgent legislation, education, training and operational guidance for dealing with these incidents. For more information on Thermal Runaway, and the dangers of Lithium Ion Batteries please see the link below (and please check your smoke alarms):

Good morning and where do I start? I’m so proud of the man you’re becoming and I’m so thankful to have you in my life. The first player I met and the first player I had dinner with after I became the receivers coach at Baylor. Yes I’m speaking it into existence but it’s also the feeling I have when I tell you God truly has a calling on your life. The person you are lets me know the lord is and will continue to bless you more than you can imagine. I love you like a son, little brother, nephew, etc…. Played receiver for a big time program like Baylor, played in the NFL, from the great state of Texas but more importantly a GREAT person and man of God. So you have all the tools you need to be successful in this coaching profession but more importantly LIFE! I’m so thankful to be a part of your journey. I’m going to do EVERYTHING in my power with the help of God to make sure you succeed. I told you this and I truly believe it. You’re the next great coach/receivers coach. Love you G and this post doesn’t do justice for how I feel about you or the kind of person you are✊🏾🙏🏾❤️💯 Gavin Holmes

🇺🇸 The Tesla Semi might be the most underrated story of the year... After years of delays, Tesla has finally started taking orders for its electric heavy truck, and the numbers explain why this matters. The 500-mile version comes in around $290,000, well below the $400,000+ that Daimler and Volvo charge for their electric trucks, with longer range and faster charging on top. The demand is already there. California trucking firms have applied for state subsidies to buy over 1,200 Tesla Semis, more than every other electric truck application in the state combined since 2019. The timing could not be better either. Diesel prices have climbed roughly 50% since the war with Iran began, which means electricity per mile has become dramatically cheaper than the alternative, and the new Sparks, Nevada assembly line is built to produce up to 50,000 trucks a year. Same playbook as the Model S a decade ago. Established players dismissed Tesla, then spent billions trying to catch up. The pattern is repeating in real time. Source: NYT

Those investing in submarines today may be wasting money. A Virginia-class submarine, powered by an S9G reactor, has a submerged displacement of around 10,000 tons and costs approximately $4–5.8 billion. Its top speed is over 30 knots. Now imagine a much smaller reactor, with power and weight around 15% of the Virginia's, used solely to continuously recharge a solid-state battery bank. Solid-state batteries weigh about half as much as lithium-ion batteries while offering 2-3x more energy capacity. In practice, this means that with the same battery weight, such a sub could achieve roughly 3x the energy gain, In terms of speed, solid-state batteries deliver double or higher discharge rates (potentially 10–20C vs. 5–10C for lithium-ion), ideal for sustained sprints above 30 knots lasting many days and a cruising speed around 25 knots. All this with 15% less overall weight, much quieter operation on batteries alone, and the same endurance as a conventional nuclear sub. And the cost? A micro-reactor would be 15–25% the price of a conventional one, small, modular, low-temperature/low-pressure. This means that when a more modern reactor is needed, you simply swap the module. A micro-reactor paired with solid-state batteries could make a Virginia-class sub $1.2-1.6 billion cheaper, quieter, and leave far more space for weapons, additional batteries, or crew comfort. That's why this system would put all existing submarines at a disadvantage in terms of cost, space, and stealth. Those not adopting micro nuclear reactors can follow what the Germans, Japanese, and French are doing. The Japanese pioneered lithium-ion batteries with diesel chargers, giving their submarines excellent value for money. The Germans chose a fuel cell AIP system to recharge lithium-ion batteries, while the French opted for a similar Japanese-style approach with a battery configuration allowing up to 80 days endurance, making the new Scorpène highly competitive. Starting around 2030, production will shift to solid-state batteries, tripling the capacity of these conventional submarines and enabling silent navigation at around 25 knots for days,making them superior in stealth and speed to many nuclear submarines currently in service. Submarines powered by solid-state batteries, recharged via micro-reactors, fuel cells, or diesel, will be superior: better armed, cheaper, and stealthier than anything we know today.
