In 2026, the PSP will be as old as the Commodore 64 was when the PSP launched.
Did not expect a question that starts out 'Do you think before you speak?' to go so well. A+ question from Charlotte Harpur A++ response from Eileen Gu.
Some random dude from Guinea just retired after an OpenClaw bot with access to his owners crypto wallet sent him $250,000 instead of $4
🚨🔋Donut Lab Brings the Receipts: Finland’s VTT Lab Verifies Donut Lab’s 0–80% Solid-State Charge in 4.5 Minutes. 🍩 Last week, I shared how Donut Lab was facing heavy skepticism over their claims of a production-ready solid-state battery. Today, things are starting to get much clearer, which makes believing in this a bit easier. The VTT Technical Research Centre of Finland, a government-owned lab, just released independent test results. For those of us living with EVs, the data is worth a close look. Here is what the lab actually proved regarding charging performance and why it matters: •The 5C Test (Under 10 Minutes): To put this in perspective, a typical EV today takes about 30 to 60 minutes to charge from 10% to 80% at a fast charger. In the first phase of testing, the lab pushed the cell at a 5C rate. Even with very basic cooling, the battery reached 80% state of charge in less than 10 minutes. When they removed the cooling to let it run hotter, it finished the full 0–100% charge even faster, in just over 12 minutes. •The 11C Test (The 4.5-Minute Mark): This is the extreme speed test. An 11C rate is roughly 11 times faster than the battery's standard hourly capacity. The cell hit a 0–80% state of charge in exactly 4.5 minutes. This is about five times faster than the best fast-charging performance we see on the road today. •The Thermal Advantage: In most batteries, heat is the enemy. It forces the car to slow down the charging speed to protect the cells. With the Donut Lab cell, the opposite happened. As the temperature climbed to 89°C during the 11C test, the battery’s internal resistance actually dropped. This allowed it to maintain that extreme charging speed for longer without having to "throttle" or slow down. If this tech scales to a full battery pack, it turns a charging stop back into a refueling stop. It is fast enough that by the time you walk inside to use the restroom, your car is already ready to go. Independent verification from a state lab is a massive hurdle to clear. If this is a scam, they deserve an Oscar for the level of detail. If it is true, they deserve a Nobel Prize. What is your take? Source: …e113bb711e441db5c353d2d31abbb3.r2.dev/VTT_CR_00092_2…
