Bitrefill is now offering 10% Sats back on Claude.AI subscriptions...

I convinced my first Square merchant to try the Bitcoin button. It was the owner of the coffee shop, and he had heard of Bitcoin and was excited to try it. He had to login into the square dashboard on his laptop in the office in order to enable it. He clicked thru a couple disclaimers on the Square dashboard, walked back out to the terminal and Voila. I could pay in Bitcoin. It even asks for the tip before creating the QR code...this was a relief as this always seems to be missing from some of the other lightning workflows I've seen. It would have never worked if I hadn't walked in when the owner was manning the shop. Cashapp gave me 5% Bitcoin back too... Not sure if this is just a cashapp benefit or if this works with any lightning wallet.

do the swiss run empty trains up mountains to burn electricity at peak production? # Regenerative Braking: Swiss Trains as Grid Batteries Yes, this is a real thing! Switzerland uses empty trains on mountain routes as a form of **gravitational energy storage**. ## How it works - Excess electricity (solar/hydro peaks) is used to send trains *up* mountain routes - On the way **down**, regenerative braking converts the descent back into electricity - The mountain acts as a **giant battery** ## Why Switzerland? - Steep Alpine rail lines with strong regenerative braking - Massive hydro capacity that can overproduce at peak times - Nearly 100% electrified rail network - SBB (Swiss federal railway) runs its own integrated 16.7Hz power network ## Not just Switzerland - Norway does similar things - Gravity-based storage is expanding globally (e.g. Energy Vault, which stacks heavy blocks with cranes) ## The catch Efficiency isn't perfect — friction and heat cause losses — but when electricity would otherwise be **curtailed (wasted)**, it's essentially free storage. A great example of using existing infrastructure cleverly instead of building dedicated battery systems.

joe had never needed pit stops after coffee. he always laughed at his coworkers who needed a morning dump. today, however, the coffee was hitting different. maybe it was the coffee, or maybe it was the slop he had fallen into eating lately. either way, it was an unexpected restroom break: joe was a religious person--he prayed before his meals, and he found himself in the silence of the restroom. he fumbled for his phone, a youtube, anything to break the silence. a still small voice, sounded "i know you've been asking about money problems lately--" Joe stopped fumbling for the phone and listened, embarrassed. "Lord, i did not mean to start praying in here" "yeah, well, you dialed in from the stall. it's fine:" "ok, i'm listening" "take care of your health. I'll take care of the money."

ella langley "choosing texas" 😭 ok, so it's #2 song right now...guess it's a 'bout time to hear it. but it kinda hits... I miss Texas & Texans ok, but reality check. --- Jack Daniels is clearly sponsoring the whole thing. so i can see clearly the alcohol industrial complex. --- but still enjoying the song also, funny that apparently Ella Langley is having a whole career and i've been too preoccupied by war, conspiracies, Claude, bitcoin price, "perpetual preferreds" to even notice a whole career.
