Off-Grid Tech

@newstart_2024 Nutritionists fed highly-processed sugar-laden breakfast cereal to a group of rats. They fed the cardboard box the cereal came in to another group of rats. Can you guess which group of rats was healthier, happier & lived longer?

Interpretation of a signal determines whether or not it's pain. When a human is in a life-threatening crisis, pain, digestion, the immune system and other distracting, resource-sapping systems temporary shut down so maximum resources can be directed toward a fight or flight response.

@OffGridTech_net @MilkRoadAI Pain is just electrical signals isn't it?

This is WILD! MIT just solved one of the hardest unsolved problems in robotics (Save this). For decades, the fundamental problem with soft robots and wearable exoskeletons has not been compute or AI, it has been actuation. The moment you try to give a soft robot meaningful strength, you run into the same wall every engineer has hit since the field began, fluid-driven systems require external pumps, hydraulic reservoirs, and heavy infrastructure that makes the entire thing impractical to wear or embed into fabric. MIT's new Electrofluidic Fiber Muscles solve that problem by eliminating external infrastructure entirely. The key insight is electrohydrodynamic pumping using electric fields to generate pressure directly from electricity, with no moving parts, no motors, and no external fluid reservoir. The fibers are less than 2 millimeters thick, can be woven into fabric like ordinary textile, and operate in complete silence because nothing physically moves inside them, it is just ions propelling fluid through a closed circuit. The performance numbers published in Science Robotics are not conceptual, they are empirical results from actual hardware. These fibers achieve a power density of 50 watts per kilogram, matching skeletal muscle, with a contraction strain of 20% and a response time of 0.3 seconds. A single bundled configuration lifted 4 kilograms, 200 times its own weight while a separate configuration drove a robotic arm through a 40-degree bend compliant enough to safely complete a human handshake. Another configuration launched objects in under 100 milliseconds, which is faster than a human flinch reflex. The design mirrors biological muscle architecture in a way that prior artificial muscle approaches never achieved. The fibers are organized into antagonistic pairs, one contracts while the other extends, exactly like biceps and triceps and because the system runs in a closed loop, the relaxing fiber serves as the fluid reservoir for the contracting one, which is what allows the whole system to operate untethered with no external tank. The applications are not hypothetical but rather are the exact use cases the industry has been waiting years for the hardware to catch up to. Exoskeletons for physical labor, prosthetic limbs that move with the natural compliance of biological tissue, assistive garments for patients with motor disorders, and soft robots capable of safe physical contact with humans are all immediately unlocked by a muscle technology that is silent, lightweight, and weavable into clothing. The deeper significance is what this technology does when it meets the AI robotics wave that is already underway. Every major humanoid robot program, Figure, 1X, Boston Dynamics, Tesla Optimus is currently bottlenecked by the same hardware limitations these fibers address, actuators that are too rigid, too loud, too heavy, or too dependent on infrastructure to operate naturally alongside humans. Electrofluidic fiber muscles do not just solve a materials science problem but rather they remove one of the last physical barriers between robots that live in labs and robots that live in the world.

@cltheone1 @FightWithMemes Extra-sticky paintballs enhanced with skunk aroma would be more appropriate.

@FightWithMemes To bad this video wasn't filmed thru a rifle scope. Then it would have been easy to solve this situation.

What an absolute psychopath.🤨

@FailCodeGames @MilkRoadAI Injured humans feel pain. Robots don't feel pain.

@MilkRoadAI Whoa isn't that how Muscles work? You send electrical signals and they flex to the desired point, are we just super complicated biological robots?

Emergency Medical Kit (EMK) – Contains core items like: Blood pressure cuff, stethoscope. Oropharyngeal airways, CPR masks, manual resuscitator (bag-valve mask). IV administration set, catheters, saline, syringes, needles, tourniquet. Medications: Epinephrine (1:1000 and 1:10,000), atropine, nitroglycerin, aspirin, bronchodilator inhaler, antihistamine, dextrose, lidocaine, etc. Basic supplies (bandages, gloves, tape, scissors). Many airlines voluntarily add extras (e.g., pulse oximeter, glucometer, or additional drugs), but the core FAA list hasn’t had a major mandatory update since ~2004–2006 (though Congress directed a review in 2024 for things like better anaphylaxis/opioid treatments). Supplemental oxygen is not always guaranteed. Note: In the 2003 case, the cardiologists used exactly this kind of kit for IVs and monitoring—today the same kit is still the baseline, but ground doctors now guide its use in real time. (Telemedicine)

@Rainmaker1973 @OffGridTech_net Where did they get the IV drips from?

A 67-year-old British woman suffered a heart attack during a flight from Manchester to Florida, but was saved thanks to an extraordinary stroke of luck — 15 cardiologists happened to be onboard. Dorothy Fletcher from Liverpool collapsed while traveling with her daughter to attend a family wedding. When the cabin crew asked if there was a doctor on board, 15 cardiologists immediately stood up. The group of specialists was heading to a medical conference in the United States. The doctors quickly sprang into action, using the plane’s medical kit and their expertise to stabilize Dorothy. They inserted IV drips and monitored her condition until the aircraft could land safely. Dorothy later expressed her amazement at the incredible timing, saying she couldn’t believe she was surrounded by so many heart specialists at the precise moment she needed them most. What could have been a tragic situation turned into a powerful story of fate and medical heroism.

Where's the lie? "...caps profits by lowering prices if earnings exceeds 5%" Supermarket net profit margins are generally low industry-wide (often 1-3%); Migros' recent figures show around 3.5%. Do you not understand that 3.5% is less than 5%? Who paid for your education? They deserve a refund.

@Rainmaker1973 @OffGridTech_net Bullshit socialist propaganda. Migros has the same profit margin as every other supermarket.

Fun fact. The Switzerlands largest supermarket, Migros, doesn’t sell alcohol or tobacco in stores, pays no dividends, caps profits by lowering prices if earnings exceeds 5%, is a cooperative with 2M+ members, and donates 1% of revenue to social projects, purely out of the founders moral philosophy.

This California Highway Patrolman shuts down traffic on the freeway for an overturned car accident. Then, he gets in his patrol car and drives to the side of the overturned car and starts pushing it off the highway! 🤯 I will say, he saved lots of time and lots of backed up traffic doing that. Where’s the tow truck? Have you ever seen a police vehicle push an overturned car off the highway like this?

This is the difference between Tesla FSD and human drivers. The Cybertruck stopped for pedestrians, while the humans didn’t. The world will be a much safer place with autonomy.

@skibidiblazor Yes. That's one reason why load is best located near source. An even more important reason is resilience for critical loads.

@OffGridTech_net Have you heard of "transmission losses"?

Thousands of people on this stupid website alternate between asking why we can't build things anymore and throwing toddler tantrums about AI and nuclear power and basically any form of new infrastructure. You are why. Fuck all of you.

@skibidiblazor The amount of parking lot solar canopy potential alone exceeds the entire grid consumption of the U.S. Sodium batteries and linear generators scale much faster than expensive fission scams and gas turbines.

@OffGridTech_net And if you think that scales to gigawatts per datacenter I've got a bridge in San Francisco to sell you.

@skibidiblazor No rational individual is complaining about sodium-based batteries. No rational individual is complaining about rooftop, parking canopy and vertical solar. No rational individual is complaining about multi-fuel linear generators. mainspringenergy.com/solutions/data…

@OffGridTech_net Such as? There's a five year backlog for natgas turbines and solar+battery is only going to make people scream louder about land usage. Coal releases MORE radioactivity than fission in normal operation aside from the obvious smoke.

For 20 years, a $6 knob that takes one hour to 3D print has been grounding Black Hawk helicopters four times a month, and the contractor responsible won't sell us the part or the IP rights to fix it ourselves. So instead, American taxpayers have been paying $40,000 every single time to replace the entire system, multiplied by four times a month, for two decades. That is NOT a procurement problem, that is a shakedown, and it is exactly why right to repair has to be in this year's NDAA.

In one of the most extraordinary crime-solving moments on record, Finnish police cracked a car theft case in 2008 thanks to a dead mosquito. After recovering a stolen car in Seinäjoki with no fingerprints or witnesses, officers were stumped. That changed when Inspector Sakari Palomaeki spotted a mosquito with a swollen, blood-filled belly on the driver’s seat. Suspecting the insect had bitten the thief, police sent the mosquito to the National Bureau of Investigation in Helsinki for forensic analysis. The blood inside it yielded usable DNA, which matched a known suspect. Confronted with the evidence, the suspect confessed to stealing the car, proving that even the smallest clues can solve big cases.

Footage released by authorities in Wisconsin shows a suspect's car go flying over another vehicle as they attempted to flee. The suspect, who is being held on multiple charges, was eventually arrested after a short foot chase, officials said. abcnews.link/RmGHld5

@M_I_C_LLC @ClownWorld Cameras are smart. Drivers and pedestrians can be reckless too. Especially when they're both drunk and/or stoned. Sad example from Ireland: x.com/rtenews/status…

Failure to obey traffic safety laws makes reckless bicycle operators liable, not automobile operators following the rules... Dashboard and Rear View CAM'S ... Just sayin'.... it COULD be the difference between See Your Honor - Zero Reaction Time Due To THEIR recklessness, not mine... and.... You have to believe me Your Honor, that one cut me off and it wasn't my fault...

This is why people don’t like cyclists
