A computer that needs fire instead of a power outlet Enthusiast built a real steampunk computer that generates electricity from a flame. No batteries or power supply — the fire heats a miniature Stirling engine, which drives a generator to produce electricity. The principle is simple: heated gas inside...

NEW: 🇮🇷🇮🇱🇺🇸 Iran's Minister of Energy says Iran generates electricity through a decentralized system and operate more than 150 power plants that they built entirely on their own. In contrast, the countries bordering the Persian Gulf and Israel generate electricity through a centralized system, which makes them extremely vulnerable

A major gas field in the UK could supply over 10% of the UK's energy, but that gas isn't destined for the grid. The plan instead is to extract it on site, burn it in a local power plant, and use that electricity to mine bitcoin. The energy will be consumed at the source, because that route is simpler and more profitable. Taxes, regulation and grid constraints all add friction. The gas could power homes. It isn't. Because burning it on site makes more money. That is a damning indictment of UK energy policy.

This is a Commodore 1541 5.25" floppy disk drive. It functions as a computer in its own right, with its own 8-bit CPU, ROM, and operating system (CBM DOS). It is its own computer with its own operating system. The Commodore 64 or 128 or Vic 20 or whatever would talk to it over a serial cable and send commands to the onboard computer. These drives were so robust and overbuilt.

How much force does it take to move the KARNO piston? About 4,000 pounds, that’s roughly the weight of an elephant. Most people see a piston and think fuel is exploding to push it down. That’s NOT how KARNO works. Inside the system, gas is heated, expands, and applies about 4,000 pounds of force to the piston. That force moves the piston, and that motion produces electricity

"General purpose computing has run its course, and that we need a new computing approach." "In the past we wrote the software and we ran it on computers. In the future, the computer is going to generate the tokens for the software." "The computer has become a generator of tokens, not a retrieval of files."

A pickle jar can function as a tiny jet engine. The setup is simple: a glass jar with a small hole in the lid holds a volatile fuel like methanol, which evaporates to create a fuel and air mixture inside. A flame brought to the hole ignites it, and the cycle begins. Here is what happens in each pulse. Combustion sends a sharp pressure spike through the jar, forcing hot gas out the lid hole as thrust. The escaping gas creates a brief partial vacuum inside, which pulls fresh air back in through the same hole. Residual heat ignites the new mixture automatically, and the cycle repeats dozens to hundreds of times per second. The jar and hole act as a resonant cavity, which is why it pulses instead of burning steadily. A single opening cannot handle exhaust and intake at the same time, so the system locks into a natural rhythm. It produces almost no real thrust, but it is a clear window into how actual pulsejet engines work, and the physics on display are the same ones used in real aerospace propulsion. Follow for more!

NEWS: SpaceX just made its AI space computer 67% more powerful, Elon Musk says The satellite is called AI1. It is basically a data center that floats in space and runs on sunlight instead of the power grid. Musk says its peak power is going up to ~250 kW, from 150 kW. Its average power is going up to 160 kW, from 120 kW. Why the boost. A single Nvidia Rubin NVL72 rack, 72 of Nvidia's newest AI chips, needs that much power to run. The bigger number means one AI1 can now handle a full rack. Musk's reasoning is simple. A GPU running all day uses about two-thirds of its peak power, even when it is very efficient. So the satellite has to be built for the peak. AI1 works with chips from any maker, not just Nvidia. SpaceX has filed to launch up to 1 million of these satellites. (Source: Elon Musk on X, July 16)

Elon Musk: We use only a tiny fraction of the energy we receive from the sun. “The Earth is almost entirely solar-powered today. The only reason we're not a frozen ice ball at three kelvins is because of the sun. And the sun is responsible for all precipitation. It's responsible for the vast majority of the ecosystem, apart from chemotrophs, at the bottom of the ocean. There's just a tiny amount of energy that people consume to power civilization. It's actually a very tiny amount of energy relative to the amount of energy that the sun sends in our general direction.” Interview at the Computer History Museum, 2013

ELON: HERE’S HOW WE’LL DOUBLE U.S. ELECTRICITY PRODUCTION “If you look at the total U.S. power generation capability, it's roughly a terawatt, but the average power usage is less than half a terawatt. That's because there are big differences in power usage between day and night. So, the daily and seasonal variations in power consumption mean that the United States, and really every country, is only producing about half as much electrical energy as it could. Because without batteries, there's no effective way to buffer the energy. So, what batteries actually enable is that even if you don't build any incremental power plants, you could double the energy output of the United States just with batteries. This is a super big deal. And, in fact, I think that's really where most of the incremental energy production in the United States is going to come from, is literally batteries. So, a bigger deal than it may seem.” Source: Elon Musk, Tesla Shareholder Meeting, November 6, 2025

Just found an open-source tool that lets you see how well an AI can actually use a computer. it’s called OSWorld 2.0. you give the AI a real task on a computer, then watch to see if it can figure everything out and finish it. it gives you: → real computer tasks, not simple questions → tasks that can take many steps to finish → the same computer setup for every AI → websites made for testing → all the files and tasks for free this is also the environment used to test computer-use systems from OpenAI and Anthropic. so if you’re building AI agents, researching computer use, or just want to see what these models can actually do, you can run the same tests yourself instead of relying only on benchmark scores. the labs publish the scores. this repo is where the actual tests come from. bookmark this.

Elon Musk: Solar is already the source of the vast majority of Earth's energy. “A lot of people would say, well solar, can that really provide the energy that we need? A lot of people don't perhaps appreciate that solar energy is already the source of the vast majority of Earth's energy. Without solar power, we would be a frozen ice ball at about 3 or 4 degrees above absolute zero. So really, all we're talking about for solar electricity is taking the tiny, tiny bit of energy that humanity needs for electricity, which I emphasize is super tiny compared to the amount of solar energy that hits the Earth. You could generate all the electricity that the United States needs with about a 100 mile by 100 mile grid of solar power. So you just take like a corner of Arizona, and that would be all the energy that the United States needs.” From: / Youtube, December 4, 2011

🇮🇷 Former Energy Minister: The length of Iran's power grid is three times greater than the distance from Earth to the Moon, and this is an important defensive advantage Ali Akbar Mehrabian: 💬 When the enemy is unable to act, he resorts to terror and the destruction of infrastructure. 💬 A strike on a single bridge or factory is in fact an admission of defeat on the battlefield. 💬 We have hundreds of power stations and an extremely extensive power grid. 💬 The length of Iran's power grid exceeds one million kilometers, which is more than three times greater than the distance from Earth to the Moon. Such a scale in itself is a serious defensive advantage. 💬 Of course, any destruction is a damage, but this war has been imposed on us, and we have no doubt about the necessity of defense. 💬 At the same time, our opponents have a limited number of vulnerable power stations. 💬 Electricity is the foundation of all infrastructure. If their power system fails, the production, processing, and transmission of any type of energy in the region will stop. The question is, can the global economy withstand such a situation?

🚨BREAKING: Huawei just launched an 18-inch laptop that folds down to 13 inches. It’s called the MateBook Fold. And it has no built-in keyboard. Not a gimmick. A signal. For decades, computers were designed around typing. Huawei just asked what happens when the keyboard is no longer the center of the device. What you get instead: A full 18.3” OLED display that folds like a book. Virtual keyboard built in. Bluetooth keyboard optional. Touch, AI, and voice doing the rest. The specs back it up: → 3.3K dual-layer OLED, 1600 nits → Kirin X90 chip, 32GB RAM → 1TB/2TB SSD, 74.7Wh battery → 1.16kg at 7.3mm thin when unfolded → HarmonyOS 5, Wi-Fi 7, 6 speakers, 8MP camera Huawei still calls it a laptop. But this is clearly something else. Part tablet, part screen, part laptop, and possibly the clearest sign yet that the keyboard era is ending. Once the keyboard stops being the default, the entire definition of what a computer is starts to shift. This is not just a new product. It is a test of what comes after the laptop. The companies that get this transition right will redefine personal computing faster than most people expect. Are we moving toward screens that adapt to us, instead of us adapting to the device?

Elon Musk on Raptor 3 Engine: "Raptor 3 is designed to require no basic heat shield, saving a lot of mass on the bottom and actually improving reliability, so that if there is, for example, a small fuel leak from the Raptor engine, it will simply leak into the existing flaming plasma and not really matter, whereas a fuel leak when the engines are contained in a box is a very scary thing indeed. It will be a massive increase in payload capability, in engine efficiency and in reliability. So this is really a revolutionary engine. Raptor 3 is really, I'd say, kind of alien technology, rocket engine. So in order to make the engine like that, we had to simplify so many parts of the design, incorporate secondary fluid circuits and electronics in the structure of the engine itself, so everything is contained and protected. It is a marvel of engineering."
