🚨 ROLLS-ROYCE JUST RAN A JET ENGINE ON 100% HYDROGEN AND IT REACHED FULL TAKE-OFF POWER. In a landmark test, a Rolls-Royce jet engine successfully operated at full thrust using only hydrogen fuel for the first time in history. The engine was tested across a complete simulated flight cycle, including fault scenarios, proving that hydrogen can not only burn inside a modern aero gas turbine but can deliver the power needed for real commercial flight. Why this matters: • Aviation is one of the hardest sectors to decarbonize • Hydrogen produces zero CO₂ when burned — only water • This test validates that hydrogen combustion, fuel systems, and engine controls can work together at full power • It moves hydrogen aviation from theory into practical engineering reality The deeper implication is huge: We are now seeing the first real proof that large commercial aircraft could one day fly on hydrogen instead of kerosene. While many challenges remain (especially hydrogen storage and airport infrastructure), this test removes one of the biggest technical doubts: whether a jet engine can actually deliver full power on hydrogen. The race toward zero-emission flight just took a major step forward. What do you think will hydrogen or battery-electric eventually power most commercial flights? Follow for more frontier energy and sustainable technology.

I pitched this idea to Meta for @BeatSaber , but there are other games it could also work for. The Global Frequency The fuzzy abstract vision of the Metaverse, and cinematic visions like Ready Player One, almost always involve crowds of people having a great time. While I remain “the champion of the power of isolation”, I acknowledge that there is real value there, and VR has so far failed to deliver it. For a lot of reasons, it isn’t going to happen inside Horizon Worlds. I propose a concrete, focused experience built on Beat Saber. Playing with friends is great, but the random online servers are tough to match paid music packs on, and the current players tend to converge on Camillia songs, which is offputting for casual players. My suggestion: In addition to the current online play modes, offer a “global frequency” that plays a schedule of songs that an arbitrary number of people can join at once. Thousands. Tens of thousands. Actually, two frequencies: one with just the free tracks, and one with all the paid music packs. The schedule should be viewable in game and on the web, so you could decide to join when your favorite music pack is playing. The nature of Beat Saber offers a unique capability for multiplayer – you can switch difficulty or modifiers between songs at will, and still be playing with the same crowd. The song is forced, but it doesn’t matter how you play. This is key for the Global Frequency, but I would also suggest it as an option for regular multiplayer. In the 60 second intermission between songs, everyone is in “the club”. If you sit out a song, or fail out (and don’t have no-fail enabled), you also drop into the club. Music is always playing in the club, either the current song, or the hook from the song just completed, so everyone has something to move to. Beat Saber avatars are very lightweight, and it should be possible to render hundreds of them, giving a good palette to render the optimally cool crowd scene, which would be the core design question. It would be a fun tech challenge to represent the entire set of thousands of players, but just intelligently picking a hundred good neighbors would still look amazing. Any explicit friends you have that are also playing should be near you, and some effort should be made to allow you to “recognize regulars” that you have played together with before. You should probably be able to walk around and even fly up in the air like Walkabout Mini Golf so you can appreciate the crowd. There are leaderboards up in the sky, with spotlights and other effects highlighting players in the crowd. Someone “wins” the song on each difficulty level, and is celebrated, but everyone has the opportunity to achieve first-completions, personal bests, and full-combo perfection, which result in visible effects for all to see. Every intermission manifests joy for some of the players, which is contagious. The play field should default to the multi player field, with the giant avatar hologram of the global lead player (for your difficulty level), and the other players that were closest to you in score on the last song surrounding you, automatically giving you a competitive field and ephemeral rivalries, but there should be an option to let people play with the single player environments if they want. I would play the hell out of that, and I suspect potentially millions of others would too.

The Falcon 1 is small potatoes now, but reporting on its development is really what got me hooked on @SpaceX. Loved the tales of a bunch of 20 somethings stuck on Kwajalein Atoll trying to make a rocket fly. The company ended up being one tiny error on the fourth launch from going out of business, but it somehow launched and survived. Am still so amused by @elonmusk reading rocket books post PayPal and now getting to this point. Seems just about impossible. Is a shame there has not been a movie made about these times. Hollywood kinda hates Elon and doesn't want to see it made, but it's the ultimate next chapter to The Right Stuff.

Why the Overpopulation Narrative Endures Despite Physical Reality and Elon Musk’s Analysis Overpopulation is the most nihilistic lie ever told. The environmental movement started with a valid point: we need sustainable energy to avoid depleting finite fossil resources and messing with the atmosphere long-term. That core logic is sound that's why Tesla exists. But it got twisted into anti-human Malthusianism: viewing people as the virus, not the solution. Some now openly say eight billion humans make Earth better off with zero. That's insane. Look at the actual scale. All 8+ billion people on Earth could stand shoulder-to-shoulder on a single floor of New York City. Fly from LA to New York and 99.9% of the time you're not over a single person. Vast empty land everywhere. The cross-sectional area of humanity is tiny. Cities create a local illusion of crowding the planet is massively underpopulated. The real risk isn't too many people. It's collapsing birth rates. Fertility is falling below replacement across the developed world, now even in places like India. This is accelerating. Population collapse is the greatest threat to civilization by far worse than climate, AI, or anything else short of asteroids. We've seen it doom past empires. More humans = more brains solving energy, AI, robotics, and making life multiplanetary. We are the consciousness of the universe waking up, expanding from this single fragile planet against entropy. We need to become a spacefaring civilization, not manage decline. Humanity is not a plague. We are the bootstrap for something far greater. Stop the propaganda. Have kids. Build. Expand.
