  • Wind Power Is Taking Off In China– All The Way to 2000 m AGL

    2000 m above ground level (AGL), winds are stronger and much, much more consistent than they are at surface. Even if the Earth were a perfect sphere, there’d be a sluggish boundry layer at the surface, but since it’s got all these interesting bumps and bits and bobs, it’s not just sluggish but horribly turbulent, too. Getting above that, as much as possible, is why wind turbines are on big towers. Rather than build really big tower, Beijing Lanyi Yunchuan Energy Technology Co. has gone for a more ambitious approach: an aerostat to take power from the steady winds found at high altitude. Ambitiously called the Stratosphere Airborne Wind Energy System (SAWES), the megawatt-scale prototype has recently begun feeding into the grid in Yibin, Sichuan Province.

    The name might be a bit ambitious, since its 2000 m test flight is only one tenth of the way to the stratosphere, but Yibin isn’t a bad choice for testing: as it is well inland, the S2000 prototype won’t have to contend with typhoons or other ocean storms. The prototype is arguably as ambitious as the name: its 12 flying turbines have a peak capacity of three megawatts. True, there are larger turbines in wind farms right now, but at 60 m in length and 40 m in diameter, the S2000 has a lot of room to grow before hitting any kind of limit or even record for aerostats. We’re particularly interested in the double-hull construction– it would seem the ring of the outer gas bag would do a good job funneling and accelerating air into those turbines, but we’d love to see some wind tunnel testing or even CFD renderings of what’s going on in there.
    A rear view shows the 12 turbines inside the double hull. It should guide air into the gap, but we wonder how much turbulence the trusses in there are making.
    During its first test flight in January 2026, the system generated generated 385 kilowatt-hours of electricity over the course of 30 minutes. That means it averaged about 25% capacity for the test, which is a good safe start. Doubtless the engineers have a full suite of test flights planned to demonstrate the endurance and power production capabilities of this prototype. Longer flights at higher capacity may have already happened by the time you read this.

    Flying wind turbines isn’t a new idea by any means; a few years ago we featured this homemade kite generator, and the pros have been in on it too. Using helium instead represents an interesting design choice–on the plus side, its probably easier to control, and obviously allowing large structures, but the downside is the added cost of the gas. It will be interesting to see how it develops.

    We’re willing to bet it catches on faster than harvesting wind energy from trees.

    @pocketvj I've liked Friendica for that purpose so far. Of the various Fedi options I have tried it is closest in functionality. It lets you have granular control of who can see or interact with your posts, lets you organize your contacts, can make long posts if you want of like 200k characters, supports making groups, also has a nice rss feature where you can add rss feeds as if they were a contact so they show up in your timeline and can be easily reshared.Features it has that are better than facebook are: no ads, no algorithm randomly hiding your friends posts, can be self hosted so you control the moderation (no more random post going missing for reasons you cant figure out), can organize your timeline by subject matter in addition to by who's posting (you can create and organize saved filters by keywords and hashtags and other parameters to create multiple kinds of timelines), has an option to pick from different UI styles (there's a green style one that I love, it's so peaceful and relaxing), and ability to bridge to follow and post with people other social networks too, even ones beyond ActivityPub. And my favorite: an optional anti doomscrolling feature, you can choose "pagination" instead of infinite scroll.Differences anddisadvantages: At first your timelines are quiet until you start following more people because there's no Meta force injecting "suggested posts" at you constantly. Timeline may also be more quiet than you're used to because it doesnt have addictive UI tricks to keep people scrolling 24/7 (but if you struggle with addiction this is a benefit. I regained hours of my week back). Because it's built by volunteers the default UI isnt as slick. I recommend going in the display settings and using the "bookface" display option which makes it more close to how facebook looks. It lets you control more stuff than Meta does, and some people get intimidated by having so many settings options. Because it's not an invasive privacy predator, it's slightly harder to just look up people you know, no one is required to use a real name, so I recommend joining with a few other folks you know so you can hang out together as you start off.

    @daniel Element only develops the Rust and JS SDKs. And the libOLM crypto library of course. All other SDKs are community projects.On the server side, there is Conduit which forked into conduwuit which forked into Tuwunel which will eventually reach maturity, if the moon is in the right phase. The phone number mapping service is controlled by the foundation. You could use alternative ones or none.I think Matrix is getting there eventually.

    Hello Fediverse, my name is Eric, I'm a journalist based out of Toronto working for an online publication called PressProgress. Most of my work focuses on the activity of Doug Ford's Ontario government. I've produced a number of award-winning podcasts and I have a background in web development. I guess you can say I'm a bit of a coding and podcasting and reporting guy.I'm very interested in the Fediverse's potential and I'm glad to be here. #introduction #newhere
