I think this "* The software is pretty specific to my requirements." is the biggest part for me. I built something with Antigravity over the holidays that I can use for myself and it solves my use case. I tried thinking about if this can be helpful for others and pushed it a bit further into a version that could be hosted. Which does not make that much sense because it is a computationally intense numerical solver for thermal bridges and just awfully slow on a free hosted platform. But the project was a couple of evenings and would otherwise haven taken me half a year to complete (and thus never been done).

https://github.com/schoenenbach/thermal-bridge https://thermal-bridge.streamlit.app/

I used it with gemini 3 in tandem to build an app to simulate thermal bridges because I want to insulate a house. I explored this in various directions and there are some functionalities not completed or sound, but the main part is good and tested against ISO/DIN test cases for this kind of problem. You can try it here, although the numeric simulations take quite a while in the cloud app

Disclaimer: I'm not a programmer or software engineer. I have a background in physics and understand some scripting in python and basic git. The code is messy at the moment because I explored/am still exploring to port it to another framework/language

Very cool game. Immediately reminded me of pathery, which I can also recommend to everyone who enjoys this.

This is exactly the idea behind the concept of a memory bank that I think Cline introduced first. It serves as a goto for project overview and current scope and goals the project has.

Ah, I'll check this out thanks.

You might want to get into touch with some museums on science topics to see if they are up to show it. I live in Germany at the moment and know of at least two MINT focused museums that let visitors engage a lot with their (sometimes digital) exhibits and this here checks all the boxes to make a great exhibit.

Very well done, I'll try to see if my children will enjoy that already too.

Absolutely!! Talk to MoMath in NYC too

I'm happy to find a contact there if you want

We've had similar struggles and something like a babboe or urban arrow won't fit. I was 95% close to ordering a Libelle https://leichtlast.de/ The non-motorized unsplittable version weighs around 20kg, the splittable slightly more, but it is splittable.

We then settled for a Muli https://muli-cycles.de/en/

I still sometimes think the Libelle would have been cooler but the motor is stronger on the muli and I'm very happy with it too.

I really like the cargo basket on the Muli. I've kind of had my eye on the Omnium (https://omniumcargo.com/de/shop/produkt/cargo-v3-wifi/#frame...), there's a hinge attachment for the rack which can make it a lot narrower. (https://damgood.bike/products/ouch-1-omnium-utter-cargo-hing...)

A very big database comparing a lot of relevant data can be found at https://www.eurovent-certification.com/

I only used it for air-to-air heatpumps (or air conditioners as they are sometimes called). He the data is oretty good. I can't say anything about the other types of heatpumps but I've found the database quite useful.

There's been a recent video by the German "Sendung mit der Maus" (basically how does stuff work for little children) about these kind of generators. I did not double check if the company in the video is the German one mentioned in the article, but chances are high. Video and subs are in German only, but it's less than 10 minutes and one can see a little how it works.

Very cool. I noticed that the radio-controlled unit that steers the kite has its own little wind turbine for power.

Why are these people wearing safety helmets? Does this imply that everyone living under the kites will have to wear one too?

They're under a crane lifting stuff up overhead on a work site, that's probably why.

Falling bolts and tools don’t really care if they’re on a construction site or not

Maybe just the ones living under the crane while it's lifting stuff over them.

That also assumes people are living under the kites.

I think you're overthinking a short demo video and hats. I doubt anyone fought hard against wearing it, and company liability is different from your own personal risk assessment.

I doubt people will be living under the kites. I doubt there can be anything in the vicinity of the kite flying range for that matter, so no windmills or high tension lines or buildings or anything, which limits this thing's options especially in higher density countries like NL.

no, it's because the are directly at the site where the kite is launched (and on national tv)

The most efficient air-to-water heatpumps are using propane. Just look for lambda and ovum from Austria.

Came for this comment. Why is there no COP/SCOP mentioned at all... If you want to get into the market you should be competitive. And the COP of 4.0 you mention is actually the lower end. I'm heating with an AC as air-to-air heatpump now for the second winter and I chose the most efficient that I could get with a SCOP of over 6. And for the first winter I also could reach these numbers.
