> Aptera has this planned but not sure if they ever reach market maturity.
Yes, Aptera does not have a shipping product, and if they ship the current design it might not have a large market for it. The have been promising delivery for a long time now, so it certainly looks a lot like vapourware.
Well but that would be a problem for keeping the car infinitely running with only solar power. But what about just passively charging it while idle? Cars sit idle most of the time.
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).
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

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.
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.
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.
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.
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.
There also was a project car from the Nordics I think. Can't recall the name though.
Main problem is the large amount of energy a car needs vs what kind of surface area you have and efficiency we get.
An ideal (100% effiwncy) solar cell of 5m² would still need 20 hours to charge a 100kWh battery. And we are way off on area an efficiency in reality.
