  • true, i guess i was thinking salt water distillation, so maybe contamination would okay. but I asked ai and since it would only be water vapor and that pressure would be temperature dependent then at room temp the would be 0.03 atm so there’s nothing in the vapor part. (at 100 C it would be 1 atm is okay)

    there is benefit to putting a still in a vacuum because it will absorb thermal energy and lowering boiling point save energy



  • You could lower the bucket to boil the seal container.

    I do have trouble imagining two containers with two different pressures but I get you can have a pressure valve like in a refrigeration system.

    The pressure on the seal container would seem to be the same pressure as the phase changes. The container in the video was crushed by the atmosphere so that implies the pressure is lower than atmosphere post phase change.

    But there seems be an issue once the water has became vapor like would the boiling point move enough so that the water would condensate and would condensation reduce the pressure thus lowering the pressure and boiling point.

    There would be water in both the containers and tube. Seems strange that water in the tube at the vapor/liquid barrier would evaporator then condense in what’s essential a similar environment. Its possible when I think about it just the seal container water can evaporate and go back into the tube

    I can’t really do calculations because I don’t know the process yet, but I think boiling water would be more energy than lifting water 34 feet since water heat capacity is so high.

    Right now I do think the flaw would be it being a slow process or even inefficient





  • I want to encourage fedizens and Internet user to collect their own data and run their own algorithms since it’s worked well for corporations in general but to keep using their services. Seems as though people enjoy algo based on their data.

    It’s neat that fediverse has a general principle of not collecting user data, so if more people used fediverse instances more often then less Data going to corporations. This browser extension is outline of how collecting your own data can affect your experience with fediverse. There’s so much you can do with your data and data from api



  • its a browser extension for brave (or any chrome based browser) it’s in the github readme. recomendation algo was self explanatory. it’s meant to recommend you videos on peertube. i only screen shot the only ui that exists, the only things I can screenshot is variables stored in indexdedDb and local extension.

    also the installations instructions are in the github readme

    I did make a classier for for videos that inputs title, tags, description, and closed caption into an LLM. I got roughly 1000 entries classified that way, issue is that most of them were non-english videos and then new videos come from somewhere on peertube that don’t hace these classifiers.

    Video processing is cool just expensive computationally. Also watchers could classify the videos themselves then use a cosine similarity (or whatever algo) on that. I did suggest to peertube to share the categories people say a video is with other people (like it’s a Mastodon post) eventually it morphed into an idea light weight peertube instance that only does api.











  • be better to store the video vector on an instance so that watchers can retrieve, just logistics. video vector (element) can be calculated anywhere just communicated to an instance, the idea is to be flexible. activityhub protocol has made the decisions easy the video vector has to be a .json element in a video json data.

    it would be better to store the results of a calculation to avoid repeated calculations. im looking into music classifications, and like the entire video can be sent to parse to see if its music or not, the tempo, genra, id assume that would be fairly costly to calculate or instance can send the video vector that states all that information



  • i havent made anything yet i just wanted to articulate that a basic algorythm can be done ethically where either instance/watcher/fediverse in general can make a vector to define a video and that could be shared via activity hub and the user can have a vector for themselves and even their own algorithm to sift through videos.

    im just starting and right now i have to figure out how to format the video vector do i want .json .csv .xml
