  • i feel weird about self promoting but I make a project called the Pigrow which is an open source garden automation project designed to be as cheap and flexible as possible by using a raspberry pi and basic components from ebay or wherever. It’s got tools to help you monitor and control the grow environment including various watering tools. It’s not as polished as farmbot but under constant development and having new features added all the time, if you want to set up a cheap irrigation automation system then it might be a good option and if not then i’d love to hear what features it’d need for you to consider using it so i can try and add them.

  • The water wars prediction is especially interesting because when i was young they always pointed to a few locations where it would happen first, and top of the list was almost always Golan Heights where there were already water related tensions and conflict - however what actually happened is Israel invested in a huge desalination project which now supplies all their tap water, they also supply water to their neighbour Jordan who pays in solar power that’s used to run the system.

    Saudi Arabia likewise has eased tensions within it’s borders through huge desalination investment, annalists predicted that competition for water resources would tear the country apart but again what actually happened is they invested in desalination which currently supplies around half their tap water and it’s helped add perceived legitimacy and gained support for the ruling family. Not people i like seeing gaining support but a far better outcome than the chaos and human suffering which was predicted.


  • yes they do that in some facilities, it’s called sewer discharge and can be quiet effective in a well monitored and designed system, surface water discharge uses a similar method of dribbling brine into the water as part of a system that uses ocean currents and tides to disperse the brine back into the ocean.

    While brine return is a complicated and important step it’s really not some major ecosystem destroying problem in any of the modern installs - it’s just important to model and monitor the system, the same way sewage systems find a location where currents carry stuff away and allow it to disperse brine return systems do, with brine it’s just stuff that belongs in the ocean anyway so it all mixes back in fairly quickly.

    A lot of people seem to like to learn the difficulties involved in a new tech and then just use negative thinking to exaggerate it into a reason the tech will never be useful even after decades of improvement and investment. There are huge projects around the world which have done really positive things for local ecosystems, they’re even refilling the sea of galilee after decades of over extraction and allowing groundwater levels to restore.


  • ‘previous waves of digital tech were used to deskill workers and defang smaller companies’ just isn’t even close to true, it’s far easier to access learning resources, tools, and a final market for your product or skills than it ever has been.

    I hate when people look back and say things like ‘technology took away jobs’ when the reality is it’s what ended the brutal privation and poverty as described in works like Jude the Obscure and Ragged Trousered Philanthropists - imagine how different Jude or Robert Tressell’s lives would have been with access to the educational and community organisation resources we all take for granted. Neither of those people had the slightest chance to reach their potential and that was the reality of working class life in those eras, today we all have free access to almost endless learning resources on any subject - we have for many things the tools freely available or at cost thanks to open source; coding, digital art, writing, publishing, film-making… If Joel Haver had been born Robert Tressell or Jude the Obscure then he’d certainly have never made a movie (anachronism aside) but today he and a million other normal people from average lives are able to create art and express themselves freely.

    If anything tech has given fangs to little companies and independent creators, i’ve watched more Joel Haver movies than Marvel movies - one guy and his friends using hobby grade gear, home computers and a lot of passion is enough to make something that people all over the world can enjoy - tech has been fantastic for creators.

    and when creators are able to use AI tools to make that even easier and to increase the scope of their creations it’ll be the big companies that suffer not the small creative groups full of passion, ideas and strong connection to the world they live in.


  • That’s really cool, would be a really impressive thing to see in operation.

    Love the write up too, like the idea of it working at a different pace - maybe it’s designed in a way that it’s got a section that’s filled up with broken and sorted scrap that feeds in whenever it’s hot enough to run - that way most the work would likely be done on cloudy days, after it’s run for a few days they come in and refill the giant hoppers with scrap and when that’s done they go take all the bars or forms it’s made - probably like one of those huge industrial ones that have the conveyor belt of moulds that get filled then roll along something just long enough that they’re cool enough to dump out when it gets to the end and inverts dropping it into a huge pile as the mold goes round to get refilled.

    and yaeh totally agree about the street cars, something i really love about solar punk is that thing of using whatever works for a locality rather than the current global trend of one-size fits all. It would be great being able to travel and actually see different things again, like nearer the equator you’ll see more sun based stuff and up here at 50N we’ll have some mostly associated with summer activities and a lot more wind power, in arid regions they’ll prefer processes that don’t require or can’t tolerate much water where as here we’ll build under the assumption that for most the year eveything’s damp. it certainly would be a more interesting world. I think localized industry is the key, especially a model when things are designed on a global scale through open source collaboration but selected and assembled locally to fit with the culture, tastes, requirements and available resources of the area.


  • yeah, i also really like the idea of algae grown biomas or electronically captured carbon being used for materials for cars, boars, etc - open source cars could have core components designed to last pretty much forever with components that have a shorter life such as body panels and interiors made from bio-plastics, e-plastics, even more traditional materials like wood and ceramics which are still fantastic materials when used in the right place and could come from coppiced trees and managed woodland.
