  • Absolutely it is and it’s a growing movement, my 3d printer is old and cheap but it’s already stopped me buying a whole class of products (i.e. small plastic fixings and cases) the newer technologies are incredibly cool especially some of the pick-and-place enabled multi toolhead models.

    Since I first started following the reprap project home fabrication has increased in quality massively, there are a lot of sites with endless things you can download that have continually improved over the years. CAD and slicers have improved hugely, they’re going to continue to at an increasing rate not only as more people use them but coding tools are getting better too - my projects have benefitted hugely from ai streamlining the coding process I’m sure CAD software writers are benefitting too.

    We’re not too far from ai gen CAD which will be a game changer, having chat gpt style ai help guide you through putting together open source projects will help users too - being able to say ‘i need to upgrade the motor in my washing macjine’ and ai can help select a range of options ‘this motor and that controller or thia controller and that motor…’ finding local companies that will fabricate the parts for you so they plug into the bits you fabricate at home, or local companies fabrication open source designs.

    Collaborative design projects are the key, I’ve been working with a few people trying to find methods that make it easy for large amounts of people doing small things to make meaningful progress on big projects. I think it’ll become common for most people to be involved in at least some form of collaborative project once people are used to using open source designed items fabricated in the way generics are.














  • This is a fascinating one.

    Some things to consider, a toddler can easily defeat a baby but a 40 and 45 year old are evenly matched. There’s also the question of how much is there to learn, at some point the tech tree is pretty much done - iron is much stronger than brass but maybe light-speed heavy plasma guns are pretty much maxed out and physics simply doesn’t allow more.

    This could result in interesting stalemates, a natural limit to the size of conflicts for example if it’s possible to maintain a defensive sphere that can withstand the maximum level of abuse that a circle of attackers can provide - any weapons platform too far back being unable to increase the force applied. We might get technologically perfect civilizations effectively combined to bubbles of influence around their power sources.

    What is possible is that at a certain level of tech we discover how to tap into the universal internet, aliens give us the rest of the answers to physics and philosophy then show us how to build VR gear so we can explore the cosmos in perfect VR and no one ever needs to build Dyson spheres or hyperwarp megastructures because we can do anything with a dark matter powered computanium smart phone.


  • It doesn’t have to be storage, another option is building over capacity so it’s winter output is sufficient then using the excess in summer months to perform useful work.

    For example a desalination and pumping station at the mouth of the Arizona River, you can scale the pumping from a storage lake by the desalination plant to one or more of the upriver lakes raising their water levels to replace the water used for industry and agricultural.

    Carbon capture and manufacture of e-fuels or similar is another great possibility, it can be scaled with energy production vastly reducing the cost of the process and allowing further transition from oil in areas which might otherwise be difficult.

    E-chems are important because there’s a few things which are vitally important to modern industry but currently produced fairly cheep as an oil by-product, if demand for oil derived fuel declines as we hope and production falls dramatically then the price of those chemicals would skyrocket - being able to transition into using sequestered carbon would save a lot of difficulty, and if it helps create a market for sequestered carbon it could help us start bring atmospheric co2 ppm down slowly.
