Re: %ANMeAPs9y

The dymaxion house was a great idea but a terrible business plan - it depended on mass manufacturing to bring the cost down, but it's obviously gonna be a very niche product, what crazy person wants to live in a circular silver house? (I would, but I am a crazy person, most people are much more conservative) to really succeed most plans need to either work on a small scale, be viable and useful for a small group of dedicated crazies (bootstrapping - "have to start somewhere") and then scale up gradually. OR, make a massive gamble on a huge upfront investment, but of course 9/10 of these fail, so for this plan to work it needs to plausibly offer a return of 100x, at least. If the pitch is "affordable housing for all" I'm not sure if the later strategy is viable, because there is already so much money to be made from the current system of artificially scarce housing.

Maybe there is a middle ground, like, cob house 3d printer? okay that's going too far, maybe just a machine that does the mixing, enabling you to build more quickly? I imagine it would be very satisfying to occupy a house you built using nothing but your own physical labour though!

@Dominic Yes! I now have all electrical components, I will experiment with multiple versions of trailers to test the solar panels and batteries in multiple trips. Then we will see! I will get to the aerodynamics eventually!

Re: %ANMeAPs9y

Bad businessman was a self-admitted fault, IIRC from one of his books. I think the explanation was he realized early on that it could take decades for a new invention to get introduced, tested, certified, and accepted by society before it could be produced and he preferred to continue inventing as much of the technology his vision/goal would require (my interpretation/summary of the goal is: all physical needs met for all humanity while remaining within the energy budget of the planet's incoming solar energy, via creation of technological "artifacts').

Sadly he seemingly missed the mark on how receptive society would be to the ideas he was throwing out. He produced a ton of material and I've only scratched the surface, and I've got to believe there are at least a few ideas buried in his work that are worth revisiting with todays technology. An example, a ~$15k 3d printer can print carbon fiber reinforced plastic that has strength:weight ratios comparable with aluminum.
Maybe put a fresh coat of paint to fit modern tastes a little more than the Jetsons aesthetic. Keep the functionality of the dome but put a new skin on it.

With cob, some builders make a very powerful and beautiful appeal to for using only human labor that intertwines state of mind, minimization of reliance on industrial products, community inclusivity, etc. It's very poetic and I couldn't do it justice with my own words since I'm not a writer, but i'd highly recommend 'hand sculpted house'.
There is also a lot of interest in cob that is more purely practical and economical, and from what I've read heavy machinery like tractors/bobcats are the ideal and can mix enough in a few hours for an entire building if all the materials are available and there's space. On a slightly smaller scale are cement/mortar mixers or tillers which are less effective and less labor saving. My opinion is the mixing is where you'd want to invest money/fossil fuel energy to save labor, building with hands is really fun and could be pretty quick if you had unlimited mixed cob.

Even though cob was my gateway as I said before, the more I learn about different styles of natural building the more I'm convinced there are certain techniques suited to different climates, local resource availability and people's preference.

I think it would be sad for humanity if we burn up the last of our fossil fuels manufacturing drywall and cement and shipping it across the planet to build walls instead of using that energy to build solar panels, wind turbines, etc. and keeping dino juice as emergency backup.
High tech buildings are probably necessary for labs, workshops, and that sort of building.
But for my home I'd just like solid walls, roof, nice climate, and maybe some light. I'd like to do that and keep it maintained with minimally manufactured products, and maximally local products.
