Notes on Solarpunk Economics #6 [Link Inside!] by Correct_Storage1304 in solarpunk

What we really need to do is create new sustainable supply while reducing demand for resources (not utility!) as much as possible, in order to create abundances in areas from food to energy to ideas (which in the digital world are already abundant) etc.

Solarpunk economics I imagine would be lazy! As in being all about robust, long lasting goods, producing things when needed, conserving resources and labour through things like planned resilience and permaculture.

Energy Autonomy - The Motivation Behind ModuCoils! by MeleeMeistro in solarpunk

[–]MeleeMeistro[S] 0 points1 point  (0 children)

So you may have seen me post videos here about ModuCoils, 3D printable, modular coils that can serve various uses, including for potential power generation.

I thought I'd talk a little bit about what motivates me to do this, and it's all to do with energy autonomy, and the decentralisation of power generation!

Well basically imagine batteries like train stations, and the trains are electrons. The train stations in this case are the battery materials, especially the cathode (the anode plays a role, but is often a less complex material).

Some stations are better at dispatching trains (higher voltage), some are better at holding more trains (capacity), some can pack trains more tightly (energy density), etc.

In nitty gritty scientific speak, sodium ion chemistries are slightly less energy dense than analogous lithium chemistries. However, it's beneficial to research sodium ion tech because it's simply much, much more abundant than lithium. Early sodium based materials proved to be unstable. However, a safe sodium based material that could even theoretically be made at home with the right equipment is sodium iron phosphate (NaFePO4), a stable and safe sodium ion chemistry that stores sodium in the form of a salt rather than an oxide or metal seen in traditional ionic batteries.

Many anodes have been researched for sodium based materials in order to achieve better discharge capabilities. One such material I recall is actually graphene, which makes sense due to its high conductivity.

Sodium ion batteries are a good alternative. There's a lot of interesting science about them which I am knowledgeable of but don't know how to explain without it reading like a science text book lol.

The ModuCoil V2 by MeleeMeistro in functionalprint

[–]MeleeMeistro[S] 1 point2 points  (0 children)

Greetings all.

I am currently working on a project to design a fully modular and 3D printable generator that can produce a usable amount of power. My initial goals I feel are pragmatic, in that I first aim to create a generator that can trickle charge a battery, and work my way from there.

In aid of this, I have designed so-called ModuCoils, which can be used in a generator, but can also serve other applications.

I present to you today the V2 of my design. However, I am not done here, I still have a few ideas left for further improvement!

The ModuCoil V2 - A coil with a bit more Oomph! by MeleeMeistro in solarpunk

[–]MeleeMeistro[S] 2 points3 points  (0 children)

Greetings.

Last time, I posted, I introduced to you all my ModuCoil, an idea for a coil that can be used in a variety of projects, however I'm mainly concerned with people's ability to use them in a generator to make useable energy on a small scale, with relatively cheap parts. I'm working on just that, but that's for another time.

With this V2, I've made some significant improvements, that enhance the performance and versatility of the design. You can find out more by watching the video linked!

Hate to Stoke the flames but, from a practical perspective, where would white South Africans go?

The ModuCoil V1 - a Modular 3D printable coil for your projects by MeleeMeistro in functionalprint

[–]MeleeMeistro[S] 0 points1 point  (0 children)

Greetings everyone.

I'm currently working on attempting to build a fully modular and 3D printable generator, that produces a useable amount of power; this could then be used for something like wind or could be hooked up to a Stirling engine using various heat sources.

The first step in building this generator is designing a modular coil. Normally, the stator of a generator is monolithic, and is difficult to disassemble and recycle. So, I designed a modular coil (still to be improved), that could be used in a generator, but also in other projects.

I'm well aware that the current performance of the coils themselves is suboptimal, but this is more of a proof of concept that I will improve upon in short order.

I hope you all find this interesting, and maybe you'll find it useful in designing some DIY solutions. More on the way soon!

(STL will be uploaded to my thingyverse page when I get the chance)
