DIY experimental Redox Flow Battery kit

cross-posted from: https://lemmy.world/post/33224011

The guys at Flow Battery Research Collective have been designing a Redox Flow Battery development kit that you can build yourself using a 3d printer and a few tools. It's a desktop size flow battery that you can use to either do your own research, e.g. on different electrolytes or just to replicate their experimental findings.

Redox Flow Batteries have the potential to become grid scale or home electric energy storage solutions that are way better for the environment than current lithium based batteries. They can often scale power and capacity independently and allow for repairs.

The FBRC project wants to spread the knowledge on RFBs and help kickstart a global community that develops sustainable energy storage technology in an ope source fashion.

Beware that the project is still in its infancy and sourcing the materials can be a bit of a challenge. Be sure to ask around in the forums for help!

How To Make Clay At Home (It's Just Dirt)

Video notes

Clay is just dirt. Clay can be found in the cracked soil texture or on tire tread tracks.

If the harvested clay is gritty (full of rocks and other impurities) it can be filtered through a regular strainer screen after adding water. After settling for an hour, decant and move into cloth and let dry.

Good clay can be dry processed by just gently pound into powder.

Levigation is continuous decanting after adding water until left with good clay. The resulting good clay can then be left to dry in a trough, for example.

All clay shrinks when it dries, so it needs temper added, which is non plastic material practically: crushed up pottery (clay after firing), volcanic ash or just sand, most common. A good mix is around 20% temper.
