Ok, beyond just being there for my family, one of my thoughts is integrating Biochar production with Bitcoin mining and then converting the char into a component in 3D printed construction media for producing affordable homes. The char in the walls would act as a filter for the air in the home scrubbing out toxins. It’s produced from agricultural and forestry waste in a process that also produces energy. Building with 3D printing is fast, cheap and low labor. It creates a fraction of the waste that traditional buildings do. They last longer and you can produce shapes and features that were not possible with dimensional lumber creating inspirational spaces for growing humans.
