Need to chat with @eco-alex about this one but yes, have been thinking a lot about the earth ship design and how to now incorporate a few new ideas. Electroculture & free energy being the main ones!
Electroculture also talks about copper pyramids & spirals, which on a bigger scale could be built into the design of a house, aiding all organisms living within, humans & plants alike.
I also saw that people can also make their own coal in the soil, I need to refresh how they did that. Similar to the Peat that used to be widely used across the UK and Ireland.
One has to wonder with electricity if there was some sort of reset for this simple knowledge to be lost.
