Self-sufficient systems for water, energy and temperature stabilization.
This category showcases practical solutions for independent living without conventional utilities.
The focus is on simple, functional concepts such as cisterns, earth air systems, sand storage, passive cooling and decentralized energy supply.
The goal is to create supply security, reduce costs, and establish sustainable living and working models – independent of power grids, gas, or central infrastructure.
Suitable for emigrants, self-sufficiency enthusiasts, farmers, and anyone looking to implement a self-sufficient system in their own project.
