Structure beans could use recycle paper, plant, nut shell or other carbon "heat" treated material and organic resin such as "wood amber" to make strong compressed materials for making "wood beans" for building support sometimes with iron bars. Concrete and carbon combinations to make tiles, roofing and building walls can be insulated against heat, cold, moisture, mold, unwanted insects. It could become energy efficient and if combined with other materials can become a source for flow of electrons and transmission of energy.
