Greensulate

This stuff looks great! Designed to be a environmentally friendly replacement to expanded polystyrene.


"Agricultural byproducts such as seed husks, which would normally be agricultural waste, are used as the building blocks. * Once the seed husks are wet, they are combined with mushroom roots, which act as a binding agent. With a conventional product like polystyrene, petroleum is used as the binder. * The seed husks serve as "food" for the mushroom and the self-assembly begins. According to Bayer, "The factory is the organism" in this highly efficient process. * Mushrooms like darkness, so no light or energy is needed until the end of the process when the material is dried out and shaped. * The "acorn" composite material can be shaped into packaging material for everything from televisions to medicine, and test installations of "greensulate," the organic insulation have already begun."

I would definitely consider using this as insulation for my house one day, an amazingly inventive idea!
