This tiny house uses mushrooms as insulation
Lovely example of biomimicry from Ecovative via Grist:
Usually you do not want fungi in the walls of your home. But Ecovative is building a home in which having fungi in the walls is the entire point. The “Mushroom Tiny House” will use mycelium (the mass of threadlike “roots” that mushrooms use to take in nutrition) for insulation.
According to Inhabitat, this stuff is basically asbestos except that it’s not bad for the planet, won’t give you cancer, and is related to something you might put on a pizza…
