Circular Pod-Shaped House Heated by Compos

If you’ve ever experienced composting in action, you may know that things can get pretty hot when microbes meet organic material. So what if there was a way to capture all that heat and use it to warm up a cozy little space? Tokyo based architects Bakoko have come up with a circular pod-shaped teahouse that does just that by harnessing temperatures in excess of 120°F that are generated by compost. The designers are taking a simple, biological process and turning it into a viable (and free) way to heat small public spaces like the traditional garden teahouses found all throughout Japan.
