What a cool idea a great use of what would normally be waste heat — Douglas
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
