Daisugi, the Japanese technique of growing trees out of other trees (2020)
Summary: Daisugi is a 600-year-old Japanese technique that grows trees out of existing trees, creating perfectly straight lumber. Developed in response to a 15th-century seedling shortage, daisugi prevents deforestation and produces taruki, a timber used in Japanese teahouse roofs. The lumber is 140% more flexible and 200% denser than standard cedar, making it ideal for rafters and roof timber.
