This is some nascent tech coming from MIT Labs. By culturing plant cells, this team is on the path of developing 3D-printed wood. Although the focus right now appears to be creating a substitute for lumber, I wonder if it could also be used to develop fuel, like pellets from prairie grasses. It will be interesting to see if this develops into a viable substitute for forest products. Imagine a 3D printer making logs in the woodshed stacking while printing.
3D-printed wood was one of the most promising innovations of 2022. Here is how scientists grew wood in the lab for the first time.
