Life Forest

We are in a post apocalyptic world where all the plants have died out. Oxygen is generated with mechanical trees. These trees support life in the village with a small ecosystem generating air and minimal power. A storm has destroyed the trees supporting your remote village. This has led to an emergency in the middle of the night. Repair these trees by salvaging what remains of the broken ones. Assemble the parts into working trees, and reconnect them to the local grid.
