Imagine a forest that could power its own network of sensors to monitor ecosystem health. Well, this idea is fast turning from sci-fi into reality as more scientits explore how to harvest the metabolic energy from non-animal organisms such as trees.

The latest research by Andreas Mershin’s team at MIT shows that using electrodes made of the same metal gives a current, the electricity comes from a difference in pH between the tree and the soil, a chemical imbalance that is created by the tree’s metabolic processes!

While we are a long way off from powering a light bulb, this is surely an glimpse of a green energy future.

Mother Trees Connect the Forest

It is often said that reality is stranger than fiction. In this video Professor Suzanne Simard shares her latest research regarding forest ecosystems. She reveals that in a forest, trees communicate with each other to ensure resilience and regeneration of the forest as a whole (almost like James Cameron’s film Avatar).
