Energy scarcity is at the root of many of the problems humanity now faces. This project demonstrates how a thermionic device can be used to harvest energy with unusual efficiency and high enough power output to be useful for many household applications.

This project is a relatively challenging build, and I look forward to seeing people’s attempts at building it. Perhaps they can find some ways to make it easier that I missed. Files, instructions and component lists are included here and also on Github.
