How it works
Electrostatic fog collection uses electricity to draw tiny water droplets onto a collecting surface.
In the laboratory approach reported by Damak & Varanasi (2018), an ion emitter gives the fog droplets an electric charge. An electric field draws them onto a metal mesh, where they merge into larger drops and drain into a container.
Water collection and clearer air are separate outcomes. FogLab will test the optical effect by comparing the same collector with its power on and off.
Questions worth measuring
- What is gained over the identical passive collector?
- How does collection vary with droplet size and flow?
- What is the complete electrical and pressure-drop cost?
The records below are a starting point for those questions. Read the original methods and results before applying a finding outside the tested setting.
