1
00:00.000 --> 00:08.000
A fog collector intercepts existing liquid droplets. Harvesting water vapor requires a different phase-change process.

2
00:08.000 --> 00:16.000
Some intercepted water drains; some remains on surfaces or returns to the airflow. Measure each destination.

3
00:16.000 --> 00:24.000
Receiver storage changes with deposition and rainfall minus evaporation, withdrawals and other losses.

4
00:24.000 --> 00:32.000
Report delivered water, energy, maintenance and water quality together. Collected water is not automatically suitable for its intended use.
