Science Buddies: "Ask an Expert"

Hi,

Need to know if this design will be effective in getting water from air in a energy efficient manner or with very low energy input

Hi,
This sounds like a great project!

Based on the diagram, the basic principles behind it seem to align with the creation of a dew trap, which collects water from the air using the condensation of water droplets in the container (the dew collector). To achieve the most energy efficient design, you would need to create a passive dew trap, and that’s achieved by not using any other energy sources and relying simply on temperature drops, mainly, to create the condensation.

In order to evaluate the energy efficiency of the design, I would need to know a bit more about the heater. Could you please tell me what the heater does in the overall design?
