#2313 Man-Carriable Atmospheric Water Generator #2313 I want to develop a light pipe of alluminum or PVC to collect fresh water from the air. I think a fan would be useful to pull air through the system, but their should be pressure changes to help eek out the moisture into a collector. To develop a light pipe made of aluminum or PVC to collect fresh water from the air, here are some design considerations and steps you could take: 1. Material Selection : Aluminum : It has high thermal conductivity, which can help in condensation if the temperature of the pipe is lower than the surrounding air. It is also lightweight and durable. PVC : While not as thermally conductive as aluminum, PVC is cost-effective, easy to work with, and resistant to corrosion. If used, it may require additional mechanisms (e.g., cooling elements) to enhance condensation. 2. Fan for Airflow : Airflow Design : A fan could be integrated to pull air through the light pipe, ensuring a constant flow ...
