HARVESTING OF WATER FROM FOG USING SPONGES
Abstract
Supervising Professor: Cheng Luo
A sponge has porous structures. It is capable of both storing and transmitting
water. In this work, we explored the possibility of applying three different types of sponges
to collect fog. We also compared their fog-collection efficiencies with that of a typical
Raschel mesh that is widely used in the field to collect fog. We found that, for three different
fog speeds, the fog-collection efficiencies of three tested sponges were 39% to 93% those
of the typical Raschel mesh, indicating that the sponges could serve as alternative fog
collectors when well-developed collectors were not available. Sponge 3 has the best
performance. Its fog-collection efficiencies were 52% to 93% those of the typical Raschel
mesh.
