capture water from fog in an arid environment
1. Wiry tangles capture fog: lichens
"The Namib close to the coast does, however, have one source of moisture that most deserts lack. Almost every day, a fog rolls in from the sea, billowing across the dunes. On slopes where little else can survive, a lichen grows in a great orange c...

2. Trees comb water from clouds: cloud forests
"Cloud forests, which are dense tracts of evergreens rising thousands of meters above sea level, contribute to yield, but in a novel manner: they literally comb water from the clouds. In the Cascade Mountains of Oregon and other coastal slopes or ...
3. Trenches gather water: flying saucer trench beetle
"A third method involves uptake of free water directly from fog-moistened sand. The most elaborate procedure is used by the genus Lepidochora (Seely and Hamilton, 1976) (Fig. 3 c). These flat, circular, short-legged beetles construct a shallow tre...
4. Rosettes capture fog: Tillandsia
"Plants that use fog as an important watersource frequently have a rosette growth habit. The performance of this morphology in relation to fog interception has not been studied. Some first-principles from physics predict that narrow leaves, tog...
5. Fog-catching materials
Oxford biologist Dr. Andrew Parker and Dr. Chris Lawrence of QinetiQ were studying tenebrionid (Stenocara) beetles in the barren Namibian Desert when they discovered the shell of these insects has a bumpy surface texture. Further research show...
6. Leaves gather water: geophytes
"In the semidesert of Namaqualand and adjacent regions of the former Cape Province, South Africa, there occurs an assemblage of geophytes belonging to eight monocot families and some Oxalis species that exhibit special morphological adaptations of...
7. Body temperature regulated in hot environment: African camels
"When African camels (Camelus dromedarius) do not get enough water, their body temperature's amplitude (the difference between its highest and lowest values) increases from 3.6°F (2°C) to as much as 10.8°F (6°C)." (Shuker 2001:91)
8. Vortex Generator
Watreco's water treatement products use the patented Vortex Generator and the technology platform VPT (Vortex Process Technology) to create energy-efficient, low-cost solutions for several water treatment problems. The system essentially works by...
9. PAX Scientific; PAX Water Technologies; PAX Streamline; PAX Mixer; PAX Fan
Jay Harman began his quest to understand vortical fluid dynamics. The result: a new principle for generating flow that has applications ranging from pump to impellers, fans to boats. All arenas offer improved energy efficiency, smaller devices, an...
10. Aquaporin membrane technology
The Aquaporin company is focusing on mimicking the ability of lipid bilayers in biological cells to transport water back and forth across membranes by way of membrane channel proteins called aquaporins. Aquaporins can facilitate this transport wh...
