Abstract: A Gust Water Trap Apparatus comprises means (9, 42, 52) for receiving air from ambient wind and means for feeding the received air into a compression chamber (46, 56). Restriction means (21, 41) leads from the compression chamber into a condensation chamber (18). The apparatus leads to an increase in the pressure of air from wind gusts so that the air loses energy and is cooled further in the condensation chamber so as to deposit liquid water in the condensation chamber.
