“The Water Roulette”

From Bill Straits Book “The Water Roulette” available on Amazon…  January 1st 2015

...”The likely world leader in this technology is an Australian company, World Environmental Solutions Pty Ltd, who pioneered during what in Australia was labelled the Millennium Drought: a 10-year affair in Australia in the early to mid 2000s. The result was a company that realised making water was desired as drinking water in many cases but the normal method was cost-prohibitive, with electricity costs soaring. One thing was a certain obstacle: the “Watts = Litres” formula. This company today is furthering research and development into its systems of water from the air using minimal power/electricity.

Their water booster (WB) can double the RH at sites where normal operation of an AWG would be inefficient and not advised. That is, the WB can alter 20% RH into 43% RH prior to condensing or 40% RH into 83% RH prior to condensing. (Patent applied for.) This is a real issue for the Sub-Sahara, outback Australia and other arid areas.

The company’s mainstream development was by use of an air-cooled system known as a MultiGen. This consisted of a multi-patented air-cooled absorption chiller and an air cooled AWM operated free from the waste heat of a Turbine or reciprocating generator exhaust. The by-product of this process is to provide cool, air-conditioned air to a space, while making water, all operated from waste energy of an existing Generator, to activate the process they use to operate the condensing cycle. This process dramatically drops the use of electricity by some 95%, as the energy source is waste heat captured.”

 

This particular company has a patented system using Hydro gel filters. These hydro gels can absorb moisture as the air passes through the filter impregnated with Hydrogel substance.  These hydro gels are impregnated into the filter material and absorb moisture as air passed through it; a small amount of electrical power is periodically applied to the filter sub-straight to “desorb” the moisture from the hydro gels. This pulsing effect resulted in water from the air with minimal energy usage. This pulsing system can also be used in front of most AC systems air intake and thus produce water for a very low cost and at very low RH normally necessary for AWG operation. While still in the R&D phase, prototypes are in operation as proof of concept. “
