New filter membrane lowers electricity use in air conditioners
by Mike Adams, the Health Ranger, NaturalNews Editor
Born of nanotechnology, this micro-membrane has virtually unlimited applications, including lowering AC and heating bills, as well as making military uniforms resistant to chemical warfare.
While the membrane name may not roll off the tongue, this ultrathin sheet has some intriguing possibilities: lowering air conditioning and heating costs, making military uniforms more resistant to chemical and biological warfare, desalinating water, keeping barnacles from growing on the bottom of boats.
The membrane is a product of nanotechnology research, a growing field of high-tech work that uses molecular-sized building blocks.
According to a report last year from the Micro and Nanotechnology Commercialization Education Foundation (www.mancef.org) some experts have predicted up to a $1-trillion market by 2014.
Born about 10 years ago from an idea for developing fuel cells at Rensselaer Polytechnic Institute in Troy, N.Y., the company moved to Florida in 1998, lured by tax breaks and assistance to Pasco County.
"The fact that Florida offers a reasonable cost of doing business is a plus for us," said Tim Tangredi, president and chief executive.
The state also offers a perfect working environment for Dais-Analytic's technology: lots of heat, lots of humidity.
Its first commercial product, called ConsERV, is used with heating, air conditioning and ventilation systems.
As part of the process, chains form that create microscopic channels that allow molecules of water to pass through the filter.
The membrane, which looks a little like wax paper, can be from 6 to 40 microns thick, according to Scott Ehrenberg, the chief technology officer.
For comparison, it takes 25 microns to make up one-thousandth of an inch.
A sheet of membrane is put onto a plastic mold, bonded with heat and then placed in a case that makes up the filter.
It has been certified by the Air-Conditioning & Refrigeration Institute, a national trade association and has been included in incentive programs by Progress Energy and Florida Power & Light.
