REMOVING WATER VAPOR FROM AIR USING ELECTROSTATICS
Date: February 21, 2001
Time: 6:00 PM
Speaker: Stuart Hoenig
Place: AME S202 at the U of A
Even though water molecules do not have charge, they are asymmetrical, and are subject to respond to an electrical field gradient.
A system has been developed using a series of needles carrying a negative voltage (15kV) to remove water from air. The molecules are collected at the needles and then driven to and through a grounded screen. At this point they are collected and removed. In a typical operation air at a relative humidity of 95% is dried to the 30-35% value. The present system operates at a flow velocity of about 150 feet per minute. This system and similar systems can be used to purify water and air as well as destroy bacteria. Come to the meeting and see what its all about!
Dr. Hoenig is a retired professor of Electrical and Computer Engineering from the U of A. He has been working on this system with Jim Cole, a retired ME.
The Tucson Section has standing committees whose chairperson is not elected, but is appointed by the Section Chairman. If you are interested in any of these positions or are interested in having a say in what the Tucson Section does, please notify Joseph Wu at firstname.lastname@example.org or at 519-0904.

Feedback and Volunteering
We need to hear from you! We want to know what we can provide to make IEEE a better organization. If you have any ideas for meetings, any activities that promote engineering and the IEEE, let us know! We’d like to hear from you.
Also, remember that we run this as a set of volunteers. If you put something into this organization, you can get much more out of it! We need you to help out! Contact us!
EMC Fest 2002
Is Electromagnetic Compatibility your thing? The Phoenix chapter of EMC Society is presenting EMC Fest 2002, with guest speaker Dr. Clayton R. Paul, Professor of Electrical Engineering at Mercer University, Macon, Georgia. EMC Fest 2002 will be held on March 11, 2002 at the Embassy Suites Hotel in Tempe, Arizona.

Student Paper Contest
The Tucson Section will be running a student paper contest with cash prizes! First place will get $250, second place $175, and third place $75. Presentations and judging will take place on March 30th but you must notify us of your intent to compete by March 18th and have five copies of each paper submitted in the IEEE format by March 22nd. IEEE format guidelines can be found at:
You must be a college undergraduate and an IEEE member to participate (If you’re not an IEEE member, get your applications in soon!) First place goes onto the IEEE Southwest Area meeting in Phoenix on April 13th for a chance to compete regionally. For more information contact Dr. Hal Tharp at 621-6201, Tovan Adams at 545-6759, or Erin Hogbin at 794-7520. We’re still working out the details but rules and format should be available soon on the website.
Do you want to become a senior member of the IEEE? The IEEE wants to promote qualified candidates to senior membership! If you have 10 years of professional experience plus five years of significant professional performance you are qualified for a senior member upgrade. Educational experience such as a bachelor’s degree in an IEEE-designated field counts 4 years to that number, a masters degree counts 5 years and a doctorate counts 6 years. In order to find out more, point your web browser towww.ieee.org and search for senior membership!
