NEXT MEETING___________________________

Monday, Apr. 20, 2009 - Noon - DOUBLETREE HOTEL, Second Floor (407 Chestnut St., Chattanooga, TN 37402)

“Removing heavy metal contamination from water and air” – David Vernetti, Steward Advanced Materials

Recently there have been many news stories about heavy metal contamination in our water and air.  In some cases, contamination has existed for a long time, but most of us are unaware of the problem.  Steward Advanced Materials, Inc. has developed chemical additives which help remediate and treat water to adsorb these contaminates.  The company is a Chattanooga-based manufacturer of ceramic and metal powders for use in electronic, industrial, defense and environmental applications.

David Vernetti, the General Manager of Steward Advanced Materials will describe the processes and chemicals his company has developed for removing mercury and other heavy metals to low part per trillion (ppt) levels, and other methods for removing arsenic and selenium.  He will also describe how contaminates can be disposed of as non-hazardous waste, after they are adsorbed. David has been with the company for the past ten years and holds a Bachelors and Masters degree in Ceramic Engineering.

 

FUTURE MEETINGS________________________

Monday, Apr. 27 - Noon - “Exciting stories of Thomas Edison’s inventive life” - Jim Frierson, great-grandson of John Kruesi, will present the Kruesi Legacy and an inside story of Thomas Edison's laboratory and Edison’s early days of invention at Menlo Park. John Kruesi was Edison’s head machinist through his Newark and Menlo Park periods. Mr. Kruesi translated Edison’s numerous rough sketches into working devices.

Frierson will discuss the details of Edison’s inventions and Kruesi’s work as a key player in Edison’s success as an inventor.

Speaker: Jim Frierson, ATTI

Meeting Place: DOUBLETREE HOTEL

 

Monday, May 4 - Noon - “Solar Energy:  Solution to conservation” – With a renewed emphasis on conservation and using renewable energy, more and more people are looking to solar energy as a solution.  For those solutions to become a reality, trained and certified installers will be needed to support this growing industry.

Allan Gentry, Instructor, Interim Dean and Chair of the Technology Department at Cleveland State Community College will speak on Solar PV Installer Training and Certification.

Speaker:  Allan Gentry, Cleveland State Community College

Meeting Place:  DOUBLETREE HOTEL

 

Monday, May 11 - Noon - “A visionary transportation system that could change the world” - Personal Transportation remains a key infrastructure in the economic framework of any nation.  With today’s public concerns about economical energy requirements and foreword momentum in consumption, and responsible environmental stewardship, Vertical Axis Integration Company (VXICOM) will present a new approach to transportation and energy storage.

Speakers:  Steven Rasor, principal architect and founder of VXICOM, a Chattanooga enterprise; and Stephen Smith, Chemical Engineer, Coalsmith Consultants

Meeting Place:  DOUBLETREE HOTEL

 

PREVIOUS MEETING_______________________

Dr. Kazemersky, Professor of Engineering at UTC introduced UTC students presenting the UTC Capstone Projects.

Justin McBath presented Conversion of Saturn Vue to operate on either gasoline or hydrogen fuel.  5000 psi tank pressure was selected to minimize space and weight requirements.  Stainless steel lines with Swagelok fittings were used to reduce the corrosion effect.  Justin’s team budgeted $14,000 for the project, and $18,500 was expended due to scope and equipment changes that materialized during the design development.

John Ozbek talked about an H² production facility.  His group studied codes, safety, H² demand, component selection, performance, and economics.  John’s team was required to produce 2KG H² per day and store 10KG of H² for use in the Saturn testing and follow-on projects.  The calculated cost to produce hydrogen was $53.77/kilogram based on data obtained from the demonstration production facility designed for limited H² production.   It was noted that H² cost was very sensitive to capital cost of the production facility. 

Michael Murphy discussed the Inductive Power Transfer Project, which is testing rapid charging (3-5 minutes) of batteries or ultra-capacitors.  The charging system used Wampfler IPT technology.  A typical charging system consists of a coil imbedded in the pavement and powered by the local power grid.  The energized coil will induce a current in a receiving coil on the bus and charge the battery/ultra-capacitor pack of an electric bus.  Greg Burnett explained the design and fabrication of the Mini Baja all-terrain vehicle, using a Briggs and Straton engine with a hydrostatic transmission.  The team designed the suspension, transmission and drive train components.
