Brain Teaser Challenge - November

by Butch Shadwell

I was just watching one of those reality shows on TV. This one had a dozen American city girls trying to win the heart of an Australian fellow from the outback. It was very amusing. These girls came from all sorts of backgrounds and educational experience.
Some of the young debs were upset that they could not plug in there hair dryers while living in the bush. One even had to redo her own nails … a first for her. As luck would have it, one girl had been in the Girl Scouts and one of her merit badges was in electricity. The producers of the TV show found a car battery and a power inverter to aid with the hair blowing emergency. This inverter produced a 60 Hz sine wave at 120 vrms, 15A max. The instructions said that it will not handle loads with a PF less than 0.9. If the hair dryer says that it draws 1000W or 1200 VA, will the inverter carry the load? For extra credit what is the angle between the current and voltage waveforms on this appliance? Our Girl Scout got it right.

Future Cities Needs You

The Future City Competition is an amazing program that introduces 7th and 8th grade students to the field of engineering. The students plan, design, and “build” a city of the future then present their city to a panel of expert judges at a local competition held in January. I am the regional coordinator for the Future City Competition Hampton Roads VA region and I am hoping one of you (or your colleagues) can help us out.
Eaton Middle School in Hampton has registered to compete in this years competition. However, they need help finding an engineer mentor.
Typically, an engineer mentor can expect to provide approximately 20-40 hours of assistance to the student team over the competition period (from now through January). However, that time can vary based on the students’ needs and the engineer mentor availability. You might also consider “tag-teaming” with another co-worker/engineer to meet the teams needs.
You can find more information about the role of the engineer mentor in the handbook here: www.futurecity.org/docs/2009_Engineer_Mentor_Manual.pdf
And about the Future City Competition itself here: www.futurecity.org.
If you are interested in being a mentor, please contact me either by phone (757-728-2038) or via email [sgriffett@hampton.govsgriffett@hampton.gov ] and I will answer any other questions you might have and put you in direct contact with the teacher.
Please feel free to forward this information to anyone you know who might be interested.
If you are not able to be a mentor but might be interested in serving as a judge at the competition, just let me know!
Thank you for your time and consideration and I look forward to hearing from you!

2009 IEEE Green Technology Conference

Seeks Technical Papers

Call for Papers: 2009 IEEE Green Technology Conference
NEWS from IEEE-USA
1828 L Street, N.W., Suite 1202
Washington, DC 20036-5104

WASHINGTON (9 October 2008) -- The first IEEE Green Technology Conference will examine alternative energy sources and energy-reduction technologies and their potential for helping the world meet its growing demand for energy, while reducing carbon emissions. Conference organizers are seeking technical papers on current and emerging technologies in environmentally friendly energy sources, and on ways to better manage our energy resources.

Accepted papers will be published by the IEEE and presented at the 2009 IEEE Green Technology Conference (www.ieeegreentech.org) at the Holiday Inn Hotel Towers in Lubbock, Texas, USA, 16-17 April 2009. The conference will precede the annual IEEE Region 5 Meeting.

Topics of interest include the technical and policy challenges of renewable energy sources; alternative vehicle power sources; home automation and energy management; commercial energy management strategies; energy usage reduction; and integration of green energy sources into the existing power grid. The social and economic implications of renewable and reduced carbon emission energy sources will also be examined.

Alternative energy keynote speakers will address these challenges, as will panel discussions and presentations on technology advances.

With increasing concerns about fossil fuel costs, supplies and emissions, people the world over are more closely examining the commercial viability of other energy sources. These include solar, wind, nuclear, geothermal, hydro and biomass, among others, as well as alternative vehicle power sources such as fuel cells, gasoline and liquid natural gas electric hybrids and plugin hybrid electric vehicles.

Authors are invited to submit abstracts by 31 December 2008. Accepted authors will be notified 31 January 2009, and full 8-page papers in the IEEE conference format are due by 1 March 2009.

(www.ieee.org/portal/cms_docs/pubs/confpubcenter/pdfs/samplems.pdf).

Submissions must describe original work not previously published or currently under review for publication in another conference or journal. Send your submissions to green.tech09@gmail.com.

The 2009 IEEE Green Technology Conference is sponsored by IEEE Region 5, the IEEE South Plains Section and IEEE-USA.

IEEE-USA advances the public good and promotes the careers and public policy interests of more than 215,000 engineers, scientists and allied professionals who are U.S. members of the IEEE. IEEE-USA is part of the IEEE, the world’s largest technical professional society with 375,000 members in 160 countries. See www.ieeeusa.org.
