The talk "Acoustical solutions to archaeological mysteries at Chichen Itza's temple of Kukulkan (2pAA3)" by David Lubman will be at 2:15 p.m. on Tuesday, November 16.
6) Making Energy from Vibrations
When one thinks of cleanly soaking up energy from the surrounding environment, solar and wind energy come quickly to mind. Geothermal and ocean-wave energy are also being studied for use in making electricity. But what about the vibrations common to many heavy machines?
John McCoy, an engineer at the Catholic University of America in Washington, D.C., believes a lot of energy can be tapped in vibrations which otherwise go to waste in the form of heat, noise and wear.
"There is no law of physics that precludes harvesting a significant percentage of all the energy contained in vibrating structures," he says.
McCoy will discuss some of the studies that show how vibration energy can be turned to good account, especially in the built environment, such as subways, bridges and buildings. Current vibration-harvesting devices generally rescue energy at the milliwatt level, but McCoy believes that recovery rates can be much higher than that.
The talk "Vibration energy harvest: A basis for novel technologies" by John McCoy will be at 2:15 p.m. on Tuesday, November 16.
Dr. McCoy has written a lay-language paper that describes this research in greater detail. It is available upon request and will be posted to ASA's virtual press room shortly before the meeting.
