Tom vales is a professor in the Suffolk university. Recently, he came in to give us a presentation.
Tom holds annual presentations for electrical light shows to be presented and along with his fellow buddies, does experiments and tricks-but he remembers to wear his ear plugs because the crackling is so loud it could even damage your hearing. The four models he focused on: Jean Peltier’s thermoelectric cooling method, the hot-air engine, the Piezo effect, and the Mendocino motor.
Vales lectured us on was the Peltier effect. Peltier made an astounding discovery when he “joined copper wire and bismouth wire together and connected, then to a battery.” While one of “junctions of the two wires” got hot, the other got cold. Like this he created the effect that could power a low efficient refrigerator. The principle that is most important about this experiment is that “In essence, the Peltier effect shows that electricity can cause a heat difference at the junction of two different metals connected together.” Vales told us this is what beer coolers essentially use as a function to keep beers cool.
Her experiment was very interesting and fun to look at. Vales talked about the inventor of power grid, Nikola Tesela (10 July 1856 – 7 January 1943). Teselas dream was wireless power transition and he made it happen. When he turned on the tower, its substantial wiring was then routed through a large high-voltage and when professor Vales held two light bulbs near it they both light up.
The last part of Professor Vales presentations was about eh Tesla Coil. The machine that he brought in was very cool. It was an example of what a powere grid is and in his demonstration he held different objects up with the machine to show us how it worked and how it generated electricity. This was definitely a crowd pleaser everyone including myself was very amazed with with part of his presentation. Tom Vales presentation was very informative, interesting and a whole lot of fun to watch. He definitely helped us understand the different types of energy technologies that are out there that are much more sustainable.
