We have been learning about various types of energy so our professor thought it would be beneficial to have Tom Vales come in and speak to us. When entering our class he had various items that i had never seen before and he informed us of what they are, what they do and some of he history behind them.
The first item that was introduced was the Stirling Engine, created for steam engines. In the past steam engines would blow up and injure or kill many people, because of this Sterling created the hot air engine. For this machine to generate energy it requires different temperatures on the top and bottom plate. The difference of temperature must be about 7 degrees farenheight. The machine that was displayed in our classroom was placed over a cup of hot water, and when heat rose it was trapped between the cup and the machine which created the power for it to run. It could be anywhere from 50-80% efficient. Many cars use technology like this for beverage heaters. It originally ran on oil and coal, but we have been running out of those fossil fuels, and they are not good for the environment.
He also showed us the Tessla coil which was created in Serbia by Nikola Tessla. The power outlets were also created from Tessla. The Tessla coil is a wireless transmission of energy that will work even though a cork, and can light a lightbulb without the lightbulb being inserted into a socket. the Tessla coil has argon which causes a purple glow.
Tom Vales was a very enlightening speaker and I appreciate that he took the time to speak to our class. The knowledge that he shared was very interesting and he made it very enjoyable incorporating humor throughout his whole lecture.
