Discussion Energy

Discussion 1

In the last 1800s, there was a huge battle to determine what kind of electricity was going to light the world. On one side of the fight was Thomas Edison who insisted that DC was going to light the world and on the other was Nikola Tesla who thought AC was the better way.

From what you know about the two forms of electricity.

• Name advantages and disadvantages of each type
• What sort of tactics were deployed by each side to convince people their way was better?
• Why did Nikola Tesla eventually win the war?
• What would the world be like if Thomas Edison had succeeded, and power were supplied by DC instead of AC?

• What are some advantages and disadvantages associated with nuclear energy?
• List some concerns given by groups opposed to the building of these new reactors and cite some responses to those concerns.

), in particular rising seas will not only drown coastal sections of the city but will disrupt our local supply of drinking water.

Based on what you have learned so far from this class, discuss the following: 

• Explain where the drinking water from South Florida primarily comes from and why would rising sea levels disrupt this supply?
• What efforts can be made and are being made to mitigate the effects of rising seas on our drinking water?
• If you were a local politician, what advice would you give to state and federal officials on the best way to ensure residents in South Florida had a steady supply of drinking water for many years to come?

Discussion 4

The idea of sending people to Mars in hopes of colonizing the planet has long been out of the realm of possibilities but big thinkers like Elon Musk are determined to keep trying (linkLinks to an external site.).

From what you have learned from this class:

• Why is Mars considered so inhospitable?
• What would be needed to ensure humans could survive on Mars? In particular, where would we get our food, our oxygen, our water and our energy?
• If you were tasked with sending people to Mars, give a time-line of how they would get there, what would they bring, how long would they stay and what advice you would give anyone who wanted to go?
