1. We have a nuclear treaty with Iran. If Iran "cheats" what type of nuclear weapon will they likely build? How will they get the materials? What will be the bomb's yield in tons of TNT? Will the Iranians need to test the bomb before using it? How does such a bomb's yield compare to the hundred or so thermonuclear weapons that Israel is presumed to have.
2. What is the purpose of a nuclear reactor? How does it work? What are the potential dangers? Can a reactor blow up like an atomic bomb?
3. Electricity and magnetism seem different, but electricity can create magnetism, and magnetism can create electricity. Describe how this is done. Give examples illustrating how this is used in practical applications.
4. What are the advantages of solar power over use of fossil fuels? If a kilowatt of energy per second falls on a square meter, how much falls on a square kilometer. How much can we hope to recover from a square kilometer with current technologies? How does this compare with a gigawatt coal fed power plant or a gigawatt nuclear power plant?
