Let's pretend batteries don't exist and we cannot rely on wind and solar. Using MacKay, the reading, the notes, and The Internet, make a case for would use nuclear fission and geothermal power. For geothermal power, 1. Pick a location. Anywhere you want. 2. Calculate the depth required to get a "hot" side of 500C based on the notes/reading/internet. Cite you work 3. A useful equation for modeling the heat flow through rock is where Q is heat in W/m^2, AT Q = k Z W k is the thermal conductivity in units of m-K z is the average thickness (in meters) the heat as to traverse to get to the geothermal pipe, and AT is the temperature gradient between the hot rock and the cold incoming water/working fluid. Prove to yourself that this is dimensionally consistent across the =, and then 4. Look up relevant values of k (cite please), and determine the contact area required to hit to 1 MW heat in the hole. For nuclear power: Make a policy argument, for or against, nuclear, in 3 paragraphs, on why nuclear is or is not a more sustainable and environmentally sound choice than geothermal power.
