+==== Project 6B: Design a Defib ====
+You are stationed onboard the spaceship Artemis 13 currently hanging in lower Earth orbit. You and a team of scientists are testing the life support systems for extended space travel aboard the ship. During a training exercise, one of your fellow astronauts, Spurgeon Tanner, clutches at his chest and falls over. You, the talented Andrea Baker, recognize this immediately as a heart attack.
+You run to the medical bay and grab the defibrillator and rush back to Spurgeon. When you go to charge the defibrillator, however, you notice that the instruments are not reporting a proper charge. In order to not risk the safety of your fellow astronaut by shocking him with faulty equipment, you decide against pressing the button and shouting "clear." You need to save Spurgeon. Using your knowledge of electromagnetism, you know you can create a makeshift piece of equipment to be able to stabilize Spurgeon.
+You run to the stock room downstairs only to discover that it isn't fully supplied yet. This was supposed to be just a simple systems test mission. You do find sheets of aluminum, and various paper sheets, some electrical tape and wires, and a pair of all-purpose scissors.
+The defibrillator must be able to deliver 360 J to Spurgeon in order to stabilize him. Can you fix the instrument and save the patient?
+The paper sheets are 0.5 m wide, 2 m in length, and vary in thickness (2 mm, 1 mm, 500  $\mu$ m, 50  $\mu$ m, 1  $\mu$ m, 0.5  $\mu$ m). The aluminum sheets are 0.80 m in length, 0.5 m wide, and 0.3 mm in thickness. The defibrillator has a high voltage power supply of 30 kV.
