 ==== Project: Design a Defib ====
-Your team was able to shut down the hawkion accelerator before it could blow itself up, and possibly take Lakeview with it.  But the beam dump that absorbed the hawkions is now highly radioactive.  You need to put shielding around it before anyone receives too high of a dose, but no one can go near it.

-Solomon Tobb, the ingenious intern, suggests that project I.A.N. could save the day.
+Solomon Tobb, the ingenious intern, suggests the project I.A.N. could be the answer.  He explains that I.A.N. stands for Intelligent Artificial eNtity: a robot.  I.A.N.'s systems should withstand the radiation long enough to put the shielding in place, but unfortunately, you used both his primary and backup batteries for emergency power to the accelerator so I.A.N. is completely shut down.
-The Artemis 13 is on it's way back to Earth and currently is hanging in lower Earth orbit. You and a team of scientists have been desperately re-wiring the spacecraft circuitry to get home. While soldering wires, your android co-pilot Johnny 5 begins to malfunction, it is essential that Johnny 5 not lose all power as he controls the landing sequence to reach the planet's surface. Melissa Lewis, the team leader, mentioned that in a [[https://www.youtube.com/watch?v=H-vXydxLZMk|training video]] she saw back in the 80's call "Short Circuit 2" a model like Johnny 5 was brought back to life using a defibrillator.

-You run to the medical bay and grab the defibrillator and rush back to Johnny 5. 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 Johnny 5 by shocking him with faulty equipment, you decide against pressing the button and shouting "clear." You need to save Johnny 5. Using your knowledge of electromagnetism, you know you can create a makeshift piece of equipment to be able to stabilize Johnny 5.
+There's no defibrillator at FTOE, but using your knowledge of electromagnetism, you know you can create a makeshift piece of equipment to be able to restart I.A.N.  You run to the laboratory stock room, and manage to find several sheets of aluminum, various paper sheets, some electrical tape and wires, and a pair of all-purpose scissors.
-You run to the limited "stock room" on board, only to discover limited supplies. You manage to find sheets of aluminum, and various paper sheets, some electrical tape and wires, and a pair of all-purpose scissors.
+The paper sheets are 0.5 m wide, 2 m in length, and vary in thickness (2 mm, 1 mm, 500 μm, 50 μm, 1 μm, 0.5 μm). The aluminum sheets are 0.80 m in length, 0.5 m wide, and 0.3 mm in thickness. The stock room also has a high voltage power supply of 30 kV.  Your device must be able to deliver a rapid jolt of 360 J to I.A.N. in order to restart him. Can you put something together to get him working and save the day?
