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. | Your team was able to shut down the hawkion accelerator before it could blow itself up, and possibly take Lakeview with it.

- | 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? | + | 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.
