Poseidon Energy employee ID card

The Poseidon Energy employee ID card is a holodisk in Fallout: New Vegas.

Locations
It is located in the HELIOS One solar collection tower, past the second Mister Gutsy following the top floor. At the second stairwell past the cots, enter the room directly to the right at the bottom of the stairs, then turn right and go down the corridor. Then, turn left and enter the door to a room filled with crates. The ID card is in the southwest corner of the room, on the floor by a skeleton.

Uses
Can be used to activate a repair robot called PYTHON in the solar collection tower to complete the That Lucky Old Sun quest, if the player's Science skill is below 45.
