Solutions

 * Jump over to the middle island with the closed Steel Door Green. Place an Engineer under water next to the Green Switch on the left side.  He will flip the switch.  When the Steel Door Green opens, stay on the island, but get on the other side of the door.  Trash the Engineer and create a new one to flip the same Green Switch to open up the way to the Starite
 * This can be repeated with the Architect and Mechanic
