I am a farmer with giant water pumps and center pivots that run on 3 phase 480 volt power. One of my pumps has 85 horsepower. I wonder if I could wire up some sort of custom made tea kettle and get water to boil in five seconds?

You could run (10) of these 9kW 480V three-phase immersion heaters [0] in place of your 85 HP motor, assuming ~110A FLA @ 480V = 91.5kW. The 9kW immersion heaters are 10.8A each at 480V three-phase (would be 75A if it was 120V single-phase!)

Just make sure you have somewhere for the steam to go, it takes up a bit more room than water ;)

Is your three-phase a corner-grounded delta service? I’ve never seen one in the wild but I hear they’re used for three-phase ag service drops that are strictly used to run motors. A and C are tapped normally on the secondary but the B phase is bonded to ground and also a line conductor, conductor color is white for B phase instead of orange.
