I was on a wine tour and on the way back to the hotel looked out the window and was gobsmacked. “Woah... that’s the Spruce Goose! The Spruce Goose is here!?!”
Cancelled the next day’s tour and hit up the museum instead.
It's called a battery isolator, and it's basically a monster diode from the alternator to the battery. Very common setup for RV's, etc.
I had one set up in my Jeep so that it would charge the deep cycle marine battery for my fishing pontoon's electric motor... way, way faster than anything you plug into the wall.
As a long distance shooter, and lover of technology, I would most assuredly get a lot of joy out of this.
Also, you'd be incorrect about this doing the hard work. They add the concept of "windage" almost as an afterthought, and I can tell you that at long distances, it is anything but.
In long distance shooting, pulling the trigger is the easy part.
