This man is starving the electric eels by throwing his car batteries in here.
This place is not a place of honor. No highly esteemed deed is commemorated here. Nothing valued is here.
I found this really short run-down of how ionizing smoke detectors, which I did not know they were called that, function and how they differ from photelectric smoke detectors (I didn't know there were two gkinds either.

Where do you get a hold of 350 smoke detectors? Looks like it's right next to his foundation too. Insurance company is going to love that. They send drones and scour social media so how brave to post it.
Fire station. A friend and I got about 100, 150 they were throwing out because they were too old to be installing in people's homes. We'd disassembled maybe a quarter of them before reading enough to understand we weren't gonna be making any kind of nuke with the bits of americium we were pulling out.
Unironically, to dispose of complicated* wastes well, you want to find some place that groundwater doesn't really drain out of, then put all the waste in a deep pit there, ideally sheltered from wind. Then you leave it for the future archaeologists or prospectors to find.
*Anything that's not compostable, combustible, or practically recyclable.
But you don't want to do this within 100 meters of a living space, and definitely not as a Groverpit right underneath your foundation!
If it was brown instead of iridescent green, I would've believed it. Tame by Florida standards.
It would probably be pretty effective at keeping pests away if done near the house though
