An experimental setup, including the land and a new used steel construction could cost less than $500k. Someone could throw a couple million at it to control for humidity, temperature, airflow, etc, with all sorts of variety, and it could be a lot of fun.
If something like this could be made safe, I imagine there are applications in security and process safety in places like nuclear power, water treatment, any facility where you want to restrict access in an extreme way. I'd imagine that it would never be safe, any discharge is going to fry whatever completes the circuit.

That's the kind of projects I'd fund if I were a billionaire, not trying to buy the biggest yacht …
I worked briefly in a factory where they had these giant rolls arriving daily... they were put onto a machine that would spool them off onto smaller rolls (say 100ft) and chop them. It's definitely something commonplace.
When they still did, they had an idea submission forum. I did post it there and the moderator responded with something close to "it's been submitted, not interesting, just try it yourself". I'm still annoyed at them for that stupid response.
