Reminiscent of the WPA-built outhouse we had on a farm
my dad bought right after WW II started.
The corrugated tin roof spaces between it and the frame
allowed escape of "essence".
Newsprint and the old Sears catalog served as "Charmin".
The "accumulator" was a hole in the ground beneath the
precast concrete floor that made it easy to discern which
was one's buttocks.
I see no connection with the Joe Cell here.
Close to a Faraday Box. though.
