Your box springs are indoors as I understand it, which is one place it could be a valuable discovery, if it provides an improvement over the ground situation for an indoor setup.
The next thing to ask is what could be done with a buried mattress spring out back?
The extra metallic dimension of a mattress spring might bond better with the earth than simple radials laid on the top layer.
What kind of metal is that in those springs?
What is a good way to bond a good connection to it?
