Dead Star, a Sculpture by Michel de Broin

"Dead Star" is a sculpture by Michel de Broin made from used up batteries:

Dead Star is made from residual battery at the end of their duty. Left to itself, the sculpture will slowly cool down since there is no longer electronic activity taking place in it. The hundreds of batteries were once used to power appliances before they finish their cycle in a recycle facility. Retrieve from death, they were assembled again in this whole structure.
