Dead Star

Thursday, January 7, 2010

I saw this funky piece this morning on Dinosaurs and Robots.

Michel de Broin

It was made by artist Michel de Broin whose website explains:

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. Retrieved from death, they were assembled again in this whole structure.

Plastic bag batteries

Sunday, December 20, 2009

Scientists have come up with yet another way to upcycle plastic bags, this time into nanotubes that can be used to make batteries. According to Discover magazine, however, it’s a pricey process.

It involves an expensive catalyst in cobalt acetate, which is not easily recovered, to convert the high or low-density polyethylene (HDPE and LDPE) into carbon nanotubes. But if the nanotubes are then used to make lithium-ion or lithium-air batteries, that might overcome this problem, since these batteries are already recycled at the end of their use to recover cobalt.
