Not to sound alarming or anything, but apparently, we've only got a decade or so before our planet runs clean out of indium. Thankfully for us, a team of researchers at the Max Planck Institute for Polymer Research in Germany are purportedly onto a replacement. For those in the dark, indium is a critical resource in "creating solar cells, LCD and other devices which must have transparent electrodes to carry out their function," but the aforementioned crew has seemingly been able to take graphene ("single layer 2D sheets extracted from the common material graphite") and build an acceptable alternative. The creation is 80-percent transparent to visible light and 100-percent transparent to infrared light, which could actually lead to solar cells capable of soaking up even more energy from more of the EM spectrum. 'Course, there's no telling how close this discovery is to being commercially viable, but we suppose we could always resurrect RPTVs and rely solely on wind farms for renewable energy if necessary, right?

Graphene could be used in creating solar cells, LCDs
