TreeHuggers wanting a fun way to do some background research on advanced TreeHugging materials might do well to poke around the Comic Book Periodic Table of the Elements. That's where this TreeHugger (TH) found a lovely picture of a roll of Vanadium (V) metal, of the sort involved in Vanadium energy storage devices,and as recently featured here on TH. "Th" also means Thorium by the way. See: Thor...avenging warrior of TreeHuggers, after the fold.
