World's First Sprout-Powered Battery Just Lit Up a Christmas Tree

With Thanksgiving coming up, it's almost time for households to ask the perennial question: What do you do with the sprouts nobody wanted to eat? Now we have a new answer: Wait a few weeks, then use them to power your Christmas tree

That, at least, appears to be the message from a new project installed on the South Bank of the Thames in London on behalf of the the Big Bang UK Young Scientists & Engineers Fair: the world’s first battery made entirely of Brussels sprouts. Some 1,000 of the rotund green veggies are being used to light 100 LEDs on an 8-foot Christmas tree.
