Because getting in the festive mood doesn’t have to cost the Earth… 

Brussel Sprout Christmas Tree

We bloomin’ love Christmas and now the tree’s up in the office we’re feeling very, very festive indeed. But we always do worry about the countless fairy lights adding a big ol’ whopper onto our winter electricity bill! Which is why we love this project that uses brussel sprouts to power Christmas tree lights!

Dreamt up by a team from The Big Bankg UK Young Scientists and Engineers Fair, 1,000 sprouts were linked together to make a vegetable battery which power the lights of a tree at the South Bank in London.

The battery works by putting copper and zinc electrodes between each sprout, creating a small reaction between the electrodes and each sprout’s acidic content.The Christmas dinner staples are then grouped together into five energy-giving cells, harvesting the energy created by the reaction and delivering 63 volts (or just the right amount to power the tree’s twinkly LED lights).

Love them or hate them, you have to admit this is pretty darn cool!

GC articles show you one of four ways (the one in bold) to live greener…

/ Be a winner (not a binner) /
/ Turn up the style (not the heat) /
/ Love the trend (not the spend) /
/
Do it in public (not the car/plane) /
