Christmas tree powered by energy-harvesting paving slabs

What better way to celebrate Christmas than by doing the environment a favor and keeping celebrations eco-friendly! This Christmas tree in UK got greener than just about any tree around, thanks to the efforts put into it all by a British company. The tree, set up in a shopping mall, is hooked on to energy-harvesting paving slabs that generate energy from people’s footsteps. The kinetic energy harvested is then converted into electrical energy, which in turn was used to light up this beautiful tree. Turning the Christmas spirit greener than ever, this tree cares along with it the holiday cheer as well as a eco-friendly message to the world at large.
