‘Light up the world, Reduce-Reuse-Recycle’
Based on one of my favourite Ghibli animated films, ‘Laputa’ and the topic of biofuels, made this robot (representing the advanced technology) holding a light bulb (the Earth) which is being lit up by the energy generated by the banana peel the boy (the new/future generations) is placing into the compartment at the back of the robot.
