I was quite amazed of this solar powered furniture making machine called The Idea of a Tree by Mischer’ Traxler. Each product has its shape and color formed and determined depending on the amount of sunlight by the time certain product is manufactured. The machine works out by drawing a thread through a tank with dye in it then followed by a tank with resin and wrap it around a mold that is rotated using a solar-powered machine. The machine has the ability to produce benches, containers and lampshades. Items made during cloudy season are darker and thinner. The machine automatically starts at sunrise and stops when the sun sets.
