Scientists in Finland Have Created 3D Printed Trees that Harvest Energy

Here’s a prototype worth getting excited about: scientists at the VTT Technical Research Centre of Finland have developed a “tree” that harvests energy. They are 3D printed, and, according to the manufacturer, can collect power in a number of ways. The leaves are “printed organic solar cells,” generating electricity not only from sunlight, but wind and temperature changes as well. The leaves, which each have their own power converters, can be used to power small electronic devices such as mobile phones and LED lights.
