Researchers of the Finn VTT Technical Research Center have come close to mimicking some of the nature because of the development of sun and 3D printing technologies. They have developed some very decorative prototypes called "energy-efficient wood".
The leaves of the tree extract and store the sun, which are suitable for feeding smaller machines and mobile devices. They can be used indoors and outdoors and use the kinetic energy of the environment, such as wind and temperature changes. 
How do they work?
Tree leaves are in fact organic organic solar cells that are printed with proven mass production techniques. Each letter has a separate energy converter, which results in a multi converter system that allows you to collect energy from various sources such as solar, wind, and temperature.
The more solar cells you have on a tree, the more energy you can collect. Tree trunks are produced by 3D printing using wood-based biocomposites. They can be produced massively and reproduced in endless numbers.
