"free energy": mobile, wireless, off the line energy generated in small modules or cluster - a vision how electrical power supply could work in the future.
Single modules can be used as mobile energy storage or clustered with other modules as well. Modules are attached magnetically. Photovoltaic cells are generating energy, which is transmitted wireless through combined induction fields to other modules of the cluster, to the accumulator for storage or the OLED-layer for room lighting.
The leaf-shaped modules are building up an organic structure that integrates into every environment like a plant.
