A highly futuristic concept of a laptop that bases it’s charging system in the same water-soaking abilities of the bamboo by the designers Seunggi Baek and Hyerim Kim. The Plantbook system uses an external water tank, hence the Plantbook continuously absorbs water when soaking it in water and generates electrolysis using power stored in a solar heat plate installed on the top. In this process, it is operated using hydrogen as energy source and discharges oxygen. If you put it into a water bottle while you don’t use the laptop, it automatically charges a battery and discharges oxygen.
