Although we highly doubt there will be a real life application of such a device any time soon, the Plantbook is definitely taking a step outside the box of traditional notebook concepts and designs. Designed by Seunggi Baek & Hyerim Kim, the Plantbook is inspired from the water-soaking abilities of a bamboo plant.
This device itself looks like a bamboo stick in which the 'screen' can be rolled in and out, splitting into two to become a virtual keyboard and a screen. As if the whole portability factor of the Plantbook wasn't cool enough, it charges itself using water! Much like a real plant, the Plantbook concept utilizes an external water tank and the process of electrolysis to produce electricity to charge the device.
We all know that water and computer hardware aren't exactly the friendliest of combinations, but the Plantbook definitely defies all logic in that regard. It may sound completely ridiculous, but the designers seem to have it all figured out:
“The 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. A leaf-shaped strap hanging on the top is made with silicon. It plays a role of a hand ring and a green LED indicates when the battery is charged. Using this LED, users can check how much spare capacity the batter has.”
Unfortunately it is just a concept, so don't expect to be carrying your laptop in a water bottle any time soon.
