This laptop called "Plantbook" is eco-friendly because it does not need electricity to charge its battery and be able to work, what it needs is water, basically you have to water the computer.
The charge of the battery has a way of doing it very similar to the photosynthesis of a plant, when it is rolled in itself it acquires the shape of a trunk, it is put in the container with water and performs an electrolysis thanks to the solar panel that it has installed on top.
In this way the hydrogen is separated from the oxygen, the hydrogen is what makes the computer work and the oxygen for the environment.
