According to the designers ”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”.
Televisions as thin and flexible as a sheet of paper could be on the way, thanks to a new technique for printing electronics. At the moment, mass production of such devices is held up by the difficulty of manufacturing at low cost in ambient conditions. In order to create light or energy by injecting or collecting electrons, printed electronics require conductors, usually calcium, magnesium or lithium, with a low-work function. However, all these are chemically very reactive, oxidizing and stopping working if exposed to oxygen and moisture.
By Louis Bergeron Anatoliy Sokolov A single crystal of the new organic semiconductor material shown in polarized light. It is approximately twice as fast as the parent organic material from which it was derived.
This concept sketch illustrates the highway-to-car electric charge. The actual electric field is invisible. Even if battery power improves to the point that vehicles could travel from Boston to Washington on a single charge, a critical problem remains: charging up electric vehicles takes forever. After a battery is exhausted, it can take more than 10 hours to fully charge a car. That's no comparison with the 3 minutes it takes to fill your car's gas tank.
