Abstract

Here is is proposed a solution to create power on a laptop computer using a piston-based approach. Piston are directly built-in into the upper part ( the monitor) of the laptop and slides to the bottom part (the keyboard). By opening and closing the laptop screen we generate power.

Self rechargeable piston-action laptop design

Computers are spreading faster than the power networks. One of the main challenge is to develop a computer able to recharge its battery without a power plug. For example,, solar panel over the case are widely used. But, since the sun is not always shining and since indoor solar charging is not feasible, it is also useful to add a manual mechanical recharging feature, such as a crank or a pedal.

    The problem is obtaining a good "ratio" between manual charging and laptop use.

Since we already have a moving and robust part into a laptop design, an hydraulic piston based approach is proposed.

    Piston are directly built-in into the upper part ( the monitor) and slides to the bottom part (the keyboard). By opening and closing the laptop screen the user generates power.

    Consider using the same work of a wind turbine. By an estimate made over mini-turbines and other very small energy harvesting devices, such as educational ones we may estimate an output of 2,5 to 6 volts per turbine, by consider the double turbine, and optimization of the components we may produce from 5 to 12 volt. This makes the solution suitable for netbook and low-consumption notebooks. Of course it must be taken in account to provide continuous power to the battery avoiding peaks and shortages.
