Charge the mobile phone to walk
New developments are mixed: useful, useless revolutionary advance outdated and ill-thought out. This formulation carries a very useful idea, but its implementation, in our view, leaves much to be desired.
When knee bail produces electricity from energy Walking rights by requiring modest additional effort. This generator can be used for charging user portable devices: from mobile phones to medical implants. Hi Donelan (Max Donelan), a scientist from Simon Fraser University in Canada, which was developed by the device, argues that the generator does not require significant additional growth efforts, as active phase of the seizure of power is in the braking phase of each step.
This phase takes place at a time when already raspryamlennaya leg slows their movement, immediately before footsteps regards land. If we talk numbers, effort grows by about 20%. The power generated generator is 5 Watts. Let us hope that this undertaking is not anxiety in Lety, and developers improve the appearance of the generator as well as its size.
