Kneepads to recharge our gadgets
Bring the shipper of gadgets with us all day it seems that one option is to be permanently connected to the hopes that the battery was not invented perfect. Doing so could take part in the discovery of a few scientists from the U.S. and Canada, who have invented a device mounted on the knee is capable of storing energy as we walk. The news has already come out in the journal Science.
In tests, an apparatus in each leg of volunteers managed to generate a total of 5 W, which gives us energy to run up to 10 mobile phone. The experiments were conducted with people walking on tapes running at a normal pace, so that spending does not exceed the energy generated. At the end has shown that these can be generated with just a step 5W traditional and effortlessly by the person. It takes for this energy that is wasted at the end of the balancing leg. Even a person running could generate up to 54W.
The experiment opens the way back to something very always wanted: that our body, with daily activities and without imposing extra effort for us to achieve generate energy to recharge gadgets for example. Applicators may be less interested in giving the feed pumps insulin in diabetic patients.
Tests conducted so far did not take this kind of energy directly from the body but consists of shoes or backpacks, but had never achieved such good results.
