The clothes we wear can generate enough energy to charge our mobile phone batteries, when powered with technology.
Nanotechnology has a better answer to energy efficiency and conservation. Professor Li-Wei Lin at University of California, Berkley is working along with his team to enrich our clothing with more features, to be able to keep our portable gadgets like our mobile phone charged with energy generated by body movements. His idea is to intertwine electric generators into clothing fibre. Thus allowing the energy generated from our body to be utilized for a purpose rather than being wasted away.
Earlier, Sciencedaily reported about the Stanford Engineer Yi Cui, is working on a similar concept with a different approach. He is experimenting to code nano material into common cloth with nano infused ink. Thus building a battery that will be embedded into clothing which will act as a energy storing device.
