Knee device makes phone charging a walk in the park

They should build thing like those everywhere their movement on our body the most(On the arm,Neck):P

yay! we wont have to pay for energy

would it not make more sense to have this in the sole of the shoe as a energy absorption unity? and maybe if the cloths had micro fibers and magnets woven into them the whole body would act as a generator.

This is great! People could use it to generate enough electricity to light crack pipes anywhere. The money they would save on lighters would pay for thier rehab.

just think about it if this was in fact in your clothes. it could be on a smaller scale. and there could be a charger in your pocket that charges

"I am Galstaff, Sorcerer of Light.  This knee device could be used to generate electricity while a person is walking. I'm attacking the darkness."

A guy in England has pioneered self powered traffic lights that get their energy from vehicles driving over springy magnets at the lights. I was thinking that the same idea could be applied in busy foyers and shopping malls, schools, etc to generate electricity for the buildings foyer.
