Phone + Your Pocket = Efficient Charging

This is probably the most efficient charging method I have heard of.

…In case of textiles, though, most attempts, so far, to integrate electronics involve patching sensors and resistors on to existing fabric.
The latest attempt tries to bring the electronics to the molecular level. The researchers coated cellulose and polyester fibers with ‘ink’ made from single-walled carbon nanotubes. The nanotubes are electrically conductive carbon fibers barely 1/50,000 the width of a human hair.
The process of dyeing with this special ink is similar to that used for dyeing fibers and fabrics in the textile industry, they say. Details of the method were published in a paper in the ACS’ Nano Letters journal.
The coating makes the fibers highly conductive by turning them into porous conductors. The treated textiles can then be used as electrodes and standard textiles used as separators to creates fully stretchable supercapacitors. Ordinary capacitors are used to store energy. Supercapacitors can offer turbocharge that principle such that the capacitor can be charged and discharged virtually…
