Body heat harnessing jacket – Warm up while you power up

by yogesh


Alternative power that’s free to harness is going to be the rage in the future. Be it the wind-up mobile phone or the shoe charger. How about, adding a jacket that can charge your mobile or other gadgets on those cold days. The Berkeley Lab at UC Berkeley plans to lace silicon nanowires into a power-jacket. The excess heat from the human body would be used to recharge portable electronic devices, such as cell-phones, PSP’s and laptops. The process being developed is called “electroless etching,” where rough silicon nanowires are synthesized with silver ions on a flat wafer surface. These wafers would be woven into coats and the excess warmth given off by the body would be transformed into energy.

Scientists are just beginning to find a way to make them efficient enough to prove practical. That’s because silicon is a poor conductor of heat at room temperature. The lab has found a solution, reduce the size of the nanowires and combine a flat surface with a heat conducting material. Let’s just hope this technology sees the light of day in those trendy clothes shops. What say GUCCI?
