Use Your Body Heat To Charge Cellphones
Wake Forest University scientists have developed a thermoelectric device called the Power Felt. It is made of carbon nanotubes wrapped in flexible plastic fibers to gather power from heat, no matter if it originates from human body or a roof surface. Power Felt uses temperature difference between let’s say the body, and outer area to generate the charge. If and when the amount of power generated can be raised to some meaningful numbers, this technology can become a lifesaver to charge pretty much anything in harsh environments.
