Human body or anything that ejects warmth for its functioning
really wastes a big amount of energy in form of heat. Can this
dissipating energy be harvested and used to run an electric
device? A team of Wake Forest University scientists have done a
good job in this regard. They have developed a thermoelectric
device, called the Power Felt, to gather power from heat,
whether it originates from human body, roof tiles or even a
wound wrap. To generate a charge, the Power Felt utilizes
temperature differences between the body and outer area. In
other words, if the device is put to generate power from human
body heat, it creates the charge from the difference between the
temperature of the body and the temperature of the room. The
fabric-like device is made locking up tiny carbon nanotubes in
flexible plastic fibers. Well, this textile device can be
designed to use inside a cloth or with anything that emits heat.
According to Corey Hewitt, a graduate student of the Wake
Forest, thermoelectrics has been an underdev
