Body Heat to Charge The Battery

Cell phone battery died on the way, seems to no longer be a problem. A new technology called Power Felt claimed could convert body heat into electric current, so the battery can be recharged at any time. The technology was developed by researchers at the Center for Nanotechnology and Molecular Materials at Wake Forest University.

Felt the power itself is made of carbon nanotubes is very small, and locked in a flexible plastic fibers that resemble fabric. This technology uses the difference between room temperature and the temperature of the body to create energy.  "We waste a lot of energy in the form of heat. For example, re-absorb the remaining energy is discarded car can help save fuel and generate power for the radio, air conditioning, and navigation systems," said Covey Hewitt, researcher and graduate of Wake Forest University.

"Generally, thermoelektrik is not yet fully developed technology to harvest energy, but in addition, there are many opportunities in this technology," he added. Felt Power technology can be applied to many things, including installing the car seat to increase the battery and other electrical needs, isolate or collect heat from the pipes under the roof of the house to offset the cost of gas and electricity, and put it on clothing or devices to monitor sports performance .

But the high cost of such technology to make it still harder to use in consumer products. Standard thermoelectric devices using bismuth telluride compound, which is much more efficient to convert heat into electricity in a variety of products, including refrigerators and CPU. But researchers say the cost could reach USD1, 000 per kilogram.
