http://mobminresources.org/story.php?title=this-tiny-generator-can-power-wearable-devices-using-your-body-heat Body heat-absorbing generators made from inorganic materials like this have higher power output than ones made from organic substances, making them the better choice. Problem is, they're also typically larger and more rigid. This creation addresses both issues, and the glass fabric even minimizes heat loss and maximizes output, as discussed in the paper the institute published recently. Tue, 15 Apr 2014 06:12:46 UTC en
