Electricity from Body Heat

Scientists have developed a more efficient thermoelectric silicon nanowire that could be used in generators to covert heat from various sources, including the human body, to electricity. While the physics of the new nanowires are not fully understood, the results are. Previous nanowire-based converters were not efficient for production, but if the promise of these new nanowires hold through, we could see countless applications hitting the market. The US DOD & DOE would definitely be interested, but so would commercial interests. Think of powering your laptop or other gadgets and toys using your own body heat ... makes power trips to the local fast food trough almost excusable.
