An engineering company claimed it could produce electricity simply by wiring a nail in the tree’s trunk to a metal rod in the ground. Sure enough, the demo worked—but nobody knew exactly why.</blockquote><div style="border-bottom: solid 1px #dcdcdc; white-space: nowrap; margin-bottom: 8px; background-color: #eeeeee ;background-image: url(http://clipmarks.com/images/source-bg.gif); background-repeat: repeat-x; height: 24px; line-height: 24px; vertical-align: middle; padding-bottom: 4px; color: #666666; font-size: 10px;" ><a href="http://clipmarks.com/clip-to-blog/" title="see clips that are hot right now"><img src="http://content6.clipmarks.com/images/clip-icon.gif" alt="" width="19" height="19" border="0" style="vertical-align: middle; margin: 0px 4px; display: inline; border: none; float:none;" /></a>clipped from <a title="http://www.conservationmagazine.org/wp/wp-content/uploads/tree-light.jpg" href="http://www.conservationmagazine.org/wp/wp-content/uploads/tree-light.jpg" style="font-size: 11px;">www.conservationmagazine.org</a></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.conservationmagazine.org/wp/wp-content/uploads/tree-light.jpg"><IMG src="http://www.conservationmagazine.org/wp/wp-content/uploads/tree-light.jpg" alt="http://www.conservationmagazine.org/wp/wp-content/uploads/tree-light.jpg" /></blockquote><div style="border-bottom: solid 1px #dcdcdc; white-space: nowrap; margin-bottom: 8px; background-color: #eeeeee ;background-image: url(http://clipmarks.com/images/source-bg.gif); background-repeat: repeat-x; height: 24px; line-height: 24px; vertical-align: middle; padding-bottom: 4px; color: #666666; font-size: 10px;" ><a href="http://clipmarks.com/clip-to-blog/" title="see clips that are hot right now"><img src="http://content7.clipmarks.com/images/clip-icon.gif" alt="" width="19" height="19" border="0" style="vertical-align: middle; margin: 0px 4px; display: inline; border: none; float:none;" /></a>clipped from <a title="http://www.humacon.org/2009/08/26/a-way-to-harvest-electricity-from-trees/" href="http://www.humacon.org/2009/08/26/a-way-to-harvest-electricity-from-trees/" style="font-size: 11px;">www.humacon.org</a></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.humacon.org/2009/08/26/a-way-to-harvest-electricity-from-trees/">Using a device that extends probes underground, Voltree’s invention harvests the energy and uses it to continuously recharge a battery, which in turn powers radio-equipped sensors. Voltree is now working to assemble a wildfire alert network that can feed sensor data to a central location. The devices could also monitor climate conditions or even detect illegal radioactive materials at the border.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.humacon.org/2009/08/26/a-way-to-harvest-electricity-from-trees/">tree-powered sensors could be deployed over vast areas with little maintenance. And not to worry, Mershin says: the amount of energy harvested is so tiny that the trees won’t feel a thing.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/71CDCCAB-2AB7-407C-A1C2-A5671F7F50F8/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
