You can’t get much greener than a forest full of electrici-tree.

fixin’s, but for power. Because researchers from the University of Washington in 
Seattle have found there’s enough electricity flowing in trees to run an 
electronic circuit. <BR></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.scientificamerican.com/podcast/episode.cfm?id=tree-electricity-runs-nano-gadget-09-09-14">If you’ve ever made a potato battery, you know that plant material can generate 
current. But the energy in trees is something else entirely. The potato 
experiment uses electrodes of two different metals to set up a charge difference 
that gets local electrons flowing. <BR></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.scientificamerican.com/podcast/episode.cfm?id=tree-electricity-runs-nano-gadget-09-09-14">But in the current study, researchers use electrodes made of the same material. 
Sticking one electrode into a tree and another in the soil, they found that big 
leaf maples generate a steady voltage of up to a few hundred millivolts. That’s 
way less than the volt-and-a-half provided by a standard AA battery. So the 
scientists designed a gadget so small, with parts just 130 nanometers in size, 
that it can run on tree power alone. </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/F24B80E8-C516-4DD5-BCFF-11DB33CFA73B/blog/" title="blog or email this clip"><img src="http://content7.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>
