I think it is something to look into - We may be able to do alot with it.

Nice try, scientists. You'll never make the hippies happy!! lol. It's true, it's always something.
Posted By Joe - Thu, Sep 17 2009 at 11:18 PM ESTHaha.. Electrolites..
Reminds me of idiocracy, where when asked why people are watering their fields with Gatorade they replied "It has electrolites!".
Posted By Cheeto the Lion - Sun, Sep 13 2009 at 8:04 PM ESTRead this as : Current Bush
Yea, as a boy scout we learned all about the Current bush we could plug into for emergency power. Right up there with Snipe hunting and Submarine watching.
Posted By Anonymous - Sun, Sep 13 2009 at 8:02 PM ESTOK?
Ever heard of Nikola Tesla? All living things, including us, have electrical pulses that run through them. The earth has all we need. So, why is it the 'researchers' are just now getting around to 'discovering' this?
Posted By Anonymous - Fri, Sep 11 2009 at 11:00 PM ESTHow about this...
let science explore for the sake of pure knowledge. Who knows where it will lead. We cannot speculate of the outcome because we risk sounding dumb like the guy that said that there is a worldwide need for perhaps two or three personal computers. You all know who he was.

I've made batteries out of coins: take a nickel, place a small piece of paper towel on it, a drop of salt water on the paper towel, then a penny (well, really any two different coins, but penny and nickel work well). Touch your voltmeter, one probe to nickel, one to penny, and viola -- you have electricity! Not only that, it is easy to stack for more voltage: nickel, saltwater, penny, nickel, saltwater, penny; repeat. Tree power isn't all that unexpected or impressive.

Posted By Isaac - Fri, Sep 11 2009 at 5:16 PM ESTWhat about the research possibilities?
If the equipment scientists use to monitor the forests never has to have its battery changed, they can study more remote wilderness for longer duration. Sounds like a viable option to me.
Posted By Anonymous - Fri, Sep 11 2009 at 2:18 PM ESTNot sure this is real 'power' from a tree...
Is this really 'electrical power' or is it a chemical reaction between the electrodes and the sap of the tree? If it is just a chemical reaction, it is only temporary and may poison the tree. If it is real 'power' what is the effect on the tree? I am sure it cannot provide power without damage to itself.
Posted By Cody - Fri, Sep 11 2009 at 12:11 PM ESTYeah...
To all those who post, naysayers and supporters alike, mostly the naysayers though. I have one word RESEARCH. If this really would cause damage to trees I am sure they would figure it out and thus probably not be used. And you say it is pointless and sounds like you think it will not lead to anything, how can you prove it? Can you really say with 100% certainty that we can not make anything of this. ........ If you really think that, get off the interwebs..... any chance of a renewable.... More

Perhaps this all boils down to someone needing to produce some kind of output information due to receiving Grant money from the Government.
As a professional in the "electrical and electronics" industry, I can tell you that this isn't even worth the time it took to read it. There are many ways to produce the same or better results without even involving a tree.
Posted By Zoob - Fri, Sep 11 2009 at 3:04 AM ESTFeasability, Scalability ???
Assuming 25 millivolts per tree, a typical 110v - 120v system would require you tap into nearly 500 trees. The article doesn't even mention the kind of amps you can get out of one of these circuits. If the amperage is really tiny, then even tapping into these 500 trees could give you essentially Zero Watts (also read as No Power). And don't even get me started on the impracticality of setting up or maintaining the infrastructure for this system. Just an FYI! Interesting - YES. Practical.... More
Posted By G.P.Vijaya kumar,Bangalore - Fri, Oct 23 2009 at 11:37 AM ESTpower from trees
we have tested in our polytechnic ,we get around 500millivolts from ashoka tree with dissimilar electrodes.voltage varies from tree to tree .
Posted By Anonymous - Fri, Sep 11 2009 at 3:20 AM ESTYep
Agreed.. Pretty impractical overall. Passively collecting plentiful energy from the sun (that would have been lost otherwise) using increasingly efficient technologies seems uhh.. way more straightforward than some nature-stealing/imbalancing scheme.
Posted By Anonynous - Fri, Sep 11 2009 at 2:52 AM ESTCool discovery, but...
You simply can't get more than you take from nature. The law of conservation of energy states that the total amount of energy in a closed system remains constant. Sap power from plants for example, and there will be some negative consequence to offset the effort. You cant just "plug into plants" and expect all other variables remain the same. You always 'lose' something...
Simply put, charge your iPod and kill a plant.. or fifty...
The article (sans the poorly informed last.... More
Posted By Anonymous - Fri, Sep 11 2009 at 2:02 AM ESTSimply not true
The electricity does NOT come from the tree - it comes from the metal in the electrodes. The metal oxidizes and in the process releases energy. The tree does nothing.
Posted By Anonymous - Fri, Sep 11 2009 at 1:49 AM ESTTo the ones who think this is a bad idea.
Consider this: The computer you use to type your narrow minded tree hugging ideas is being powered by some sort of fossil fuel or if you are lucky enough to be on some grid that makes up less than 1% of this nations power, well good for you. It still took a substantial amount of fossil fuel to create your PC and to build and maintain your alternative energy source. The way I figure it you are more a problem than i am. I am not in denial. The way I see it, any advancement towards.... More
Posted By Anonymous - Fri, Sep 11 2009 at 1:43 AM ESTUh.. EARTH BATTERY anyone?
This isn't revolutionary in the slightest. Put two pipes a meter or so apart, of differing electronegativity (say, copper and steel, look it up for better combos) and voltage will appear. Often in the range quoted, or higher. In fact, one doesn't have to put one end in a tree even. Maybe the amperage is a bit better when a tree is involved, who knows -- but it's probably bad for the tree in the long term if so.
Posted By Anonymous - Fri, Sep 11 2009 at 12:35 AM ESTMore is better
If we give the trees more electricity they should grow even better! Just look at all the big trees that lightning strikes have made. We must continue this faulty flow of logic...What a bunch of tree huging weirdos.
Posted By Anonymous - Fri, Sep 11 2009 at 1:58 AM ESTWOW that was stupid!
I think your comment is actually getting stupider as it sits here on my screen.
Posted By Anonymous - Fri, Sep 11 2009 at 2:00 AM ESTReply?
If you're going to put a reply button under a comment, then stick the comment at the top of the list, then it's not a reply now is it? Now you've got one comment that's off-topic and bitchy and another comment that makes no contextual sense, all because you put 'reply' where it should not have been.
Posted By mike - Fri, Sep 11 2009 at 12:31 AM ESTOr we could save the trees and burn coal
Here in Canada there are many trees... They are fairly tough to.. when the temperature even dips past -40, they somehow manage to bounce back next spring . I highly doubt that a small ***** in the in the side of a sizable trunk would have any ill effects (just ask Pamela Anderson). If we can harness this truly green energy, it would be great for all of us. Or we could shread the trees into pellets to make energy once all the coal is gone... just think of the power in a whole forest.
Posted By anonymous - Fri, Sep 11 2009 at 12:24 AM ESTWow
Of course electrolytes produce electricity, but this is in the soil. soil isn't electrolytic, is it? Anyway, this is really cool. Talk about green energy! Maybe this will encourage more parks and forests to be preserved, even if only to plug electrodes into them for power. And if the tree needs the power, why didn't it evolve some way to insulate that power from the ground? And there are bigger applications to this then charging a cell phone. If they can find a way to get a higher voltage, or.... More
Posted By John Woods - Fri, Sep 11 2009 at 12:10 AM ESTWow
Dude, now that is some seriously cool stuff!
Posted By Jeremy - Thu, Sep 10 2009 at 11:54 PM ESTUmm... bad idea
It's bad enough these days with people throwing trash all over - but we do NOT need people to start poking holes in our trees.
Posted By Axel in Montreal - Thu, Sep 10 2009 at 9:17 PM ESTHave you heard about electrolytes?
At least it is not the discovery, again, of perpetual motion. This phenomenon appears periodically with a kid getting a voltage out of a lemon or a potato. The simple explanation is IT'S A BATTERY! A one-cell battery connecting two dissimilar conductors across an electrolyte will do this all the time.

Posted By Jenny - Thu, Sep 10 2009 at 8:10 PM ESTElectrical device plugs directly into trees for power
Shouldn't we stop to consider the consequences of tapping this source of power? What if the tree needs that energy? Draining it might harm or kill the tree. Not only that, but isn't the whole point of going to parks and wilderness areas to get away from electronic devices? If you want to keep your cell phone plugged in, don't go camping!
Posted By Anonymous - Fri, Sep 11 2009 at 3:01 AM ESTRE: Electrical device plugs directly into trees for power
Agreed... And given that trees produce oxygen, what do we do if we kill off large tree populations by tapping them as a source of energy. Do we really have to continue sucking up resources from ecosystems around us?
