Is Tree Power in Our Future?

Posted May 22, 2010 7:53 AM

Researchers at MIT and the University of Washington discovered that they can stick electrodes in trees and operate electrical devices, such as a low-powered sensor. The power isn't much—only 200 mV per tree. Some skeptics think it's no more than the old potato trick, where electrodes react with the potato to create a potential difference. What do you think? Can we eventually extract usable power from trees?

We have been extracting useful power from trees for thousands of years by burning them. If it is a plant based electrochemical cell that you desire a lemon is far more portable than a tree.

Silly silly silly, leave the trees alone, I need 'em to make bows, and I don't want holes in 'em all.
And like Ace says...been there...done that.
Man, the more I think the more stupid it sounds...
D'uh we get Maple syrup from trees, that has a high energy content.
People have messed with tying hydraulic pumps to the tops to harness the wind.
Just plant e'm and leave 'em alone...let them do that funky thing they do so well, which is enrich the soil, promote biodiversity, help stabilise the environment, control run off, shelter us from the wind, provide fuel..
Jeez you'll be wanting trees to come and wipe your ar$e next...Oh, they already make the paper to do that.
I think over the millenia we have pretty much got trees sussed...we are jut too thick to realise we should be planting a lot more.
Some of my best friends are trees (or at least live in them...now where is that pesky squirrel?)

This is a typical "gee whiz" "scientific" notion that has all the decimal points about four places off. But since when do reporters know how to do arithmetic? Or when or why or just what arithmetic...?

I dunno, it all sounds barking (OK, self-slapping for bad pun is in progress).

These potentials were investigated as evidence of electrical fields as organizing growth by Harold Saxton Burr in the 1930's. Much is to be found in the Yale Journal Of Biology And Medicine . There is also current interest in the slow fluctuations of standing potentials on the human body as state indicating variables. Ovulation shows in potential difference between forefingers. As for power from this source, not so much.

Just in case there is something useful here, I think we should implement a policy of reforesting all of North America, Northern Europe and East Asia. Even if this turns out to be bogus, we still win, because a world full of trees is prettier than a world of concrete...

Wait a minute. That's my recommended solution for Climate Change. Never mind. Any excuse for planting trees is a good excuse....

Some of the 'green' bloggers troll the MİT web site looking for wonderful new things that they have no idea what they are to post and be cool. MİT noticed this and now seem to post every thing they can think of as it gets their name ever more recognized and the guy with the MİT site seems to like the notice. Most of the posts are about basic research and will never see the light of day (outside the lab). The one in a thousand that may be of some use is probably 20 years or more from really coming to public notice. The tree thing falls into the really basic group - say 3rd grade.

That is perfectly stated. The problem is not just with MIT (I'm trying to be balanced here). There may. or may not be, credibility to some of this stuff, but I am sick to the back teeth of this 'researchers found...' crap.

A great deal of PhD level research is very valuable, but an awesome amount is not. The UK has progressed from 'we want everyone to do post 16 education', to 'all must do whatever exams to 18 yo', to 'all must have a degree'. It's become such an absurdity that now, all must progress to PhD. WTF ? We seem to have lost all concept of what is a uselessly to learn and a valuable job.

Result of said situation is youngsters doing mickey-mouse degrees, degradations of standards, and employers not having a clue what somebody's abilities are. I don't know how it is outside the UK, but some snobbish type style culture has undermined the value of young people progressing thru life via the more traditional apprentice type route. Fair enough that some to go the academic route and expand their ability, but for the majority, progression is via workplace experience. Each has value. The UK is obsessed with all youngsters having a degree, and this helps nobody. Skills are acquired at any level - the person who left education at 16 and learned 'on the job', or the person who went thru the mill and can provide more tech type expert knowledge.

Sorry for ther ramble, but this one makes my blood boil. We have forgotten the value of learning on the job, and we have also undermined any meaning attached to higher levels of study. "We" ? I've never supported such, but unless we collectively shout it wll not change. It's no wonder that employers have to resort to in-house tests to evaluator job applicants. All that may only make sense to Brits - I hope to crap it's not as bad in the USA. The UK has lost all respect for peoples ability in it's politically driven rush for academic standards. I could rant like crazy on this topic, but it's somewhat beyond the topic. Where, in the name of ********, did we lose the ability to value peoples skill at all levels. A young person who learns a trade 'on the job' is every much of value as one with paper & certs. Matching people to skills is the key, and employers are no longer see the difference. The bloke who delivers my mail ( and yes, I've done that), is every bit as valued as the geezer who came to lop down a tree/service boiler, and the structural engineer who gave me a report.

Now get on your bended knees and praise the fact that I feel the need for coffee. It will spare you more waffle . (hey, don't blame me, it must be the yoga blog).

Yah,I was feeling normal when I started reading this blog. Ah well, you have at least given me food for thought. Sunday is a good one for cogitating such stuff.

You can find those trends of which you decry are very prevalent in the US as well...Actually, I do believe the source of the trend can be traced to the 1944 signing of the GI Bill by President Roosevelt...

One does not level a sandpile by elevating the lower grains, and making a college education available to all comers can only end up lowering the standards and thus reducing any perceived value.

Manual labor, i.e., that work which actually results in the creation of value, has always been low on the status tree, becasue everyone else lives off "adding value" up stream. Allowing this to spoil one's morning coffee is going to have about as much effect on the situation as, say, Barack Obama pretending to contribute to the Gulf blowout crisis by "keeping his bootheel on the throat of BP"...

Poor old Barry Obama thinks he has to do and say something for political reasons but unfortunately being a community organizer doesn't provide much background for anything but whining.

Kris. Please stop banging on about the UK pushing useless degrees etc. Even if it does make your blood boil. I happen to be a Brit working as an Engineer in the USA. I know both perspectives. I have interviewed approx 50 Americans for jobs while over here, and I think our 2 countries are more alike than dis-alike.

In the UK we also put potential hires through psychometric testing, skills testing etc. We don't just demand degrees. In the US I look for skills before qualifications. Unfortunately the attributes that you miss when you hire based on skills alone are usually the basic academic ones, such as lack of being able to put a technical report together, spelling, computer skills etc. A degreed (or O level, ONC / HNC type person) will have these skills, as well as the experience to carry the job.

I don't see it as blood boiling stuff, and you make some very sweeping generalized statements, which I personally would hold back from, I think you may be leaning towards mis-leading a lot of people about the UK. Read your blog a few times, it makes less and less sense. " I could rant like crazy on this topic". I think you already have.

Not all jobs on this planet require the ability to put together a technical report, spell, or use a computer. Such jobs are every bit as valuable as those requiring more extensive academic knowledge, they simply don't require 3 + years of tertiary academic training. A newly qualified graduate will not have the job experience as somebody who'd been in the workplace since 16/18.

That is true but the ratio is like a million to one! The bloggers don't care as they will get paid by the hit anyway.

Hey all together!

It seems to me, that there is hidden a fundamental error still in the question.

mV or V is not a power, but a electrical potential difference between to points. If you want to know the force, you will have to put a resistance between those two points and measure A(mps) and then after a second you may talk about power!

Is there no idea about electricity and teir laws?

An infamous prize should be in play between the OP for his double mistake (if you mistake one thing, you're wrong twice), and the reputed MIT for such a (I don't even know how to call it) !. I'd be more interested on the results if they had used their butt-cheeks instead of trees!

Disappointing !!

Yes, that works good. I am training 2 flies to pull my wheel barrow. Only 60 trees to charge my car battery, and probably just only 350 years?

As far as I know this invention of electrical potential is an old one (I personally have read it in my younger age in Science or some other journal) and I am not talking about the signals of JC Bose. It is this specific one, only the milli or microwatts available was not found to be lucrative.

I have a better suggestion to the MITs - what about tapping this same electrical signals from the heads of homo sapiens? after all already (or in near future) there are likely to be more of them than trees. And another likely high density electrical area is the heart.
