Tree power
« on: July 11, 2009, 09:09:43 PM »
I recall a few years ago, a company called MagCap found you could pound a nail into the ground and another into a tree and get a small amount of power from the wire. A few of us tried it out and saw it worked. Well, it's gone commercial through a company called Voltree Power. It turns out the source of the potential difference is the higher acidity of the ground. The amount of power is miniscule though.

And there's a good diagram on:

PS. I searched but couldn't find where this was discussed before. Sorry if there's an old topic elsewhere.

@Steven Dufresne

At the time I had interviewed Gordon Wadle who had a patent on a magnetic shield and I had then learned that he was part owner of that tree power company.

The report of that interview is here;
http://www.overunity.com/index.php?topic=6207.msg143204#msg143204

The most interesting thing he said regarding the tree circuit was that the earth ground is positive. He said this in such a confirming manner that it just did not click at the time. I never knew the ground was positive. This could be a subject for debate since we spend most of our time grounding the negative. Hmmmmm. Probably falls in perfectly with the notion that the north pole has a south polarity.

It could be that the acidic ground was positive relative to the interior of the tree where they pierce it to. The ground could still be largely negative relative to the air above the ground. Just guessing.

Found on Gizmag today: http://www.gizmag.com/tree-powered-electricity/12772/

Researchers at the University of Washington (UW) have taken the term ‘green power’ literally by running an electric circuit from the power generated by trees. Sure, there isn’t much electrical power to harness, but the researchers say it should be enough to run wireless sensors that could be used to detect environmental conditions or forest fires and could also be used to gauge a tree’s health.

The UW team’s research follows on from a Massachusetts Institute of Technology (MIT) study last year that found plants generate a voltage of up to 200 millivolts (thousands of a volt) when one electrode is placed in a plant and the other in the surrounding soil. Those MIT researchers have since started a company developing forest sensors that exploit this new power source, but the UW team sought to further academic research in the field by building circuits to run off that energy. They successfully ran a circuit solely off tree power for the first time recently.

By hooking nails to trees and connecting a voltmeter, UW undergraduate student Carlton Himes found that big leaf maples generate a steady voltage of up to a few hundred millivolts. The team then developed a boost converter that takes a low incoming voltage and stores it to produce a greater output. The custom boost converter works for input voltages of as little as 20 millivolts and produces an output voltage of 1.1 volts, enough to run low-power sensors.

The circuit the UW team developed is built from parts measuring 130 nanometers and consumes on average just 10 nanowatts of power during operation. Normal electronics obviously aren’t going to run on these types of voltages and currents, so there’s no use packing that big screen TV for your next camping trip, but as new generations of technology come online they will continue to re-evaluate what is doable and not doable in terms of a tree power source.

Despite using special low-power devices, the boost converter and other electronics would spend most of their time in sleep mode in order to conserve energy. This created a complication because if everything were to go to sleep, the system would never wake up. To solve this problem, the team built a clock that runs continuously on 1 nanowatt, about a thousandth the power required to run a wristwatch, and when turned on operates at 350 millivolts, about a quarter the voltage in an AA battery. The low-power clock produces an electrical pulse once every few seconds, allowing a periodic wake-up of the system.

The researchers point out that the tree-power phenomenon is different from the popular high-school potato or lemon experiment, in which two different metals react with the food to create an electric potential difference that causes a current to flow. So, in order to distance the tree-power effect from the potato effect, they used the same metal for both electrodes.

The researchers say it hasn’t been established exactly where these voltages come from, but there seems to be some signaling in trees similar to what happens in the human body, but with lower speed. In this way they are hoping to apply the their results as a way of investigating what the tree is doing, much like measuring a pulse in a human.

The UW team’s findings appear in a study to be published in the journal, Institute of Electrical and Electronics Engineers' Transactions on Nanotechnology.

Someone mentioned earth as positive. I found out by playing with coins, and salt paper between them, checking the polarity. It changes when different coins are used. I tried this with pieces of metal, screws and so on. It seems the polarity is not about the salt water paper used in between but in the metals used. So doing the same with earth batteries, just two pipes of different metals in the earth, we can get positive or negative depending on which metals are used. It really has nothing to do with the earth or its acidity, all tho Im sure this could affect the energy produced. But its all about the metals, relative to each other as electrodes.

I think what people mean when they say this is that the earth is positive with respect to the ionosphere - I know that's what I mean when I say it. Polarity/voltage is all relative, so to be clear you always what to say what it is relative too.

from :
http://www.ce-mag.com/archive/02/07/mrstatic.html

"If a properly grounded fieldmeter is brought outside and directed upward, the meter would likely measure an electric field directed downward with a strength of approximately 150 V·m–1. If the measurement were made on a mountaintop, the field may be 10 or more times stronger. These measurements are indicative of fair-weather conditions. "

a 1.75m tall man has between his head and feet a voltage difference of 265 volts

a a tree 15 m high 2250 volts

this is also the source of our life?

(helix DNA .... earth voltage gradient + earth magnetic field = magnetron)
You can see why it is dangerous to stand under power lines
