Plant Physiology and Lightning
Friends,
In a moment, the results of my experiments - but first off, I think I might have been had (again - on the Chat Zone below). Correct me if I'm wrong. The fact is there are ideas scouts out there, and they can be cunning. Esteban Cabrera once wrote to me after one of my ideas was swiped, "Take care Mr. Scarborough, because 'the boys' are hungry for new things." An example. Someone posed on the Chat Zone as a humble experimenter wanting TENS circuits/ideas. It turned out he was the head of a company that manufactures the units in South Africa - but he had posed as someone else. He got all he needed before I discovered it. Another example. Someone contacted me, posing as an expert who wanted to discuss metal detecting principles. The next thing a design of mine (modified) appeared on a website. In that case the web page was removed on discovery. Regrettably I at first assumed the wrong culprit - I know the name now. Such people appeal to your sense of pride - go on, your stuff is pseudo-rubbish, your ideas won't withstand scrutiny. And such a person is likely to be untraceable, and their name might never appear again. Or conversely, they say I'm a leading expert, let me share the following information confidentially with you, and what can you share with me? Or they'll appeal to your sense of benevolence, and so on. However, I should add that most people don't have such deceit in them - the problem comes in distinguishing those who do from those who don't, which I haven't been terribly good at. With this in mind, I believe that I have said too much with regard to my plant physiology experiments (on the Chat Zone below), and therefore I have decided to reveal what I have been experimenting with. Perhaps someone else might like to run with these ideas. I developed a circuit that triggered on a tree's physiological response to static charge - and judging by my results, this ought to include lightning. The circuit worked, but it was unstable, and I don't anticipate having the time to smooth out the problems to take it to a publishable standard (I'm embarking on a Master's degree this coming month and need to "clear the decks"). Well I happened to be experimenting simultaneously with atmospheric charge and plant physiology - the first of these being the basis for an EPE project which the editor has hinted at - the second being a science project that I was helping some students with. What would happen, I wondered, if a tree were presented with a static charge? I experimented with ash trees, as well as smaller plants, and the results were striking. When I touched the trees with a charged item, they instantly pumped themselves up to (I assumed) a high potential, which they held steadily for a few minutes. The trees further showed a reaction when only the air surrounding them was charged. But I had a problem, which I have roughly described below. Any given section of a tree gave the same voltage reading, but concatenated sections gave readings that didn't seem to make sense. How high really did the potential rise across the whole tree, top to bottom? By extrapolation, perhaps hundreds of volts. But it's an open question. I thought, what is the meaning of this? My reasoning as follows: Any tree which were "pumped up" like this might lessen its "visibility" beneath a thundercloud. That is, it would reduce the likelihood of a lightning strike on the tree, since the tree would be more negatively charged in relation to the cloud. This would seem to agree with studies (reported e.g. in New Scientist) which show that the occurrence of lightning is reduced over forested areas - studies which have so far expressed a greater or lesser degree of bafflement over the phenomenon. A more distant thought is - if this should be true, that trees protect themselves from lightning by "pumping themselves up" electrically, then how much electrical energy would a forest contain during a thunderstorm? Enough to be tapped? As a further development of this idea, it would seem that it might be possible to charge up the human body to become "invisible" to a thundercloud, perhaps with a small hand-held device. The recruitment of volunteers for the first field tests will commence shortly. Thomas Scarborough, 23 August 2004, on the EPE Chat Zone www.epemag.wimborne.co.uk |
