#19 of 25 EMF in hybrids by andyxandies Feb 21, 2008 (5:55 am)
Please see this thread below - the article in the comment section at the end (not the somewhat useless piece in the beginning) was from a reputable medical journal. This is posted strictly as a public service (the author's permission was not explicitly sought, but many blogs post articles that are useful this way ...) I believe that as many people as possible should be informed of this.   http://www.hybridcars.com/safety/electromagnetic-fields-in-hybrids.html   RKS6, you had mentioned that you were going to ask Toyota again about their hybrids to Scandinavia being EMF-shielded. Can you please tell us if they responded to you or they are still stalling? I so would like to get a hybrid - but this vexing issue is keeping me from it.

Here is the proper medline link for the article:   http://www.ncbi.nlm.nih.gov/pubmed/17572456?ordinalpos=1&itool=EntrezSystem2.PEn- trez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVLinkOut

Replying to: jhow (Feb 20, 2008 10:14 am) rks6,   Yesterday a message appeared from you about a colleague looking for information for a magazine article. When I came back to the forum today that post and a subsequent related post seemed to have disappeared. What happened? Did you do you pull the posts down; was it the Forum moderator?   jhow

jhow,   Edmunds pulled down the post. I don't see any mechanism on this site for corresponding directly with participants if they so choose. If there is a method I'm not aware of let me know.   I will re-phrase my information.   Jim Motavalli is currently researching EMF in hybrid vehicles. If you would like to share your experiences google search Jim Motavalli on your own.   Regards,
#23 of 25 Please read.. This seems like a definitive answer by mevander1 Jun 08, 2008 (3:14 am)
From another poster """As far as the electric motor, it is in front of the engine and under the hood. This is what's known as a Farraday shield. Why a car is the safest place in lightning is because it is steel and is a Farraday shield.  As far as the cables from the batteries under the rear seat to the electric motor, the cables are conducting current to and from the motor.. It is an electric circuit. The current is flowing from the positive battery terminal and returning to the negative terminal. That means that EMF induced by the positive is cancelled by the EMF induced by the negative currents. The EMF's are self cancelling Most measurements will measure the earth's magnetic field. which varies from 300 to 600 milli- Gauss. EMF's are not detectable by smell. The Plasmacluster filter has 3 levels of filters which filter successively smaller particles. It is called a micron filter. The last stage adds negative ions to counteract the accumulating positive ions. I looked in the fuses in the owners manual. There is not a specific fuse for the filter or it would be simple to disable  I look at positive ions as havining on OH ion Strong bases have positive ions  A negative ion could be viewed as having a H ion. Strong acids have Hydrogen ions If you look at the reaction between an OH and H you get HOH or H2O.  I find it difficult to explain the symptoms you are experiencing. They come and go in severity, so it is hard to pinpoint. I have not had my heater blow any air while off. I have it set on auto with my temp set at 68. My wife has her side set at 72. Nothing happens when heat is called for until the engine has warmed up enough for heat. So even when my heater is "on"" it may delay blowing any air.     The plastic components emit gases as they age. It may be that is what you are smelling as a metallic taste. I have had vehicles that looked like someone had smoked cigarettes in them as dirty as the inside windows got from plastic out- gassing. Clean your inside windows and look at the paper towels and see if they don't show up as some what dirty from the plastic out gases that collect on them """ Replies to this message: yssab (May 23, 2009 10:15 pm)

On EMF dangers. I am not familiar with the wiring in modern hybrid cars but in order for the return line to cancel the field from the positive terminal they must be bond together as in residential wiring. If they are not then they are like high power transmission lines which can generate very high fields. Cars usually have the negative terminal tied to the car body, so no return lines and if this is the case then cancellation would NOT occur. Also the Faraday shield argument does not apply to magnetic fields, only electric fields, and it is the magnetic fields that are of a concern. Finally, the earth's magnetic field is static and any reasonable measurement approach would only record dynamic or time varying fields, which are the health concern. I see nothing in these arguments, from an engineering view, that would make me feel good about buying a hybrid, unless I had time varying magnetic field data. If I have misinterpreted your response, please let me know. Thanks.

Replying to: mevander1 (Jun 08, 2008 3:14 am) I will refer to your first reply for the engineering of it all but I can say practically that there are varying levels of emf measurable easily and reliably with a tri-field meter (I have the emdex snap) in any hybrid. People who are sensitive report difficulties with readings over 1mg and those of us who have concerns about emfs are drawing the safety line around 2mg. I must give compliments to toyota for having taken obvious care to minimize the emf in the Prius (haven't driven other toyota hybrids). It is consistently under 2mg around all organs one might care about (torso and head) there is 3-4 mg reading around the feet but . . . I am not so worried about my toes. I tested the Insight and found readings from 2.5 to 4.5/5 - tending to be higher in the back seat, where children - who are always more vulnerable to environmental toxins - would be sitting. Readings at the floor were 14-20. In a standard (gas engine) car we have never found any such readings (.4 to .8 - perhaps getting up to 1 or so right on top of the instrument panels on the dash). The mere fact that Toyota has taken pains to isolate the electrical system I think speaks clearly to their assessment of risk and I applaud them for taking safety measures (even if ultimately for their own good) quite a few years before this issue will become one of common public concern.
