Power lines and props

There is a story about power lines possibly being a cause of energy for the sudden acceleration of Toyotas.· I've heard if you take a florescent light around powerlines, they will light up.

I'm just curious what effects a field of energy would have on the prop or other electrical components.· Has there been any studies?

    Not sure if any studies have been done but I carried one 8 foot and one 4 foot fluorescent tube under a 660KV transmission line to settle an argument one night. Neither one lit up. However both will light up if you get close enough to a high power RF transmitter. Best if you are NOT holding them at that point.

    I've placed both a BS2 and a propeller under some powerlines just up the road from the house and did not notice any sudden acceleration, sorry.

    There is all sorts of stuff on this. This will get you started...

    I tried this once and got some glimmers of light. Nothing spectacular but those particular power lines crackled and hissed a lot all the time so it didn't surprise me that the fields might be fluctuating.

    Somebody told me the Mythbusters tried to get power off a power line by placing a coil nearby but they got nothing to speak of. I've always wondered if the Mythbusters rectified their output or were just looking at raw voltage, which I presume would read zero if they were using a regular voltmeter. nono.gif

    Metal objects under these lines can shock you.
