Wireless electricity!

I've seen a fluorescent lighting tube strike up and glow when brought underneath a high voltage power transmission line. With energy costs going up the way they are, we'll soon be begging the power companies to route new lines over our houses!

You're right. I don't know what my brain was doing yesterday - too near the power line perhaps!

It is likely that your stainless steel worktop was thin stainless sheet laid over a thicker steel substrate or at least some steel framing underneath.

I retract my retraction(!)

All of the stainless steel objects I use in my day job (high pressure fittings, pharmaceutical equipment) are all non-magnetic. Most are 316 or 316L SS.

In a strong enough field, materials such as aluminum become magnetic (e.g., within an MRI coil).

If the magnetic field is strong enough the whole body becomes magnetic. However, that is not due to the iron in the blood but the atomic structure of hydrogen.

Makes me think about the movie A.I., near the end, when the mechas "wirelessly resurrected" the boy robot. I suppose art imitates life. Or is it the other way around?

Is anyone else worried about the sort of tumours something like this is probably going to cause. All the various microwave rays and other things we've got shooting into skulls from our shiny new iPhones and such are bad enough, but actual electricity?

Call me backwards, but I find this stuff a little unsettling.
