Mystery (electronic?) spiral seen on paving slabs seen in Norway

ent

Something to do with their electrically-heated sidewalks?

Nah. Clearly the spirals are associated with UFOs. ;-)

Thre is a guy that uses piezo electric transducers or some such to light LEDs embedded into walking surfaces.

Maybe it is him.

Ancient Norse rune. However Futhark does not feature a spiral; nor does Ogham or any other Northern EuropeanI could think of; so maybe it's from some ancient lost civilisation. Were there any road signs to Atlantis around?

The paving slab could have been cut out of a block to show a cross section through a fossilised marine invertebrate.

That is the antenna for one of their new, ultra high power mind control weapons. Now they will have to track you down and lock you up.

Could it be a car detector coil???

Funny, a pulse applied to the outer arms would make an excellent high voltage pulse once it reaches the inside of this spiral transmission line.

Just received an official answer from the Norwegian Tourist Office which reads:-

"The plates/spiral patterns in sidewalks who you ask, cover sensors for heating cables which is closed in the sidewalks. The sensors also detects humidity."

So now we all know. Thanks for all of the other interesting, and sometimes wacky, suggestions..,

The two separate connectors running closely parallel with a slight gap is a typical rain/wetness sensor.

About 43 years ago my Dad and my Mom took fine enameled copper wire recovered from an old transformer and stitched it into a rubber mat in similar parallel loops to detect a kid wetting the bed. A little sanding to remove enamel and expose copper and the ""moisture detector"" would trip a very sensitive relay.

A stripped out old radio case housed the relay and a door bell.

UNfortunately the sensitive relay also had a lot of impedence and created an inductive kick that gave the kid more motivation to not wet the bed than was originally intended.

It quickly brought an end to bed wetting.

I've heard of people using a similar "rain gauge" or "flood gauge" in their basement to alert to the early stages of basement flooding.

Somebody suggested that with dry salt placed on top of such a detector it might conduct well enough that a sensitive relay may not even be necessary.

Higher tech versions with electronics would of course not need such low tech tricks.

On a related note, they supposedly use a higher tech version of this to detect humidity for dehumidifiers etc.

As a Northerner with heavy Nordic ancestry and lots of snow shoveling experience I was ticked off when some electrically heated sidewalks in Minneapolis in the 1980's were outlawed and turned off to save energy.

The sheer labor, physical toll on people and massive business cost of snow shoveling made me somewhat UNIMPRESSED with the energy savings.

Heated sidewalks are particularly nice when it comes to freezing rain which is what we are getting here today.

Interestingly, here in Cedar Rapids Iowa, our halls of ""Justice"" needed some new sidewalk and I noticed that heating tubes/elements were built into the new concrete sidewalk/steps.

Apparently the ""energy savings"" trend has been reversed, and some penny pincher in government realized that the cost of snow removal was indeed large enough to justify heated concrete sidewalks/steps.

I suspect that heating concrete probably also can make the concrete last MUCH longer by eliminating the freeze/thaw cycle which is EXTREMELY destructive to concrete, tearing it apart from freezing in any hairline crack.

My own "hands on" experience has taught me that contrary to textbook science, an ambient of 32 F is NOT required for unheated concrete to melt ice/snow residue left after shoveling. In PRACTICE, Ice melts on my concrete driveway at 20 F withOUT salt or heating elements, apparently due to tiny amounts of solar heat BUT aided by some exposure of the darker wet concrete to sun light.

I would suspect that the detector you noticed in Norway was to detect snow cover.

They probably turn off a master switch for the few months of summer on the permafrost (sic).

Ya sure you betcha by golly!

Thanks for finding that out and posting it. I had a feeling I may be somewhere on the way to my grave and still not finding out about that since seeing the pictures. ;-)

Well, it's easy for them to say that, and such an explanation is likely to allay any disquiet in most.

But is it true? I mean, if you had a system for tracking the movements of every citizen in the country, would you admit it?

Actually, it looked like a teleport-node to me, but I can't see why they'd keep that quiet, so I guess it's not one.

They already do that by way of your cell phone/texting device.

Who are those "they" people?

Mine's almost never turned on. I doubt it can be tracked when it's off.

Every country has a "they". And it's evident that they have a lot of work, as evidence by the amount of stuff that people say "they" should do.

Sylvia.

Not the case with most folks.
