Man walking in field left baffled by unusual 20ft object but there's explanation

A man was floored after stumbling upon a giant, unknown object laying in a field while out for a walk. The sighting occurred when the bloke was staying at a cabin on a getaway with a few friends and, after venturing out into the local area, they stumbled upon the 6 metre (almost 20ft) long entity between some of the cabins.

The item, a huge spiral shape, appears to be made of plastic or fibreglass and closely resembles a giant screw. It was found on the “south coast of Norway”, not too far away from the ocean. On a quest for answers and clarity surrounding the bizarre object and what it may be, the man took to social media to see if anyone could provide answers - and internet sleuths were able to determine what it actually is.

The curious man shared an image of the sighting on Reddit and explained: “Large yellow plastic/glass fibre spiral found on the south coast of Norway. It's about 1.5m in diameter and 6m long.”

In the comments section, he added further information: “Me and some friends found this while staying at a cabin and were discussing what it could be.

“I was thinking maybe an Archimedes screw, but the ones I’ve seen [have] a more flat/open design.

“The area we found it have some industry and stuff but that’s kinda far away and hard to get to. The exact spot we found it, it’s just in a field in between some cabins about 50m from the sea. And the coastline next to it is too rugged for a big boat.”

Other Reddit users were keen to share their theories. One person said: “A screw lift. Likely for heavy liquid or grains."

Someone else offered a different perspective and said: “It looks like intentional art to me. I put things in my flower gardens (smaller of course) like this as art.”

But it seems the man’s initial guess of an Archimedes screw was closer to the truth. One person said: “I think it is an Archimedes screw, also because of the connector flange. But maybe one to generate power instead of pumping. Therefore the steeper gradient.”

And another added: “It's an Archimedes screw. This one is from some Flumill tidal power project.”

An Archimedes’ screw - named after the Greek mathematician - is a reversible hydraulic machine which can be used as a pump as well as a generator. They’re typically used in wastewater treatment plants.

The Flumill organisation, which this particular Archimedes’ screw is believed to belong to, is on a mission to “become a well recognised player in the green transition through technology for extracting energy from the natural flow of water with low impact on the marine fauna”.

On its website, it states: “The Flumill technology is based on know-how from the Norwegian oil and gas industry.”
