To ask the question, what kind of things do we research which are absurdly stupid? In this case clearly the guy hasn't asked a pilot or an engineer for their thoughts.

How do you land on one??
With difficulty. But they simulated that as well. Lots of documentation here:Originally Posted by CAT-THE-FIFTH

But they've completely ignored emergency procedures, if you've got an engine out the last thing you want to do is be landing on a curve making the rudder control even harder. Not to mention the gradient being very difficult and making the landing gears job harder, before we even consider the increased issue of a wing strike (ie starboard wing on a clockwise path) which is before we go on to increased loading and spin stalls.

As mentioned, they simulated most of that - certainly wing strikes, landing gear loading etc. The forces experienced by passengers is higher, but still in the comfortable zone.
Rudder control on a straight runway in a crosswind is likewise hard if you've got problems, but this design greatly reduces the impact of crosswinds and replaces it with a fixed radius curve.
What's stupid about this? A lot of research gets reported by the media as stating the bleeding obvious, but sometimes it questions what seems obvious - and that's one of the jobs of science research, to find out what we take for granted that is and isn't valid. Some of it is spurious, like mathematicians being paid to work out the optimal monopoly strategy, or what speed to walk with a cup of tea to stop it overflowing - but that's just the stuff that sticks out, and it's not quite a lock that even spurious research can provide otherwise useful results.
Next I want to see a circular aircraft carrier
Terrible shape to cut through the water but it got me thinking about whether you could have a rotating ship/ekranoplan/flying saucer that uses ground effect to stay just above the surface.Next I want to see a circular aircraft carrier
More importantly, the rotating runway could act in a similar way to a treadmill and would enable pointless arguments about whether or not a plane would be able to take off from it.

This sounds like an idea you would research for maybe one evening; in a pub!
Thinking about the treadmill problem, one answer could be giant fans! Create a consistent 170mph wind and then aircraft can "hover" and land on a much smaller runway!
They are already using giant fans in many parts of the US to increase the speed of the earth's rotation. This is why the days are shorter now. It's about stopping global warming.This sounds like an idea you would research for maybe one evening; in a pub!

Maybe put the giant fan on the aircraft so it can lift itself?
Why not have a spiralled runway going into the earth?
As I said thou, imagine emergency procedures due to engine out. It would be very poor.
They didn't model (that I saw) the issues of additional drag and stall.
But mostly, cross wind landings are hard often because of gusts of wind. If it's constant enough wind and within limits it's really easy. If it's gusting then, well, then it's more challenging. The highest cross wind landing I've ever made was a greaser because the wind was suddenly constant and tower kindly gave me running wind speeds during my approach. I would hate to do this on a curve it's hard enough in a straight line.

Ditto to all the derision and scorn being poured on this idea. I am highly cynical towards this.
And to answer the title question - I'm afraid I'd have to look into that some more: gather balanced and controlled information together, then review it dispasionately with analysis and interogation. Only then could I draw sufficient conclusions to provide a meaningful response. I shall call this process...
.... research.
Shall we set up a committee to review whether we need a committee to research whether any research is needed?
The guy who dreamt the idea mentioned the word centrifugal forces. Surely this is a basic error in Physics as there is no such thing.
*ahem*
