An ***XMAS*** gift for me  

Hinged...
I beleive that the cylinder is removed for cleaning by loosening the set screw on the bottom and swinging the hinged handle apart.

I agree Olive...
The handle is obviously split and the the screw on the bottom can be tightened. It's again an indication that this has not been prototyped properly because if it was the prototype would confirm that the pressure at the bottom is higher than on the top of the cylinder, which would make it leak and probably crack when hot water is poured into it.
By the way Azure friend, male dogs make better tea!

interesting
a fascinating insight into 3d rendering Koen.
Could the sealing issue be resolved by the use of 45 degree chamfers on the glass and the casting. Obviously the casting would be machined for 'o' rings.
Having said this, I'm imagining that production costs might put this in the Porsche category.
Surely this design would not be realised in cast stainless steel ?

the designer of the teapot has a blog and a video of the design in use.
a scroll through his blog shows how he came up with the design and
the process. he also mentions receiving one from the manufacturer (asia),
oh my, and uses it to demonstrate in the video.
in my opinion, the video shows a less than sleek object compared to the
slick computer rendering. though could be a one off first run?
