Spluch coughs up the details on this artist's conception of a project to be completed next year in Tianjin, China.
It'll be 110 metres high, holding 48 sealed air-conditioned capsules, which in turn hold as many as 8 passengers. It'll take a half-hour to completely spin, so this truly is an observation platform and not a ride.
The river it's crossing is the Haihe. I'll bet it's part of the program to build things for when they host the Olympics.
