Place London Eye
The London Eye architects David Marks planned and Julia Barafild. Roll 32 cells enclosed, air-conditioned passenger, or "bubbles"; Every bubble place twenty-five passengers, so all in all 800 passengers can travel wheel at the same time. The wheel rotates at a speed of 0.9 miles per hour or so, the passenger cell surrounds the wheel every half hour or so.
The wheel does not stop the rotation to pick up passengers. Speed slow enough so that passengers will be able to enter and exit the cell while the wheel movement.
