The Las Vegas Strip is buzzing with construction on the High Roller wheel, which will set a new height record in late 2013. That is, until New York or Dubai catch up: both have unveiled plans for flashy waterfront Ferris wheels. They’re betting on the kind of success seen in Singapore and in London, where 3.5 million people line up annually for their turns on the London Eye. Some of these cool recent versions put a high-tech spin on the Ferris wheel concept. Santa Monica’s Pacific Wheel, for instance, uses a solar-powered design and glows in neon by night, while Tokyo’s Big O Wheel is an engineering marvel that operates without a center axel. Instead, a roller coaster zooms through the wheel’s hollow center."
