Technocosmos
Technocosmos, later renamed Technostar, was an tall giant Ferris wheel that was built for the Expo '85 World Fair in Tsukuba, Ibaraki, Japan. It carried almost 3 million passengers during the exposition.
Technocosmos had an overall height of, a diameter of, and took 15 minutes to complete a revolution. Each of the 48 passenger cars could carry 8 people and was equipped with solar panels to power its air conditioning.
When it began operating, Technocosmos was the World's tallest extant Ferris wheel. At that time, the tallest Ferris wheel ever built was the Grande Roue de Paris which was demolished in 1920. In 1989 the Cosmo Clock 21 opened for business in Yokohama and succeeded both Technocosmos as tallest extant Ferris wheel and Grande Roue de Paris as tallest Ferris wheel ever built.
After Expo '85, Technocosmos was relocated to the Expoland amusement park in Suita, Osaka Prefecture, and renamed Technostar.
Expoland has since permanently closed. Work began on dismantling Technostar in November 2009, and it had been removed from the Osaka site by the end of the following month.Coordinates
