Expo 2005 Aichi was an epoch-making World Expo in every aspect, as it sought innovative solutions for various issues in society, in line with the aims of Expos and the BIE. Through innovative exhibits, events, and operation methodologies, the event - themed "Nature's Wisdom" - expressed and demonstrated all the possibilities and potential embraced through technologies, social transformation and people’s behavioural changes driven by enhanced awareness.
World Expo 2005 Aichi, which opened its gates 15 years ago today, was the venue for numerous technological innovations, including the Super Hi-Vision Theater - where the public was introduced to what is commonly known as Ultra HDTV for the first time.
Fuel cells, a promising and virtually limitless energy source that can be used for various applications including transportation, portable appliances and stationary installations, were first discovered in 1839 by Sir William Grove. However, it is only in the past two decades that the technology has become a viable and practical solution. With water as its only by-product, fuel cell technology is in line to become one of the key next-generation solutions for Future Energy.
This forward-looking and eco-friendly technology, which involves an electrochemical process where hydrogen and oxygen are converted into water to produce electricity, was showcased at Expo 2005 Aichi in Japan via a fleet of specially designed buses.
