It is really distressing that the CO2-cutting generator at 2005 World Exposition Aichi failed its objective of reducing CO2 emissions .
The group of team behind it had sought to invent new energy power generation system by combining solar power generators and fuel cells and had built a huge machine at the expo but only to be proven otherwise. While its energy source was as simple as food scraps collected from restaurants at expo venues and had provided 2.7 million kilowatt-hours of electricity during the expo it unfortunately produced 270 tons more CO2 than if the electricity had been generated using conventional methods.
