In Japan, the Osaka world expo has been held since April 13th, but it will be over on October 13th. It means today! I have seen many the expo-related news online and on TV. Some of my coworkers and friends visited there and really enjoyed many different pavilions and so on. Unfortunately, I didn't go to the expo because I couldn't seem to draw a raffle ticket. According to the online article I was interested in, they showcased cutting-edge technologies which can change the future. Some people might have already known, but let me share some of the interesting technologies here. 1) Flying cars. They are a vertical take-off and landing aircrafts which can bring people and things by electric power. The developers aim to make them easier to use like cars and hope they will become things in close contact with people's life. 2) Electric vehicle buses. They can charge by wireless power transfer technology(WPT) while running. They are also auto-driving buses with Level-4. The developers aim to reduce an environmental impact and believe that it will be a future public transportation. 3) A hydrogen-fueled ship. It can move by electric power generated by hydrogen and oxygen and is eco-friendly because of CO2 zero emission. Compared to conventional ships, there are no noise, vibration or smells of fuel. I believe that it won't take much time to commercialize those state-of-the-art technologies and I expect I will experience them in the future.
