 (A) Do you have a smart speaker at home? No, but I have an iphone8! It is a smart speaker too. (B) What is a smart speaker?  These smart speakers enable us to do a variety of different things from controlling wireless-enabled lights to ordering various products and takeaways online as well as providing information like the weather forecast, time, date, and many more things. And they can also stream music to the speakers themselves. In fact they are what is termed, virtual assistants. (C) How does a smart speaker work? The key to the operation of smart speakers is the voice recognition technology that is used. Using voice recognition, it is possible for the smart speaker to understand what is being said and act upon it.

  Hyperloop sysyem! It's speed is faster than the high-speed rail, which brings cities close together.How fast ? For example That's quick enough to go from London to Edinburgh in 45 minutes. Strengths: 1. No or little friction or wear problems. 2. It can rotate at super high speed. 3. There is very little vibration and noise. 4. It can be used in special environments without lubricating oil.  Risks: 1. E xpe nsive. 2. When the power is cut off, there is a need for countermeasures for the failure of the control unit. Therefore, the super-loop train will indeed change our lives! Not only improve the quality of life, but also bring convenience!If Taiwan develops a super-loop train in the future, I will definitely want to experience it!
