Strengths: 1.  Perfect team work. Teams from mechanical design, teams from computer engineering, and people who've worked on massive motor systems, massive rocketships, and  aerospace, aerodynamic engineering coordinate pefectly. 2. Supporters and experimenters.   S everal commercial companies and dozens of student teams pursuing the development of Hyperloop technologies.  3. Good results. If it works out, this transportation can bring us great economic and time benefit. Risks: 1. Technology. The core technology of  this program still needs to be developed. 2. Economy and politics.
