> Russia Yes, 630+ km Hyperloop between Moscow and Saint-Petersburg would be a great project. Problems: 1. Winter. Would solar panels give enough energy during winter? 2. Highly-inflated cost due to corruption. I would speculate corruption is a big problem for California HSR too, given its cost. 3. "Russian Railways" company monopoly for all intercity railways in the country.
