I've been excited by the potential of hyperloop since the first time I heard about it maybe 30-40 years ago. The idea isn't new - there have been pneumatic trains in the 1800s and at least a design for a vacuum train in the early 1900s - it is the engineering challenges that have held it back. I'm sure these challenges would require no less effort to solve than projects like travelling to Mars, but the outcome would benefit more of mankind and would create something truly amazing (until it's been around for a while and then it would seem no more amazing than a laser printer).
