1967 Bay Area Gravity Vacuum Transit next to BART track ... sounds like Hyperloop https://en.wikipedia.org/wiki/Pneumatic_tube#In_public_transportation https://en.wikipedia.org/wiki/Pneumatic_tube#In_public_trans... Using the well known pneumatic vaccum tube not just for parcels but for public transport is not a new idea. There have been such transports for some time long in the past. The current question will the first such public transport in this century be built in US or in China or somewhere else. The Transrapid magnetic train was built in Shanghai China (called Maglev there) by Siemens from Germany, another such cool idea that has little usage - but it works like a charm there with 430km/h on a elevated 30km track for more than 10 years.
