How Soon for the Hyperloop?

Currently testing theory....

I've said it before, the air bearings should work fine to lift a car, as far as holding a cushion at over 500 MPH, that needs to be worked out. holding a partial or full vacuum in a 500 mile long tube will require a huge amount of energy!

Would the air bearings need more air in a vacuum?

nope the vacuum is to reduce air resistance and drag, the air bearing holds the weight of the car 1/4 inch or so off the floor

Where comes the air for the bearing ? This air will reduce the vacuum in the tube and what happens if the air source stops ? How will the vehicle stopped ? Which deceleration?There are a lot of questions and for the time being no answer.

"holding a partial or full vacuum in a 500 mile long tube will require a huge amount of energy!"

No, pumping down the 380 mile tube from 100KPa to 100Pa takes a lot of energy, say 2 MW over 24 hours. But once there the only energy required is replacing leaks.

I hope this works. It would beat getting to the airport an hour early and taking your shoes off.

Wait......we will probably have to get to the station and TAKE OUR SHOES OFF!

Somebody needs to hire a specialist who can place decimal points at most one position away from the correct place.

Highly skilled job being a decimal point placer. Not many around in the market these days.
