Well I am thinking one way valves along the tube set at one atmosphere. So if the train begins pushing air above one atmosphere, then the valves would maintain the pressure at the front and back of the train at one atmosphere. That is because the tube is a closed vacuum loop. At 600mph any...
yes I looked at maglev, but couldn't figure out which north and south poles were with which coils as only poles were noted in diagrams.
Do any actuators have a metal tube inside the coil?
Well a coil gun is partly right except that the projectile needs to be hollow to carry passengers and the metal gun barrel tube needs to be several hundred miles long and be evacuated so that we wouldn't be pushing a column of air through the barrel. The barrel would form a closed loop several...
I am interested to know if a copper coil wrapped around a iron pipe could be used to propel another iron pipe capped at both ends through the larger pipe with the copper coil around it?
I am thinking that the larger iron pipe would need to be slotted from end to end and insulated from the...
