How does ET3 utilize the vacuum? How do you make it work?

ET3 uses standard off-the-shelf vacuum pumps to permanently remove air from the tubes.  Most of the time the pumps will be turned off, unless to run for a while to remove any air that leaks in.  Pumps running too often indicate that a leak needs to be repaired.  Leak repair can occur from outside the tube without shutting down the system.  NOTE: ET3 is NOT like pneumatic tube systems that rely on air movement and pressure differences to propel the capsules, the capsules are magnetically levitated, and propelled by linear electric motors.
