It doesn ' t take any energy to hold a vacuum , so long as the seal is perfect . Even with a perfect seal as soon as power is cut air will flow back through the fan and release whatever is being held which is likely what you ' re seeing in the mythbusters video when power is cut . If the seal had no leaks and they added a valve to the hose which was shut off before the motor was cut the car would remain suspended . So yeah , once the vacuum has stabilised all the motor is doing is preventing air from going the other way back down the tube and so will be drawing much less current then when air was actually being pulled out the system . You can test this for yourself pretty easily . stick an ammeter on your household vacuum and measure the current with the pipe open sucking and when your hand is over the end . You should see the current draw drop off rapidly once the pipe is blocked and the fan is no longer sucking in any air . obviously it won ' t go to zero as the motor is still spinning , but as it isn ' t moving any air it ' ll be using a lot less power .
