https://www.msu.edu/~brechtjo/physics/airTrack/airTrack.html the above applet you posted a link to proves that reactionless propulsion is possible and that is basicaly what this has all been about anyway.

set the red cart mass to 5 kg , initial velocity to 40 m/s

set the blue cart mass to 1000 kg , initial velocity to -4 m/s

set elasticity to m1 = m2 elastic

the results are as follows.

the red cart -47.56 m/s

the blue cart -3.56 m/s

the red cart ( 5 kg mass ) accelerates from 40 m/s to -47.56 m/s

the blue cart (pipe / rails) do not stop they only slow down.

to -3.56 m/s from -4 m/s

if you are using multiple rail and mass sets.

I increased the lenght of the pipe / rails to 1000 m

but to make this easier lets say the new pipe / rails length is only 400 meters.

400 / 20 = 20

say 20 masses are accelerating at any given time.

so you would have 20 masses free floating and 1 mass in the turns at each end.

a total of 42 masses.

the 20 rails have a combined mass of 1000 kg

each mass that is accelerated has a mass of 5 kg

20 x 5kg = 100 kg

each mass starts at the begining of the 400 meter rail

and they are timed to begin acceleration so that there will be 20 masses accelerating at any given time.

1 is launched then a time passes then another and so on.

this way the distance of the 5 kg masses will be spaced in their respective rail gun so that only one 5 kg mass enters the 1st turns at a time.

each mass is accelerated to 40 m/s

this in turn accelerates the 20 rails to -4 m/s

because there are always 20 masses being accelerated at any given time.

20 x 5 kg = 100 kg

so each time a single 5 kg mass collides with the pipe / rails that is traveling at -4 m/s the mass ( red cart )

reverses direction and has a velocity of -47.56 m/s

the pipe / rails does not even stop or reverse direction it only slows its velocity from -4 m/s to -3.56 m/s

so theres proof that it will work.

but lets not forget that there will also be a mass passing through the 2nd turns as well so

so change the mass of the red cart to 1000 kg

change the mass of the blue cart to 5 kg

copy the resultant -3.5621890547263684 velocity from the blue cart to the red carts initial velocity

copy the resultant velocity -47.56218905472633 from the red cart to the blue carts initial velocity

run it and you see that as the two masses pass through the 1st and 2nd turn they cancel each other out.

like I have always said.

chances are that once the system is in opperation the pipe never would even slow down...

results are as follows

red cart -4 m/s

blue cart 40 m/s (39.999999999999964) actual

now to make it so that there is no movement before your ready to go , you could have accelerator rails where the masses free float , and synchronized launching of the masses from the + direction rails and from the - direction rails would cause the pipe / rails to not move.

if you want to go forwards or backwards you just shut down the accelerator that you dont need to travel in that direction.

and it wouldnt cost more than 18 billion to build and it would be as if our technology isnt still stagnated.

using the same exact space propulsion as we have for the last 60 or 70 years or so.
