It will add to the mass of the accelerator,

but a type of vaccuum system can suck in

the particles again once it reaches the

end, hitting the surface of the electromagnetic field.

 

Why the outer shell is an energy field is because,

it's not propulsion if the particles are contained

within. I'm guessing the energy field, despite

being a shield itself still permits interaction

with the hollow space.

 

Also does not increase the mass of the overall

'ship' by much. But it depends on the mass

of the particles, it's acceleration relative

to the accelerator/ship itself.

 

What do I know. I'm just guessing by intuition.

 

 

In any case, I will continue to try and finish

up the chores. Sometimes my mind gets stuck

in a unnecessary loop.

 

I have to get out of it.
