an electrostatic propulsion system concept
Alex
Here is an electrostatic propulsion system concept.
http://knol.google.com/k/alex-belov/electrostatic-propulsion-system-concept/1xmqm1l0s4ys/15
This electrostatic propulsion concept based on flow of electrons
inside vacuum tube.
This system has two electrostatic generators. Theirs electrostatic
fields make a flow of electrons inside vacuum tube. This system has
two flows of electrons. First main flow of electrons has a spiral
path(long path) where electrons have very high value of velocity
(close to light speed). Another return flow has straight line
path(short path) where electrons have low value of velocity. These
flows of electrons have identical amount of electrons during certain
period of time. Base on mass relativity, the electrons with high value
of velocity have bigger value of mass than electrons with low value
of velocity. The mass difference between two flows of electrons should
move electrostatic propulsion system center of mass into opposite
direction of main flow of electrons with spiral path(long path).
Please take a look.
Thank you

Note: You have re-invented a common idea that fundamentally does NOT work as you seem to believe it does. However, I will permit the topic to encourage discussion and education.

When people started confusing what relatvisitic mass really means. Can someone weigh in with the math? Thanks. GdM

They never did. It's just that there is never a shortage of students who
think there must be some sort of loophole that can be exploited.

I can't weigh in with the maths at the moment, but I can make a couple of
points. To get the electrons to move in a helical trajectory you'll need
more than a simple electrostatic field; a magnetic field would do. But
you still have something like a synchrotron--the circular component
of the electrons' motion will cause them to radiate away energy (and hence
momentum) at a pretty high rate. You'd need a power source to make up
for the losses. And, yes of course, overall momentum will be conserved,
meaning no net thrust.

So a simple way to understand conservation of momentum, is to note
that forces are aways between things. So when i use an electric field
to accelerate an electric charge. The forces are between the mobile
charges and the charges bound in the electrodes. It does not matter if
the the charge gets more "massive" since then it takes longer to
accelerate and hence the force on the bound charges is also over a
longer time, and thus the same amount of momentum is transfered to the
acceleration structure as to the charge.
So in the first case (not spiraling) it is easy to work out the net
momentum on the electrons. But the same amount of momentum in the
opposite direction was applied via electric force to to the whole
craft. And then the electron hits the top plate and puts all its
momentum back. The net momentum change from the right side is zero.
On the spiraling side we have the same thing no matter how fast we
"spiral". First energy is conserved. So the max speed of electrons on
both sides is determined by the potential difference. We will ignore
loss from synchrotron/Cyclotron radiation (these in practice would be
large) and assume you use cross field to produce the spiral (to
produce a helix you would need to inject electrons with some sideways
velocity). In this case the electron go nowhere (magnetic
insulation!). We can come up with different spiral patterns, but with
no losses you get no momentum change. the electrons start with no
momentum. They finish with no momentum and the net change in momentum
is nill.
Remember that rest mass and relativistic mass are not the same thing.
The relativistic mass depends on the frame of reference. The rest mass
does not. And that momentum is a vector!
