Internet is full of "reaction free drives", and Arindam's is yet
another. They are all nonsense, of course, and Arindam's experiment
is very simple to disclose.
Look at this video:
https://www.youtube.com/watch?v=idsIuzEajTc
See the run that starts at ca. 9:44.
When the cylinder has moved ca. 10 cm, the rail has moved ca. 2 cm
to the right. Friction transfers the reaction momentum to the Earth
(via table and building).
Rolling friction and spring action are the mechanical forces causing
initial pushback. Sliding would prevent former.
Let us first look at what it means that the mass centre
of a system doesn't move.
Irrelevant.
Consider this scenario:
You are inertial (free falling) somewhere in space.
We will call your initial position for stationary-
You have a gun and fire a bullet.
Then we have: mv = MV → v/V = M/m (conservation of momentum)
where:
m is the mass of the bullet
v is the speed of the bullet relative to your initial position.
M is the mass of you and the gun
V is your speed relative to your initial position
If d(t) is the bullet's distance to the mass centre
and D(t) is your distance to the mass centre,
we have for all t after the bullet was fired:
d/D = v/V = M/m → dm = DM
which mean that the mass centre is stationary.
# That the mass centre is stationary follows from
# the conservation of momentum.
Now you return to the Earth.
You position your gun against a solid concrete wall
and fire it.
Rubbish.
Now you and the wall don't seem to move.
But i does! The gun is not reactionless!
M is now the mass of the Earth!
If the mass of the bullet is 20 g and it's speed is 1000 m/s,
then the Earth will change its speed by V = 3.3e-24 m/s
The Earth as a whole will obviously not change it's speed.
It will be a shockwave in the wall and the ground.
Molecules will move and mass will change its position on
the Earth. The point is that momentum will be conserved
and the mass centre of the bullet-Earth system will remain
constant (move around the Sun with unchanged speed)
Blah
Yes the rolling friction to begin with pushes the whole system
backwards. If the armature slided then that would be less. The spring
used to accelerate the armature also creates a backward reaction. The
rolling is necessary to prevent welding. If it welds then it cannot
accelerate. The more sticking by welding happens meaning more sparking
less the force on the armature.
You get it backwards.
You try your best not to get it.
The friction pushes the Earth to the right, and the momentum
of the cylinder will be equal to the momentum transferred to the Earth,
Which is not happening. There is violation of momentum with internal
force as a net velocity is obtained for the system.
mv = Ft
where:
m is the mass of the cylinder,
v is the speed of the cylinder when it has moved 10 cm,
mv is the momentum of the cylinder when it has moved 10 cm,
F is the friction between rail and table (independent of speed)
t is the time it takes for the cylinder to move 10 cm.
Blah
Anyway it is shown from the 1s video that despite the initial backward
motion the centre of gravity of the whole system accelerates and gets
shifted thereby revising physics. Inertia is violated by this new
invention, the low voltage heavy armature rail gun. It shows a new
effect - under this geometry the Lorentz force does not have an equal
and opposite reaction.
Nonsense.
A well known experiment is to have a heap of wire on the floor
and send current through it. The wire will then become a circular loop.
This is the same phenomenon as the Arindam drive.
Nobody has ever had the idiotic idea that this motion of the wire
prove that momentum is not conserved
Then the cylinder is moving all the way to the end while the rail
does not move at all.
Yes that shows that the Lorentz force accelerating the armature in this
novel experiment never done before does not have an equal and opposite
reaction. So while the armature moves that force does NOT push the whole >>> system back.
Nonsense. Didn't you read what I wrote?
You must be incredible naive to interpret this as there is no reaction.
The blatantly obvious explanation is of course that the force on
the cylinder is to weak to overcome the stiction. So the reaction
momentum is transferred to the Earth.
The stiction will be equal to the accelerating force, and will
transfer a momentum to the Earth equal to the increased momentum
As it does not the centre of gravity of the system accelerates violating >>> inertia and revising physics. A cyclic engine (will take some money to
develop) will be a reaction less motor making jets and rockets obsolete.
Do you also believe in Santa Clause ?
Arindam's 2017 videos show details about the design of faster than light >>> craft for interstellar travel.
Quite.
When you revise physics ad libitum anything is possible.
WOOF woof-woof woof woof woof-woof

When the cylinder hits the stopper at the end, the whole assembly
moves 4 cm to the left, and the friction will transfer the momentum
of the cylinder to the Earth.
The centre of mass of the assembly-Earth will not move.
This must be the least effective way to accelerate a cylinder
anybody has figured out.

I always liked Larry Niven's take on it:
Trying to change one law of physics is like trying to eat one peanut.
