: Saw this on free_energy Yahoo group a week or two ago... Some observations:
: In the video there are a few places where you see the little doohicky in action...
: ||0:56: you see it only from a distance and you see only one "pulse" of thrust. The narrator also says "it kept on accelerating of it's own accord" but that behavior is not evident in the video. On the contrary, the car apears to slow slightly as it reaches the end of the table.
I wish the video was better :*(
: ||1:10: you see the car move across the table, pulsing several times, apparently keeping itself moving... but if you look carefully you'll see that each time the weight shifts back for another pulse the car slows a little, and then again when the weight moves forward... and then it speeds up when the weight hits the front of the tube.
This is the part I "really" watched-the inner tube seems to be
on springs, wanting to be in the center of the outer tube(s)
(the 2 main sides with the hoses sticking up) In that one test,
I saw the inner tube move one direction, and bounce around a bit,
like it is stabilizing...near the end of that part, it seemed
to stop moving inside the outer tube, just shifted to one side
with the ball bouncing back and forth inside...meanwhile,
the cart did seem to accelerate or at least maintain speed...
This is totally normal as far as physics go and proves there *are* reactional forces happening in the car.
Of course...I wonder if compressed air, being a gas, can direct the force down or something to make it 'disappear'
: The troubling part is that they keep saying that the little car *accelerates* on it's own. I saw no acceleration in the video, only a large initial bump that sent it to the end of the table, or else several small bumps that sent it to the end of the table.. but it was slowing as it reached the end.
The run is too short, the video too crappy to really
see anything too well...
: I'm also skeptical about the one physics guy and one outside testing facility that, according to the narrator "appears" to have confirmed the tests.
I think this guy is from South America? At least he didn't
ask for funding money...
: Not saying that it's a fraud, but I'd need to see alot more video of alot more tests under different conditions to be convinced. That video doesn't show a "reactionless" drive that accelerates on it's own, it shows reactional forces and slight slowing down as it moves. My opinion, without seeing anything else, is that it's just like one of those highly balanced wheels that almost appears to have OU... but it's just very efficient at conserving the initial energy imparted into the system.
: The only way I can see this working as advertised is if the moving ball (or tube) is not connected in any way to the rest of the car, kind of free floating on air or something, so that it can move back without pushing against the car anywhere and only impact the car when it hits the end, but even then... when it moves forward it would have to push against something to do so... if the air pressure pushes it foward then the weight would, in effect, be pushing against the back end of the outer tube so... nah... I don't see it happening... I'm going to take the skeptical side for now, until there's more video or testing or something.
