Hey /sci/

Is this real?

no.

lolno

stopped reading there

No - there is an equal and opposite retarding force from each magnet as positive attractive force

>> No.1207071

because there isnt' a motor underneath.

Yes.

no

You can't have a perpetual motion machine with entropy. Ever.

>> No.1207114

>>1207094
Would argue that because entropy is probabilistic, there is a chance but it's negligible.

>> No.1207123

Yes. But it's probably not what you think it is.

>> No.1207128

ok, we know perpetual motion machines are impossible, but anybody wanna comment on the actual contraption we see in the video? Does it look legit?

>> No.1207143

>>1207123
I think it's smaller than anyone could imagine; however, it's nonzero.

>> No.1207171

>>1207143
I was referring to the machine. The machine is real, but it's not perpetual motion (as evidenced by the fact that the guy has to keep pushing it)

>> No.1207176

You can have perpetual motion, even manmade perpetual motion, but as soon as you start to extract energy from the system it will start to decay into the lower energy macrostates

>> No.1207187

>>1207171
I was referring to the probability of reversing entropy in a system (perpetual motion machine in this case).

>> No.1207202

>>1207053
just for future reference OP when you find someone claiming to have an machine that breaks the laws of physics then they are full of shit

>> No.1207205

>>1207176
So, in other words, we can have useless perpetual motion.

Not perpetual and can't harvest energy from it. It slows down by friction with hydrogen atoms and by emitting gravitational waves.

>> No.1207239

>>1207176
no you can't

Oops that should read molecules, my bad.
