I have a problem with my magnet motor design. It is based on a wheel continually rolling down a sloping disk. The disk is tilted up by repelling magnets, creating a pushing wave directly behind the wheel.
The magnets are repelling each other okay, but will NOT slide easily past each other.
Is there a way to fix the problem?
Thanks for your time.

Perpetual motion machine?
Oh, how ideas persist.
The easy answer is that it can't be done, by virtue of conservation of energy. The hard answer would involve really analyzing all the forces involved, to discover that before a magnet can push, you have to pull a bit (or something like that).
Where'd you get the erector set?

Perpetual motion requires 29 magnets on your disc, you only have 28. Sigh, it's always something. ;-) Mike

No, no, no! The number of magnets required is determined by a formula which included pi as a multiplier in the final answer. So it will never work in this dimension as you can't get a fractional magnet!

I forgot to mention - plug that formula into Google, and the answers to all of your questions will become clear.

There Ain't No Such Thing As A Free Lunch - but sometimes you get lucky, and discover half a pizza in a pizza booth that no one wants anymore...
... and you can hydrolyze it with alpha amylase, feed it to yeast, distill it, run it through zeolite, and now you have neat ethanol.

I think this is the one we need work on, hydrogen from bacteria eating waste.

Hard to store gaseous hydrogen, plus most cars can't run on it.
Oh, wait, we can liquefy it (turn it into methanol):

If we had cheap hydrogen, we would find a way to store it.
Not yet.

Um, So I guess you believe that magnets cannot do work? Guess you never picked up anything with one? What about solar energy? or nuclear energy? They are even better than perpetual motion... its free energy.
Do you really think that if we didn't have "perpetual" motion that we would even be able to do anything? The human body is perpetual motion.
If you talk about getting more energy out than you put in then its easily done and done all the time(many people, your probably one of them, do it all the time while "working"). If its a closed system and you take the net energy then its a different matter.
Nuclear energy, solar, energy, and the human body are "perpetual" for all practical purposes. Actually perpetual motion is a hypothesis and not a fact. It is also not conservation of energy. It only supposes that the entropy is 0 and not negative. The 2nd law does state that entropy increases over time but technically it could be constant too(quasi increasing). The subtle point I'm trying to make is that for pratical purposes it depends only on maximizing efficiency.
In any case, you are forgetting, I guess in your old age!?!, that magnets have the ability to do work. Something created the magnets and did work on it and those magnets can use that energy to do work(same principle as nuclear energy or chemical energy or whatever else). This is why natural magnets loose there magnetism over time.
So for the original post, it is possible but chances are the friction is to much for the magnets. One could get practical perpetual motion by using solar energy to overcome the fricition. It might not technically be perpetual motion according to physics but no one would be around to see it stop.
Hell, we don't even know if gravity is conservative but we treat it as so for all practical purposes. I guess your problem is that you have to distinguish free energy devices from practical perpetual motion. The guy isn't claiming is device will run for ever and probably doesn't care. I'm sure he would be happy if it ran for a few hours.

Yes I can, did it the other day. Took a big hammer and....
WACK!
and I had hundreds of fractional magnets.
What's so cool is you don't loose any at all!

Try not to think about the magnet moving, use the flux - it has a small amout of force, but its moving at the speed of light

Yes, it is... I'm my planet people actually use there brains and actually read the entire post.
Its funny how you quote something entirely out of context just to make yourself feel smart.

I guess you expect to impress people with your psychology analysis? Go back and learn some physics instead.
