Magnet motor?

    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. ;-)

    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.

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

    for an actual working model, patents etc. have a look here.

    Best viewed with open mind.

    The main problem is that perpetual motion machines don't work.

    The 'magnet motor' is distraction for fuckwits who slept through science at
    school.

    " TEN D CLASS SHARES IN LUTEC ARE NOW AVAILABLE TO SOPHISTICATED INVESTORS ONLY.
    PRICE IS AUD 100 000 EACH. APPLICATION MUST INCLUDE A LETTER FROM YOUR
    ACCOUNTANT CONFIRMING “SOPHISTICATED” INVESTOR STATUS.

    Uhuh.

    " The reference to "sophisticated investors" is a way of circumventing the legal
    requirement for a company to issue a prospectus if it wants to make a public
    offer to sell shares. A prospectus has to be approved by the relevant
    authorities before being issued and there are severe penalties for inaccuracies
    in a prospectus. As a reasonable case could be made that statements like "A
    TYPICAL LEA SYSTEM IS 440% OVERUNITY" could be seen as inaccurate if the
    reference is to something existing in the real world, it is very handy that
    there is a loophole in the law which might allow the promoters of such a scheme
    to gather a million dollars without the inconvenience of having to issue a legal
    document saying what they want the money for. A "sophisticated investor" is a
    legal fiction. It is someone who is assumed to be capable of making investment
    decisions based on an independent assessment of the risk, whereas a normal
    investor needs to be told things like financial details and projections,
    scientific evidence for scientific claims, and the truth.

    I thought that the relevant authorities might like to know about Lutec, and you
    can see complaint number 75880137 to the Australian Securities and Investments
    Commission here."

    And this was the professional reply from a company trying to raise a million
    dollars from investors:

    Dear Donkey,

    we don't have perpetual motion, I don't mined you having a fantasy. Further, you
    may be able to read the words, obviously you don't understand them.

    Have a shit day donkey crook, donkey moron.

  16. 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

    Snipped the rest. It must be nice on your planet.
     
  20. 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.
