Perpetual motion machine

[userblade]

hey, this is my first true post, so as a result, I can't use images, but I'll try my best to illistrate a perpetual motion machine that I can't find the flaw in. hopefully you will be able to help me out.
My idea consists of 8 magnets, 6 of which are set up on a wheel and two of which are stationary and lie below the wheel. below is my attempt at a text-image.

could someone please explain to me why this wouldnt work?

[userblade]

it would seem my image got distorted.....

[userblade]

apon reconsideration, I think ill either wait until I can post images or just ask my physics teacher, sorry everyone.

No... no worries at all. Actually, I hope you'll post your idea when you reach the user level of being able to post the picture.


However, don't magnets eventually... I don't know... demagnetize?

a perpetual motion machine I find is a waste of time. It needs to be at least 101% effiecient in order to do work, and if it can, it will be such a low amount of work you'd be better off collecting batteries to power something.


I recommend putting your effort into highly efficient working devices. For they may not last forever, but either does material. Ie. Make a car that lasts for a month before needing maintainance (ie charge/fuel/ etc) and you got yourself something close enough to 100% efficient that we can damn well call it life related perpetual.

I've designed a vehicle sysetm that I beleive is a good concept for starters.

It uses waisted energy, (I find thats the biggest problem with todays things, wasited energy, and is where you should direct your inventiveness), and directs back into the system to help propell. Ie, heat, pressure, force, design, etc.

One more example, it is possible in my opinion to develop extremely fast water traveling devices (kind of like a boat) that has amazing low drag, alowing it to efficiently travel at amazing speeds. This concept I think could be converted to the air for extremely fast speeds with lower drags. I may share the details eventually, but only after I do some prototype testing to see if my estimations are accurate.


So anyway, thats my advice, take it as you choose.. Put your skills in a useful place... not in a phantom fame fantasy (seems most perpetual device inventors I've come across think about fame and success alongside the device)

Btw, I will reply to your design another time.

2nd law of thermodynamics... You don't leave a bunch of toys scattered in a child's room and return to find them ordered in one corner unless energy was entered back into the room/system (i.e. entropy elsewhere increased)...

Userblade: the earth is basically a perpetual motion machine going round the sun. But perpetual motion isn't much use unless it can make something else move, then you can use it to get things done. Any perpetual motion machine you can think of would need to be able to move itself faster and faster and faster, then you could bleed off the excess motion to do some "work". Sorry, but it just isn't going to happen.

The earth will not go around the sun for ever, even if the sun had infinite life. The tiniest bits of 'dust' will distort the motion of the earth, which can cause it do eventually spiral into the sun over time.

Even this 'perpetual' motion machine will encounter some or the other dissipative force, which shall cause energy loss from the system.

Just how, I will be able to say when I figure out the structure of your idea properly.

I'm going to take a guess and assume that the OP means something like this:
