Can some one explain CG to me a bit, for example,

I have a 1 meter stick, at each end is a 50cm wheel with a 1kg weight inside (alternator attached to the inner of the wheel so when the wheel spins the alternator turns).
as the weight will always be at the bottom of the wheel, that would throw the CG down the 1m stick by 25cm.
would that 25cm of off CG be enough to loose any potential power gains?

Second question, regarding the picture below (roughly drawn on paint (im not pc world guy)),
with the electro magnets only kicking in when they are needed, would that cause ou or not?

im sure both these have been tried and tested before, they are just something that have been in my mind for a while.

sorry for not finding the correct places, I just wanted an active forum with allot of expertise looking at it daily.

did a modeling of the magnet wheel roughly based on the picture, with some addition stuffs or changes.
u might want to also consider the magnet wheel in outer-space situation, for the fun of it... no gravity, weightless, easy to push/repel with minimum strength (vice versa, easy to stop), with proper setup can have almost zero surface friction (but have magnetic friction, and if generating work, electrical friction, and other other problems

)

PS: the thread title CG Showcase, the CG in this case, means Computer Graphics, not center of gravity, just to clear out some confusion and misunderstanding. Center of gravity, learn it, study it but don't really understand it, so i would suggest u to open up new thread to ask the question, and other questions.

Thank you Helloha.

Oh HAHA yeah I got the CG misunderstood. haha. oh well.
I decided to try it and after buying all the things needed found out that the magnets i used were way too strong for the electromagnet. the magnets just stuck to the elec mag. haha. never mind. something I have learned.

just made a picture of what the other thing with the CG possible problem. I can see it will definitely be a problem so wont continue with that (shame as I have 2 large wheels made from 30mm bullet proof glass and the frame made from thick welded steel)

Thanks for the help any way.
back to the drawing board.

using wind force to simulate the repel force of magnet (the simulation program do not have magnet feature)

although the wind effect can set within a range, but all area inside the range will be affected (for magnet, it should be around the magnet's area). The wheel and balls are affected by the wind force (only the balls should be influenced by magnet).

ended up a funny and interesting result (can see the balls falling out of the wheel one by one

), the wind force pushes the wheel more than the balls, in turn the wheel rolls the balls rather than the opposite.

Draw a horizontal line through the axle and then see how many balls are above and below
the line and you will see more below and therefore it is bottom heavy but would better
be one side heavy. Some minds can see art in everything but my mind after many failed
devices sees balance or wheel mass.

Looks great but its off balance at the wrong place.

The balls in the inner circle would be bottom heavy if you draw a line through the axle but
the outer circle warped rectangles might have some build merit.
In the outer circle there are 7 balls above the axle and 9 below - not good.

I do like the right side weight shift but there is also a bottom heavy potential rotating from
4 oclock to 8 oclock.

What does the simulation show?

the 'hinge constraint' function in the simulation software tends to create chao/undesire movement (this problem has been bugging me for months, never like the 'hinge' along with the 'spring', 'rope', 'soft body' and on and on ..... -_-!!! .... signs ... still need to use the 'hinge' for the mt24, mt25..... >o< )

So many nice drawings. Too bad that closed looped gravitywheels never will produce excess energy. No need to explain why.
