Machines that never stop!! Perpetual motion machines?

Β­

Ever heard of a machine which never stops! Well… Technically it’s called Perpetual motion machine. Even if we manage to create one and set it going, it would keep on going until the Big Freeze. Big Freeze is theoretically the end of everything. It’s not set to happen for another 100 trillion years or so.  If that’s a perpetual motion, then it should run for atleast that time!!! Now, you know what to say when someone says, they have built a perpetual motion machine!!

But let’s see the origin story of these perpetual motion machines. The most common of these, and the oldest, is the overbalanced wheel. In a typical version, flexible arms are attached to the outer rim of a vertically mounted wheel. An inclined trough is arranged to transfer rolling weights from folded arms on one side of the wheel to fully extended arms on the other. The implicit assumption is that the weights exert more downward force at the ends of extended arms than is required to raise them on the other side, where they are kept closer to the axis of rotation by the folding of the arms.

One of many perpetual motion machines are continuous motion that would supposedly be possible if hindrances like mechanical friction and electrical resistivity could be eliminated. But these are not those science problems where they give “IDEAL” objects.

Some part of those forces can be minimized but they can never be completely eliminated without spending additional energy. For instance superconductive metals, whose electrical resistance disappears completely at low temperature. Unfortunately, the energy required to maintain the low temperature exceeds the work that results from the superconductive flow.

There are a lot of machines like these, though there aren’t perfect perpetual motion machines, yet they are super cool to look at them. Some of them are:

Self-winding clock:  It dirives energy from changes in the temperature or pressure of the atmosphere. It depends upon the energy delivered to the Earth by the Sun and is not, therefore, a perpetual-motion machine.

Perpetual energy generator: Of course they don’t completely fulfill our requirement, yet that’s a very good idea..

Magnetic perpetual motion machines: They are a bunch of these around. Using and playing with the attraction and repulsion properties of magnets makes it even cooler..

I have a question for you, I have come across this image on the internet;);)… My question is, does it work? And if yes, how?

With all this, we can conclude that, for now actual perpetual motion machines can’t be build… And please do answer the question above;);)

  1. Didn’t try it but having thought it over, it would have to work. For the same reason if I had a magnet in my hand and a toy car in front with an opposite pole magnet on the car the car would roll towards my hand. My hand acts as the arm on your drawing.
