Why should perpetual motion be impossible? Answered
Our laws of physics are quite clear when it comes to the impossible.
You can not produce more energy within a system than what actually goes into it.
And since friction will always be a thing in our real world perpetual motion is simply impossible.
With this or quite similar reactions all good scientists end the conversation.
We know it is not possible, so why bother...
If all that is stopping are laws of physics, then it is time to redefine "perpetual motion".
Another term for it would be "free energy" as we would have to draw energy from nothing to keep it moving.
Solar cells provide free energy the same way as wind- or hydro generators, we even use waves on the ocean to produce electricity...
Perpetual motion seems to be defined by mechanical things and motion only.
And free energy seems to be defined as bogus only while ignoring the realities.
We simply can't use the same terms for everything if they are in fact totally different things....
A motor running off a solar cell would be a perpetual motor if you widen the energy term a bit here.
The impossible energy to run the motor comes out of nowhere - our solar cell generates electricity from sunlight.
And a simple water wheel in a stream will power a mill for as long as water runs down the stream....
Humanity and science say this is not free energy as we take energy from other system to make it move.
And of course it is a dead simplification anyways.
You get the picture though.
So far humanity has only managed to tap into a very few forms of energy out there in any direct form.
Solar cells come to mind first of course.
In a way they utilise radiation to transform it into DC electricity.
Then we have all sorts of mechanical energy transfer, from generators over windmills to the modern recovering brakes in electric vehicles.
Last but not least we have heat, steam engines, nuclear reactors and so on.
The laws of physics however know a few more forms of energy....
We seek out new ways to "generate" more electricity than ever before, like fusion reactors.
What we don't seek is understanding what we always had already.
All we do it to try to "generate" electricity.
It is what powers our world but it is only a tiny fraction of what is possible.
We burn fuel in a comustion chamber to make piston go up and down.
Only to transfer this motion into a rotary one to finally drive our wheels.
Most of the energy available in the fuel is wasted this way.
Making it slightly more efficient took us over 100 years....
Thinking about using the fuel more directly does not even come to our minds.
So why bother to consider any other possible form of energy to drive our world.
We are stuck in definitions no one really understands because most of the used terms have more than one use and meaning.
We fail to open our minds to other possibilities just because "that's how it is and always will be".
Flying to the moon?? Impossible!
We did it anyway....
Using batteries to provide electricity to entire towns? What a joke!
In South Australia they do it anyway and with great success as well.
Powering entire cities just from wind and solar energy? Are you joking?
Well, companies invest an awful lot of money here and they wouldn't do so if it would not make massive profits...
So why again should perpetual motion be any different?
At some stage it was hillarious to even think our world would spin around the sun.....
