Algodoo

if you remove the gear, the thing keeps moving?

Like the guy was saying, algodoo has some rounding issues. If you turn up the simulation frequency in the settings, it supposedly evens out. I have not witnessed that though. It does drop, but never stops the machine from climbing. The guy on the forums are stating the most obvious thing. I guess they were awake for physics 1 when the guy spoke of thermodynamics. Even though gravity is used in the sun to produce energy in our entire solar system, they are under the impression that gravity cannot be used as an energy source. Mind you, gravity is constantly accelerating. If you have enough mass to create enough gravity, it will literally cause a reaction known as fusion. Fusion works because the amount of matter ( energy) is so vast that it creates a force that overcomes the molecular force threshold, forcing new atoms into one and releasing an extreme packet of energy. This energy usually is most noticeable in the form of heat. These physics geniuses can witness such events that power our entire solar system, yet cannot imagine how gravity could be used as a energy source. We all know the laws of thermodynamics. It is absolutely pointless to keep repeating it to people who still believe there are usages that have yet to be discovered. Save your lecture for the classroom. This is just a cute experiment and does not hurt you in any way. The fact you feel the need to justify all of this actually compliments me.

What happens when gravity sits on a rope that is held in place? It rips the rope and creates a difference in the actual molecular configuration of the rope. What happens when you take that same tension and have huge plates push together a chemical? It puts so much force on that chemical that it not only reconstructs its crystallized configuration but even at times reconstructs the entire chemical, creating compounds and even at times new elements. What happens when you put so much energy inside of an atom that it bursts? it creates an almost un-measurable chain reaction that you can only pray would be stopped by other atomic configurations that would need more energy to sustain. We could go on and on about how nothing can get more energy out then it puts in but we would also have to be fully aware of the entire amount of energy available to that system. NOt just its gravitational, potential energy but every single type of energy that could be present in the system! Its not as easy as drawing diagrams and assuming we are aware of what energy is in that damn system!!

Do not make me go on some rant about how every single practical and useful source of energy has been disregarded by the smartest of our people. We are still living in our great great grand father's shadows. The only difference is there are more bells and whistles to take our attention off of our neanderthal improvements in energy usage.

Nonononono, gravity is not the energy source of nuclear fusion. Like you said, gravity causes an acceleration ,since gravity is an FORCE, but can you create limitless energy just by squeezing a ball so tight it goes over to nuclear fission? Probably not, since once a fission happens, the internal energy of the atoms is released during the process of fusion(matter turned into energy), which can not be retrieved just like that. If you tried to keep fusing elements until you get something like uranium, you would not be able to gain even more energy by nuclear fusion, since a fission would never happen if the result would be unstable, and if one forces that process, he actually spends energy in order to create that element. Force is something that is either a result of the conversion of energy(electromagnets), or a passive presence(permanent magnets). It can be able to contain energy, for example by blowing air into a balloon and then letting go, but it can't be turned into energy since they are completely different things. Forces are the effect of energy beeing transfered through objects, may it be pushing something, or the attraction of an object near a planet, all in all energy is transfered or converted, but usually static through the whole system(if something falls without friction, the sum of the kinetic and potential energy is constant). So if you think the sun generates it's energy from gravity, you confuse some completely different concepts of physics. Gravity causes the enviroment and the energy storage, but the mass, the heat, the light and the chemical energy are the actual energy types inside the sun, with the first one constantly turning into the second and third.

I have taken the engineering classes and have heard all of this over and over again. That is the only thing I really did hear. Imagine if you ever even known of such thing as a closed system. Then we could talk real thermodynamics but we have never even created a truly closed system. So lets assume that fantasy land exist and we have not discovered all the loop holes. Maybe you could discover something. Or maybe you will just beat your head in realization that many other people have become so frustrated with trying to figure these things out that it was safe to stamp it with an impossible label!

We have not hacked every single possibility. The probability that any of this shit is happening converges to zero faster then a undefined slope could even show.

Please believe what you want. Our sciences are beyond limited and after a while amount to lists of outcomes of unknown reasoning as to why any of this actually is taking place.

If I understand it correctly, you don't believe the law of Conservation of Energy applies in this case since an Algodoo scene shows otherwise. I think FRA32 got it right, Algodoo has calculation errors. Usually they cancel out, but in this scene there must be some bias. Think about it. If you have 222 bodies with 223 constraints running at 60 Hz, then Algodoo is running at least 13380 calculations a second, each one with an error of up to 0.0166 seconds. If you make a simple scene of a circle falling 1 meter onto a plane and use script to time the fall, then you will find the time will differ from the exact value by at most 1/sim.frequency. The 1200 Hz timed fall will be much more accurate than the 60 Hz timed fall, but in no case will the number be exact. I think the same applies here. The car will go slower (in real and Algodoo time) at 1200 Hz than at 60 Hz, but in no case will the car stop.

10 for perpetual motion. Keep on going.

Algodoo is not the only reason I came up with this silly theory. It was actually on paper and I'm just seeing trying to show what I was seeing, mathematically in algodoo. The reasoning is that the tensions have not just the vertical component but two seperate horizontal components. Its not like making something like that in real life would be even close to impossible, anyways. I am just trying to relay the idea to other people who might agree that it is a little awkward. If you do not see it, move on.

You people act like peoples ideas are a sin and that I"m trying to somehow sale you on something that could or could not be possible.

Stop whining and make more stuff.

Don't want to fight. Good luck defending your hypothesis, and re-create this in real life.

Alternatively, here's how I fascinated with your perpetuum motion:

"Cool! Infinite energy, imagine if we make this in real life. Sadly, it produces tiny energy. Maybe making dozens of this will produce a reasonable energy to power a light bulb"

I may get fascinated by perpetuum motion to generate infinite energy, but it always broke that law of energy conservation. So, I've decided to generate "infinite" energy with the "legit" way (i.e. solar energy, wind energy, tide energy, etc).

So I'm a bit late to the party but it seems like this is just caused by, like many other people have said, a bug in the way algodoo works. You can remove the gear weight and the vehicle actually moves even faster. The cause of the motion are the two springs pushing the wheels apart. Not quite sure why though but you can see it for yourself. Try removing the gear or try locking the arms with the springs in place
