would this work ? (perpetual machine)

Surely as soon as the word "Perpetual" appeared in the title the easiest answer was "No, it will not work".

Although it wouldn't work, it is interesting to think why it wouldn't work. This one was actually quite good, and I had to think a bit about it. I see it more as a little puzzle than just a simple NO.

One of the laws is that energy can only be converted, it cannot be created or destroyed. The universe has the same amount of energy, always. (famous last words..)

yeh, but perpetual machine would have to create energy to keep its self going.. To combat friction, air resistance ext? So it would never work?

Eg. you give the machine a push to get it going to keep going and never slow down more energy must be added so your creating energy.

Good thing these people are running countries.

I like the last line, "It is, after all, tougher to ride the bike when the dynamo is running." I wish we could see his reaction or argument to that.

That was a great response. Even though it wasn't too much tougher, you were providing power to make the thing run in the first place. :)

Wow. I haven't seen those things in ages!

The balls put the chain in tension. Thus any submerged ball experiences a tension force downwards. This will match the bouyancy force upward, so the system will pretty much stay in equilibrium.

Good call.

Doesnt physics state that perpetual machines will NEVER work? As you cant create energy from nothing.

Physicists state a lot of things. Periodically they decide they've got things wrong and change them en masse. The laws of thermodynamics look pretty convincing so far, but I believe they are still entirely empirical. As such, there's a decent chance we've missed something subtle. I think there's a circular definition hidden within "entropy always increases" and "time is forward flowing", and there may also be problems with causation at some point.

Anyone know of a theoretical basis for thermo? It's been a while since I've looked at real physics
 
Hire the lecture theatre at any World Famous University. That is usually possible. Go with a friend (a stooge). Present your idea to the delegates (just your stooge). Ask the audience (your stooge) if it will work. Prime him to say, "Yes it definitely will".

Now you can go to seek investors, stating that, "At a recent symposium at the World Famous X University all delegates unanimously agreed that this new invention will work."

have you ever played with techno lego as a kid and tried this troll science stuff b4? lol... it doesn't work, for infinate energy you must have an energy sauce... try power ketchup, haha think that has more power in than troll science.

on a serious note now,
for a system to keep itself sustained i can only guess you'd need a system in which has 2 alternating power sources in, so while 1 runs the mechanics it also charges the 2nd battery up, when the first battery starts gettin flat the other battery then starts to drive and the previous battery shuts down and gets charged by the 1 thats just enpowered, obviously you need some power to input in the first place

I tried the dynamo theory back when i was a kid with technic lego, i tried havin a car continuously run itself from a dynamo system, the rig looked pretty impresive tbh until i tried to activate it... that was definately a case where numbnuts had to push the car... haha
