The ball is dropped on the red line, suppose to be some flexible material like rubber. The blue box is slightly heavier than air making it rest at the bottom. As the rubber is pressed inwards the air pressure inside the outermost box increases making the blue box lighter causing it to rise. The blue box hits the ball back up and as the rubber returns to its original state the air pressure returns to normal causing the blue box to sink to the floor.
I understand that its not practical, ie, the blue box might not rise fast enough to hit the ball, but explain why the theory is incorrect.
Leo Young
Why do you think increasing the air pressure in the big box would make the blue box rise?
I'm pretty sure increasing the air pressure would make the blue box stay right where it is
Has can't stay in the form of a "box", regardless. It will expand to fill the volume of its container, the partial pressure of the air is what keeps the blue box down near the floor
Nathan Cruz
nothing wrong with that theory where:
desnity of air = x density of ball = x + e density of block = x - e
lim(e->0)
Logan Clark
Wouldn't the increasing pressure compress the box too, making it denser?
But if not, then assuming no energy losses perhaps you could get that thing to oscillate forever. That's not what people usually have in mind when they're talking about perpetual motion devices (an idealized mass on a spring would be a perpetual motion device by that definition).
Levi Lewis
>an idealized mass on a spring would be a perpetual motion device by that definition
But in addition, the blue box rising up and down should create additional energy, or not?
Justin Sanders
Eventually, assuming the premise is correct enough energy would be lost to the box it would stop.
Isaiah Anderson
When the ball is down, the box is up, and vice versa. I think the total energy stays constant.
James Hall
Tell me why this wouldn't work.
Sebastian Ortiz
water is applying pressure on the seal, so the ball has difficulty entering.

Here I'll make it simpler for you. Put a mass on a spring, pull the spring, and release it.
PERPETUAL MOTION
Lucas Long
OK OP you don't understand what perpetual motion is. It's not just something that moves forever, you have to be able to extract energy out of it. As it stands, the ball is just bounced back to where it was at first. Where is the gained energy? If perpetual motion was just something moving forever, I'd have a simpler example: just have a ball bounce elastically on a surface. The ball will bounce forever, at the same height. Unfortunately that's not what we call perpetual motion.

Bentley Jones
You know I actually thought this one up when I was like 12 and it took me a long ass time to figure out why it wouldn't work

I miss troll scientist threads
Christian Long
Because there's no such thing as a rubber line / sheet that is perfectly elastic. Every deformation is going to take some of the ball's kinetic energy and convert it into heat. In other words, have you ever seen a rubber ball that can bounce forever on concrete, even in a vacuum? No.
Dittos for deforming the air itself in the box. Some of the energy to raise the pressure is going to be transformed into heat.
Christopher Hernandez
> Implying it has to be a seal. Thats a desperately tryhard response to account for an inexistent energy loss.You can simply put airlock gears that rotate as the balls go upward.
Henry Walker
>gears are exempt from water pressure
Noah Martin
shit would just turn into water and piddle out
Matthew Johnson
> tries to account for less than a liter of static water pressure You know the buoyancy is a much stronger force right ?
James Hughes
>not adding the buoyancy of the balls to the overall force on the gears >what is Newton's third law
Colton Gonzalez
Buoyancy is an upwards force you fucking retard, water pressure is a downwards force, you don't add them together. Go get highschool physics before talking about physical laws.

Inefficiencies in the system that draw energy out:
>The stretching/reforming rubber
>The inelastic impact of the blue box on the floor of the bigger box
>Resistance as the blue box moves up and down (Not on the ball - you can place the system on the moon. But the blue box must move through a medium that pushes it upwards)
>Flexing walls of both blue and white box as air pressure changes.
>Flexing wall of the ball as it hits the rubber.
Each cycle, these five things will draw some energy out of the system as heat.
Tyler James
That would be the case if the blue box wouldn´t move. However when the ball hits the rubber the air pressure inside is increased making the blue box move. This creates energy no?
