Hold on.
Friction, Friction, Friction.
The balls would have a tendency to slow down in water, and the resistance of motion would catch up to it.
Also, let's add on the wheel's tendency to stay still.
And the magnets in the generator being forced to move.
I'd be surprised if you could get a single hertz out of that gimmick.

Besides the spelling and the magical waterproof seal? The buoyant force pushing up against the ball exiting the air chamber.

The friction would still exist and (if this is to any form of scale) the friction would still be proportional to the energy being pushed into the device - if one would crack open any physics manual, the formula for friction is:
Ff = μ FN
(or "Force Of Friction = Friction x Force")
Friction is the result of all objects' tendency to resist motion, and is always acting in the opposite direction of the force that is driving it. You would perpetually need twice the amount of energy to overcome the total friction of the device connections at every point. This eventually leads to the device's undoing -
it would run about 10 seconds before it halted. But would it be considered a mechanical error, or human error (retardation of a developer)?

No it isn't. Water pressure pushes on all sides. The net force on each ball is related to the difference in pressure between the top and the bottom of the ball. The difference in pressure from air to deep water is much greater than the difference from deep water to slightly less deep water. The force will balance. Heh... Star Wars...

You're just as wrong as he is.RichardMNixon said:
The intermediate buoyancy is based upon density, not pressure. If that was the case, then we could all float in the water without flailing our arms to go down with a breath full of air no problem. However, the air in our lungs decreases our density by putting space due to air (a lighter material). We float because we are less than water. Same for the balls.

You fail at math.M31asWake said:
Energy produced = Energy put in - Friction
What excess energy? :/
I have an idea. Take a car battery, hook up both ends to each other and light up a cigarette as it recharges itself. Make sure you're at a gas station. You'll be safe - I promise.

No, it isn't, because as I explained the force up on the ball at the air-deep interface is much, much greater than the force on any individual ball. It will balance out.

Potato, potahto. Density is a convenient way to think about buoyancy, but there is no "density force." The buoyant force exerted on a floating object is caused by pressure. Pressure of a static fluid = density*gravity*height. Since one side of the ball is at one height and the other side is at a different height, there will be a difference in pressure. Integrate that pressure difference over the area of the floating object and you have your buoyant force.

M31, stop trolling. FRIENDLY REMINDER.
Also kids, don't feed the trolls. It's got a face from a 4chan meme for science sake.

PRESSURE!
Interestingly this reminded me of a renewable energy scheme which uses the temperature difference between surface water and water further down in the ocean in a process akin to refrigerator coolers or heat pumps but in reverse - instead of using energy to produce a temperature difference a temperature difference is used to create energy.
I just looked it up and it turns out that Wikipedia has an article on it (surprise, surprise!):

Nepphy also talked about infinite energy though he did not know it. DPRjones came to this shocking conclusion.
Surely the issue here is getting the balls into the water in the first place.
Ie, the valve on the bottom left side simply cannot work as demonstrated. It will take an equal ammount of energy to put a ball from the pit into the water as will be provided by the balls subsequent rising (I think, sorta making this up by just thinking about it), but of course you lose energy in the process due to friction etc.
##edit: Really should have read this thread before, I see this has been explained already.

Err that's cool though, I didn't get it until you typed that out, RichardMNixon's explanation just confused me. Now I get it though.
