I violate law of energy conservation

Let's say we have a helium balloon carrying total weight of 1 kg.
We set up 2 stations. Pumping station on the ground and deflating station at certain height.
We pump the balloon until it start to float up. We catch it at deflating station at height H.
Now the energy we gain is potential energy of the falling balloon which is mGH.
The energy require for pumping and deflating a balloon is set! If any.
The height H can stretch as high as you want to! => mGH is a linear increasing function.

Cool -- perpetual motion finally!

But seriously, if this is a closed cycle that runs continuously, how do you get the helium back down to the ground to keep refilling the balloon...? Pump it, right? And the energy you could get out of the balloon motion gets used up (plus more) in the helium pumping.

Oh well, still no perpetual motion.

Well, there's no problem in getting the helium back down. Just make a sealed tube that contain air lighter than helium and let gravity do the work. Yeah, still the sticky point is the pumping the balloon part. I suspect the energy require to pump the balloon is theoratically exact as the maximum height the balloon would reach. Oh well, I'll find another way to break that law.

Your time really would be better spent on another pursuit. Right now, you're playing a lottery with no jackpot!
