Is it possible for a weather balloons filled with helium gas to lift the weight of itself and a helium tank(highest psi possible) which can fit the volume of the lifting gas in it?
Assuming a typical weather ballon material is used as the ascending vehicle would the balloon with the helium pumped back in the tank fall down to the earths surface?
P.S. In water the weight as well as the surface area for that weight determine its buoyancy - ships etc. A 5tons of dense block steel would sink in water but spread around over wide enough area it should float instead.
Wouldn't the same thing apply to the difference between a helium gas filling the larger volume of the balloon vs the high pressure compact volume storage vessel?
