As a demonstration, he could float a pre-buoyant version of his idea in gaseous halocarbon C318:

No I wouldn’t think it would be that expensive, because using C318 enables creation of a quarter scale model.  It could be made with 2-meter on a side square panels, steel, welded seam.  You would lower your balloon in there, pour in the liquid C318, the stuff boils, up it floats.

 

You might be able to build something like that for in the 10k to 15k range if you have someone who is hot with a welder.

 

I am visualizing it as an advertisement mechanism.
